Attributes

JET Custom Elements

JET components are implemented as custom HTML elements. In addition to the component attributes documented in this page, JET components also support standard HTML global attributes like id and aria-label.

The JET data binding syntax can be used to define both component and global attributes through the use of dynamically evaluated expressions. All attributes (component and global) support attribute-level binding by prefixing the attribute name with ":" (e.g. :id="[...]"). When using attribute-level binding, all expression values are treated as strings. Additionally, component attributes support property-level binding by using the attribute name directly with no ":" prefix. When using property-level binding, the expressions should evaluate to the types documented by the corresponding attributes. Property-level binding is strongly recommended over attribute-level binding for component attributes.

A detailed description of working with custom HTML elements can be found in: JET Custom Element Usage.

JET InputText Component

Description: The oj-input-text component enhances a browser input type="text" element.

<oj-input-text></oj-input-text>

Validation and Messaging

An editable component runs validation (normal or deferred) based on the action performed on it (either by end-user or page author), and the state it was in when the action occurred. Examples of actions are - creating a component, user changing the value of the component by interacting with it, the app setting a value programmatically, the app calling the validate() method etc. At the time the action occurs, the component could already be showing errors, or can have a deferred error or have no errors.

These factors also determine whether validation errors/messages get shown to the user immediately or get deferred. The following sections highlight the kinds of validation that are run and how messages get handled.

Normal Validation

Normal validation is run in the following cases on the display value, using the converter and validators (this includes async-validators) set on the component, and validation errors are reported to user immediately.
  • When value changes as a result of user interaction all messages are cleared, including custom messages added by the app, and full validation is run on the UI value. The steps performed are outlined below.
    1. All messages are cleared and messagesCustom property is cleared
    2. If no converter is present then processing continues to next step. If a converter is present, the UI value is first converted (i.e., parsed). If there is a parse error then the messages are shown and processing returns.
    3. If there are no validators setup for the component then the value is set on the component. Otherwise all validators are run in sequence using the parsed value from the previous step. The implicit required is run first if the component is marked required. When a validation error is encountered it is remembered and the next validator in the sequence is run.
      • NOTE: The value is trimmed before required validation is run
    4. At the end of the validation run if there are errors, the messages are shown and processing returns. If there are async-validators, those errors are shown as soon as they come in, and not until all validators, sync and async validators, are complete, does processing return, that is, value and valid are updated. If there are no errors, then the value property is updated and the formatted value displayed on the UI.
  • When the validate method is called by app, all messages are cleared and full validation run using the display value. See validate method on the sub-classes for details. Note: JET validation is designed to catch user input errors, and not invalid data passed from the server; this should be caught on the server.
  • When certain properties change through programmatic intervention by app, the component determines whether it needs to run normal validation based on the state the component is in. Refer to the Mixed Validation section below for details.

Deferred Validation

Deferred validation is run in the following cases on the component value using the implicit required validator if required is true, and validation errors are deferred, i.e., not shown to user immediately. Refer to the Showing Deferred Messages section to understand how deferred messages can be shown.
  • When a component is created and it is required deferred validation is run and no messages are cleared prior to running validation. Refer to the Validators Participating in Deferred Validation section for details.
  • When the value property changes due to programmatic intervention deferred validation is run, after all messages and messagesCustom property are cleared.
  • When the reset method is called, deferred validation is run after all messages and messagesCustom property are cleared.
  • When certain properties change through programmatic intervention by app, the component determines whether it needs to run deferred validation based on the state the component is in. Refer to the Mixed Validation section below for details.

Mixed Validation

Either deferred or normal validation is run in the following cases based on the state the component is in and any validation errors encountered are either hidden or shown to user.
  • when disabled property changes. See disabled property for details.
  • when refresh method is called. See refresh method for details.
  • when converter property changes. Not all EditableValue components have the converter property. See the sub-classes that have the converter property for details, e.g., oj.inputBase#converter.
  • when required property changes. Not all EditableValue components have the required property. See the sub-classes that have the required property for details, e.g., oj.inputBase#required.
  • when validators property changes. Not all EditableValue components have the validators property. See the sub-classes that have the validators property for details, e.g., oj.inputBase#validators.
  • when asyncValidators property changes. Not all EditableValue components have the asyncValidators property. See the sub-classes that have the asyncValidators property for details, e.g., oj.inputBase#async-validators.

Showing Deferred Messages

Deferred validation messages are displayed only when page author requests for it explicitly in one of the following ways:

Validators Participating in Deferred Validation

The required validator is the only validator type that participates in deferred validation. The required property needs to be set to true for the required validator to run.

User Assistance Text

User assistive text provides guidance to help the user understand what data to enter or select.

In the Redwood theme, by default all user assistance text shows inline. For input components, it shows when the field takes focus. In other components it shows all the time. See the user-assistance-density property for other ways the user assistance text can render, like in 'compact' mode, it will render as an icon on the label which when clicked will show the user assistance text in a notewindow.

The JET form component properties that are used for user assistance text are help.instruction, validator and converter hints, and help-hints. In the Redwood theme for clarity only one user assistance text shows to the user. The precedence rules are:

  • help.instruction shows;
  • if no help.instruction, then validator hint shows;
  • if no help.instruction or validator hint, then help-hints.definition shows;
  • if no help.instruction, validator hint, or help-hints.definition, then converter hint shows.
  • help-hints.source always shows along side the above.

In the Alta theme all the user assistance text are displayed to the user. By default help.instruction and the validator/converter hints show in a notewindow that is displayed when the field takes focus. The help-hints render as a help icon on the label and when clicked show in a notewindow. Note: If there is no label, help-hints help icon will not show.

Sometimes a validator or converter hints shows that you do not want. To not show it, set the display-options.validator-hint and/or display-options.converter-hint property to 'none'.

required and placeholder properties also can be used to guide the user. In Redwood, a required field shows the word Required under the field when the field is empty and does not have focus. Placeholder is shown when the field is empty and has focus.

Touch End User Information

Target Gesture Action
Input Tap Sets focus to input. Show user assistance text. This may be inline or in a notewindow depending upon theme and property settings.

Keyboard End User Information

Target Key Action
Input Tab In Set focus to the input. Show user assistance text. This may be inline or in a notewindow depending upon theme and property settings.

Accessibility

If not using the label-hint attribute, it is up to the application developer to associate an oj-label to the oj-input-text component. For accessibility, you should associate an oj-label element with the oj-input-text component by putting an id on the oj-input-text element, and then setting the for attribute on the oj-label to be the component's id.

The placeholder text is not read reliably by the screen reader. For accessibility reasons, you need to associate the text to its JET form component using aria-describedby.

Disabled content: JET supports an accessible luminosity contrast ratio, as specified in WCAG 2.0 - Section 1.4.3 "Contrast", in the themes that are accessible. (See the "Theming" chapter of the JET Developer Guide for more information on which themes are accessible.) Note that Section 1.4.3 says that text or images of text that are part of an inactive user interface component have no contrast requirement. Because disabled content may not meet the minimum contrast ratio required of enabled content, it cannot be used to convey meaningful information.

Label and InputText

If not using the label-hint attribute, it is up to the application developer to associate an oj-label with the oj-input-text component. For accessibility, you should associate an oj-label element to the oj-input-text component by putting an id on the oj-input-text element, and then setting the for attribute on the oj-label to be the component's id.

Note: Application logic should not interact with the component's properties or invoke its methods until the BusyContext indicates that the component is ready for interaction.

Styling Classes

.oj-form-control-full-width
Changes the max-width to 100% so that form components will occupy all the available horizontal space.
Example
<oj-input-text class="oj-form-control-full-width">
</oj-input-text>
.oj-text-field-start-end-icon
Use this class on a child div element if you want an icon to display in the start or end slot of an oj-input-text element.
Example
<oj-input-text id="myInputText" label-hint="My label">
  <div slot="start" :class="oj-text-field-start-end-icon oj-ux-ico-cc-card" role="img"><div>
</oj-input-text>

Category: Max Width

In the Redwood theme the default max width of a text field is 100%. These max width convenience classes are available to create a medium or small field.
The class is applied to the root element.

Classes:

.oj-form-control-max-width-sm
.oj-form-control-max-width-md

Example
<oj-input-text class="oj-form-control-max-width-md"></oj-input-text>

Category: Width

In the Redwood theme the default width of a text field is 100%. These width convenience classes are available to create a medium or small field.
The class is applied to the root element.

Classes:

.oj-form-control-width-sm
.oj-form-control-width-md

Example
<oj-input-text class="oj-form-control-width-md"></oj-input-text>

Category: Text Alignment

Classes that help align text of the element.

Classes:

.oj-form-control-text-align-right
.oj-form-control-text-align-start
.oj-form-control-text-align-end

Example
<oj-input-text class="oj-form-control-text-align-right">
</oj-input-text>

Slots

JET components that allow child content support slots. Please see the slots section of the JET component overview doc for more information on allowed slot content and slot types.

contextMenu

The contextMenu slot is set on the oj-menu within this element. This is used to designate the JET Menu that this component should launch as a context menu on right-click, Shift-F10, Press & Hold, or component-specific gesture. If specified, the browser's native context menu will be replaced by the JET Menu specified in this slot.

The application can register a listener for the Menu's ojBeforeOpen event. The listener can cancel the launch via event.preventDefault(), or it can customize the menu contents by editing the menu DOM directly, and then calling refresh() on the Menu.

To help determine whether it's appropriate to cancel the launch or customize the menu, the ojBeforeOpen listener can use component API's to determine which table cell, chart item, etc., is the target of the context menu. See the JSDoc of the individual components for details.

Keep in mind that any such logic must work whether the context menu was launched via right-click, Shift-F10, Press & Hold, or component-specific touch gesture.

end

The end slot is for adding html content after the input area, typically an oj-button or and icon. For example, a magnifying glass icon button for a search field can be provided in this slot.

Since:
  • 9.1.0
Example

Initialize the input text with child content specified for the end slot:

<oj-input-text>
  <oj-button slot="end" on-oj-action="[[performSearch]]" display="icons" >
    <img slot="endIcon" src="search.png">Search
   </oj-button>
</oj-input-text>

start

The start slot is for adding html content before the input area, typically an icon.

For example, an icon identifying the credit card type based on the value entered.

Since:
  • 9.1.0
Example

Initialize the input text with child content specified for the start slot:

<oj-input-text on-raw-value-changed="[[changeCreditCardTypeIcon]]">
  <img slot="start" :src="[[creditCardTypeIcon]]">
</oj-input-text>

Attributes

async-validators :Array.<oj.AsyncValidator.<V>>

List of asynchronous validators used by the component when performing validation. Use async-validators when you need to perform some validation work on the server. Otherwise, use validators, which are synchronous.

Each item in the Array is an instance that duck types oj.AsyncValidator. Implicit validators created by a component when certain attributes are present (e.g. required attribute) are separate from validators specified through the async-validators attribute and the validators attribute. At runtime when the component runs validation, it combines the implicit validators with the list specified through the validators attribute and also the list specified through the async-validators attribute. Error messages are shown as soon as each async validator returns; we do not wait until all the async validators finish to show errors. If the component's valid state changes for the worse, it is also updated as each validator returns so valid will be invalidShown as soon as the first validator has an Error.

It is recommended that you show the value you are validating in the error message because if the async operation takes a while, the user could be typing in a new value when the error message comes back and might be confused what value the error is for. However, if the user enters a new value (like presses Enter or Tab), a new validation lifecycle will start and validation errors for the previous value will not be shown to the user. If you need to format the value for the error message, you can use e.g. for number new NumberConverter.IntlNumberConverter(converterOption) to get the converter instance, then call converter.format(value).

Hints exposed by async-validators and validators are shown in the notewindow by default, or as determined by the 'validatorHint' property set on the display-options attribute.

Since async validators are run asynchronously, you should wait on the BusyContext before you check valid property or the value property. Alternatively you can add a callback to the validChanged or valueChanged events.

The steps performed always, running validation and clearing messages is the same as for the oj.inputBase#validators attribute.

autocomplete :('on'|'off'|string)

Dictates component's autocomplete state. This attribute indicates whether the value of the control can be automatically completed by the browser. The common values are "on" and "off".

Since this attribute passes through to the input element unchanged, you can look at the html specs for detailed information for how browsers behave and what values besides "on" and "off" you can set. The html spec says the default is "on", so when autocomplete is not explicitly set, the browsers treat it as "on".

converter :(Promise.<oj.Converter.<V>>|oj.Converter.<V>|oj.Validation.RegisteredConverter|null) converter :(Promise.<oj.Converter.<V>>|oj.Converter.<V>|null)

A converter instance or Promise to a converter instance or one that duck types oj.Converter.

When converter property changes due to programmatic intervention, the element performs various tasks based on the current state it is in.

Steps Performed Always

  • Any cached converter instance is cleared and new converter created. The converter hint is pushed to messaging. E.g., notewindow displays the new hint(s).

Running Validation

  • if element is valid when converter property changes, the display value is refreshed.
  • if element is invalid and is showing messages when converter property changes then all element messages are cleared and full validation run using the current display value on the element.
    • if there are validation errors, then value property is not updated, and the error is shown. The display value is not refreshed in this case.
    • if no errors result from the validation, the value property is updated; page author can listen to the valueChanged event to clear custom errors. The display value is refreshed with the formatted value provided by converter.
  • if element is invalid and has deferred messages when converter property changes, the display value is again refreshed with the formatted value provided by converter.

Clearing Messages

  • Only messages created by the element are cleared.
  • messagesCustom property is not cleared. Page authors can choose to clear it explicitly when setting the converter option.

The hint exposed by the converter is shown inline by default in the Redwood theme when the field has focus. In the Alta theme, converter hints are shown in a notewindow on focus, or as determined by the 'converterHint' property set on the display-options attribute. In either theme, you can turn off showing converter hints by using the 'converterHint' property set to 'none' on the display-options attribute.

In the Redwood theme, only one hint shows at a time, so the precedence rules are: help.instruction shows; if no help.instruction then validator hints show; if none, then help-hints.definition shows; if none, then converter hint shows. help-hints.source always shows along with the other help or hint.

Deprecated:
Since Value Description
8.0.0 oj.Validation.RegisteredConverter Defining a converter with an object literal with converter type and its options (aka JSON format) has been deprecated and does nothing.

disabled :boolean

Whether the component is disabled. The default is false.

When the disabled property changes due to programmatic intervention, the component may clear messages and run validation in some cases.

  • when a required component is initialized as disabled value="{{currentValue}}" required disabled, deferred validation is skipped.
  • when a disabled component is enabled,
    • if component is invalid and showing messages then all component messages are cleared, and full validation run using the display value.
      • if there are validation errors, they are shown.
      • if no errors result from the validation, the value property is updated. Page authors can listen to the valueChanged event to clear custom errors.
    • if component is valid and has no errors then deferred validation is run.
      • if there is a deferred validation error, then the valid property is updated.
    • if component is invalid and deferred errors then component messages are cleared and deferred validation re-run.
      • if there is a deferred validation error, then the valid property is updated.
  • when enabled component is disabled then no validation is run and the component appears disabled.

display-options :Object

Display options for auxiliary content that determines whether or not it should be displayed.

The sub-properties of the display-options configure aspects of visual behavior such as where types of information is shown. The values of these sub-properties are specified either as an array of strings or a string. When an array is specified the first display option takes precedence over the second display option and so on.

When display-options changes due to programmatic intervention, the component updates its display to reflect the updated choices. For example, if you don't want to show the converter hint, set the display-options.converter-hint to 'none'.

A side note: help.instruction and message detail text can include formatted HTML text, whereas hints and message summary text cannot. If you use formatted text, it should be accessible and make sense to the user if formatting wasn't there. To format the help.instruction, you could do this:

<html>Enter <b>at least</b> 6 characters</html>

help.instruction :string

A type of user assistance text. User assistance text is used to provide guidance to help the user understand what data to enter or select.

In the Redwood theme for clarity only one user assistance text shows to the user. The precedence rules are:

  • help.instruction shows;
  • if no help.instruction, then validator hint shows;
  • if no help.instruction or validator hint, then help-hints.definition shows;
  • if no help.instruction, validator hint, or help-hints.definition, then converter hint shows.
  • help-hints.source always shows along side the above.

In the Redwood theme, by default all user assistance text shows inline. For input components, it shows when the field takes focus. In other components it shows all the time. See the user-assistance-density property for other ways the user assistance text can render.

In Alta theme, help.instruction displays in a notewindow when the field takes focus. How is help.instruction better than the html 'title' attribute? The html 'title' attribute only shows up as a tooltip on mouse over, not on keyboard and not in a mobile device. So the html 'title' would only be for text that is not important enough to show all users, or for text that you show the users in another way as well, like in the label. Also you cannot theme the native browser's title window like you can the JET notewindow, so low vision users may have a hard time seeing the 'title' window. For these reasons, the JET EditableValue components do not use the HTML's 'title' attribute and instead use the help.instruction attribute.

To include formatted text in the help.instruction, format the string using html tags. For example the help.instruction might look like:

<oj-some-element help.instruction="<html>Enter <b>at least</b> 6 characters</html>"></oj-some-element>
If you use formatted text, it should be accessible and make sense to the user if formatting wasn't there.

In the Alta theme, the help-hints.source will show as a a help icon next to the label. When clicked the page will navigate to the source url.

For security reasons we only support urls with protocol 'http:' or 'https:'. If the url doesn't comply we ignore it and throw an error. Pass in an encoded URL since we do not encode the URL.

label-edge :('inside'|'none'|'provided')

Specifies how the label of the component is created when the label-hint attribute is set on the component.

The default value varies by theme, and it works well for the theme in most cases. If the component is in an oj-form-layout, and the label-edge attribute on oj-form-layout is set to an explicit value, the label-edge attribute on all form controls should also be set to an explict value. For example, if the label-edge attribute on oj-form-layout is set to "start" or "top", the label-edge attribute of all form controls should be set to "provided".

Supported Values:
Value Description
inside The component creates the label using the label-hint attribute.

For text input components (such as oj-input-text), the label floats over the input element but moves up on focus or when the component has a value.

For non-text input components (such as oj-checkboxset), the label is created at the top of the component and doesn't move.

none The component will not have a label, regardless of whether it's in an oj-form-layout or not.

If the component has a label-hint attribute but no labelled-by, aria-label, or aria-labelledby attribute, the label-hint value will be used as the aria-label.

Note that if the component already has an external label, "none" should not be specified and "provided" should be used instead. Otherwise it may end up with conflicting label information.

provided Label is provided by the parent if the parent is an oj-form-layout.

oj-form-layout provides the label using the label-hint from the form control and the label-edge from oj-form-layout.

If there is no oj-form-layout, use an oj-label.

When label-edge is "provided", it gives a hint to oj-form-layout parent element to create an oj-label element for the component. When the label-hint attribute changes, oj-form-layout element refreshes to display the updated label information.

When label-edge is "inside", it gives a hint to the component itself to render a label.

When label-edge is "none", and if the component has no labelled-by, aria-label, or aria-labelledby attribute, the label-hint value will be used as the aria-label.

labelled-by :string|null

The oj-label sets the labelledBy property programmatically on the form component to make it easy for the form component to find its oj-label component (a document.getElementById call.)

The application developer should use the 'for'/'id api to link the oj-label with the form component; the 'for' on the oj-label to point to the 'id' on the input form component. This is the most performant way for the oj-label to find its form component.

messages-custom :Array.<oj.Message>

List of messages an app would add to the component when it has business/custom validation errors that it wants the component to show. This allows the app to perform further validation before sending data to the server. When this option is set the message shows to the user right away. To clear the custom message, set messagesCustom back to an empty array.

Each message in the array is an object that duck types oj.Message. See oj.Message for details.

See the Validation and Messages section for details on when the component clears messagesCustom; for example, when full validation is run.

In the Redwood theme, the Message summary is not displayed to the user, so make sure to have a Message detail set in your Message object.

(readonly) raw-value :RV

The rawValue is the read-only property for retrieving the current value from the input field in string form. The main consumer of rawValue is a converter.

The rawValue updates on the 'input' javascript event, so the rawValue changes as the value of the input is changed. If the user types in '1,200' into the field, the rawValue will be '1', then '1,', then '1,2', ..., and finally '1,200'. Then when the user blurs or presses Enter the value property gets converted and validated (if there is a converter or validators) and then gets updated if valid.

This is a read-only attribute so page authors cannot set or change it directly.

  • true

readonly :boolean

Whether the component is readonly. The readonly property sets or returns whether an element is readonly, or not. A readonly element cannot be modified. However, a user can tab to it, highlight it, focus on it, and copy the text from it. If you want to prevent the user from interacting with the element, use the disabled property instead.

The default value for readonly is false. However, if the form component is a descendent of oj-form-layout, the default value for readonly could come from the oj-form-layout component's readonly attribute. The oj-form-layout uses the MetadataTypes.PropertyBinding provide property to provide its readonly attribute value to be consumed by descendent components. The form components are configured to consume the readonly property if an ancestor provides it and it is not explicitly set. For example, if the oj-form-layout's readonly attribute is set to true, and a descendent form component does not have its readonly attribute set, the form component's readonly will be true.

required :boolean

Whether the component is required or optional. When required is set to true, an implicit required validator is created using the RequiredValidator - new RequiredValidator(). Translations specified using the translations.required attribute and the label associated with the component, are passed through to the options parameter of the createValidator method.

When required property changes due to programmatic intervention, the component may clear messages and run validation, based on the current state it's in.

Running Validation

  • if component is valid when required is set to true, then it runs deferred validation on the value property. This is to ensure errors are not flagged unnecessarily.
  • if component is invalid and has deferred messages when required is set to false, then component messages are cleared but no deferred validation is run.
  • if component is invalid and currently showing invalid messages when required is set, then component messages are cleared and normal validation is run using the current display value.
    • if there are validation errors, then value property is not updated and the error is shown.
    • if no errors result from the validation, the value property is updated; page author can listen to the valueChanged event on the component to clear custom errors.

Clearing Messages

  • Only messages created by the component are cleared.
  • messagesCustom property is not cleared.

This property set to false implies that a value is not required to be provided by the user. This is the default. This property set to true implies that a value is required to be provided by the user.

Additionally a required validator - oj.RequiredValidator - is implicitly used if no explicit required validator is set. An explicit required validator can be set by page authors using the validators attribute.

In the Alta theme the input's label will render a required icon. In the Redwood theme, by default, a Required text is rendered inline when the field is empty. If user-assistance-density is 'compact', it will show on the label as an icon.

user-assistance-density :('reflow'|'efficient'|'compact')

Note: This attribute is not supported in the following themes: Alta

Specifies the density of the form component's user assistance presentation. It can be shown inline with reserved rows to prevent reflow if a user assistance text shows up, inline without reserved rows that would reflow if a user assistance text shows up, or it can be shown compactly in a popup instead.

The default value is 'reflow' when the form component is not a descendent of an oj-form-layout component. When the form component is a descendent of an oj-form-layout, the default value comes from the oj-form-layout's user-assistance-density attribute value.

The oj-form-layout component uses the MetadataTypes.PropertyBinding provide property to provide its user-assistance-density attribute value to be consumed by descendent components. The form components are configured to consume the user-assistance-density property if an ancestor provides it and it is not explicitly set on the form component. Example, oj-form-layout defaults user-assistance-density='efficient', so all its form components descendents will have user-assistance-density='efficient' by default.

Supported Values:
Value Description
compact Messages, help, hints, and required will not be shown inline; they will show in a mode that keeps the screen more compact, like a popup for the messages, and a required icon to indicate Required.
efficient Messages, help, hints, and required are all shown inline under the field with reserved space.

(readonly) valid :valid|pending|invalidHidden|invalidShown

The current valid state of the component. It is evaluated on initial render. It is re-evaluated

  • after each validator (validators or async-validators) is run (full or deferred)
  • when messagesCustom is updated, since messagesCustom can be added by the app developer any time.
  • when showMessages() is called. Since showMessages() moves the hidden messages into messages shown, if the valid state was "invalidHidden" then it would become "invalidShown".
  • when the required property has changed. If a component is empty and has required set, the valid state may be "invalidHidden" (if no invalid messages are being shown as well). If required property is removed, the valid state would change to "valid".

Note: New valid states may be added to the list of valid values in future releases. Any new values will start with "invalid" if it is an invalid state, "pending" if it is pending state, and "valid" if it is a valid state.

Supported Values:
Value Description
invalidHidden The component has invalid messages hidden and no invalid messages showing. An invalid message is one with severity "error" or higher.
invalidShown The component has invalid messages showing. An invalid message is one with severity "error" or higher.
pending The component is waiting for the validation state to be determined. The "pending" state is set at the start of the convert/validate process.

validators :(Array.<(oj.Validator.<V>|oj.AsyncValidator.<V>|oj.Validation.RegisteredValidator)>|null) validators :(Array.<(oj.Validator.<V>|oj.AsyncValidator.<V>)>|null)

List of validators, synchronous or asynchronous, used by component along with asynchronous validators from the deprecated async-validators option and the implicit component validators when performing validation. Each item is either an instance that duck types oj.Validator or oj.AsyncValidator.

Implicit validators are created by the element when certain attributes are present. For example, if the required attribute is set, an implicit oj.RequiredValidator is created. At runtime when the component runs validation, it combines all the implicit validators with all the validators specified through this validators attribute and the async-validators attribute, and runs all of them.

Hints exposed by validators are shown inline by default in the Redwood theme when the field has focus. In the Alta theme, validator hints are shown in a notewindow on focus, or as determined by the 'validatorHint' property set on the display-options attribute.

In the Redwood theme, only one hint shows at a time, so the precedence rules are: help.instruction shows; if no help.instruction then validator hints show; if none, then help-hints.definition shows; if none, then converter hint shows. help-hints.source always shows along with the other help or hint.

When validators property changes due to programmatic intervention, the component may decide to clear messages and run validation, based on the current state it is in.

Steps Performed Always

  • The cached list of validator instances are cleared and new validator hints is pushed to messaging. E.g., notewindow displays the new hint(s).

Running Validation

  • if component is valid when validators changes, component does nothing other than the steps it always performs.
  • if component is invalid and is showing messages when validators or async-validators changes then all component messages are cleared and full validation run using the display value on the component.
    • if there are validation errors, then value property is not updated and the error is shown.
    • if no errors result from the validation, the value property is updated; page author can listen to the valueChanged event to clear custom errors.
  • if component is invalid and has deferred messages when validators changes, it does nothing other than the steps it performs always.

Clearing Messages

  • Only messages created by the component are cleared.
  • messagesCustom property is not cleared.

virtual-keyboard :auto|email|number|search|tel|text|url

The type of virtual keyboard to display for entering a value on mobile browsers. This attribute has no effect on desktop browsers.

When setting the virual keyboard to "number", if the converter on the component formats the value with non-numeric characters the value will not display. If applications want to use a "number" virtual keyboard they need to provide a converter that doesn't format with non-numeric characters.

Supported Values:
Value Description
auto The component will determine the best virtual keyboard to use.
email Use a virtual keyboard for entering email addresses.
number Use a virtual keyboard for entering numbers.

Note that on Android and Windows Mobile, the "number" keyboard does not contain the minus sign. This value should not be used on fields that accept negative values.

Events

ojAnimateEnd

Triggered when a default animation has ended.
Properties:

All of the event payloads listed below can be found under event.detail. See Events and Listeners for additional information.

Name Type Description
action string The action that triggered the animation.

Supported values are:
  • "inline-open" - when an inline message container opens or increases in size
  • "inline-close" - when an inline message container closes or decreases in size
  • "notewindow-open" - when a note window opens
  • "notewindow-close" - when a note window closes
element Element The element being animated.
Since:
  • 4.0.0

ojAnimateStart

Triggered when a default animation is about to start on an element owned by the component.

The default animation can be cancelled by calling event.preventDefault, followed by a call to event.detail.endCallback. event.detail.endCallback should be called immediately after event.preventDefault if the application merely wants to cancel animation, or it should be called when the custom animation ends if the application is invoking another animation function. Failure to call event.detail.endCallback may prevent the component from working properly.

For more information on customizing animations, see the documentation of oj.AnimationUtils.

The default animations are controlled via the theme (SCSS) :

// default animations for "notewindow" display option
$popupTailOpenAnimation: (effect: "zoomIn", transformOrigin: "#myPosition") !default;
$popupTailCloseAnimation: (effect: "none") !default;

// default animations for "inline" display option
$messageComponentInlineOpenAnimation: (effect: "expand", startMaxHeight: "#oldHeight") !default;
$messageComponentInlineCloseAnimation: (effect: "collapse", endMaxHeight: "#newHeight") !default;
Properties:

All of the event payloads listed below can be found under event.detail. See Events and Listeners for additional information.

Name Type Description
action string The action that triggers the animation.

Supported values are:
  • "inline-open" - when an inline message container opens or increases in size
  • "inline-close" - when an inline message container closes or decreases in size
  • "notewindow-open" - when a note window opens
  • "notewindow-close" - when a note window closes
element Element The element being animated.
endCallback function():void If the event listener calls event.preventDefault to cancel the default animation, it must call the endCallback function when it finishes its own animation handling and any custom animation has ended.

If there were no deferred messages this method simply returns.

Since:
  • 0.7.0
Returns:
Type
void

validate : {Promise<'valid'|'invalid'>}

Validates the component's display value using the converter and all validators registered on the component and updates the value option by performing the following steps.

  1. All messages are cleared, including custom messages added by the app.
  2. If no converter is present then processing continues to next step. If a converter is present, the UI value is first converted (i.e., parsed). If there is a parse error then the messages are shown.
  3. If there are no validators setup for the component the value option is updated using the display value. Otherwise all validators are run in sequence using the parsed value from the previous step. The implicit required validator is run first if the component is marked required. When a validation error is encountered it is remembered and the next validator in the sequence is run.
  4. At the end of validation if there are errors, the messages are shown. If there were no errors, then the value option is updated.
Since:
  • 4.0.0
Returns:
Promise resolves to "valid" if there were no converter parse errors and the component passed all validations. The Promise resolves to "invalid" if there were converter parse errors or if there were validation errors.
Type
Promise<'valid'|'invalid'>
