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.

The oj-switch component enhances input element and manages the selection of Boolean values.

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.

Touch End User Information

Target Gesture Action
Switch Thumb Tap Toggle switch value

Keyboard End User Information

Target Key Action
Switch Thumb Enter or Space Toggle switch value
Switch Thumb Tab In Set focus to the thumb. If hints, title or messages exist in a notewindow, pop up the notewindow.

Disabled items can not receive keyboard focus.

Accessibility

The component is accessible; it sets and maintains the appropriate aria- attributes, like aria-checked and aria-disabled.

It is up to the application developer to associate the label to the input element. For Switch, you should put an id on the input element, and then set the for attribute on the label to be the input's id.

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.

See also the oj-focus-highlight discussion.

Styling

The following CSS classes can be applied by the page author as needed.

Class Description
oj-switch Top level switch class.
oj-focus-highlight Under normal circumstances this class is applied automatically. It is documented here for the rare cases that an app developer needs per-instance control.

The oj-focus-highlight class applies focus styling that may not be desirable when the focus results from pointer interaction (touch or mouse), but which is needed for accessibility when the focus occurs by a non-pointer mechanism, for example keyboard or initial page load.

The application-level behavior for this component is controlled in the theme by the $focusHighlightPolicy SASS variable; however, note that this same variable controls the focus highlight policy of many components and patterns. The values for the variable are:

  • nonPointer: oj-focus-highlight is applied only when focus is not the result of pointer interaction. Most themes default to this value.
  • all: oj-focus-highlight is applied regardless of the focus mechanism.
  • none: oj-focus-highlight is never applied. This behavior is not accessible, and is intended for use when the application wishes to use its own event listener to precisely control when the class is applied (see below). The application must ensure the accessibility of the result.

To change the behavior on a per-instance basis, the application can set the SASS variable as desired and then use event listeners to toggle this class as needed.

Label and Switch

For accessibility, you should associate a label element with the input by putting an id on the input, and then setting the for attribute on the label to be the input's id.

Setting the Value Attribute

The value attribute should be Boolean. If the value attribute is undefined, then it is false.

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.

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.

Attributes

(nullable) described-by :string

The oj-label sets the described-by attribute programmatically on the form component. This attribute is not meant to be set by an application developer directly. The described-by is copied to the aria-describedby attribute on the component's inner dom element, and it is needed for accessibility.

Property disabled
Property change event disabledChanged
Property change listener attribute (must be of type function, see Events and Listeners for additional information.) on-disabled-changed

display-options :Object

Display options for auxiliary content that determines where it should be displayed in relation to the component.

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 'help.instruction' property goes from 'notewindow' to 'none' then it no longer shows in the notewindow.

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>

Property help

Property change listener attribute (must be of type function, see Events and Listeners for additional information.) on-help-changed

help.instruction :string

Represents advisory information for the component, such as would be appropriate for a tooltip.

When help.instruction is present it is by default displayed in the notewindow, or as determined by the 'helpInstruction' property set on the displayOptions attribute. When the help.instruction property changes the component refreshes to display the updated information.

JET takes the help instruction text and creates a notewindow with the text. The notewindow pops up when the field takes focus and closes when the field loses 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.

help-hints :Object

Represents hints to render help information on the label of the editable component. This is used when an oj-form-layout creates labels for its editable value component children. Also when an editable value component (inside or outside oj-form-layout) creates a label for itself (if you set labelEdge), these hints will be used to render the help information. However, please note that, help information will not be rendered if the label is created inside the input field (labelEdge ='inside').

This is used only if the editable component is added as a direct child to an oj-form-layout element, and the labelHint property is also specified.

The helpHints object contains a definition property and a source property.

  • definition - hint for help definition text.
  • source - hint for help source URL.

It is what shows up when the user hovers over the help icon, or tabs into the help icon, or press and holds the help icon on a mobile device. No formatted text is available for help definition attribute.

See the help-hints attribute for usage examples.

(nullable) help-hints.source :string

Hint for help source URL associated with the label.

If present, a help icon will render next to the label. 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.

The help-hints attribute will be ignored. No help related information will be rendered on the label.
"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.

label-hint :string

Represents a hint for rendering a label on the component.

This is used in combination with the label-edge attribute to control how the label should be rendered.

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.

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 element's readOnly property is used as its initial value if it exists, when the attribute is not explicitly set. When neither is set, readOnly defaults to false.

translations :object|null

A collection of translated resources from the translation bundle, or null if this component has no resources. Resources may be accessed and overridden individually or collectively, as seen in the examples.

If the component does not contain any translatable resource, the default value of this attribute will be null. If not, an object containing all resources relevant to the component.

If this component has translations, their documentation immediately follows this doc entry.

(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.

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 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.
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.

Methods

getProperty(property) : {any}

Retrieves the value of a property or a subproperty. The return type will be the same as the type of the property as specified in this API document. If the method is invoked with an incorrect property/subproperty name, it returns undefined.
Parameters:
Name Type Description
property string The property name to get. Supports dot notation for subproperty access.
Since:
  • 4.0.0
Returns:
Type
any
Example

Get a single subproperty of a complex property:

let subpropValue = myComponent.getProperty('complexProperty.subProperty1.subProperty2');

refresh() : {void}

Called when the DOM underneath the component changes requiring a re-render of the component. An example is when the id for the input changes.

Another time when refresh might be called is when the locale for the page changes. When it changes, attributes used by its converter and validator that are locale specific, its hints, messages and translations will be updated.

When refresh method is called, the component may take various steps such as clearing messages, running validation etc., based on the state it is in.

Steps Performed Always

  • The converter and validators used by the component are reset, and new converter and validator hints is pushed to messaging. E.g., notewindow displays the new hint(s).

Running Validation

  • if component is valid when refresh() is called, the display value is refreshed if component has a converter set.
  • if component is invalid and is showing messages when refresh() is called, then all component messages are cleared and full validation run using the display value on the component.
    • if there are validation errors, then value attribute is not updated and the error is shown.
    • if no errors result from the validation, the value attribute is updated; page author can listen to the valueChanged event to clear custom errors.
  • if component is invalid and has deferred messages when refresh() is called, then all component messages are cleared and deferred validation is run.

Clearing Messages

  • If clearing messages only those created by the component are cleared.
  • messagesCustom attribute is not cleared.

Since:
  • 0.7.0
Returns:
Type
void

reset() : {void}

Resets the component by clearing all messages and messages attributes - messagesCustom - and updates the component's display value using the attribute value. User entered values will be erased when this method is called.
Since:
  • 0.7.0
Returns:
Type
void

setProperties(properties) : {void}

Performs a batch set of properties. The type of value for each property being set must match the type of the property as specified in this API document.
Parameters:
Name Type Description
properties Object An object containing the property and value pairs to set.
Since:
  • 4.0.0
Returns:
Type
void
Example

Set a batch of properties:

myComponent.setProperties({"prop1": "value1", "prop2.subprop": "value2", "prop3": "value3"});

setProperty(property, value) : {void}

Sets a property or a subproperty (of a complex property) and notifies the component of the change, triggering a [property]Changed event. The value should be of the same type as the type of the attribute mentioned in this API document.
Parameters:
Name Type Description
property string The property name to set. Supports dot notation for subproperty access.
value any The new value to set the property to.
Since:
  • 4.0.0
Returns:
Type
void
Example

Set a single subproperty of a complex property:

myComponent.setProperty('complexProperty.subProperty1.subProperty2', "someValue");

showMessages() : {void}

Takes all deferred messages and shows them. It then updates the valid property; e.g., if the valid state was "invalidHidden" before showMessages(), the valid state will become "invalidShown" after showMessages().

If there were no deferred messages this method simply returns.

Since:
  • 0.7.0
Returns:
Type
void
