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.

-
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 thevalueChanged
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.
- if component is invalid and showing messages then all component messages are cleared,
and full validation run using the display value.
- when enabled component is disabled then no validation is run and the component appears disabled.

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

-
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. help-hints could come from a help system.
In the Redwood theme for clarity only one user assistance text shows to the user. The precedence rules are:
- help.instruction shows;

In the Alta theme the help-hint.definition shows up when the user hovers over the help icon on the label, 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.

In the Redwood theme, the help-hints.source will show as a link inline to the field. For input components, it shows when the field takes focus. For other components, it shows all the time.
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".
- Since:
- 8.0.0
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.

-
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.

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.

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.

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 itsuser-assistance-density
attribute value to be consumed by descendent components. The form components are configured to consume theuser-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.- Default Value:
"reflow"
- Since:
- 9.0.0
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. reflow
Messages, help, hints, and required are all shown inline under the field with no reserved space. Names

-
(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.
- Supports writeback:

.event.detail.endCallback
should be called immediately afterevent.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 callevent.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;

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 thevalueChanged
event to clear custom errors.
- if there are validation errors, then
- 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}

- 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.

-
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

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
- component always runs deferred validation; the
