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 elements can have up to two types of child content:
- Any child element with a
slotattribute will be moved into that named slot, e.g.<span slot='startIcon'>...</span>. All supported named slots are documented below. Child elements with unsupported named slots will be removed from the DOM. - Any child element lacking a
slotattribute will be moved to the default slot, also known as a regular child. This is documented under the "Default" heading below.
-
Default
-
The <oj-combobox-many> element accepts
oj-options as children. See the oj-option doc for details about accepted children and slots.Example
Initialize the Combobox with child content specified:
<oj-combobox-many> <oj-option value="option1">Option1</oj-option> </oj-combobox-many> -
contextMenu
-
The contextMenu slot is set on the
oj-menuwithin 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 and demos 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.
Example
Initialize the component with a context menu:
<oj-some-element> <-- use the contextMenu slot to designate this as the context menu for this component --> <oj-menu slot="contextMenu" style="display:none" aria-label="Some element's context menu"> ... </oj-menu> </oj-some-element>
Attributes
-
async-validators :Array.<oj.AsyncValidator.<V>>
-
List of asynchronous validators used by the component when performing validation. Use
async-validatorswhen you need to perform some validation work on the server. Otherwise, usevalidators, 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.
requiredattribute) are separate from validators specified through theasync-validatorsattribute and thevalidatorsattribute. At runtime when the component runs validation, it combines the implicit validators with the list specified through thevalidatorsattribute and also the list specified through theasync-validatorsattribute. 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
oj.IntlConverterUtils.getConverterInstance(converterOption)to get the converter instance, then callconverter.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-optionsattribute.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 onValidChanged or ojValueChanged events.
The steps performed always, running validation and clearing messages is the same as for the
validatorsattribute.

converter :(oj.Converter.<any>|oj.Validation.RegisteredConverter)
-
A converter instance that duck types oj.Converter. Or an object literal containing the following properties.
When
converterproperty 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
converterproperty changes, the display value is refreshed. - if element is invalid and is showing messages when
converterproperty changes, then all messages generated by the element are cleared and full validation run using its current display value.- if there are validation errors, then
valueproperty is not updated, and the errors are shown. The display value is not refreshed in this case. - if no errors result from the validation,
valueproperty is updated; page author can listen to thevalueChangedevent on thevalueproperty to clear custom errors. The display value is refreshed with the formatted value provided by converter.
- if there are validation errors, then
- if element is invalid and has deferred messages when
converterproperty changes, then the display value is refreshed with the formatted value provided by converter.
Clearing Messages
- When element messages are cleared in the cases described above, messages created by the element are cleared.
messages-customproperty is not cleared. Page authors can choose to clear it explicitly when setting the converter property.

It is used to establish a relationship between this component and another element. Typically this is not used by the application developer, but by the oj-label custom element's code. One use case is where the oj-label custom element code writes described-by on its form component for accessibility reasons. To facilitate correct screen reader behavior, the described-by attribute is copied to the aria-describedby attribute on the component's dom element.

- 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.

display-options :Object
-
Display options for auxilliary content that determines where it should be displayed in relation to the component.
The types of messaging content for which display options can be configured include
converterHint,helpInstruction,messages, andvalidatorHint.
The display options for each type is specified either as an array of strings or a string. When an array is specified the first display option takes precedence over the second 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:

Item Name Property helpProperty change event helpChangedProperty change listener attribute (must be of type function) 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
displayOptionsattribute. When thehelp.instructionproperty changes the component refreshes to display the updated information.JET takes the help instruction text and creates a notewindow with the text. The help instruction only shows up as a tooltip on mouse over, not on keyboard and not in a mobile device. So help instruction 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 it. For these reasons, the JET EditableValue components do not use the HTML's title 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>- Default Value:

PREVIEW: This is a preview API. Preview APIs are production quality, but can be changed on a major version without a deprecation path.
-
The current valid state of the component. It is evaluated on initial render. It is re-evaluated
- after validation 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.

validators :(Array.<(oj.Validator.<V>|oj.Validation.RegisteredValidator)>|null)
-
List of synchronous validators used by component along with asynchronous validators and the implicit component validators when performing validation. Each item is either an instance that duck types oj.Validator, or is an Object literal containing the properties listed below.
Implicit validators are created by the element when certain attributes are present. For example, if the
requiredattribute 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 thisvalidatorsattribute and theasync-validatorsattribute, and runs all of them.Hints exposed by validators are shown in the notewindow by default, or as determined by the 'validatorHint' property set on the
display-optionsattribute.When
validatorsproperty changes due to programmatic intervention, the element 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 element is valid when validators changes, element does nothing other than the steps it always performs.
- if element is invalid and is showing messages -
messages-shownproperty is non-empty, whenvalidatorsorasync-validators - if there are validation errors, then
valueproperty is not updated and the error is shown. - if no errors result from the validation, the
valueproperty is updated; page author can listen to thevalueChangedevent on thevalueproperty to clear custom errors.
- if element 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 element are cleared.
messages-customproperty is not cleared.

Events
-
ojAnimateEnd
-
Triggered when a default animation has ended.
- "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
- Since:
- 4.0.0
Properties:
All of the event payloads listed below can be found under
event.detail.Name Type Description actionstring The action that triggers the animation. Supported values are: elementElement The element being animated. Examples
Define an event listener for the
ojAnimateEndevent to add any processing after the end of "inline-open" animation:var listener = function( event ) { // Check if this is the end of "inline-open" animation for inline message if (event.detail.action == "inline-open") { // Add any processing here } };Specify an
ojAnimateEndlistener via the DOM attribute:<oj-combobox-many on-oj-animate-end='[[listener]]'></oj-combobox-many>Specify an
ojAnimateEndlistener via the JavaScript property:myComboboxMany.onOjAnimateEnd = listener;Add an
ojAnimateEndlistener via theaddEventListenerAPI:myComboboxMany.addEventListener('ojAnimateEnd', listener); -
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 toevent.detail.endCallback.event.detail.endCallbackshould be called immediately afterevent.preventDefaultif 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.endCallbackmay 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 $noteWindowOpenAnimation: (effect: "zoomIn", transformOrigin: "#myPosition") !default; $noteWindowCloseAnimation: (effect: "none") !default; // default animations for "inline" display option $messageComponentInlineOpenAnimation: (effect: "expand", startMaxHeight: "#oldHeight") !default; $messageComponentInlineCloseAnimation: (effect: "collapse", endMaxHeight: "#newHeight") !default;- "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
- Since:
- 4.0.0
Properties:
All of the event payloads listed below can be found under
event.detail.Name Type Description actionstring The action that triggers the animation. Supported values are: elementElement The element being animated. endCallbackfunction():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. Examples
Define an event listener for the
ojAnimateStartevent to override the default "inline-open" animation:var listener = function( event ) { // Change the "inline-open" animation for inline message if (event.detail.action == "inline-open") { // Cancel default animation event.preventDefault(); // Invoke new animation and call endCallback when the animation ends oj.AnimationUtils.fadeIn(event.detail.element).then(event.detail.endCallback); } };Define an event listener for the
ojAnimateStartevent to cancel the default "notewindow-close" animation:var listener = function( event ) { // Change the "notewindow-close" animation for note window if (ui.action == "notewindow-close") { // Cancel default animation event.preventDefault(); // Call endCallback immediately to indicate no more animation event.detail.endCallback(); };Specify an

Methods
-
getProperty(property) → {any}
-
Retrieves a value for a property or a single subproperty for complex properties.
Parameters:
Name Type Description propertystring 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:
var subpropValue = myComponent.getProperty('complexProperty.subProperty1.subProperty2'); -
refresh()
-
Refreshes the combobox.
This method does not accept any arguments.
-
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
Returns:
- Type
- void
Example
Reset component
myComp.reset(); -
setProperties(properties) → {void}
-
Performs a batch set of properties.
Parameters:
Name Type Description propertiesObject 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 single subproperty for complex properties and notifies the component of the change, triggering a [property]Changed event.
Parameters:
Name Type Description propertystring The property name to set. Supports dot notation for subproperty access. valueany 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
Returns:
- Type
- void
Example
Display all messages including deferred ones.
myComp.showMessages(); -
validate() → {Promise}
PREVIEW: This is a preview API. Preview APIs are production quality, but can be changed on a major version without a deprecation path.
-
- All messages are cleared, including custom messages added by the app.
- 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.
- If there are no validators setup for the component the
valueoption 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. - At the end of validation if there are errors, the messages are shown.
If there were no errors, then the
valueoption is updated.
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
Examples
Validate component using its current value.
myComp.validate();Validate component and use the Promise's resolved state.
myComp.validate().then( function(result) { if(result === "valid") { submitForm(); } });
