JET Checkboxset

The JET oj-checkboxset component manages a set of oj-option child elements and creates the necessary dom elements for the actual checkboxes.

To use an oj-checkboxset, add one or more oj-option child elements for each checkbox desired. Note, if you add or remove an oj-option after the oj-checkboxset is rendered, you should call refresh() on the oj-checkboxset. Note, oj-optgroup is not a supported child element of oj-checkboxset.

The child content can be configured via inline HTML content or a DataProvider. It is recommended that inline HTML content should only be used for static data and the DataProvider should always be used for mutable data.

A JET Checkbox Set can be created with the following markup.


<oj-checkboxset>
  <oj-option value="option 1">option 1</oj-option>
  <oj-option value="option 2">option 2</oj-option>
  <oj-option value="option 3">option 3</oj-option>
  <oj-option value="option 4">option 4</oj-option>
</oj-checkboxset>

A JET Checkbox Set can be created with a DataProvider.


<oj-checkboxset options="[[dataprovider]]">
</oj-checkboxset>

You can enable and disable an oj-checkboxset, which will enable and disable all contained checkboxes.

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.ojInputText#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#asyncValidators.

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.

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
Checkbox Tap Select/unselect the checkbox
Checkbox's Label Tap Select/unselect the corresponding checkbox
Checkbox or Label Press & Hold If hints, help.instruction or messages exist in a notewindow, pop up the notewindow.

Keyboard End User Information

Target Key Action
Checkboxset Tab In Set focus to the first focusable checkbox in the checkboxset. Disabled checkboxes are not focusable. If hints, helpInstruction or messages exist in a notewindow, pop up the notewindow.
Checkbox Space Toggles the checkbox; Iff the checkbox is unselected, it will select it and vice versa.
Checkbox Tab Sets focus to the next focusable checkbox in the checkboxset. Disabled checkboxes are not focusable. If the target is the last focusable checkbox in the checkboxset, focus goes to the next focusable item after the oj-checkboxset.
Checkbox Shift+Tab Sets focus to the previous focusable checkbox in the checkboxset. Disabled checkboxes are not focusable. If the target is the first focusable checkbox in the checkboxset, focus goes to the previous focusable item before the oj-checkboxset.

Accessibility

JET Checkboxset takes care of setting role="group" on the oj-checkboxset element.

For accessibility, set label-hint or associate an oj-label with the form component. If there is no visible label, then to make this accessible to screen reader users, set the label-hint and label-edge='none' which renders an aria-label with the label-hint text. If using an oj-label instead of the label-hint attribute, then put an id on the oj-label component element, and set the form component's labelled-by attribute to be the oj-label component'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.

Migration

Read about current Core Pack limitations to decide when to migrate.
Please make note of the following:

To migrate from oj-checkboxset to oj-c-checkboxset, you need to revise the import statement and references from oj-checkboxset to oj-c-checkboxset in your app. For instance if your application imported ojs/ojcheckboxset this needs to be updated to oj-c/checkboxset. Please note the following changes between the two components below.

options attribute

The options attribute is the only way to provide data to the new oj-c-checkboxset component. Adding oj-option child elements inline is not supported anymore. Besides maintaining its support for DataProvider, the options attribute also accepts an Array of data items. Regardless of the type used for this attribute (whether it's a DataProvider implementation or an Array of data items) the "label" property is required. In the DataProvider case, the "key" of the DataProvider will be used as the checkbox value. The "label" property will provide the text for the checkbox.

label-edge attribute

The enum values for the label-edge attribute have been changed from 'inside', 'provided' and 'none' to 'start', 'inside', 'top' and 'none'. If you are using this component in a form layout and would like the form layout to drive the label edge of this component, leave this attribute unset. The application no longer has to specify 'provided' for this attribute. If you want to override how the label is positioned, set this attribute to the corresponding value.

option-renderer attribute

The option-renderer attribute is not supported anymore and was removed from oj-c-checkboxset. The item label text must be provided directly through the options data.

option-keys attribute

The options-keys attribute is no longer supported and was removed from oj-c-checkboxset. This attribute was used to map an arbitrary DataProvider data item signature to a label and value. The application can instead wrap their DataProvider implementation in a ListDataProviderView with data mapping to match the data shape required by oj-c-checkboxset.

readonly checkboxset visual appearance

A readonly oj-c-checkboxset will render all checkboxes, with an OK check mark for the selected item. This is different from oj-checkboxset where only the selected checkbox was rendered.

messages-custom attribute

The type of the severity property of the messages in the array has changed from Message.SEVERITY_TYPE | Message.SEVERITY_LEVEL, (essentially string | number), to simply 'error' | 'confirmation' | 'info' | 'warning'. These values are the same as the previously supported string values. The application can no longer specify severity as a number, including hardcoded numbers, one of the Message.SEVERITY_LEVEL constants, or the value returned from a call to the Message.getSeverityLevel method.

Removed style classes

The usage of the style classes: oj-choice-direction-column, oj-choice-direction-row that would affect the row or column orientation of the checkboxset are now replaced with the direction attribute. The value of this attribute maps to these style classes as shown below:

  • .oj-choice-direction-column maps to 'column'
  • .oj-choice-direction-row maps to 'row'

The following style classes were removed from oj-c-checkboxset without having a mapping to a new attribute:

  • .oj-checkboxset-input-end
  • .oj-checkboxset-input-start
  • .oj-checkboxset-no-chrome

translations attribute

The translations.required.message-detail attribute has changed to required-message-detail.

refresh method

The refresh method is no longer supported. The application should no longer need to use this method. If the application wants to reset the component (remove messages and reset the value of the component), please use the reset method.

reset method

This method does not synchronously reset the component. The application should wait on the busy context of the component after invoking this method for the changes to appear.

showMessages method

This method does not synchronously show the hidden messages of the component. The application should wait on the busy context of the component after invoking this method for the changes to appear.

Custom Label

Adding a custom <oj-label> for the form component is no longer supported. The application should use the label-hint attribute to add a label for the form component.

The application should no longer need to use an <oj-label-value> component to layout the form component. The application can use the label-edge attribute and label-start-width attribute to customize the label position and label width (only when using start label).

DescribedBy attribute

The described-by attribute is not meant to be set by an application developer directly as stated in the attribute documentation. This attribute is not carried forward to the core pack component.

display-options attribute

The display-options attribute only supports the messages sub-property, converter-hint and validator-hint sub-properties were removed.

Formatted messages

Formatting messages using html tags is not supported in the core pack component.

Usage in Dynamic Form

Using the component in oj-dyn-form is not supported in this release, use oj-dynamic-form instead.

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-checkboxset-input-end
Use this style class to order the checkbox at the end and the label text at the start, even if a theme has a different default order.
Example
<oj-checkboxset id="checkboxsetId" class="oj-checkboxset-input-end">
  <!-- Content -->
</oj-checkboxset>
.oj-checkboxset-input-start
Use this style class to order the checkbox at the start and label text at the end, even if a theme has a different default order.
Example
<oj-checkboxset id="checkboxsetId" class="oj-checkboxset-input-start">
  <!-- Content -->
</oj-checkboxset>
.oj-checkboxset-no-chrome
Use this style class if you don't want the chrome around the set.
Example
<oj-checkboxset id="checkboxsetId" class="oj-checkboxset-no-chrome">
  <!-- Content -->
</oj-checkboxset>
.oj-choice-direction-column
Use this style class to lay out the checkboxes in a column. This is the default.
Example
<oj-checkboxset id="checkboxsetId" class="oj-choice-direction-column">
  <!-- Content -->
</oj-checkboxset>
.oj-choice-direction-row
Use this style class to lay out the checkboxes in a row.
Example
<oj-checkboxset id="checkboxsetId" class="oj-choice-direction-row">
  <!-- Content -->
</oj-checkboxset>

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.

Default

The <oj-checkboxset> element accepts oj-option elements as children. See the oj-option documentation for details about accepted children and slots.

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.

Deprecated:
Since Description
13.0.0 This web component no longer supports launching a context menu.

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.

display-options :Object

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

In the Redwood theme, the sub-properties of the display-options configure whether or not the types of information is shown. The values of these sub-properties are either 'display' or 'none'.

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. The allowed html tags are: span, b, i, em, br, hr, li, ol, ul, p, small, pre. 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.

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. The allowed html tags are: span, b, i, em, br, hr, li, ol, ul, p, small, pre. 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 Redwood theme for clarity only one user assistance text shows to the user. The precedence rules are:

  • help.instruction shows;

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, the label-edge attribute could come from the oj-form-layout's label-edge attribute. The oj-form-layout component uses the MetadataTypes.PropertyBinding provide property to provide and uses the MetadataTypes.ProvideProperty transform property to transform its label-edge attribute to any descendent components that are configured to consume it. For example, if the oj-form-layout's label-edge attribute is set to "top" or "start", and a descendent form component does not have its label-edge attribute set, the form component's label-edge will be the transformed value "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.

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

labelled-by is used to establish a relationship between this component and another element. A common use is to tie the oj-label and the oj-checkboxset together for accessibility. The oj-label custom element has an id, and you use the labelled-by attribute to tie the two components together to facilitate correct screen reader behavior.

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 Message for details. 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. The allowed html tags are: span, b, i, em, br, hr, li, ol, ul, p, small, pre. To format the message detail, you could do this:

A messagesCustom message with severity error will make the component's valid state invalidShown. However, a messagesCustom message, no matter the severity, does not prevent the value from being changed, as well as pushed to the view model.

Messages are shown on an enabled component, but not on a disabled component. On a readonly component, if readonlyMessagesCustom is set to 'confirmationOrInfoMessages', then info and confirmation custom messages are shown.

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.

The renderer function that renders each option. The function should return an oj-option element.

It is not necessary to set the "value" attribute on the oj-option as it is available from the options data.

See options and options-keys for configuring option label and value.

The context parameter passed to the renderer contains the following keys:

options :(DataProvider.<K, D>|null)

A data provider that returns the option items for the Checkboxset. This attribute can be used instead of providing a list of oj-option child elements of the Checkboxset element.

This data provider must implement DataProvider.

  • value in oj.ojCheckboxset.Option must be the row key in the data provider.

Specify the key names to use in the options array.

Depending on options-keys means that the signature of the data does not match what is supported by the options attribute. When using Typescript, this would result in a compilation error.

Best practice is to use a ListDataProviderView with data mapping as a replacement.

However, for the app that must fetch data from a REST endpoint where the data fields do not match those that are supported by the options attribute, you may use the options-keys with any dataProvider that implements DataProvider interface.

(nullable) 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

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.

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. In the Alta theme the input's label will render a required icon.

The Required error text is based on Redwood UX designs, and it is not recommended that it be changed. To override the required error message, use the translations.required attribute. The component's label text is passed in as a token {label} and can be used in the message detail.

When required is set to true, an implicit required validator is created, i.e., new RequiredValidator(). The required validator is the only validator to run during initial render, and its error is not shown to the user at this time; this is called deferred validation. The required validator also runs during normal validation; this is when the errors are shown to the user. See the Validation and Messaging section for details.

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

Running Validation when required property changes

  • if component is valid when required is set to true, then it runs deferred validation on the value property. If the field is empty, the valid state is invalidHidden. No errors are shown to the user.
  • if component is invalid and has deferred messages when required is set to false, then component messages are cleared (messages-custom messages are not cleared) but no deferred validation is run because required is false.
  • 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 when required property changes

  • Only messages created by the component, like validation messages, are cleared when the required property changes.
  • messagesCustom property is not cleared.

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.

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.
reflow Messages, help, hints, and required are all shown inline under the field with no 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.

Events

ojAnimateEnd

Triggered when a default animation has ended.
Deprecated:
Since Description
12.1.0 This web component no longer supports this event.
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:
  • 12.1.0

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 AnimationUtils.

The default animations are controlled via the theme: 

// default animations for notewindow help and hints and messages
$popupTailOpenAnimation: (effect: "zoomIn", transformOrigin: "#myPosition") !default;
$popupTailCloseAnimation: (effect: "none") !default;

// default animations for Redwood's inline messages shown when userAssistanceDensity
// is reflow or efficient.
