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 default slot is the button's text label. The
<oj-button>element accepts plain text or DOM nodes as children for the default slot. A default slot label is required for all buttons for accessibility purposes. The label can be hidden using the display attribute.If a text node is provided it will be wrapped in a span.
Examples
Initialize the Button with child content specified:
<oj-button> <span>myValue</span> </oj-button>Initialize the Button with data-bound child content specified in a span:
<oj-button> <span data-bind='text: myText'></span> </oj-button>Initialize the Button with data-bound child content specified without a container element:
<oj-button> <!-- ko text: myText --><!--/ko--> </oj-button> -
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> -
endIcon
-
The
endIconslot is the button's end icon. The<oj-button>element accepts DOM nodes as children with the endIcon slot.Example
Initialize the Button with child content specified for the endIcon:
<oj-button> <span>myValue</span> <span slot='endIcon' class='myIconClass'></span> </oj-button> -
startIcon
-
The
startIconslot is the button's start icon. The<oj-button>element accepts DOM nodes as children with the startIcon slot.Example
Initialize the Button with child content specified for the startIcon:
<oj-button> <span slot='startIcon' class='myIconClass'></span> <span>myValue</span> </oj-button>
Attributes
-
chroming :string
-
Indicates in what states the button has chrome (background and border).
The default chroming varies by theme and containership as follows:
- If the button is in a buttonset or toolbar, then the default chroming is the current
chromingvalue of the nearest such container. - Else, if
$buttonChromingOptionDefaultis set in the current theme as seen in the example below, then that value is the chroming default. - Else, the default chroming is
"full".
Once a value has been set on this button attribute, that value applies regardless of theme and containership.
Supported Values:
Name Type Description "full"string In typical themes, full-chrome buttons always have chrome. "half"string In typical themes, half-chrome buttons acquire chrome only in their hover, active, and selected states. Half-chroming is recommended for buttons in a toolbar. (This is the toolbar default in most themes.) "outlined"string In typical themes, outlined buttons are similar to half-chrome buttons, but have a border in the default state. Names
Item Name Property chromingProperty change event chromingChangedProperty change listener attribute (must be of type function) on-chroming-changedExamples
Initialize the Button with the
chromingattribute specified:<oj-button chroming='half'></oj-button>Get or set the
chromingproperty after initialization:// getter var chromingValue = myButton.chroming; // setter myButton.chroming = 'half';Set the default in the theme (SCSS) :

-
disabled :boolean
-
Disables the button if set to
true.After create time, the
disabledstate should be set via this API, not by setting the underlying DOM attribute.- Default Value:
false
Names
Item Name Property disabledProperty change event disabledChangedProperty change listener attribute (must be of type function) on-disabled-changedExamples
Initialize the Button with the
disabledattribute specified:<oj-button disabled='true'></oj-button>Get or set the
disabledproperty after initialization:// getter var disabledValue = myButton.disabled; // setter myButton.disabled = true; -
display :string
-
Whether to display both the label and icons (
"all") or just the icons ("icons"). In the latter case, the label is displayed in a tooltip instead, unless a tooltip was already supplied at create time.For accessibility, a JET Button must always have a label set via the default slot, even if it is icon-only.
- Default Value:
"all"
Supported Values:
Name Type Description "all"string Display both the label and icons. "icons"string Display only the icons. Names
Item Name Property displayProperty change event displayChangedProperty change listener attribute (must be of type function) on-display-changedExamples
Initialize the Button with the
displayattribute specified:<oj-button display='icons'></oj-button>Get or set the

translations :Object|null
-
A collection of translated resources from the translation bundle, or
nullif 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.
Names
Item Name Property translationsProperty change event translationsChangedProperty change listener attribute (must be of type function) on-translations-changedExamples
Initialize the component, overriding some translated resources and leaving the others intact:
<!-- Using dot notation --> <oj-some-element translations.some-key='some value' translations.some-other-key='some other value'></oj-some-element> <!-- Using JSON notation --> <oj-some-element translations='{"someKey":"some value", "someOtherKey":"some other value"}'></oj-some-element>Get or set the
translationsproperty after initialization:// Get one var value = myComponent.translations.someKey; // Set one, leaving the others intact. Always use the setProperty API for // subproperties rather than setting a subproperty directly. myComponent.setProperty('translations.someKey', 'some value'); // Get all var values = myComponent.translations; // Set all. Must list every resource key, as those not listed are lost. myComponent.translations = { someKey: 'some value', someOtherKey: 'some other value' };
Events
-
ojAction
-
Triggered when a button is clicked. This will be triggered by keyboard events as well as mouse/touch events.
To ensure keyboard accessibility, the only correct, supported way to react to the click of a button is to listen for this event. Click listeners and
hrefnavigation should not be used.- Since:
- 5.0.0
Examples
Specify an
ojActionlistener via the DOM attribute:<oj-button on-oj-action='[[listener]]'></oj-button>Specify an
ojActionlistener via the JavaScript property:myButton.onOjAction = listener;Add an
ojActionlistener via theaddEventListenerAPI:myButton.addEventListener('ojAction', listener);
