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.
-
nodeTemplate
-
The
nodeTemplate
slot is used to specify the template for creating nodes of the sunburst. The slot content must be wrapped in a single <template> element. The content of the template should be a single <oj-sunburst-node> element. See the oj-sunburst-node doc for more details.When the template is executed for each node, it will have access to the components's binding context containing the following properties:
- $current - an object that contains information for the current node. (See oj.ojSunburst.NodeTemplateContext or the table below for a list of properties available on $current)
- alias - if data-oj-as attribute was specified, the value will be used to provide an application-named alias for $current.
Properties of $current:
Name Type Description componentElement
Element The <oj-sunburst> custom element data
Object The data object of the node index
number The zero-based index of the current node key
any The key of the current node parentData
Array An array of data objects of the outermost to innermost parents of the node parentKey
any The key of the parent node -

-
The
rootNodeContentTemplate

tooltipTemplate
-

touch-response :"touchStart"|"auto"
Data visualizations require a press and hold delay before triggering tooltips and rollover effects on mobile devices to avoid interfering with page panning, but these hold delays can make applications seem slower and less responsive. For a better user experience, the application can remove the touch and hold delay when data visualizations are used within a non scrolling container or if there is sufficient space outside of the visualization for panning. If touchResponse is touchStart the element will instantly trigger the touch gesture and consume the page pan events. If touchResponse is auto, the element will behave like touchStart if it determines that it is not rendered within scrolling content and if panning is not available for those elements that support the feature.- Default Value:

Methods
-
getContextByNode(node) : {(oj.ojSunburst.NodeContext|null)}
-
Returns an object with context for the given child DOM node. This will always contain the subid for the node, defined as the 'subId' property on the context object. Additional component specific information may also be included. For more details on returned objects, see context objects.
Parameters:
Name Type Argument Description node
Element <not nullable>
The child DOM node Returns:
The context for the DOM node, or
null
when none is found.- Type
- (oj.ojSunburst.NodeContext|null)
-
getNode(subIdPath) : {(oj.ojSunburst.DataContext|null)}
-
Returns an object with the following properties for automation testing verification of the node with the specified subid path.
Parameters:
Name Type Description subIdPath
Array The array of indices in the subId for the desired node Deprecated:
Since Description 7.0.0
The use of this function is no longer recommended. Returns:
An object containing properties for the node, or null if none exists.

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.

Example
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:
