browserEvents.conditionalBind() function

Bind an event handler that can be ignored if it is not part of the active touch stream. Use this for events that either start or continue a multi-part gesture (e.g. mousedown or mousemove, which may be part of a drag or click).

Signature:

export declare function conditionalBind(node: EventTarget, name: string, thisObject: object | null, func: Function, opt_noCaptureIdentifier?: boolean): Data;

Parameters

Parameter	Type	Description
node	EventTarget	Node upon which to listen.
name	string	Event name to listen to (e.g. 'mousedown').
thisObject	object | null	The value of 'this' in the function.
func	Function	Function to call when event is triggered.
opt_noCaptureIdentifier	boolean	(Optional) True if triggering on this event should not block execution of other event handlers on this touch or other simultaneous touches. False by default.

Returns:

Data
