		!#en
		Register a callback of a specific event type on Node.<br/>
		Use this method to register touch or mouse event permit propagation based on scene graph,<br/>
		These kinds of event are triggered with dispatchEvent, the dispatch process has three steps:<br/>
		1. Capturing phase: dispatch in capture targets (`_getCapturingTargets`), e.g. parents in node tree, from root to the real target<br/>
		2. At target phase: dispatch to the listeners of the real target<br/>
		3. Bubbling phase: dispatch in bubble targets (`_getBubblingTargets`), e.g. parents in node tree, from the real target to root<br/>
		In any moment of the dispatching process, it can be stopped via `event.stopPropagation()` or `event.stopPropagationImmidiate()`.<br/>
		It's the recommended way to register touch/mouse event for Node,<br/>
		please do not use cc.eventManager directly for Node.<br/>
		You can also register custom event and use `emit` to trigger custom event on Node.<br/>
		For such events, there won't be capturing and bubbling phase, your event will be dispatched directly to its listeners registered on the same node.<br/>
		You can also pass event callback parameters with `emit` by passing parameters after `type`.
		!#zh
		在节点上注册指定类型的回调函数，也可以设置 target 用于绑定响应函数的 this 对象。<br/>
		鼠标或触摸事件会被系统调用 dispatchEvent 方法触发，触发的过程包含三个阶段：<br/>
		1. 捕获阶段：派发事件给捕获目标（通过 `_getCapturingTargets` 获取），比如，节点树中注册了捕获阶段的父节点，从根节点开始派发直到目标节点。<br/>
		2. 目标阶段：派发给目标节点的监听器。<br/>
		3. 冒泡阶段：派发事件给冒泡目标（通过 `_getBubblingTargets` 获取），比如，节点树中注册了冒泡阶段的父节点，从目标节点开始派发直到根节点。<br/>
		同时您可以将事件派发到父节点或者通过调用 stopPropagation 拦截它。<br/>
		推荐使用这种方式来监听节点上的触摸或鼠标事件，请不要在节点上直接使用 cc.eventManager。<br/>
		你也可以注册自定义事件到节点上，并通过 emit 方法触发此类事件，对于这类事件，不会发生捕获冒泡阶段，只会直接派发给注册在该节点上的监听器<br/>
		你可以通过在 emit 方法调用时在 type 之后传递额外的参数作为事件回调的参数列表
		@param type A string representing the event type to listen for.<br>See {
   {#crossLink "Node/EventTyupe/POSITION_CHANGED"}}Node Events{
   {/crossLink}} for all builtin events.
		@param callback The callback that will be invoked when the event is dispatched. The callback is ignored if it is a duplicate (the callbacks are unique).
		@param target The target (this object) to invoke the callback, can be null
		@param useCapture When set to true, the listener will be triggered at capturing phase which is ahead of the final target emit, otherwise it will be triggered during bubbling phase.
		
		@example 
		```js
		this.node.on(cc.Node.EventType.TOUCH_START, this.memberFunction, this);  // if "this" is component and the "memberFunction" declared in CCClass.
		node.on(cc.Node.EventType.TOUCH_START, callback, this);
		node.on(cc.Node.EventType.TOUCH_MOVE, callback, this);
		node.on(cc.Node.EventType.TOUCH_END, callback, this);
		node.on(cc.Node.EventType.TOUCH_CANCEL, callback, this);
		node.on(cc.Node.EventType.ANCHOR_CHANGED, callback);
		node.on(cc.Node.EventType.COLOR_CHANGED, callback);
		```
