Cocos Creator 触摸事件穿透

触摸事件

假设给整个Canvas添加了事件监听。用网页模拟时，鼠标移动，点击子node都会监听到。

    start() {
        this._cfgTouchField();
    }

    _onTouchFieldDown(e) {
        cc.log('table', '_onTouchFieldDown');
    }

    _onTouchFieldMove(e) {
        cc.log('table', '_onTouchFieldMove');
    }

    _onTouchFieldEnd(e) {
        cc.log('table', '_onTouchFieldEnd');
    }

    _cfgTouchField() {
        this.node.on(cc.Node.EventType.MOUSE_DOWN, this._onTouchFieldDown, this);
        this.node.on(cc.Node.EventType.MOUSE_MOVE, this._onTouchFieldMove, this);
        this.node.on(cc.Node.EventType.MOUSE_LEAVE, this._onTouchFieldEnd, this);
        this.node.on(cc.Node.EventType.MOUSE_UP, this._onTouchFieldEnd, this);
    }

网页模拟，鼠标从空白地方移入Toggle的范围时，会触发一次cc.Node.EventType.MOUSE_LEAVE；
然后又是cc.Node.EventType.MOUSE_MOVE
