cocos2d-js节点以及子类单点触摸事件监听

//创建一个事件监听器 OneByOne
var listener = cc.EventListener.create({
    event: cc.EventListener.TOUCH_ONE_BY_ONE,
    swallowTouches: true, //设置是否吞没事件，在onTouchBegan方法返回true时吞掉事件，不再向下传递。
    onTouchBegan: function (touch, event) { //实现onTouchBegan事件处理回调函数
        var target = event.getCurrentTarget(); //获取事件所绑定的target, 通常是cc.Node及其子类
        //获取当前触摸点相对于按钮所在的坐标
        var locationInNode = target.convertToNodeSpace(touch.getLocation());
        var s = target.getContentSize();
        var rect = cc.rect(0, 0, s.width, s.height);
        //判断触摸点是否在按钮范围内
        if (cc.rectContainsPoint(rect, locationInNode)) {
            cc.log("sprite began... x = " + locationInNode.x + ", y = " + locationInNode.y);
            target.opacity = 180;
            return true;
        }
        return false;
    },
    onTouchMoved: function (touch, event) { //实现onTouchMoved事件处理回调函数, 触摸移动时触发
        // 移动当前按钮精灵的坐标位置
        var target = event.getCurrentTarget();
        var delta = touch.getDelta(); //获取事件数据:delta
        target.x += delta.x;
        target.y += delta.y;
    },
    onTouchEnded: function (touch, event) { //实现onTouchEnded事件处理回调函数
        var target = event.getCurrentTarget();
        cc.log("sprite onTouchesEnded.. ");
        target.setOpacity(255);
    }
});
cc.eventManager.addListener(listener, this);
