為了確保點選時候播放

_cancelSelectObject: function (id) {
    	var _this = this;
    	_this._selected = false;

		if(_this._animate){
			_this._animate._play = false;
		}
    },

    /**
     * [__selectObject 設定選中和取消方法]
     * @param {String} id [description]
     */
    __selectObject: function (data){
    	var _this = this;
    	if(data.id != _this.m_id) {
			return;
		}
		_this._selected = true;

		if(_this._animate && _this._animate.play &&  !_this._animate._play ){
			_this._animate._play = true;
			_this._animate.play(0);
		}
    },
 

實現程式碼

__setAnimate: function (data) {
		var _this = this;

		if(data.wraperId != _this.m_id) {
			return;
		}

					};

					_this.m_viewElement.appendChild(img);
				}

				_this._animate.play = function(index){
