_autoMove : function(){
        var that = this,
            dis = -1;
        this._auto = setInterval(function(){
            that._setTransTime(that._slider,'.3');
            that._sliderMoving = true;
            that._setVisualItem(dis);
            that._changeItem(dis);
        },3000);
    },

代码大概是这样，在正常情况下程序按照期待的结果运行，但手动待机或自动进入待机状态后，运行结果就不正常了，不知有人遇到过否？求解答
