 //相关设置    Set: function (index) {        if (index < 0) {            //鼠标移出容器返回默认状态            this.Each(function (oList, oText, i) {                oList._target = this._width * i;                if (oText) { oText._target = this._height_text; }             })        } else {            //鼠标移到某个滑动对象上            this.Each(function (oList, oText, i) {                oList.className = i == index ?'focus':'';////////////////增加这句就行，给容器增加focus样式的                oList._target = (i <= index) ? this._width_min * i : this._width_min * (i - 1) + this._width_max;                if (oText) { oText._target = (i == index) ? 0 : this._height_text; }            })        }        this.Move();    }
