PhotoFilter的速度控制不了？
这个是我的关于图片处理的js（新公司给我做的，之前别人写完了的），要我调整一下图片切换的速度。但是这个里面的speed没法调速度啊。我用PhotoFilter.Speed(5000),速度还是没有变呢。我不知道原因是在哪里。function PhotoFilter(){

代码不全，我就没看到Speed或者_speed被用过。

}
影响图片切换速度的应该是下面这句。
this.theTimer = setTimeout(this.ObjName + '.NextPhoto()', this.ArrTime[intNP]);
this.ArrTime[intNP]是间隔时间。
补充：.NET技术 , C#
