我想使用jQuery使我的跨度的背景位置每秒下降10像素。这是一个很好的方法吗？

我一直在玩jQuery animate，延迟，CSS和一些 setTimeout 函数，但我不能得到任何工作。

I'm trying to make my y-position go from 0 to 100 in increments of 10 pixels, and then stop the animation.

推荐答案

jQuery不能正确地设置背景位置的动画，因为需要动画两个值而不是一个。此处的解释和解决方案：

jQuery can't animate background position properly because of the need to animate two values instead of just one. Explanation and solution here:
