jquery声音没有播放

Question

当div的x位置值超过50时，我想要播放声音。我用箭头键控制div。

我猜测audioElement.play()无法正常工作。

声音和警报都不会弹出（函数playSound）

First your sound handle was out of scope, so i defined it in window:
 window.audioElement = audioElement = blabla
Second you were trying to compare object with a number. Don't need to wrap x.left in jquery. 
if (x.left>50)
