jquery sound not playing

Question

當div的x位置值超過50時，我想播放聲音。我用箭頭鍵控制div。

我猜audioElement.play()不工作。

無論是聲音還是警報彈出（函數playSound）下面

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)
