此代码工作正常。我在这里的问题是进度条。某些曲目没有完全填写进度条。例如，如果一个轨道只有2分钟长，它基本上不会完成进度容器。如果曲目超过6分钟，则进度条将移动到播放器容器之外。

我的问题如何创建一个进度条，无论曲目的持续时间有多长，它都会完全加载或完成进度条。假设我们对进度条容器的长度有特定的宽度。

以下是jsfiddle http://jsfiddle.net/vUpeC/

中的代码

Answer 1

假设持续时间属性运作正常，我认为您不需要增加＆＃34;进展＆＃34;到了2.

这个

 $('#progressbar').css({'width' : progress * 2});

应该是

 $('#progressbar').css({'width' : progress+'%' });
