Bootstrap进度条超过100％

Question

我正在制作带有进度条的codeingiter文件上传脚本。 在我的Java脚本函数上，当我单击图像进行上传时，它会触发进度条以设定的时间间隔启动。

但是由于某种原因，当达到100％时，它仍会继续超过100％。

问题：进度条达到100％时，如何在脚本上强制停止进度条？

<div class="row">
<div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">
<div class="progress progress-striped active">
<div class="progress-bar" role="progressbar" aria-valuenow="0"  aria-valuemin="0" aria-valuemax="100" style="width: 0%">
<span class="sr-only">0% Complete</span>

我发现了我的问题

在这里需要有data-percentage =“ 100”

<div class="row">
<div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">
<div class="progress progress-striped active">
<div class="progress-bar" role="progressbar" data-percentage="100"  aria-valuenow="0"  aria-valuemin="0" aria-valuemax="100" style="width: 0%">
<span class="sr-only">0% Complete</span>
</div>
</div>
<div class="image"></div>
</div>
</div>

脚本
