我正在制作带有进度条的codeingiter文件上传脚本。在我的java脚本函数中,当我单击要上载的图像时,它会触发进度条以设置的间隔开始。
但出于某种原因,当它达到100%时,它仍然会继续超过100%。
问题:在我的脚本中,只要进度条达到100%,我该如何强制我的进度条停止?

答案 0 :(得分:0)
我发现了我的问题
此处需要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>
