[英]Bootstrap Progress Bar Going Past 100%
我正在制作帶有進度條的codeingiter文件上傳腳本。 在我的Java腳本函數上,當我單擊圖像進行上傳時,它會觸發進度條以設定的時間間隔啟動。
但是由於某種原因,當達到100%時,它仍會繼續超過100%。
問題:進度條達到100%時,如何在腳本上強制停止進度條?
<div class="row">

我發現了我的問題
在這里需要有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>
