从excel表中获取数据时我想使用动态进度条

Question

我想插入进度条（引导程序）。当数据从 excel 表中获取到下拉列表框时，它大约需要 5 秒。直到我想要进度条填充网页。给一些想法。

I guess you are looking for some preloader shown on your page when an event gets triggered..I have written a piece code where you can achieve that..

查看：

<ul id="prloader" style="display:none">
<li>
<img src="~/images/loader.gif" /></li>
<li id="msg">Processing. Please Wait...</li>
</ul>

Jquery（如果你使用 ajax 调用）：

 $('****').change(function(){        //You can have any other event based on your requirement..

  $('#prloader').show();

  $.ajax({
  url:"../../Controller/Action",
  success:function(response){

   //Have your logic here


   $('#prloader').hide();

  },
  error:function(){

  $('#prloader').hide();

  }
  });
 });
