In some specific scenarios, applying the progress bar effect can improve the user-friendliness of the website, allowing users to grasp the progress and increase their patience with the progress. Otherwise, it may directly lead to the closure of the page, which will eventually cause the website to lose users. The following is the progress effect code implemented using jQuery.

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>脚本之家</title>
<script src="http://libs.baidu.com/jquery/1.9.0/jquery.js"></script>
<style type="text/css">
#progress 
{
 background:white;
 height:20px;
 padding:2px;
 border:1px solid green;
 margin:2px;
}
#progress span 
{
 background:green;
 height:16px;
 text-align:center;
 padding:1px;
 margin:1px;
 display:block;
 color:yellow;
 font-weight:bold;
 font-size:14px;
 width:0%;
}
</style>
<script type="text/javascript"> 
 var progress_node_id = "progress"; 
 function SetProgress(progress) { 
  if (progress) { 
   $("#" + progress_node_id + " > span").css("width", String(progress) + "%"); 
   $("#" + progress_node_id + " > span").html(String(progress) + "%"); 
  } 
 } 
 var i = 0; 
 function doProgress() { 
 if (i > 100) { 
  alert("Progress Bar Finished!"); 
  return; 
 } 
 if (i <= 100) { 
  setTimeout("doProgress()", 500); 
  SetProgress(i); 
  i++; 
 } 
 } 
 $(document).ready(function() { 
  doProgress(); 
 }); 
</script>
</head>
<body>
<h1>jQuery实现进度条效果代码</h1>
<p>原理就是使用 Javascript 控制 SPAN CSS 的宽度（以及其他的样式），刷新查看</p>
<div id="progress"><span></span></div>
</body>
</html>

The above code implements the commonly used progress bar effect. When the progress bar advances, there is a percentage mark, which is very user-friendly.
