The example in this article describes how jQuery simply implements a loading progress bar when submitting data. Share it with everyone for your reference, the details are as follows:

The html part of the code is as follows, copy and import the class library to use

<html>
<head>
<style type="text/css">
 #bg{ display: none; position: absolute; top: 0%; left: 0%; width: 100%; height: 100%; background-color: black; z-index:1001; -moz-opacity: 0.2; opacity:.2; filter: alpha(opacity=70);}
 .loading{display: none; position: absolute; top: 50%; left: 50%; z-index:1002; }
 </style>
</head>
<body>
  <div id="bg"></div>
  <input type="button" value="Save" id="btnSave" name="btnSave" />
  <div class="loading"><img src="loading.gif"></div>
</body>
</html>

Part of the jQuery code is as follows: 

<script src="jquery-1.11.0.min.js" type="text/javascript"></script><!--自己下载类库-->
<script type="text/javascript">
$(function(){
  $("#btnSave").click(function(){
    $("#bg,.loading").show();
    $.ajax({
      async:false,
      url:"time.php",
      type:"post",
      data:{},
      success:function(mes){
        $("#bg,.loading").show();
      }
    })
  })
})
</script>

php code: 

for($i=0;$i<10000000;$i++){
}
