Table is a commonly used element. Sometimes the order of rows in the table needs to be adjusted. Here is a code example to introduce how to use jquery to achieve this function.

The code example is as follows:

<!DOCTYPE html>
<html>
<head>
<meta charset=" utf-8">
<meta name="author" content="http://www.softwhy.com/" />
<title>脚本之家</title>
<style type="text/css" >
table 
{
background:#F90;
width:400px;
line-height:20px;
}
td 
{
border-right:1px solid gray;
border-bottom:1px solid gray;
}
</style>
<script type="text/javascript" src="mytest/jQuery/jquery-1.8.3.js"></script>
<script type="text/javascript" > 
function up(obj) 
{ 
var objParentTR=$(obj).parent().parent(); 
var prevTR=objParentTR.prev(); 
if(prevTR.length>0) 
{ 
prevTR.insertAfter(objParentTR); 
} 
} 
function down(obj) 
{ 
var objParentTR=$(obj).parent().parent(); 
var nextTR=objParentTR.next(); 
if(nextTR.length>0) 
{ 
nextTR.insertBefore(objParentTR); 
} 
} 
</script>
</head>
<body>
<table border="0" >
<tr>
<td>脚本之家一</td>
<td>脚本之家一</td>
<td>脚本之家一</td>
<td><a href="#" onclick="up(this)">上移</a> <a href="#" onclick="down(this)">下移</a></td>
</tr>
<tr>
<td>脚本之家二</td>
<td>脚本之家二</td>
<td>脚本之家二</td>
<td><a href="#" onclick="up(this)">上移</a> <a href="#" onclick="down(this)">下移</a></td>
</tr>
<tr>
<td>脚本之家三</td>
<td>脚本之家三</td>
<td>脚本之家三</td>
<td><a href="#" onclick="up(this)">上移</a> <a href="#" onclick="down(this)">下移</a></td>
</tr>
<tr>
<td>脚本之家四</td>
<td>脚本之家四</td>
<td>脚本之家四</td>
<td><a href="#" onclick="up(this)">上移</a> <a href="#" onclick="down(this)">下移</a></td>
</tr>
<tr>
<td>脚本之家五</td>
<td>脚本之家五</td>
<td>脚本之家五</td>
<td><a href="#" onclick="up(this)">上移</a> <a href="#" onclick="down(this)">下移</a></td>
</tr>
</table>
</body>
</html>

The above code simply implements jQuery to adjust the upper and lower order of table rows tr. I hope this code can help everyone.
