表格大家都十分熟悉，如今的CSS也使得表格的布局越来越光彩耀人。但是，无论如何，都掩饰不了那些包装下的死板。

那么如何让那些死板的数据更具有可读性、可用性，能够让我们那些数据在“动”呢？

下面我们使用jquery+ajax 来为表格注入些活力。主要实现的目的就是：将表格的列标题转化为按钮，点击不同的列标题，便按相应的列对数据进行排序。比如学生信息表，我点击“生日”列，这张表便按生日排序将结果呈现在我们面前。使用ajax来调用本页也避免了刷新页面所带来的折磨。
下面我给出最基本的jsp页面

详细代码如下

复制代码代码如下:www.mb5u.com

 
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%> 
<% 
String path = request.getContextPath(); 
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; 
%> 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<html> 
<head> 
<base href="<%=basePath%>"> 
<title>My JSP 'sorttable.jsp' starting page</title> 
<meta http-equiv="pragma" content="no-cache"> 
<meta http-equiv="cache-control" content="no-cache">

<!-- 
<link rel="stylesheet" type="text/css" href="styles.css">

<script type="text/javascript" src="js/jquery-1.4.4.js"></script> 
</head> 
<body> 
<table class = "sorttable" style="background-color: gray;color: white;"> 
<thead> 
<tr > 
<th></th> 
<th class="sort-alpha">Title</th> 
<th>Author</th> 
<th>PublishDate</th> 
<th>Price</th> 
</tr> 
</thead> 
<tbody> 
<tr> 
<td><img src="<%=path %>/images/javascript.jpg" width="40" height="50" alt="JavaScript" /></td> 
<td>JavaScript</td> 
<td> Douglas Crockford </td> 
<td> May 2008</td> 
<td>$31.02</td>

<tr>

<td>$31.02</td>

<td><img src="<%=path %>/images/Learning.jpg" width="40" height="50" alt="Learning Mambo" /></td> 
<td>Learning Mambo</td> 
<td>Douglas Paterson</td> 
<td> Mar 2006</td> 
<td>$31.02</td> 
</tr> 
<tr> 
<td><img src="<%=path %>/images/Think.jpg" width="40" height="50" alt="Thinking in java" /></td> 
<td>Thinking in java</td>

</tr> 
</tbody> 
</table> 
</body> 
</html> 

第一步：为表格添加奇偶行交替背景

复制代码代码如下:www.mb5u.com

 
<style type="text/css"> 
.even{ 
background-color: #E8A824; 
} 
.odd{ 
background-color:#74411B; 
} 
</style> 

第二步：按字母排序
实现基于表格的Title列进行排序
<thclass="sort-alpha">Title</th>
为Title定义了一个sort-alpha类

复制代码代码如下:www.mb5u.com

 
<script type="text/javascript" language="javascript"> 
$(document).ready(function(){ 
var alternateRowColors = function($table){ 
$('tbody tr:odd',$table).removeClass('even').addClass('odd'); 
$('tbody tr:even',$table).removeClass('odd').addClass('even') 
}; 
$('table.sorttable').each(function (){ 
var $table =$(this); 
alternateRowColors($table); 
$('th',$table).each(function(column){ 
var $header = $(this); 
if($header.is('.sort-alpha')){ 
$header.addClass('clickable').hover(function(){ 
$header.addClass('hover'); 
},function(){ 
$header.removeClass('hover'); 
}).click(function(){ 
var rows = $table.find('tbody>tr').get(); 
rows.sort(function(a,b){ 
var keyA =$(a).children('td').eq(column).text().toUpperCase(); 
var keyB =$(b).children('td').eq(column).text().toUpperCase(); 
if(keyA<keyB) return -1; 
if(keyA>keyB) return 1; 
return 0; 
}); 
$.each(rows,function(index,row){ 
$table.children('tbody').append(row); 
}); 
alternateRowColors($table); 
}); 
} 
}); 
}); 
}); 
</script>
