jQuery+Ajax實(shí)現(xiàn)表格數(shù)據(jù)不同列標(biāo)題排序(為表格注入活力)

表格大家都十分熟悉，如今的CSS也使得表格的布局越來越光彩耀人。但是，無論如何，都掩飾不了那些包裝下的死板。

那么如何讓那些死板的數(shù)據(jù) 更具有可讀性、可用性，能夠讓我們那些數(shù)據(jù)在“動(dòng)”呢？

下面我們使用jquery+ajax 來為表格注入些活力。主要實(shí)現(xiàn)的目的就是：將表格的列標(biāo)題轉(zhuǎn)化為按鈕，點(diǎn)擊不同的列標(biāo)題，便按相應(yīng)的列對(duì)數(shù)據(jù)進(jìn)行排序。比如學(xué)生信息表，我點(diǎn)擊“生日”列，這張表便按生日排序?qū)⒔Y(jié)果呈現(xiàn)在我們面前。使用ajax來調(diào)用本頁也避免了刷新頁面所帶來的折磨。
下面我給出最基本的jsp頁面

詳細(xì)代碼如下

復(fù)制代碼代碼如下:

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; 
%>

第一步：為表格添加奇偶行交替背景

復(fù)制代碼代碼如下:

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

第二步：按字母排序
實(shí)現(xiàn)基于表格的Title列進(jìn)行排序
thclass="sort-alpha">Title/th>
為Title定義了一個(gè)sort-alpha類

復(fù)制代碼代碼如下:

 
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(keyAkeyB) return -1; 
if(keyA>keyB) return 1; 
return 0; 
}); 
$.each(rows,function(index,row){ 
$table.children('tbody').append(row); 
}); 
alternateRowColors($table); 
}); 
} 
}); 
}); 
}); 
/script>
