jQuery 全选/反选以及单击行改变背景色实例

我先把CSS样式放出来，其实这个可以直接忽略

body{margin:0;padding:0;font-size:12px;font-family:微软雅黑;} 
.datagrid{width:100%;} 
.datagird tr th{background-color:#191970; font-size:14px;} 
.datagrid tr th, .datagrid tr td{border:1px solid #ccc; border-collapse:collapse;} 
/* 选中行样式 */ 
.table-row-selected{background:#fff68f;}

我们再来看页面HTML结构

<div id="page"> 
<table class="datagrid" cellpadding="0" cellspacing="0"> 
<thead> 
<tr> 
<th><input id="CheckAll" name="checkall" type="checkbox" /></th> 
<th>ID</th> 
<th>标题</th> 
<th>发布人</th> 
<th>发布时间</th> 
</tr> 
</thead> 
<tbody> 
<tr> 
<td align="center"><input type="checkbox" name="check" /></td> 
<td align="center" width="5%">1</td> 
<td>阿里做对了哪三件事？</td> 
<td align="center" width="10%">internet</td> 
<td align="center" width="15%">2013-07-01</td> 
</tr> 
<tr> 
<td align="center"><input type="checkbox" name="check" /></td> 
<td align="center" width="5%">2</td> 
<td>大盘点：被互联网改写的16个传统行业</td> 
<td align="center" width="10%">internet</td> 
<td align="center" width="15%">2013-07-01</td> 
</tr> 
<tr> 
<td align="center"><input type="checkbox" name="check" /></td> 
<td align="center" width="5%">3</td> 
<td>如果智能手机市场有变，酷派们怎么办？</td> 
<td align="center" width="10%">internet</td> 
<td align="center" width="15%">2013-07-01</td> 
</tr> 
<tr> 
<td align="center"><input type="checkbox" name="check" /></td> 
<td align="center" width="5%">4</td> 
<td>看看福特们是如何抵御谷歌苹果的？</td> 
<td align="center" width="10%">internet</td> 
<td align="center" width="15%">2013-07-01</td> 
</tr> 
</tbody> 
</table> 
</div>

实现功能
1）单击行改变背景色

$(".datagrid tbody tr").bind("click", function () { 
var oThis = $(this); 
if (oThis.hasClass("table-row-selected")) { 
oThis.removeClass("table-row-selected"); 
oThis.children("td:eq(0)").children("input[name='check']").removeAttr("checked"); 
} else { 
oThis.addClass("table-row-selected"); 
oThis.children("td:eq(0)").children("input[name='check']").attr("checked", "checked"); 
} 
});

2）全选/反全选功能（未完成，待续）
