1、全选
$("#btn1").click(function(){
$("input[name='checkbox']").attr("checked","true");
})
2、取消全选（全不选）
$("#btn2").click(function(){
$("input[name='checkbox']").removeAttr("checked");
})
3、选中所有奇数
$("#btn3").click(function(){
$("input[name='checkbox']:odd").attr("checked","true");
})
4、选中所有偶数
$("#btn6").click(function(){
$("input[name='checkbox']:even").attr("checked","true");
})
5、反选
$("#btn4").click(function(){
$("input[name='checkbox']").each(function(){
if($(this).attr("checked"))
{
$(this).removeAttr("checked");
}
else
{
$(this).attr("checked","true");
}
})
})
或者
$("#invert").click(function(){
$("#ruleMessage [name='delModuleID']:checkbox").each(function(i,o){
$(o).attr("checked",!$(o).attr("checked"));
});
});
6、获取选择项的值
var aa="";
$("#btn5").click(function(){
$("input[name='checkbox']:checkbox:checked").each(function(){
aa+=$(this).val()
})
document.write(aa);
})
})
7、遍历选中项
$("input[type=checkbox][checked]").each(function(){
//由于复选框一般选中的是多个,所以可以循环输出
alert($(this).val());
});

<head runat="server">
<title>无标题页</title>
<script src="js/jquery-1.6.min.js" type="text/javascript"></script>
<script type="text/javascript">
jQuery(function($){
//全选
$("#btn1").click(function(){
$("input[name='checkbox']").attr("checked","true");
})
//取消全选
$("#btn2").click(function(){
$("input[name='checkbox']").removeAttr("checked");
})
//选中所有基数
$("#btn3").click(function(){
$("input[name='checkbox']:even").attr("checked","true");
})
//选中所有偶数
$("#btn6").click(function(){
$("input[name='checkbox']:odd").attr("checked","true");
})
//反选
$("#btn4").click(function(){
$("input[name='checkbox']").each(function(){
if($(this).attr("checked"))
{
$(this).removeAttr("checked");
}
else
{
$(this).attr("checked","true");
}
})
})
//或许选择项的值
var aa="";
$("#btn5").click(function(){
$("input[name='checkbox']:checkbox:checked").each(function(){
aa+=$(this).val()
})
document.write(aa);
})
})
