下面的代码比较全，是基于js的控制原理实现
<script src="http://img.jb51.net/jslib/jquery/jquery14.js"></script>
<script type="text/javascript">
//全选
function CheckedAll(){
$(':checkbox').attr('checked','checked');
}
//全不选
function CheckedNo(){
$(':checkbox').attr('checked','');
}
//反选
function CheckedRev(){
var arr = $(':checkbox');
for(var i=0;i<arr.length;i++){
arr[i].checked = ! arr[i].checked;
}
}
</script>
<body>
<div>
<input id="CheckAll" type="checkbox" />
<input name="subBox" type="checkbox" />
<input name="subBox" type="checkbox" />
<input name="subBox" type="checkbox" />
<input name="subBox" type="checkbox" />
</div>
<input type="button" name="btnCheckedAll" value="全 选" onclick="javascript:CheckedAll();" />
<input type="button" name="btnCheckedNo" value="全不选" onclick="javascript:CheckedNo();" />
<input type="button" name="btnCheckedRev" value="反 选" onclick="javascript:CheckedRev();" />
</body>
