demo二：


代码如下:

<script src="jquery-1.6.2.min.js"></script>

<input type="checkbox" id="ckAll" />check all<br />
<input type="checkbox" name="sub" />1<br />
<input type="checkbox" name="sub"/>2<br />
<input type="checkbox" name="sub"/>3<br />
<input type="checkbox" name="sub"/>4<br />

<script>

$("#ckAll").click(function() {
    $("input[name='sub']").prop("checked", this.checked);
  });

$("input[name='sub']").click(function() {
    var $subs = $("input[name='sub']");
    $("#ckAll").prop("checked" , $subs.length == $subs.filter(":checked").length ? true :false);
  });

</script>
