Jquery checkbox全选容易用法

1. 全选或全部取消

//全选或全部取消    function checkAll(){	    $("input[name='xxx']").attr("checked",$("#checkAll").attr("checked")==undefined?false:true);	        }

?2. 获取被选中项的值存放于数组中

var allChecked = $("input[name='xxx']:checked");var ids = [];//循环拼装被选中项的值allChecked .each(function(i){            ids.push($(this).val());});

?3. 获取未被选中项的值存放于数组中?

var notChecked = $("input[name='xxx']").not("input:checked");var ids = [];//循环拼装未被选中项的值notChecked.each(function(i){    removeIds.push($(this).val());});
