Jquery checkbox全选简单用法

1. 全选或全部取消

Js代码

1. //全选或全部取消
2. function checkAll(){
3. $("input[name='xxx']").attr("checked",$("#checkAll").attr("checked")==undefined?false:true);
4. }

//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

Js代码

1. var allChecked = $("input[name='xxx']:checked");
2. var ids = [];
3. //循环拼装被选中项的值
4. allChecked .each(function(i){
5. ids.push($(this).val());
6. });

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

Js代码

1. var notChecked = $("input[name='xxx']").not("input:checked");
2. var ids = [];
3. //循环拼装未被选中项的值
4. notChecked.each(function(i){
5. removeIds.push($(this).val());
6. });

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());});
