Jquery checkbox全选简单用法

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);
}

//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());
});

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());
});

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());
});
