jquery返回json数据

[flyingheart2010]

我想再从后台返回一个变量和一个list数组，在js页面页$.post('listUserjson.action?now='+now,"username":username,"name":name},function(data){
alert(data);
var pageCount = data["pageCount"];
alert(pageCount);
alert(data)得到：
[{"pageCount":7,"list2":[{"id":"3","username":"001","password":"111111","name":"s1"},{"id":"4","username":"002","password":"111111","name":"s3"},{"id":"5","username":"100","password":"111111","name":"t3"}]}]
alert(pageCount);得到:undefined,那怎么得到pageCount和list2?

data[0].pageCount

data是一个数组

[追梦的人]

var arr=eval('('+data+')');
if(arr.length>0) {
for(var i = 0 ; i < arr.length ; i ++){
alert(arr[i].column_name );
alert(arr[i].comments ); }
}


给分吧 呵呵

[飞跃颠峰]

alert(data.pageCount);
for (var i=0; i<data.list2.length; i++)
alert(data.list2[i].id);
