Question

ajax 请求问题，能返回值但不能正确进入到success

$(function (){ var userurl="json.asp" $.ajax({ type: "get", url:userurl, async: true, dataType: "json", success: function(data) { alert(data) }, error: function(xhr, textStatus, errorThrown){ alert("错误") } }) });
请问上面的请求代码，怎么都进不到成功里面呢，都是弹出错误
我用火狐的Firebug看到有返回值为
{"count":"2",items:[{"jt_id":"1","jt_name":"t1","jt_createtime":"2013-12-7 15:01:40","us":"a"},{"jt_id":"2","jt_name":"t2","jt_createtime":"2013-12-7 23:20:29","us":"b"}]}

$(function (){ var tt={"count":"2",items:[{"jt_id":"1","jt_name":"t1","jt_createtime":"2013-12-7 15:01:40","us":"a"},{"jt_id":"2","jt_name":"t2","jt_createtime":"2013-12-7 23:20:29","us":"b"}]} alert(tt.items[1].jt_id)//这样也能够正常得到值})
麻烦帮我看看是怎么回事呢，json格式也应该是正确的，为什么就进不到正确的地方，谢谢

Answer 1

{
    "count": "2",
    items: [{ // 给items加双引号试试，JSON格式非常严格的
        "jt_id": "1",
        "jt_name": "t1",
        "jt_createtime": "2013-12-7 15:01:40",
        "us": "a"
    }, {
        "jt_id": "2",
        "jt_name": "t2",
        "jt_createtime": "2013-12-7 23:20:29",
        "us": "b"
    }]
}

先用firebug看看错误信息是什么？
