如何使用jQuery解析这段json类型的数据

怎么使用jQuery解析这段json类型的数据
[{"objName":"datalist","objUser":[{"sUserName":"JSON0","sAddress":"中国-北京-海淀0号"},{"sUserName":"JSON1","sAddress":"中国-北京-海淀1号"},{"sUserName":"JSON2","sAddress":"中国-北京-海淀2号"},{"sUserName":"JSON3","sAddress":"中国-北京-海淀3号"},{"sUserName":"JSON4","sAddress":"中国-北京-海淀4号"}]}]


这是我写的。搞不定啊.

$(function() {

	var json = [{"objName":"datalist","objUser":[{"sUserName":"JSON0","sAddress":"中国-北京-海淀0号"},{"sUserName":"JSON1","sAddress":"中国-北京-海淀1号"},{"sUserName":"JSON2","sAddress":"中国-北京-海淀2号"},{"sUserName":"JSON3","sAddress":"中国-北京-海淀3号"},{"sUserName":"JSON4","sAddress":"中国-北京-海淀4号"}]}]

    var data = eval('(' + json + ')');

    alert(data.objName);

    $.each(data.objUser,

    function(i, o) {

        alert(o.sAddress);

    });

})

我要弹出提示：datalist,然后是每个sAddress的值


求高人指点

------解决方案--------------------

var json = [{"objName":"datalist","objUser":[{"sUserName":"JSON0","sAddress":"中国-北京-海淀0号"},{"sUserName":"JSON1","sAddress":"中国-北京-海淀1号"},{"sUserName":"JSON2","sAddress":"中国-北京-海淀2号"},{"sUserName":"JSON3","sAddress":"中国-北京-海淀3号"},{"sUserName":"JSON4","sAddress":"中国-北京-海淀4号"}]}];

for(i in json){

     alert(json[i].objName);

     for(s in json[i].objUser){

        alert(json[i].objUser[s].sAddress);

       }

}

json变量本来就是JSON格式的了，LZ为什么还要用var data = eval('(' + json + ')');把这红色这句去了。

$(function() {

    var json = [

                  {

                      "objName":"datalist",

                      "objUser":[

                                  {"sUserName":"JSON0","sAddress":"中国-北京-海淀0号"},

                                  {"sUserName":"JSON1","sAddress":"中国-北京-海淀1号"},

                                  {"sUserName":"JSON2","sAddress":"中国-北京-海淀2号"},

                                  {"sUserName":"JSON3","sAddress":"中国-北京-海淀3号"},

                                  {"sUserName":"JSON4","sAddress":"中国-北京-海淀4号"}
