jquery ajax获取后台数据后无法输出

今天做ajax获取数据，再浏览器的debugger窗口也看到了数据

ajax代码

$('#userSearch').click(function(){
        $.get("loadAllUsers", function(data){
            alert("Data Loaded: " + data);
        });
});

json数据

{"code":0, "data":"[{"userEmail":"xxx","userId":1,"userName":"zyl","userPassword":"xxx","userStatus":"1","userType":"0"},{"userEmail":"xxx","userId":2,"userName":"zyl","userPassword":"xxx","userStatus":"2","userType":"0"}]"}

后来仔细检查后发现是json格式有问题，data的值是数组不需要“”

如果大家也遇到这个问题，可以看下json是否有问题
