jQuery嵌套响应数组问题

Question

我有一个验证用户名/密码的函数：

这是JSON RESPONSE：

{"data":{"user_id":"2","auth_token":"x"},"result": {"errorcode":"","messages":"Success:Logged On","rstatus":1}}

我希望能够解析出user_id，auth_token，errorcode，message，rstatus

以下是调用的JQuery代码：

function authenticate(userName, password) {
    $.ajax({
        url: 'index.php?action=login',
        type: 'POST',
        contentType: 'application/x-www-form-urlencoded; charset=UTF-8',
        data: 'username=' + userName + '&password=' + password,
        dataType: 'json',
        async: true,
        success: function (response) {
            //i need to parse out the data here
        }
    });
}

任何建议都将不胜感激。

Answer 1

怎么样：

var user_id = response.data.user_id, 
    auth_token = response.data.auth_token, 
    errorcode = response.result.errorcode, 
    messages = response.result.messages, 
    rstatus = response.result.rstatus;

Answer 2

尝试如下，

var user_id = response.data.user_id,
   auth_token = response.data.auth_token,
   errorcode = response.result.errorcode,
   messages = response.result.messages,
   rstatus = response.result.rstatus;
