如何從json引用未命名的數組

Question

我從服務器回來了：

{"Message":"The request is invalid.","ModelState":{"":["Name greg@gmail.com is already taken.","Email 'greg@gmail.com' is already taken."]}}

如何在JS中引用數組的第一項？ 調試器告訴我ModelState是一個對象，但似乎沒有數組的名稱。

Answer 1

var jsonString = {"Message":"The request is invalid.","ModelState":{"":["Name greg@gmail.com is already taken.","Email 'greg@gmail.com' is already taken."]}};

console.log(jsonString.ModelState[''][0]);

Answer 2

如果test = {“消息”：“請求無效。”，“ModelState”：{“”：[“名稱greg@gmail.com已被采用。”，“電子郵件'greg@gmail.com'已被采用。“]}}

然后你的數組在測試['ModelState'] [“”]
