显示JSON数组时出现问题

Question

您能否帮我弄清楚为什么我得到“未定义”而不是值。

显而易见，我在从数组中获取数据时遇到了麻烦，在萤火虫中，我将其作为响应...。

{"status":"success",
 "response":[
    {"email":
        {"email":"xxxxx@iing.mxl.uabc.mx",
         "valid":"1",
         "reason":null,
         "confirmed_at":"0000-00-00 00:00:00",
         "contact_email":"1",
         "login_email":"1",
         "users_id":"6375"},
     "history":[
        {"contactRole":"Non Classified Lead with History",
         "contactProject":"2082",
         "contactBrand":"B"},
        {"contactRole":"co Author",
         "contactProject":"32",
         "contactBrand":"B"},
        {"contactRole":"co Author",
         "contactProject":"176",
         "contactBrand":"B"},
        {"contactRole":"co Author",
         "contactProject":"582",
         "contactBrand":"B"},
        {"contactRole":"co Author",
         "contactProject":"1858",
         "contactBrand":"B"},
        {"contactRole":"Author",
         "contactProject":"12",
         "contactBrand":"J"},
        {"contactRole":"Editor",
         "contactProject":"176",
         "contactBrand":"B"}]},
    {"email":
        {"email":"xxxxx@hotmail.com",
         "valid":"1",
         "reason":null,
         "confirmed_at":"0000-00-00 00:00:00",
         "contact_email":"0",
         "login_email":"0",
         "users_id":"6375"},
     "history":[]}]}

我得到的视图的快照。

出于安全考虑...这就是我从控制器调试数组时的样子

Answer 1

如果您的JS代码中的data变量是整个JSON响应，则您的工作水平太高了，而内部循环的工作水平又太高了2级：

$.each(data['response'], function(i, email) { 
           ^^^^^^^^^^^^--- missing this

      $.each(email, function(ii, ...)) {

按照您的代码现在的样子，内循环的email也会被外循环的email覆盖。
