显示JSON数组的问题

你能帮我弄清楚为什么我得到“未定义”而不是价值。显示JSON数组的问题

因为它是清楚地看到，我遇到了麻烦从阵列中的数据，在萤火我得到这个作为响应....

{"status":"success", 
"response":[ 
    {"email": 
     {"email":"[email protected]", 
     "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":"[email protected]", 
     "valid":"1", 
     "reason":null, 
     "confirmed_at":"0000-00-00 00:00:00", 
     "contact_email":"0", 
     "login_email":"0", 
     "users_id":"6375"}, 
    "history":[]}]}

这是指我的JavaScript文件中的代码 http://pastebin.com/gPaEAKim

我得到的视图的快照。

只是要在安全方面......这是当我从控制器

哪些变量在代码中未定义？ – 2012-01-16 14:40:34

我的猜测是它在两个'each（）'循环中都使用'email'有关。尝试给他们不同的名字。 – jprofitt 2012-01-16 14:41:35

如果您data变种在你的JS代码是调试它像数组的样子JSON响应的全部，那么你的工作一个级别太高，而内循环工作2个水平过高：

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

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

为您代码现在代表，内部循环的email也覆盖你的外部循环。

不想推我的运气，但我可以请你详细说明这一点。我不太明白。 – 2012-01-16 14:53:48

您的php脚本正在发送一个json对象，这可能是您发布的firebug转储。这意味着'data'对象的顶层是'data.response'和'data.status'。你的第一个JS .each循环正在处理'data'本身，所以你会得到'response'和'status'值。你的第二个.each循环再次作用于'data'作为一个整体，并将得到相同的两个键。 – 2012-01-16 17:29:25

谢谢你解释！ – 2012-01-16 18:02:26
