顯示JSON數組的問題

你能幫我弄清楚爲什麼我得到「未定義」而不是價值。顯示JSON數組的問題

因爲它是清楚地看到，我遇到了麻煩從陣列中的數據，在螢火我得到這個作爲響應....

{"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":[]}]}

這是指我的JavaScript文件中的代碼 http://pastebin.com/gPaEAKim

我得到的視圖的快照。

只是要在安全方面......這是當我從控制器

哪些變量在代碼中未定義？ – 2012-01-16 14:40:34

我的猜測是它在兩個'each（）'循環中都使用'email'有關。嘗試給他們不同的名字。 – jprofitt 2012-01-16 14:41:35

如果您data變種在你的JS代碼是調試它像數組的樣子JSON響應的全部，那麼你的工作一個級別太高，而內循環工作2個水平過高：

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

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

爲您代碼現在代表，內部循環的email也覆蓋你的外部循環。

不想推我的運氣，但我可以請你詳細說明這一點。我不太明白。 – 2012-01-16 14:53:48

您的php腳本正在發送一個json對象，這可能是您發佈的firebug轉儲。這意味着'data'對象的頂層是'data.response'和'data.status'。你的第一個JS .each循環正在處理'data'本身，所以你會得到'response'和'status'值。你的第二個.each循環再次作用於'data'作爲一個整體，並將得到相同的兩個鍵。 – 2012-01-16 17:29:25

謝謝你解釋！ – 2012-01-16 18:02:26
