試圖學習.ajax（） - 我的json不斷拋出錯誤：「undefined」 - 我在做什麼？

我不知道爲什麼我的json對象返回undefined。在我的JSON工具中，我沒有發現任何語法錯誤，但我有一種感覺，在構建它的過程中一定有什麼問題。試圖學習.ajax（） - 我的json不斷拋出錯誤：「undefined」 - 我在做什麼？

我想開始製作一款殭屍遊戲，但對於我來說，第一步是瞭解如何將我創建的數據傳遞到前端。這是我一直希望實現的類AJAX，但我的控制檯是給我的錯誤：「未定義」

$(document).ready(function(){ 
       $.ajax({ 
        url: 'dummy_json.json', 
        data : { load : true}, 
        type: 'GET', 
        dataType: 'json', 
        timeout: 1000, 
        error: function(jqXHR, textStatus, errorThrown){ 
         console.log("HOLY SHIT ZOMBIES!"); 
         console.log(textStatus + " is " + errorThrown); 
        }, 
        success: function(data){ 
         $("body").append(data); // really basic append, more to come. 
        } 
       }); 
      });

及以下的dummy_json.json文件，其中包含我的手寫殭屍的內容任務數據。我想從頭開始做這件事，這樣我就可以很好地學習json。最終我會寫的PHP從數據庫中提取這個，並轉換爲json的視圖消耗：

感謝您的代碼。錯誤說的究竟是什麼？它在你的代碼中發生了什麼？ – Madbreaks

所以我使用FF和Chrome。「errorThrown」的值是「未定義的」 - 基本上它認爲整個json對象是未定義的......我可以通過以下方式糾正這一點：'1。我括住了整個陣列。 2.我括住了每個「bulletinquest」數組的全部內容3.我用雙引號將id包裹起來。**現在我遇到的問題是，當我嘗試訪問嵌套的_items_數組時 - 控制檯認爲它是undefined！** – user1809836

這是無效的JSON。你需要用方括號中的整個事情，使一個數組：

[ { id : 0, ... }, 
    { id: 1, ... }, 
    ... 
]

注意，要檢查JSON是有效的，有大量的在線工具，可以幫助（例如，JSONLint）。（你會在那裏看到，有效的JSON在技術上要求把鑰匙（id等）用雙引號括起來。）

嗚呼！它現在有效。我根據您的建議做了幾件事： 1.我括住了整個陣列。 2.我括住了每個「bulletinquest」數組的所有內容 3.我用雙引號將id包裹起來。成功。謝謝dbaseman！ – user1809836

鍵是不允許在json中具有相同的值EVER？我不斷收到「data [index] .bulletinrequest.items未定義。」嗯... – user1809836

@ user1809836你不能在同一級重複鍵... – McGarnagle

試圖學習.ajax（） - 我的json不斷拋出錯誤：「undefined」 - 我在做什麼？
