.getJson不填充陣列

Question

我有以下代碼：

$(document).ready(function() { 
    $.getJSON('../includes/_quiz.php?class_id=163&course_id=183',function(data){ 
     $.each(data,function(k,v){ 
      questions[k] = v.question; 
      answers[k*4] = v.ansO; 
      answers[k*4+1] = v.ansT; 
      answers[k*4+2] = v.ansTh; 
      answers[k*4+3] = v.ansF; 
      }); 

     //html 
     }); 
    }); 

問題陣列沒有被填滿，然而，當我調試，我得到這樣的結果： 當我請求的頁面在瀏覽器我收到相同的結果是：

我調試的代碼，發現它不進入裏面，它直接移動到年底

之前，我做了一些modificat離子代碼，數組填充， 可能是什麼問題？

Answer 1

如果JSON文件包含語法錯誤，請求通常會失敗默默。因此，添加.error方法並檢查解析json時是否有任何錯誤。

// Assign handlers immediately after making the request, 
// and remember the jqxhr object for this request 
var jqxhr = $.getJSON("example.json", function() { 
    alert("success"); 
}) 
.success(function() { alert("second success"); }) 
.error(function() { alert("error"); }) 
.complete(function() { alert("complete"); });

請數據分配給一個變量

瓦爾結果=數據

你只寫像

警報（結果[0] .questions）

您正在獲取數組格式但未分配給變量。 首先分配給變量
