Json to Javascript對象或數組

Question

我正在Django框架上開發一個網站，它返回一個使用jQuery數據表的json響應。 Datatable需要輸入爲javascript對象或arrys數組，所以我需要將其在服務器端或客戶端轉換爲javascript對象或數組。

這是數據表的相關文檔。

Answer 1

大多數瀏覽器支持JSON.parse()，這是在ECMA-262第5版（即JS是基於本說明書中）所定義。它的用法很簡單：

var json = '{"result":true,"count":1}', 
obj = JSON.parse(json); 

alert(obj.count); 

對於那些不能使用json2.js來實現的瀏覽器。

在客戶端，你可以使用：

JSON.parse(json) 

「JSON」 是JSON字符串。

或者，如果您還使用jQuery來執行AJAX請求，它將在「成功」處理程序中爲您執行反序列化。

 $.ajax({ 
     type: "GET", 
     url: "your url", 
     dataType: "json", 
     contentType: "application/json", 
     success: function (e) { 
      // the value of "e" should be a javascript object or array depending on the response 

     } 
    });
