Question

我正在开发一个关于Django框架的网站，它返回一个json响应，用于使用jquery数据表。数据表需要输入为javascript对象或arrys数组，所以我需要在服务器端或客户端将其转换为javascript对象或数组。

以下是数据表的相关文档。

Answer 1

大多数浏览器都支持JSON.parse()，这是在ECMA-262第5版（JS所基于的规范）中定义的。它的用法很简单：

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

alert(obj.count);

对于没有的浏览器，您可以使用json2.js实现它。

Answer 2

在客户端上，您可以使用：

JSON.parse(json)

“json”是JSON字符串。

或者，如果您还使用jQuery来执行AJAX请求，它将在“success”处理程序中为您执行反序列化。

        $.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

        }
    });

Json到Javascript对象或Array
