将JSON反序列化为JavaScript对象 [英] Deserializing a JSON into a JavaScript object

问题描述

我在Java服务器应用程序中有一个使用AJAX访问的字符串。它看起来如下所示：

I have a string in a Java server application that is accessed using AJAX. It looks something like the following:

var json = [{
    "adjacencies": [
        {
          "nodeTo": "graphnode2",
          "nodeFrom": "graphnode1",
          "data": {
            "$color": "#557EAA"
          }
        }
    ],
    "data": {
      "$color": "#EBB056",
      "$type": "triangle",
      "$dim": 9
    },
    "id": "graphnode1",
    "name": "graphnode1"
},{
    "adjacencies": [],
    "data": {
      "$color": "#EBB056",
      "$type": "triangle",
      "$dim": 9
    },
    "id": "graphnode2",
    "name": "graphnode2"
}];

当从服务器中提取字符串时，有一种简单的方法可以将其变为活动的JavaScript对象（或数组）？或者我是否必须手动拆分字符串并手动构建我的对象？

When the string gets pulled from the server, is there an easy way to turn this into a living JavaScript object (or array)? Or do I have to manually split the string and build my object manually?

推荐答案

现代浏览器支持 JSON .parse（）。

var arr_from_json = JSON.parse( json_string );

在没有的浏览器中，您可以包含 json2 库。

In browsers that don't, you can include the json2 library.
