如何模拟xmlhttprequest并获取json响应？

这里答案：

HTTP/1.1 200 OK
Server: nginx/1.1.7
Date: Fri, 06 Jan 2012 10:50:36 GMT
Content-Type: application/x-javascript; charset=utf-8
Transfer-Encoding: chunked
Connection: keep-alive
Vary: Accept-Encoding, Accept-Language,Cookie
Content-Language: ru
Content-Encoding: gzip

此处请求：

GET /community/accounts/?type=table&_=1325847040822&offset=0&limit=25&order_by=name&search=Danzanus&echo=2&id=accounts_index HTTP/1.1

网站为http://worldoftanks.com/community/accounts/

带参数的GET请求： http://worldoftanks.ru/community/accounts/?type=table&_=1325847040822&offset=0&limit=25&order_by=name&search=Danzanus&echo=2&id=accounts_index

我需要获取带有用户个人资料链接的搜索结果。 Firebug（FF插件）显示了这个答案：

{"request_data":{"items":[{"account_url":"/community/accounts/4213704-Danzanus/","abbreviation":"","exp":514111,"name":"Danzanus","clan_url":"","owner":null,"wins":816,"created_at":"2011-11-29","id":4213704,"battles":1626}],"total_count":0,"filtered_count":1,"offset":0,"echo":2},"result":"success"}

我只需要“account_url”。

此代码返回200 OK但是答案为空：

 $.get("http://worldoftanks.ru/community/accounts", { type: "table", _: 1325811501451, offset: "0", limit: "25", order_by: "name", search: "Danzanus", echo: "3", id: "accounts_index" },
   function (data) {
       alert("Data Loaded: " + data);}

谢谢。

如果这是webservice返回的响应，你可以解析XHR响应（例如在jQuery onsuccess方法中，这是在Ajax调用之后调用的）并获取account_url。否则，如果要重新创建响应客户端，则应创建表示响应的JS对象，然后将其转换为JSON表示形式。然后，您可以从客户端脚本中调用返回JSON的方法（在本例中为 getMyObjAsJSON ）。

这是一个示例

function getMyObj() {
var firstname = 'Michael'
var lastname = 'Jordan'    
return  { FirstName: firstname, LastName: lastname };}  

function getMyObjAsJSON(){
 var myObj = getMyObj();

    if (myObj == null) {
        alert("obj not created");
        return;
    }

    //it converts the object in its JSON rapresentetion
    var jsonObj = $.toJSON(myObj);
return jsonObj}
