Site is http://worldoftanks.com/community/accounts/

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

I need get result of search with link to user profile. Firebug(FF plugin) show this answer:

{"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"}

I need only "account_url".

this code return 200 OK but answer is null:

 $.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);}

Thank You.

If that is the response returned by the webservice you can just parse the XHR response (in the jQuery onsuccess method for instance, this is called after the Ajax call) and get the account_url. Otherwise, if you want to recreate the response client side you should create your JS object representing the response and then convert it in it's JSON representation. You can then call the method returning JSON (in this case getMyObjAsJSON ) from your client script.

Here's a sample

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}
