Convert data send from server through POST/GET to jquery function

How to convert data to Integer which came with GET/POST from server to jquery function.

1) Those lines belong to server , and they are send to jquery script

line = json.dumps([1])
       return line

2) This little code returns fetched result as json from the server , well at least i think its a json objects.

function lol() {
   $.getJSON("http://help.me.plz:12345/test",function(result){
       return result
   });
}

3) So how do i convert value which comes from lol() to int ?

while (data.length < totalPoints) {
  开发者_开发百科          var prev = data.length > 0 ? data[data.length - 1] : 50;
            var y = lol();
            data.push(y);

Debug : Thats what i basically get from firebug

Headers Response HTML [1] <--- SO it is send

Response Headersview source
Date    Tue, 03 May 2011 09:11:05 GMT
Content-Length  3
Content-Type    text/html
Server  TwistedWeb/8.1.0

Its a dump of the last list i need to get, but i get undefined instead of numbers.

[[0, undefined], [1, undefined], [2, undefined]  ....

I tried to fetch content with $.ajax() , i tried to use parseInt() on lol , basically on everything .... I am kind of lost :D I am sure it is easy . Yet my stupidity makes me ask for help ....

Ajax calls are asynchronous by default, so you can't return the value in a function. You'd have to do something like this:

$.getJSON("http://help.me.plz:12345/test", function(result){
  var y = result; //Now we don't call lol()
  while (data.length < totalPoints) {
            var prev = data.length > 0 ? data[data.length - 1] : 50;
            data.push(y);
    ...
  }     
});

Hope this helps. Cheers
