Ajax, JSON + variable

Ajax, JSON + variable

Hello,

well i got a problem with using JSON.

My code looks like this:

  1. $(function()
    {


            $.ajax({
                    type:'GET',
                    url: url,
                    data:"format=json&id=123",
                    success:function(data) {
                            alert(data); // doesn't work
                    },
                    dataType:'jsonp'
            });









    });
     



The URL is an external one.
The answer looks something like this:

  1. yasearch({"q":"uboot","f":["k"],"r":[["uboote"],["uboot chat"],["uboot
    pc spiel"],["uboot simulation"],["modell uboot"],["uboot hamburg"],
    ["uboot museum"],["atom-uboot"],["uboot ping"],["rc uboot"]]})



I always get this error msg in firebug:
yasearch is not defined


I tried to define it in any way but it doesn't seem to work. I use
JSON for the first time now and don't know how to get an useable
answer.



I hope someone can help me.
