[jQuery] Re: how to add callback in the $.ajax ?

[Adwin Wijaya]

nope, i want  to return as json.

price was there because i was logging into console. just for
debugging :) and i will do the calculation after it return the value.

I tried using async:false

and the result still undefined

function getGoodsDetail(id){
    $.ajax({
        type: "POST",
        url : "/goods/detail/",
        data : "id="+id,
        dataType: "json",
        async:false,
        success : function(data){
            return data ;
        }
    });
}

var x = getGoodsDetail(10);

any idea ?
 I think i need to have callback so that I can return the value ...
just like in $.post and $.get.

is it possible ?
thanks
