Question

I am trying to get the response from ajax call and save it in another value but wont work
this is my code

x='go'
$.post("someurl",function(data){
    x=data;
})
alert(x)//go

or this
jsFiddle

I am looking for a solution for this problem without storing the value in any HTML container

Answer 1

$.post is asynchronous – the callback will be executed later, after your alert(x) line.

Try:

$.post("someurl",function(data){
    x=data;
    alert(x)
})

(No, there’s no other way around this – you’ll have to restructure your code accordingly. Don’t be tempted to try setting async to false, or you’ll end up with bigger problems).
