I have some problem using the $.post function !

I wrote a function that test if a username is already used in my database.

That function must return true if the username is free and false in the other case :)

My problem is that I use the $.post function and i put the return true; and return false; in the callback function.

So it's the callback function that returns true/false instead of my function !

I d'ont know what to do :/

Here is my code :

2. function validateName()
3. {
4. $.post("ajax_is_name_used.php",
5. {name: $form_name.val()}, function(data) {
6. if (data.success == 1) {
7. $form_name.addClass("error");
8. return false; // Problem, we are in the callback function !
9. }
10. else {
11. return true; // Problem, we are in the callback function !
12. }
13. }, "json");
14. }

Thanks a lot for your help :)

Pollop.
