2. function validate_manager(manager_id) {
4. var a = $.ajax({ 
5. type: "POST",
6. dataType:"JSON",
7. data: {
8. ajaxCall: 1,
9. manager_id: manager_id
10. },
11. url: "/system/php/ajx_check_username.php",
12. async: false   // Wait for completion ......
13. });
15. a.done(function(data) {
16. console.log(data);
17. return data;
18. });
20. a.fail(function(response) {
21. var data = {
22. success: false,
23. error_message: response.status+':'+response.statusText
24. };
25. console.log(data);
26.     return data;
27.   });
28. }

The console.log is outputting what I want, but the calling function gets 'undefined',

Sure this is simple, but its breaking me now!!
