Why is this jquery method not returning SELECTED value?

Question

My jquery method WILL not return value "Selected". My alert shows that the value is retrived from database. But if I write data=GetSelected(); it is undefined...

 function GetSelected()
 {
     $.ajax({
         type: 'GET',
         url: '/api/machine/',
         dataType: "JSON",
         data: "data",
         error: function (error) { },
         success: function (data)
         {
            $.each(data, function (i, data)
            {
                 if (data.machinenumber == 2)
                {       
                     selected = data.selected;
                     alert('Selected er: ' + selected)
                     return selected;
                 };

            });

         } 
     }); 
 }

The return statement belongs to the function(i, data) header in the for-each loop, not the function (data) header that is getting executed on success. Basically the values gets returns to the outer function and ignored there.

Also the logic is asynchronous, so the above also happens long after the `GetSelected()` function has exited. – Rory McCrossan Mar 06 '20 at 21:31
Like that? $.each(function (i, data)...Did not work. – Peter Gade Carstensen Mar 06 '20 at 21:37
Oh..I remenber something about a callback function inside my function – Peter Gade Carstensen Mar 06 '20 at 21:39
