Make AJAX “get” function synchronous / how to get the result?

Question

I\'m experiencing a problem of $.get function. The url contains JSON

my code:

 xyz = null

    $.get(\'http://www.someurl.c         


        

Answer 1

get is a shortcut. You can do the same, but synchronous, using:

var xyz = null


$.ajax({ url: 'http://www.someurl.com/123=json', 
         async: false,
         dataType: 'json',
         success: function(data) {
              xyz = data.positions[0].latitude;
            }
        });


alert(xyz);

You'll have to declare the xyz variable before the ajax call, though.
