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

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

my code:

 xyz = null



    $.get('http://www.someurl.com/123=json', function(data) {

       var xyz = data.positions[0].latitude;

    });



alert(xyz);

//some more code using xyz variable

I know that xyz will alert a null result because the $.get is asynchronous.

So is there any way I can use the xyz outside this get function?

The real answer is NO, but you can use this:

function useXYZ(){

    alert(xyz);

}



xyz = null        



$.get('http://www.someurl.com/123=json', function(data) {

   xyz = data.positions[0].latitude;

   useXYZ();

});
