If I do an AJAX post with jQuery that looks like

 $.post('MyApp/GetPostResult.json', function(data) {

    // what goes here?

 });

and the result looks like

{

    HasCallback: true,

    Callback: function(){ alert('I came from the server'); }

};

Then how do I call the Callback function? Can I just write if(data.HasCallback){data.Callback();} ?

This should work:

function(data) {

  if(data.HasCallback) {

    eval(data.Callback);

  }

}

Edit: Didn't look quite carefully enough. If you're indeed getting the function() { ... } text, then you need to eval(data.Callback + ()).
