Answer 1

function ChangeDasPanel(controllerPath, postParams, f) {
  $.get(
    controllerPath, 
    postParams, 
    function(returnValue) {
      var $DasSpace = $('#DasSpace');
      $DasSpace.hide(
        "slide", { direction: "right" }, 1000, 
        function() {
          $DasSpace.contents().remove();
          $DasSpace.append(returnValue).css("display", "block");
          $DasSpace.show("slide", { direction: "right" }, 1000);
        }
      );
      if (typeof f == "function") f(); else alert('meh');
    }
  );
};

You can pass functions like any other object in JavaScript. Passing in a callback function is straight-forward, you even do it yourself in the $.post() call.

You can decide whether you want to have your callback called as part of the $.post() callback or on its own.
