Animate placeholder text, is it possible?

Animate placeholder text, is it possible?

Hi all, 

Been pondering and trying to get some text that is replaced by another bit of text on hover and was wondering if it is possible to animate the change. 

  1. $(function() {
  2.       var placeholdertext = "test"; 
  3.       var Placetext = new Array();
  4.  
  5.       Placetext[0] = "test this"; 
  6.       $("#FALA").hover(function() { 
  7.             $(this).text(Placetext[0]);
  8.                   }, function() { 
  9.             $(this).text(placeholdertext);
  10.       }); 
  11. }); 

I take it this is also the best way to do it? 


Also this is what I've tried but no success.
  1. $(this).stop().animate({text(placeholdertext)}, 300);

Cheers for any help!
