Suggesting input - a jQuery snippet Graceful degrading javascript

Today I’d like to share with you a snippet that simply uses the ‘title’ value of an input to make a suggestion. It degrades nicely, also users with Javascript turned off are able to get the hint, by hovering over.

 
$('input[title]')
    .val(
      function(i,value) {
        return value == "" ? $(this).attr("title") : value;
      })
    .focus(
      function() {
        if ($(this).attr("title") == $(this).val()) $(this).val(""); 
      }
    );
    // added: don't submit the suggested values
    $('form').submit(function() {
      $('input[title]').val(
        function(i,value) {
          return value == $(this).attr("title") ? "" : value;
        }
      );
      
    });

For optimal userfriendlyness, make the suggested input a little less dark than the user filled in ones.

BTW. It assumes you are already using the jQuery library.
