So here’s the JS

$(document).ready(function(){

$('[rel=tooltip]').bind('mouseover', function(){

 if ($(this).hasClass('ajax')) {
 var ajax = $(this).attr('ajax'); 

  $.get(ajax,
  function(theMessage){
$('<div class="tooltip">'  + theMessage + '</div>').appendTo('body').fadeIn('fast');});

}else{

var theMessage = $(this).attr('content');
     $('<div class="tooltip">' + theMessage + '</div>').appendTo('body').fadeIn('fast');
  }

  $(this).bind('mousemove', function(e){
   $('div.tooltip').css({
    'top': e.pageY - ($('div.tooltip').height() / 2) - 5,
    'left': e.pageX + 15
   });
  });
 }).bind('mouseout', function(){
  $('div.tooltip').fadeOut('fast', function(){
   $(this).remove();
  });
 });
   });

The HTML

The following combination of attributes can be added to any link to create a tooltip.

• rel=”tooltip” | this enables the link as a tooltip without this no tooltip would be show for that specific link
• class=”ajax” | if you want to call another page using ajax into the tooltip you need to add this class aswell as add the attribute ‘ajax’ with the link to the page you want to call
• ajax=”AJAX_URL_HERE” | this is where you specify the link to the page that you want to pull in using ajax.
• content=”Tooltip content” | this is where you put your main tooltip text including any image using regular html
