Jquery sistemde ekli olmalı. basit olarak aşağıdaki kodu head tagına koyabilirsin.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js"></script>
Hepsi toplu olarak:
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function (){
$("a").each(function(e) {
var title = $(this).attr('title');
$(this).mouseover( function() { $(this).attr('title',''); }).mouseout( function() { $(this).attr('title', title); });});
});
</script>
</head>
<body>
<a href="#" title="Deneme">deneme link</a>
</body>
</html>
