Reset input type text onfocus if value differs from default.

<script type="text/javascript">
            $(document).ready(function(){
                $("input[type=text]").focus(function(){
                    if(this.value == this.defaultValue){
                        $(this).val("");
                    }
                });
            }); 
        </script>
