yet another question:
I would like to mask a data entry and I found this at http://digitalbush.com/projects/

<script src="jquery.js" type="text/javascript"></script>
<script src="jquery.maskedinput.js" type="text/javascript"></script>
Next, call the mask function for those items you wish to have masked.
jQuery(function($){
   $("#date").mask("99/99/9999",{placeholder:"mm/dd/yyyy"});
   $("#phone").mask("(999) 999-9999");
   $("#tin").mask("99-9999999");
   $("#ssn").mask("999-99-9999");
});

but I have no idea what to do with it.
how does on hook this up in html

ps: forgive me I am brand new to this js stuff
