<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.
