Jquery form validation - enforcing alphanumeric

Question

Does anyone know why this validation is not working, I am trying to enforce alphanumeric input of 8-12 chars but nothing is happening, I have linked to the external jquery form validation library as you can see:

<form id="userTest"> <table> <tr> <td>Password</td><td><input type="password" id="pwd"></input></td> </tr> </table> </form>

The Jquery:

$(function(){ $("form#userTest").validate({ rules:{ pwd:{ alphanumeric: true, minlength: 8, maxlength: 12 } } }); });

you are missing the additional-methods.js file where the alpha-numeric rule is added, also you might want to add the required validation

jQuery(function ($) { $("form#userTest").validate({ rules:{ pwd:{ required: true, alphanumeric: true, minlength: 8, maxlength: 12 } } }); });

Demo: Fiddle

thanks what a stupid error on my part. I can't believe that I used to have to write my own validation code in PHP. This is so much easier.

Alan, you'll still want to do validation in PHP - Javascript is easily disabled in the user's browser!
