Masked input plugin for the jQuery

This is a masked input plugin for the jQuery javascript library. It allows a user to more easily enter fixed width input where you would like them to enter the data in a certain format (dates,phone numbers, etc). It has been tested on Internet Explorer, Firefox, Safari, Opera, and Chrome. A mask is defined by a format made up of mask literals and mask definitions. Any character not in the definitions list below is considered a mask literal. Mask literals will be automatically entered for the user as they type and will not be able to be removed by the user.The following mask definitions are predefined:
a - Represents an alpha character (A-Z,a-z)
9 - Represents a numeric character (0-9)
* - Represents an alphanumeric character (A-Z,a-z,0-9)

Using jQuery validate plugin with CKEditor

Just a quick post (mostly for my own reference!) on using the jQuery validate plugin to check that a CKEditor instance has content. The problem is that CKEditor replaces the HTML textarea tag with a WYSIWYG editor, the jQuery validate plugin validates against the textarea, not the contents of the WYSIWYG editor.

Strip special characters with jQuery form validation

i was using a jquery form validation plugin and it was so easy in validating a form. I was stuck in a scenario where i want users to register userID and i dont want them to enter special characters like dots and just want them to enter alphabets, number and underscore in the username.

I went through the documentation of the plugin and there was no such methods to strip the special characters in the plugin.
Finally, i somehow got hold of the code that does the job through regular expression regex that checks for only numbers and a-z

Credit card validation extension for jQuery Validation plugin

Here's an improved credit card validation extension for the jQuery Validation plugin. This lets you pass the credit card type into the validation routine, which allows it to do card type specific checks for prefix of the card number and number of digits. This extension includes the mod-10 check (based on the Luhn Algorithm) that is used in the core creditcard validation routine. As an extra bonus, it will ignore spaces and dashes in the card number. This code was ported from this credit card validation routine by John Gardner, with some minor tweaks and additions.

Usage

Here is an overview of one way to use the creditcard2 extension. There are a number of ways you can wire up validation rules with the jQuery Validation plugin, so it helps if you already understand how that plugin generally works (settings, rules, styling, error messages, etc).
