     With this Client side/Server side (JScript/VBScript) functions you can define a Mask for a text input field, allowing the user to enter only desired characters or string in a desired fashion. For example, to allow users to enter only phone numbers in form of "(123) 456-7890" you would define a Mask as: "(999) 999-9999". The client-side function (JScript) will not allow the user to enter any invalid character as they are typing it! Any character in a Mask that is not reserved mask character (see picture) is treated as text and copied to user input field in the right place. In a former example, the user even does not have to type brackets, space and hyphen - they will be inserted as needed. Additionally, you can use server side (VBScript) functions to mask/unmask user's entry after form submission and before you save it to DB or whatever you want to do with it.

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.

If you don't have a virus scanner, you can get one at many places on the net
