TQ's Field Validator Demo

This ASP.Net Web Forms app is a simple demo to demonstrate how jQuery-AJAX can be used with a .Net Web Service (.asmx) to validate form data.

The source code for this demo can be found on GitHub. At some point I will add some additional documentation to the README file, but for now, this page is as good as it gets.

For the purposes of this demo, the validation web service will check to ensure the following are true or an error will be displayed:

• First Name must be less than 50 characters
• Last Name is required
• Last Name must be less than 50 characters
• E-mail must be less than 50 characters
• E-mail must be a valid e-mail address
• Phone number must be less than 50 characters
• Phone number must be valid in the US or Canada

First Name:
Last Name:
E-mail:
Phone Number:

WebService.cs utilizes the static methods in the Utils class to evaluate each field. The web service can be easily customized to validate for different field lengths or to utilize other Utils methods.

The error messages are diplayed as HTML ordered list items. One thing I would like to add at some point: mark the failed fields with an indicator. I can't think if an easy way to do that, so suggestions are welcome.
