One of the most popular usages of JavaScript is to create a drop down menu. This tutorial will show you how to make one.

This tutorial contains a java script code which is a simple e-mail address validation script. While it is not too sophisticated, it does provide the basic validation function.

Takes an email address and returns just the domain - the stuff after the "@" sign. We've put it together with a simple WHOIS query, neat!

This is an e-mail address validation function. It allows the usual user@domain syntax, but in addition allows user@[ip] format as well as "User with Spaces"@domain or [ip], all of which are legal syntax, according to W3C. It also checks that the user hasn't done anything silly like having multiple @'s or continuous .'s in the address (e.g. jim@b@c.com and jim@c..b.co.uk)

Visitors sometimes include their email address inside the message field when they fill out forms. To deal with this, this script parses through the string and uses a Regular Expression to find then return a comma-separated list of the valid email addresses it finds.

Here's a clever way to prevent email address collecting "robots" from grabbing your email address while still making your address available to your visitors.

This script displays a floating layer that moves with the page, which contains an "email-this-link" script. The e-mail script automatically captures the URL of the page and opens up your e- mail with all the pertinent information.
