Secret Access

You go to a web page without a form or prompt indicating it might double as a secret access to another web page. You go ahead and type a certain sequence of characters on your keyboard. If you get it right, you are redirected to a secret web page.

Controlling Checkboxes with JavaScript

Sometimes it's desirable to control whether or not certain checkboxes are checked, or to do something depending on which ones are checked. Although CGI scripts can do their own error checking and display messages to the form user as needed, letting JavaScript do some of the preliminary checks can be faster and less frustrating for the form user.

Browser-Correct Download Instructions

Learning to Function and Loop

HTML is boringly static, it's rigid, and, is least interactive. DHTML makes it dynamic and responsive. Now, DHTML is not another of those nerdy technologies, it's just that when we come up with a concoction of HTML + JavaScript (or VBScript), the guys call it DHTML just to sound cool. DHTML stands for, Dynamic Hyper Text Markup Language (ok, so now you can actually figure out what's all with HTML).
