Making your site Great!

Javasript

Javascript allows a visitor to your webpage interact with it, to change it or for it to perform certain tasks. Javascript was used to create the rollover images already described.
When a visitor comes to your site a series of 'events' happen. An event is basically a message from your browser to indicate that a visitor has done something.
Lets use the rollover image as an example. When the visitor places their curser over the rollover image, the event (message) OnMouseOver is created by the browser. The browser then checks to see if it has any javascript that is supposed to be called when that event is generated.


Forms

These are used to gather information from visitors to your site. They consists of a number of fields which can be filled in by visitors and when submitted the information is sent to a cgi, php, asp, cfm or jsp script. These scripts process the information and can run a variety of server side tasks. There are many of these scripts available freely on the web, although for more powerful software such as affiliate software you can expect to pay a reasonable fee. View the section below on downloading such software.
