Email me at: milhous@paradise.net.nz ## ## ## ## ## #################################################### #################################################### The code is written entirely in HTML and Java Script. It functions exactly the same on either Internet Explorer or Netscape. This program represents a basic shell for an e-shop. It can easily be extened by adding extra pages, and extra products to each page. There is really no maximum to the number of products you can display with this site, although it will begin to become more unmanagable as the number goes over a couple of a hundred. All processing takes place on the users computer. The server is only used to receive the order form once the user has finished their shopping. All functions are commented. Also the HTML representing Product One on Page One is commented and explains exactly how to add a new product to a page. */ /* --------------------------------------------------------------------------------- This function is used to create instances of products. Each product must be represented by an object in the following form. The parameters are all self- explainatory - the PRICE of the product - the NAME of the product - the URL of the product on your site - the ID of the product. The product ID is essencial because this is sent back to you rather than the name of the product.*/ function product(price, name, isbn, location, id) { this.price = price; this.name = name; this.isbn = isbn; this.location = location; this.id = id; } /* -------------------------------------------------------------------------------------------- This code creates instances of the nine demo products on this site.
