Many of us would like to have Scripts or html pages which could be run OFFLINE on the clients PC when they are NOT connected to the internet.
API Declarations
//
// Returns:This example just uses an ALERT BOX when the Browser is offline. you
// can replace that with any logic you wish
// , or just inform the person that they mu
// st be online to use your Page or Script.
//
//
// Assumes:Not only does this tell you i
// f the Client PC is ONLINE or OFFLINE it
// also tells you if the Client PC is Dial-
// up or High-Speed. This means you could a
// lso use this to determine Download optio
// ns if your visitor is accessing your sit
// e via a Slow speed dial-up line you coul
// d re-direct to pages with less images ju
// st for them so that pages would load fas
// ter for dial-up visitors. Neat huh.
No alert was added for this check however you can see that could be done very easily ;-)
//
// Side Effects:Joy to those of use whom
// needed a way to take a diffenert path su
// ch as getting Gifs, scripts from a direc
// tory on the users hard drive when the us
// er wishes to use our tools or applicatio
// ns offline and the HTML is pointing to a
// WEB Site for scripts of images.
