Javascript DOM ononline Event via ononline function

Introduction

In JavaScript: 

object.ononline = function(){
       myScript};

This example uses the HTML DOM to assign an "ononline" and "onoffline" event to a body element.

Open the File menu and click on "Work Offline" to toggle between working online and offline.

The ononline and onoffline events are supported in Firefox.
