In JavaScript:
object.onoffline = 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.
<!DOCTYPE html> <html> <body> <p id="demo"></p> <script> document.getElementsByTagName("BODY")[0].ononline = function() {onFunction()}; document.getElementsByTagName("BODY")[0].onoffline = function() {offFunction()}; function onFunction() {// w w w . j a va 2s.com document.getElementById("demo").innerHTML = "Your browser is working online."; } function offFunction() { document.getElementById("demo").innerHTML = "Your browser is working offline."; } </script> </body> </html>
