Definition and Usage
The onunload event occurs once a page has unloaded (or the browser window has been closed).
onunload occurs when the user navigates away from the page (by clicking on a link, submitting a form, closing the browser window, etc.).
Note: The onunload event is also triggered when a user reloads the page (+ the onload event).
Note: Due to different browser settings, this event may now always work as exepcted.
Note: The addEventListener() method is not supported in Internet Explorer 8 and earlier versions.
