78 Javascript DHTML Events

*** Updated - 103 Javascript Events ***

We all know about the onfocus event but what about the onfocusin and onfocusout events? Sure there's the onunload event, but what of the onbeforeunload event? For those you who have never heard of these before, now you can. Below is a full list of javascript events courtesy of the MSDN library.

It's also worth noting that the majority of these events only work in Internet Explorer. If you see a W3C Standard note next to an event, however, it means that just about all major browsers support this event.
