 document.capture
Anyone familiar with NS and events should already know how to do this
one:
document.captureEvents(Event.MOUSEDOWN);
document.onmousedown=function(event) {
alert(event.type) // "mousedown"
}
If you don't feel like passing an argument, once again:
document.captureEvents(Event.MOUSEDOWN);
document.onmousedown=function() {
alert(arguments[0].type) // "mousedown"
}
As is apparent, NS force feeds the event object as an argument, whether
you want it or not. Unlike the previous examples of using
arguments.callee.caller, no wrapper function is involved here. Nice
and simple.
addEventListener
This only applies to NS6 and other Gecko-based browsers, such as
Mozilla, K-meleon, and Galeon.
document.addEventListener('mousedown',doSomething,false);
The event is passed exactly the same as with captureEvents:
function doSomething(event) {
alert(event.type) // "mousedown"
}
Is the same as:
function doSomething() {
alert(arguments[0].type) // "mousedown"
}
Once again, no wrapper function involved, and the event argument is
passed on, like it or not.
