Re: [Staffslug] Javascript Problem
Well fantastic. I am very grateful and shall be using your version.
But, what does this mean:
var event e || window.event;
which is what I have used as apposed to:
if (!e) var e = window.event;
your version.
I assume (!e) tests for no error(s)? and then assigns e a class like
window.event or is it just checking for any events such as onClick? I have
seen the || (or) symbol before in this sort of context. Is it another way
to get the class or status of window.event? I tried to change || to an =
sign but it did not like it.
Regards, Walter

looking in the completely wrong direction. I'll dig a bit deeper now so
maybe I will even understand why this happens.
Just beat me to it :)
This (event propagation) is a fairly common concept in GUI programming,
the details vary a lot though. The idea is to allow objects to handle
events they use and pass on the ones they don't.
Anyway, glad to help.
