[Javascript] onclick and functions

[Rakesh Pai]

Didn't try this yet, but I'd think the way you are registering the
event is wrong. You cannot pass a function with arguments as a handler
for an event.

Try this instead:

a.onclick = function() { test1(1); }
b.onclick = test2;

I might be wrong though.

That said, using a addEvent function is a cleaner way to attach
handlers to an event. Do a google search for it.
