Javascript:Detect events in input boxes?

[Anon]

Hi!

I've got a Javascript/DHTML question - hope it's ok that I post it here?

I need to detect two events, but I don't know how (and I'm not very familiar with Javascript and events):

1. If a user enters the number "1" into one of my input boxes.
2. If a user checks or unchecks a check-box.

Both boxes are input-boxes in a form. I need to implement this on client-side, that is why I don't use php for this. I want some hide/unhide some spans/divs exactly when/after the user has checked/entered value, without refreshing/reloading the page.

Do any of you know how/if I can do this?

Thanks,
Torbjørn

I forgot one thing...:

I also want to detect if a user changes the "1"-value to something else, in the input box (1).

Guess you could use something like

window.event.Element, and search for some value of Element...

Can't help you more...sorry
