I just did a minimal ajax process and it doesn't work! the onkeyup demo in
the book works when i try though, but onclick just messes with me... i've a
few places in my application where onchange also triggers an ajax function
but idk, onclick just doesn't seem to work anywhere i try it. must it be in
a form? is it specific to only some elements? what am i missing... :/
