Keypress

Hamish · Nov 10, 2004

I am trying to detect the up and down keys on a key press function, but they
do not seem to generate a keypress call. Is there another event generated
when these keys are pressed

Thanks.

PS Apologies if this appears as a double post, but the news server I used
originally does not seem to propagate most other news servers.

document.onkeypress will return your basic functional text keyboard. When
you press an alphanumeric key you will get it's lower case value. When you
press shift and an alphanumeric key you get the upper case value or in the
case of numbers the corresponding shifted characters. If you need to trap
other key events like the up/down arrows or the backspace etc you need
onmousedown or onmouseup and the correct browser feature detection since
there is no standard for DOM Level 2 AIUII. Hope this link helps.
