Java EE (Java Enterprise Edition) General Discussion

I'm asking this question here as I could not find the needed help elsewhere .

I don't know how to pass the key pressed in the function on OnKeyPress event .

I'm trying the following :

<input type="text" name="a" onKeyPress="check();">

I want to pass the key presses in the check function .
How to collect the key pressed in the function check ?

Thanks.
