Attributes for <INPUT ...>
onKeyUp = "script command(s)"
onKeyDown = "script command(s)"
onKeyDown is triggered when the user presses down on a key while
the cursor is in the input field.
onKeyUp is triggered when the
the key goes up again. For example, the following code puts
"down!" in the status bar when the key goes down, and
"up!" when the key goes up:
| this code |
produces this |
<INPUT
NAME="realname"
onKeyDown="window.status='down!'"
onKeyUp="window.status='up!'">
|

onKeyDown and onKeyUp represent the component
actions of pressing a key. They cannot be cancelled. In most situations where you
might consider using onKeyDown or onKeyUp you
will probably find that onKeyPress is more useful.
onKeyPress represents the entire keystroke and can cancel the
keystroke.
