Re: question about javascript and textboxes for Pros

Now *that's* interesting! I take it you would write an
event handler for the onkeypress event of this
textbox?

You lost me in the part about appending to an
accumulating string. Why not just use the the string
in
textbox.value?

Just for kicks I wrote this little script that does
something when the user takes more than half a second
between keystrokes following the first keystroke. Is
this the idea, sort of?

<script language="javascript1.2">
var then, now;
function startTimer(string) {
	var diff;
	if (now) { then = now; }
	now = new Date();
	if (then) {  diff = (parseInt(now - then));}
	if (diff > 500) { 
		alert("more than .5 sec, so do something with " +
string); 
		then = 0; now = 0;
	}
}
</script>
