Need help with textboxes

Kodiak

I am trying to write some javascript code in which you enter some text
in one text box and the text will also appear in the second text box.
For example, if I write the word "Test" both text boxes should have
the same word in them. I need to be able to see the work actually
being typed out in both text boxes as well. If I trye the letter T
then both text boxes should have the same result all the type. If I
delete the letter T then both boxes should delete the letter T and so
forth. If anyone can help with this problem I woule really appreciate
it. Here is a code sample I am using below!

<html>
<head>
<script type="text/javascript">
function checkKey()
{
txtOutput.value = txtEnterValue.value;
}
</script>
</head>

<body>

<p>Type a word.<br>
<input type="text" name="txtEnterValue" onkeypress="checkKey()"</
p>
<p>The result should appear in this box as you type.<br>
<input type="text" name="txtOutput"</p>

</body>
</html>

EDIT:

You can also call on a form by it's position in the FORMS array:
My examples are FAR from perfect.

Sorry about the typos.

That's a pretty silly requirement. Is this for a class?

Sorry Lee, but that's a pretty arrogant statement...

The fact that the OP is having trouble obtaining references to form
elements, strongly suggests that he's just starting out with
JavaScript. That doesn't mean he has to write something useful to
start with. I am sure his only goal is to create something simple, and
understand how it works, even if it serves no real purpose.

While criticism is usually welcome, it's usually only welcome when
it's helpful, and reasons as to why a particular method of doing
something may not be the best. You're comment offers absolutely no
help, and gives the impression that anything posted will put under
scrutiny, which is not what we are here to do.

So there exists a "what we are here to do"?

That certainly must be your personal conception of usenet,
that it is one gigantic helpdesk.

Iteration:

... a pretty arrogant statement

I certainly don't think it is arrogant,
and I would not use those words easily if I where you,
but I deduct I am not.

Reiteration:

>Is this for a class?

I too would like an answer to that from the OP.

While the requirement is rather silly,
it is a good subject for a home experiment in a teaching assignment.

If so, we should, I think not spoil the learning effect by doing such
experiment for him or her.

Certainly it is part of "what we are here to do". If you blindly
give every poster exactly what they ask for, without considering
why they're asking for it, and what misconceptions or ulterior
motives may lie beneath the request, you're being irresponsible.

Years of experience in this newsgroup suggests that when a poster
asks for something that's trivial and pointless, there's a very
good chance that it's a homework assignment. We shouldn't be
doing homework assignments for students. Do you disagree?

You'll notice that I didn't refuse help. They had already
received help. I simply pointed out why I suspected that it
may be a homework assignment and asked if it, in fact, is.

It may well not be. It might be an attempt at learning on their
own, in which case, more power to them, or it might be an ill-
conceived required "feature" on a web site. There might even be
a very good reason for it, but the odds seem to be against it.

It certainly seems worth asking.

That presumes that the "learning effect" of struggling with a problem
is more useful that being taught the answer.

Giving novice students brain teasers and expecting them to work it out
themselves is not always the best way to teach. Recent experiments
show that for new learning, it is much more valuable to present
questions with fully worked examples and solutions. Questions that
require application of knowledge should only be asked once the basic
knowledge has been acquired.

Whether the question originated from a school assignment or someone
trying to learn from some other source doesn't make much difference to
me. Such a basic question infers a very new student, the answer
should be framed within that context.

Indeed it does.

I wouldn't think that is a good way to go, not without asking the OP what
it's intentions are, and what work he/dhe has done sofar.

Recent experiments
show that for new learning, it is much more valuable to present
questions with fully worked examples and solutions. Questions that
require application of knowledge should only be asked once the basic
knowledge has been acquired.

I wouln't trust those "recent experiments", since they are
counterintuitive and I don't know what controlled environment is
presumed.

Whether the question originated from a school assignment or someone
trying to learn from some other source doesn't make much difference to
me. Such a basic question infers a very new student, the answer
should be framed within that context.

So, as I said, without confirmation of tat context, we should presume the
OP is helped best by not answering his/her school asignment for him/her.

I apologise, and take back my statement. It seemed to me as though you
were saying that what he was wanting to do was "pretty silly".

When you mentioned a class, I thought you were referring to a
JavaScript class (object), it never occured to me that you meant
educational class. Hopefully you can see where I was coming from,
taking your post in the context that I did. I've seen many posts which
set out (or at least appear to set out), to flame someone, and their
ideas.

My humble apologies again. Now if you'll excuse me, I have a rather
large foot to remove from my mouth.

I'll share the blame and will try to be more careful about using the
word "class" in the future.
