John,

About the client-side validations :

1.Give an ID to your input.
2.You can add a mecanism to trim spaces of the value entered by your
user
function stringTrim (s) {
return this.replace(/^\s+/, '').replace(/\s+$/, '');
}
String.prototype.trim = stringTrim;

2. Now you can use that prototype to check your strings :
if(document.getElementById('txtAddress').value.tri m()=="") {
alert('You must specify your address');
document.getElementById('txtAddress').focus();
return false;
}

About the cookies stuff :

Do you use any server-side technology like ASP / PHP or are you using
plain HTML combined with javascript? if it is the former than you don't
need cookies in order
to check if a user is already registered. Just make the checkup
server-side in your database / xml file. It will be more robust...
remember that people can remove
their cookies anyway.

But if you don't have any server-side technology, I think you can
access cookies this way in Javascript. I saw this on newsgroups and
never tested it so
forgive me if it is wrong =) :

To write :
var exp=new Date(2010,1,1); // cookie's expiration date
document.cookie = "CookieName=CookieValue; expires=exp.toGMTString()";

To read :
just parse what is into document.cookie the way you want.

Good luck
François

Thank you for you Help..
As far what you were talking about on the server side there is no
server. I understand what you say about the cookies but this is just
for a school project to get a grade it not going on an actual web site.
Any more help would be appreciated.. Also how do I take them to another
page to display that their information is already there??

Thank you..

Hello John,

To redirect the user to another page you can use
1) window.location='mynewpage.html';
or
2) window.navigate('mynewpage.html');

If you want a good javascript reference, you can go to that site :
http://www.devguru.com/. It may as well contains cookies
reading/writing examples.

Good luck
François

You said "good javascript reference", that is not a good one. It is not
even close. So, after you go there, go somewhere else looking for a
better one. Try the group FAQ.....

If its cookie code is as poor as the examples I looked at, stay away

I didn't know that this function was depreciated, my bad.

Why are you saying this? Last time I checked it was fine. There may
exists better references but devguru isn't all that bad. The group FAQ
may be a better starting point though, I didn't think about it.

Hmmm. Because it's true?

Quote:

Last time I checked it was fine.

When did you check it and what is your criteria for "fine"?

Let me give you a few examples of the "fine" quality it has, fair enough?

setAttribute is known to be buggy in IE. Yet, devguru has not one
mention in the entry for setAttribute that says it is buggy in IE. What
good is a reference if it gives the false impression that something is
reliable when it isn't?

Nest. eval.

This is what devguru says about eval:

<quote>
The top-level function, eval, evaluates and/or executes a string of
JavaScript code that is contained in the codestring argument.
</quote>

First, it doesn't "evaluate and/or executes", it executes what you give
it. Plain and simple.

But, that is *all* that it says about eval. And there is no way on the
planet you can even come close to explaining eval in that one sentence.
And even then, that one sentence is patently wrong.

Shall I continue?

The site might be a basic minimum site to get a little information from,
but it is nowhere near a "good reference".

Quote:

There are many better references and yes, devguru, is that bad.

Quote:

The FAQ for this group is a better starting point than 99.99% of the JS
sites on the web.

There's no clear distinction between the terms in English as applied to
Javascript.

If the string supplied contains an expression, with no assignment, then
"evaluates" is a perfectly good description.

If the purpose of the eval(...) is to return a quantity, i.e. the usage
is as X = eval(S) , then "evaluates" is a perfectly good
description, even if S contains assignments.

The description "evaluates" is only inappropriate if the return value of
the eval(S) is (whether or not defined) irrelevant, the code being
executed for its side effects.

Consider an input control which is given a string S such as '3+5' from
which Number 8 is required. At the ECMA-spec level, "executes" might be
appropriate; but in normal English discourse, "evaluates" would be used.
- and ISTM that a corresponding statement might well apply in "deneb"'s
native language.

redirect, so if the user has for example already enterd their name and
it is stored
in a cookie it goes to another page called Error.htm and give them a
message saying they already filled out the form.
Please I have looked this up on diffrent pages on the internet and

cookie redirect part and help me out.

Thank you.. I appreciate your help in advance..
I have worked on this all weekend cutting and pasting from the
internet and modifiying but I can't get it to work right.. It is not
like I am just asking for answers I have
given it 100% effort but honestly I am not good at programing and this
might be a simple task for you programers out there but it is a
nightmare for me.

Thank you
