Browser 'form' differences?

[evan.tually]

I'm new to trying to use javascript, so I'm probably doing something
wrong.
This code works with MSIE, but not with Firefox. And advice greatly
appreciated.

In HTML page "head" section, I have this line:
<script language="javascript" type="text/javascript"
src="lib/form.js"></script>

In the "body", this is the FORM:
<form>
<input type="button" value="Log in to Upload" onClick="login()"> <br>
<input type="button" value="Forgot Password" onClick="sendpw()">
<input type=text name="pwd" size="48"> Enter registered email address
and click "Forgot Password"
</form>

The file "form.js" contains:
function login() {
vMsg="lib/login.php";
window.location=vMsg;
}
function sendpw() {
pw=document.getElementById('pwd').value;
if (pw == '') {
alert("Enter a valid email address");
}
else {
vMsg="lib/check.php?USERPW="+pw;
window.location=vMsg;
}
}

Thanks in advance,
Evan

<input id="pwd" name="pwd" type=text size="48">

with an ID, because

function sendpw() {

here you want to get an object (or element) by its ID
get element by ID

pw=document.getElementById('pwd').value;

With IE it works with name because IE uses to aproximate whatever he touchs

The _only_ part of this that should be implemented with javascript is
the validation of the non-empty password (which should be done with an -
onsubmit - handler on the form element). The rest should be done with a
normal HTML form (real submit buttons) and PHP (in your case) on the
server. Part of learning javascript is learning when not to use it.

<input type=text name="pwd" size="48"> Enter ...

function sendpw() {
pw=document.getElementById('pwd').value;

<snip> ^^^^^^^^^^^^^^

Your HTML contains no elements with the ID attribute "pwd". IE is in
error in returning elements with the NAME attribute, but no other
browsers repeat that fault. See:-
