emptying a field

[barney]

I'm wondering if I can use JS to forcibly empty a form field (sorry if
this is an FAQ - I can't find much reference to it in the group via a
quick Google search, and the one solution I did locate doesn't seem to
work).

The relevant bits of the form and script are below. The alert when the
contents of the two fields don't match DOES work, as does the focus on
the field NewPassword, but I would like if possible to empty the fields
NewPassword and NewPasswordAgain when they don't match.

<SCRIPT language="JavaScript" type="text/javascript">
<!--
function checkData()
{
var f = document.forms["new_entry"]

if(!(f.NewPassword.value == f.NewPasswordAgain.value))
{
alert("The two entries of your password didn't match.");
f.NewPassword.value == ''";
f.NewPasswordAgain.value == "'';
f.NewPassword.focus();
return false;
}


return true;
}
//-->


<FORM name="new_entry" method="GET" action="submit_company.asp"
target="_self" onSubmit="return checkData();">
<P>Choose a password of five to ten characters.</P>
<INPUT type="text" size="10" maxlength="10" class="visibletextinput"
name="NewPassword">
<BR>
<P>Re-enter password:</P>
<INPUT type="text" size="10" maxlength="10" class="visibletextinput"
name="NewPasswordAgain">
<BR><BR>
<INPUT type="submit" class="submitsmall" value="continue">
</FORM>

Dohhhhhhhhhhhhhh! It works just fine - I was uploading the new version
of the file into the wrong FTP directory!!! Sorry about that.

Superfluous.

if(!(f.NewPassword.value == f.NewPasswordAgain.value))

f.NewPassword.value == ''";

Looks wrong, twice. Copy'n'paste code for safety, don't re-type/

<P>Choose a password of five to ten characters.</P>
<INPUT type="text" size="10" maxlength="10" class="visibletextinput"

xxxx
should be password : you have more " than are necessary.

That is an understatement: the line makes use of a proprietary extension
of ECMAScript in an HTML context. In a strict ECMAScript implementation,
it would be syntactically incorrect (`<', `!', and `--' being operators)
and therefore trigger a syntax error.

In an XHTML context that is parsed by an XML parser, it is likely to
comment out the entire script, so that the script engine will never see it.

Thanks, John. Not sure how the superfluous quotes happened - they're
not in my text file!

wrt the INPUT type, I thought about password, but figured that - since
the possible user error here is not typing the same password twice - it
would be more useful for them if the characters were visible.
