Hello Gurus:
I have a validation script (below) that is somehow messed up. If the
Name field is blank, I get the alert message, then the browser window
goes to a blank document with the word "false" on it. What the ?!?!?!
To test, I commented out the 'return false;' code in the second IF
block, so now if there is a value in Name then I get the alert message
for Email and the page stays put.
What the heck is going on here, and am I doing wrong? BTW, the
"submit" button is a graphic.

Hello
1. Better make use of ONSUBMIT event
2. If you are just to fix what you wrote, simply add: void(0) after your
validate function call, just like in:
<script>
function fnc1()
{
if (/*validation ok*/)
{
// submit the form
FORM_VAR.submit ();
return true;
}
return false;
}
</script>
</head>
<body>
<a href="javascrip t: fnc1();void(0); ">adsasd</a>
</body>
</html>

Thank you all for your help. I removed the <a> tags surrounding the
<img> buttons in the form, and put the "href" code into an "onclick"
event within the <img> tag (thank you Evertjan!) Also removed the "x"
variable lines since they were redundant.
I have a question about Evertjan's response: <script language="JavaS cript" type="text/javascript"> do not use language="JavaS cript" <!-- do not use <!--
Why should I not use language="JavaS cript" or <!-- ??
Many thanks again!
Kurt
PS: I am using XHTML which requires self-closing empty tags (<br />).
I tested the page in various browsers (IE6, FF1.5, N6, N8, Opera8.51),
and only Netscape 6 showed a discrepancy by adding additional space
underneath various images (assumed).

language="JavaS cript" isn't a valid script attribute in HTML 4 or XHTML,
try a validator on your page.

Indeed.
While it entirely possible to insert:
// this line serves no intended purpose
every other line in a js, it would only cloud the appearance of the js,
and do not good whatsoever. The same goes for the above two.

According to validator.w3.or g, the web page (and the entire site)
passes validation for Doctype XHTML 1.0 Transitional.
I was about to argue, since it's found just about EVERYWHERE, that the
language attribute is needed, but thanks to you I found out that it is
indeed deprecated. I will stop using it in the future. However, W3C
still says to comment out code for non-script-aware browsers (see http://www.w3.org/TR/html401/interac...dx-user_agent).
Many thanks for the lessons learned.

I have what should be a trivial problem. I am using XMLSerializer to
serialize an object. It serializes boolean values as "True" and
"False". I then want to use an XSLT on this XML, and I want to use
one of these booleans in a test. How do I convert one of these to a
boolean in a test?!? I know that I could compare it as a string to
"True" or "False", but that seems extremely crude to me. The

to halt the computation immediately and return false.
