Validation: iframe , onmouseover and doctype

J. B. Moreno

I've got a page with an iframe in it, and a javascript that handles an
onmouseover/onmouseout for it. Everything WORKS, but it doesn't
validate...

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd"> <html>
<head>
<title>test</title>
</head>
<body>

<iframe id='ifID' name='ifName' src='if.html' onmouseover='over()'
onmouseout='out()'>no content </iframe>

</body>
</html>

What doctype should I be using? Or do I just say forget about it?

If you want to use the onmouseover/out attributes on the iframe element
in the markup then I think you need to write your own DTD extending the
HTML 4 DTD as needed to be able to validate the document without errors.

Depending on your needs you could of course decide to make the document
valid against the W3C HTML 4 DTD as far as possible but accept getting
errors on those two attributes.

Or you could remove the attributes from the markup and use script to set
event listeners as needed with script alone.

OK, thanks.

Probably best to just let those two errors go -- I'm not fanatical about
validation, and this seems to be a reasonable case of ignoring it.

The scripting on this page is supposed to be handled by someone else.
