Check for support for hover on non <a> elements

[Robert Mark Bram]

Hi All!

Problem I began with: Netscape/Opera supports hover for different elements,
IE only supports hover for <a> and I want to use hover for <td class="menu">

I then found a fix using some Javascript here:
http://webpages.charter.net/mmmbeer/...bitrary-hover/

It works ok for IE now.

Problem I now have: I don't want the script to run in a browser that does
support hover for <td>.

In other words I noticed that the script was still running for Netscape and
Opera - but I would prefer to let those browser's native hover support to
work since I notice that in some cases the script can introduce lag at
loading time.

I don't want to sniff for IE: I know how unreliable browser sniffing is. I
would rather sniff for the lack of hover support.

Can anyone give me clues as to how this might be done?

Any help would be most appreciated!

Rob

You could use conditional comments. It's kind of browser sniffing, but
it is reliable.

Hi Mark,

Thanks for the reply!

Well, this seems to work ok:

<!--[if IE 5]>
<script language="javascript" type="text/javascript"
src="../bin/ieHoverFix.js"></script>
<![endif]-->

It feels like a hack.. *grin* but then again, just about every single
'advanced' thing I try to do in Javascript lately ends up feeling like a
hack! *sigh*

Yep, that's the one. Note that the above will only affect IE5.x, not
IE6. Change the first line to <!--[if gte IE 5]> and it will work in
anything from IE5 up.

It is. ;-)

No, that is then a normal HTML comment, so other browsers will still see
the stuff in between. If you wanted other browsers to see it and *not*
IE, you could do <!--[if !gte IE 5]-->

Fun for the whole family. :-)

Ah, so *that's* how the buggers work. Who'd have guessed :-)

Indeed.

Would it be better to use <!--[if IE]> to detect all versions of IE?

That's the whole point. He wants some hover behaviour to be
included only for IE. To other browsers the above code looks like
a comment. Only IE evaluates it, only IE will load the extenal JS
file. If IE7 (or 6.5 or 6.0SP2 or whatever) starts supporting
td:hover, he can change the condition to be something like:

<!--[if lt IE 7]>

That's not a problem, though, because IE Mac's rendering engine is
different from that of IE Dows.

Do you plan to maintain the page in all future?

Otherwise, I would recommend:
<!--[if lt IE 7]>
so that you don't block future versions unnecessarily.

Does IE Mac support :hover on elements other than <a>?

Nope. IIRC it's only KHTML, Gecko and Opera 6+ (perhaps 5.1x?) that do.

How does Mac IE get on with VBScirpt? If it can understand it then maybe
a VBScirpt implementation would be successfully ignored by all non-IE
browsers. Or VBScript being used to write the script tags into the page
(so it wouldn't happen on non-IE browsers).

Or maybe specifying the language type as "text/jscript" would be enough
to keep non-IE browsers from attempting to load/use the external JS
file.
