Hey Brandon, thanks for adding that option - it is perfect. I notice
you have set the default as opacity:true (as in, you decided against
taking out setting the opacity by default). Is that because of your
tests (mentioned in your later post) where the iframe showed through?
Regarding that, you said "if the element has a background color on
it, the iframe will show above it". When I tested this on my demo
page I found that with the opacity code deleted the iframe *always*
showed above the element it was attached to *regardless* of whether
or not a background colour was set. The reason I didn't notice this
earlier is because the element's children (li elements in my case)
have background colours so they hide the iframe in effect.
So I think your current default setting of opacity:true is probably a
good idea because 1. it emulates its regular behaviour, and 2. when
the situation is like my case the developer can take advantage of
setting the opacity option to false and enjoy perfect animations.
This is perfect for my menu plugin and I have updated my demo page to
take advantage of it. This involved using your option to set
opacity:false and also adding the following line to my superfish
plugin's 'out' function:
.find("iframe", this).remove();
I had to add that to the plugin because I wanted it to happen after
the mouseout delay, not immediately on mouseout. Anyway, now both
slides and fades work perfectly in IE6 (check my demo page) and there
is no lag whatsoever! The menu now works equally well in all regards
for IE6 as it does for other browsers. I guess the only downside in
my case is how convoluted the code is for applying the bgIframe to
the menu:
$(document).ready(function(){
$(".nav")
.superfish({
animation : { opacity:"show",height:"show"}
})
.find(">li[ul]")
.mouseover(function(){
$("ul", this).bgIframe({opacity:false});
})
.find("a")
.focus(function(){
$("ul",
$(".nav>li[ul]")).bgIframe({opacity:false});
});
});
Thanks for your help Brandon.
Cheers
Joel.
