View Full Version : Ultimate Fade-in slideshow (v1.5) in Safari 2

1) Script Title: Ultimate Fade-in slideshow (v1.5)

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex14/fadeinslideshow.htm

3) Describe problem: I'm on a Mac. The script works great in Firefox. The script page says it should also work in Safari 2 running on OS 10.4 (Tiger), but it doesn't for me; the slides just follow each other without fading.

Here's the URL of my page:
http://www.stamaty.engelbachdesign.com

Any help will be appreciated.

I tried to get DD to fix that. This is how it should be:
(code follows)


Thanks, John.

I don't see any difference between this code and the code I already have, but I'll try it tomorrow and see if it works.

The major difference is the addition of tests for and (if supported) use of style.opacity which is supported by Opera and Safari and FF (FF also supports -moz-opacity). The script as listed in the DD library only checked and used (if supported):


alpha(opacity)
-khtml-opacity
-moz-opacity


There were a couple of minor typos in the DD version that I fixed as well. These would only be problems in a few rare browsers like Konqueror (should it ever start supporting -khtml-opacity) and possibly some legacy browsers that support -moz-opacity.

Just noting that I'll second that the script fails in Safari 2, OSX 10.4

John,

Thanks so much. The changes did the trick. Not only does the code now work in Safari 2 on OS 10.4, but it also works in Safari 1.3.2 on OS 10.3.9.

Great work!

Cheers,

Tested with Mac OS X 10.4.9 and Safari 2.0.4 and fade works well.

Wow.. somehow I screwed myself. I did some updates to the Mac and rebooted.. and now fade is broken.

A related JavaScript error (which is apparently corrected in this version of the script) in recent versions of WebKit (http://webkit.org/) is being tracked here:

This version also works properly on Safari 3 Beta on the Mac. Thanks guys! :)

Just a note, it works well now (and didn't before I replaced the script with the one in the forum) on the beta Safari for Windoze.
