anyone interested in an Effect.Slideshow?

I had to make a sort of slideshow for a site I''m working on, and I was
thinking of making it into a Scriptaculous object.  Anyone think of
reasons why I shouldn''t?  You''d have to pass in all the image
urls and a
div id, with an optional delay parameter to determine how long to leave
each image up before moving on.  I could also have a
''randomize'' option,
when set to true it would pull the images randomly.  It would cross-fade
them using Effect.Fade and Effect.Appear.

Syntax would be something like:
new Effect.Slideshow(''div_id'',
[''image1.jpg'', ''image2.jpg''...], { delay:
#.# (in seconds, with a default of 10 seconds), randomize: true/false
});

The script would create the img tag inside of the div (it''d actually
create 2, 1 hidden and 1 showing, then fade one out while the other
fades in).

What do y''all think of that idea?

If someone''s already working on something like that, then cool.

RE: anyone interested in an Effect.Slideshow?

How about this:
	<div id="slideshow">
		<div id="a"><img .... /><div>Some
description</div></div>
		<div id="b"><img .... /></div>
		<div id="c"><img .... /></div>
	</div>

Then:
	Effect.Slideshow("slideshow", { delay.... });

This would take all the children of ''slideshow'', and hide them
all except
the first, and then switching between them as before.

I like this better because I can now style each image as I want, and I can
also add text, or something else.  It allows more freedom, and all the
slideshow code does is hide/show the inner pieces without needing to know
anything about them.

In this case, I don''t even need images, I can do this with paragraphs
of
text, or whatever else I can find to put in my child DIVs.

Re: anyone interested in an Effect.Slideshow?

I think that sounds great. It seems like it would also be nice to have the
option of having the next image url determined by an ajax call.

Re: anyone interested in an Effect.Slideshow?

Heya,

Great idea!

Now if you can manage to have other effects than only fade/appear  
in... :)
Would be great with slides/blinds/what-have-you.

Cheers,
Thomas

That''s a great idea and shouldn''t be too tough to implement. 
Of course,
if you have a lot of images, loading them all with the page might make
the page load slowly.

RE: anyone interested in an Effect.Slideshow?

What would be really cool is if you could pass it a xml formatted
document that would have all the images in it and the load them on the
fly instead of loading them all at once.

RE: anyone interested in an Effect.Slideshow?

My idea, coupled with the ''Ajax to get the next image'' from
Casey would
alleviate the image loading problem.  The next image would just be
another element inserted as a child in my scheme.

Re: anyone interested in an Effect.Slideshow?

Tom, I think using the ahah mentality would work nice for what you are
suggesting. Pull in a fully formatted div, image, page or what ever you
wanted it to be.

So, the ajax call would return the entire child element to be added, not
necessarily just an image?   That could work.

AHAH is an other word for what Prototype and Rails does since like  
March 2005 (with Ajax.Updater).

I would think that''s who it would have to work (i.e. insert the IMG
tag)
if you wanted it to support anything, like DIVs full of text, or DIVs
with images and descriptions, like someone suggested.  I like the idea
of just sticking in any element better than only retrieving images.

Re: anyone interested in an Effect.Slideshow?

I like the idea.  Is it possible to have an optional callback that we
can register before and after the next "call"?  The callback could
take say the response object and the current slideshow object as
parameters.

so it''d be something like:
Effect.Slideshow(div, url, {delay:0.30, before:XXX, after:YYY});

XXX(slideshow) would get invoked after the delay.
YYY(slideshow, response) gets invoked after results come back, but
before they are displayed.

We could probably also use a stop() method to halt the slideshow.

RE: anyone interested in an Effect.Slideshow?

Ok, I have a rough draft working with the childNodes option, but I
haven''t implemented the ajax version yet.  As for the transition
effects, what pairs of effects should we use?  I have Appear/Fade going
right now, but I can easily add other options.  I was thinking of doing
the BlindDown and SlideDown options, but having the image that is going
away do the reverse won''t look right.  You''d have a new one
sliding down
while the old one slides up?  No, the old one should slide down, but
just start from the top and gradually slide away.  Is there an option
for doing that (i.e. slide down towards the bottom instead of sliding

RE: anyone interested in an Effect.Slideshow?

Could you set these as options with Appear and Fade as the defaults
	{ 
		showeffect: function() { Effect.Appear.... }, 
		hideeffect: function() { Effect.Fade.... } 
	}

That way I can make it looks as screwy as I want!

Check out the Draggable.prototype definition for how to do this.

Ok, I have a rough draft working with the childNodes option, but I
haven''t implemented the ajax version yet.  As for the transition
effects, what pairs of effects should we use?  I have Appear/Fade going
right now, but I can easily add other options.  I was thinking of doing
the BlindDown and SlideDown options, but having the image that is going
away do the reverse won''t look right.  You''d have a new one
sliding down
while the old one slides up?  No, the old one should slide down, but
just start from the top and gradually slide away.  Is there an option
for doing that (i.e. slide down towards the bottom instead of sliding
down from the top)?  The wiki''s in and out, so I''m not able to

Sure, I can add that, but I like the idea of having predefined pairings
available as well.  So, if you pass in your own, it won''t use a
pre-defined.

The functions will need to accept an element argument, like this:
 	{
 		showeffect: function(element) { Effect.Appear(element)
},
 		hideeffect: function(element) { Effect.Fade(element) }
	}

I''d also like to make it so you can pass in effect options when using a
pre-defined pairing.  So, maybe have this also:

{ 
	showoptions: { duration: 0.2 },
	hideoptions: { duration: 0.4 }
}

What do y''all think?

Re: anyone interested in an Effect.Slideshow?

I like it.  I''d also like to see (optional) before and after callbacks
on the AJAX request to grab the next content.

Actually, some thought needs to be given on how it''s going to
construct the AJAX request for more content.

If we rely on a session, we could just use the same defined URL for
each call.  It''d be much more flexible if we could (re)define the URL
between invocations.

So first call could be /my/photo?id=1
next is /my/photo?id=2 and so forth
and at /my/photo?id=10 we tell the slide show to stop.

But what if we can''t rely on consecutive integers, or if the ids
aren''t even numeric?

Any thoughts on how we can best control the sequence?

Re: anyone interested in an Effect.Slideshow?

As long as there''s a "before loading the next image, call this
function"
built into it, it shouldn''t be hard to make that function able to
redefine
the URL to be called to get the next image.

Re: anyone interested in an Effect.Slideshow?

Hey Greg,

awesome idea, I really look forward to see the "finished" version (or 
the first draft).

Here are my two cents: What I really don''t like with most of the 
slideshows online is that it does not preload the next images. So, 
everytime I click on "next" image, it takes a while. I would like to
see
a feature that "buffers" the next 3 (or "X") and the last 3
screens so
they are instantly there...

what do you think?

greetings,
benni.

Well, the way it''s programmed now it keeps a queue of
''unfinishedFrames''
and pulls from that to get the next frame.  So, theoretically, when I
finished the ajax-ified version you could just return multiple frames in
an ajax call and those would all be added to the queue.  I suppose I
could also add an option to let you decide at which point to ask the
server for more frames, like if there are X number of unfinished frames,
it''s time to call the server (defaults to 0).

I''ve got some more urgent things to finish up at work, but I should be
able to spare a little time over the next few days to wrap this up.
Btw, anyone have any idea why SlideDown and SlideUp aren''t working for
me here?  They throw an error deeper down in the prototype code and I
haven''t backtracked it yet.  Were there some bugs fixed in 1.5.1?  I
think I''m still on 1.5.0.
