Re: [jQuery] jquery customised easing

This can be achieved by using the easing plugin

http://plugins.jquery.com/project/Easing

which is included in the jQuery UI Effects Core. See here for a demo:

http://jquery-ui.googlecode.com/svn/trunk/demos/effect/easing.html

I think the one you're looking for is 'easeOutBack'

Hey all. I'll be quite amazed if anyone can help me with this one. I've been
scouring the internet trying to find a tutorial on this, but no such luck!!

I'm putting together my own little side navigation and I have an affect in
my mind that I want to achieve and I'm sort of half-way there.

I've thrown together [URL=http://www.webhero.co.uk/help/]a demo, here[/URL]
( http://www.webhero.co.uk/help ) of what I've made so far.

I basically want the background to slide up and down depending on what menu
the mouse hovers on to, with an easing (or bouncing) effect when you move
over each one. I want the bouncing thing to go both ways, so that if the
background is at the bottom and you hover over a link above, the background
moves a little past the final result and then back -- so wherever it moves,
it bounces or eases a little into place.

Another thing to consider is that whatever page the user is on, the little
bar will start off and go back to there - so in the demo we're presuming the
user is on the 'web design' page.

(You'll need to see the demo by now to see what I mean :P)

As you can see, I've programmed this to work fine if you're moving your
mouse top to bottom, but if you go from bottom to top - you'll see in the
code that I'll need to put some conditional statements around the animations
to test whereabouts the background currently is - and that's what I need
help with really. Also if anyone has a few tips on how I can shorten down my
javascript code here that would be awesome :)

Or, if anyone has a better way of achieving what I'm trying to altogether
then I gratefully welcome anyone's thoughts.

It'll be easier to view the source but I'll include the html and JS here.
