I'm developing a website for someone who requested a dynamic sliding page when you scroll (i.e. like this). At first I was thinking it was something I could use CSS transitions for, but then I realized there might be a JS tool out there which could make it work.
I discovered this page of dynamic movement examples with an associated library on github, but I'm not quite sure how to make it work. Basically, I'd like the page to listen for the event of a scroll, and then slide up a section of the page in the same way as the example above. When looking through the code for the dynamic movement examples, it seems like it's a a bunch of cases in the JS file that get used somehow in the event of a button press.
Please, if anyone is familiar with building something like this, please let me know how it might be done.
I would encourage you to make use of fullPage.js.
It is nowadays the most popular library for single scrolling pages. It has plenty of options, methods and callbacks and you can almost do whatever you think of with it.
Compatible with old browsers, kinetic scrolling (Apple laptops) and touch devices.

I'm trying to create a page similar to new google calendar landing page http://www.google.com/landing/calendar/
I'm using skrollr(https://github.com/Prinzhorn/skrollr) but I can't get the effect right, on google landing page if you do a small scroll it will send you to the next block and with skrollr I'm not able to get that navigation. Any ideas how I could reproduce that? is it possible to do with skrollr or you would recommend another js plugin?
Thanks!
In case you still haven't found a solution yourself, I've been tasked with doing a very similar thing. There are two ways of achieving this that I researched and choosing the right one mostly depends on the complexity of your design/expected result. Unfortunately I can't provide a link because the site won't be live for next couple of weeks.
This is what worked for me:
I used fullpage.js library to achieve 'full-page' scroll effect. You could also take a look at onepage-scroll.js and see which one fits you most - they don't differ that much in terms of functionality though.
Benefits of using fullpage.js (among other things):
integration is quick and simple
allows a lot of customisation through options hash
provides callbacks when scroll to another section is triggered (before or after it happens)
enables you to manually trigger a scroll via 'methods'
works surprisingly good on iPad/iPhones. Probably on other mobile devices as well, although I can't fully confirm that since that
wasn't a requirement for my project.
Now when you've got section-to-section scrolling in place, what's missing is the animations. Considering that fullpage.js provides you with callbacks, it's as easy as adding a class when a transition to another section/slide happens and then using that class to trigger an animation of your choice through CSS. This is what worked for me without facing major problems.
For more advanced things:
If you're looking to build something more complex, then I strongly recommend that you take a look at tween.js. This is what google used on the landing page that you've provided in your question.
It's a very powerful tool hence it requires quite some setup + it moves animations to javascript, which might be a hassle. I would rather keep them in CSS where they belong and dont use javascript until I really need to.
FYI I also started with skrollr but it won't really work with 'fullpage scroll' because what it really does is disabling scrolling and animating body/html through translate. Skrollr bases it's behaviour on scroll event which will not fire if you use libraries I proposed.
EDIT:
It appears that you can actually use skrollr in par with fullpage.js. You can see the answer on how in it's FAQ site. Thanks to Alvaro for claryfing that! Even then, I wouldn't use skrollr unless you really need it for some advanced parallax scrolling effect - as said before, depends on your needs though. :)
Let me know if you have any doubts or something is not clear in my answer.
Good luck!
I have some separately made HTML pages that id like to slide horizontally between.
Ive looked everywhere but I havent found exactly what Im looking for. Can anyone help?
I'm not sure if there is a plugin written for a fully general solution for completely different pages. It would need some kind of an AJAX load, and a nice transition with possible history manipulation.
I don't know how well it suits your needs, but the old Google HTML5 slide template had this functionality.
There are limitations on what you can do with it, but they provide convenient keyboard and mouse navigation.
I've built my mobile site using the jQuery Mobile UI but I now realize that I need some functionality to be different between it and my desktop site (datepicker dates should be longer on the desktop site, etc).
I've looked into Modernizr and matchMedia to help me load separate js files but I can't figure out a nice way for it to work responsively. Modernizr only works (unless I missed something in the doc) on the initial load and I'm having problems with matchMedia executing multiple times as it crosses the min/max-width threshold. It works sometimes but the trouble is in adding/removing the separate js files. On top of that (but not a huge issue - I don't think), Chrome fires off an error when loading scripts into the DOM from another script.
Would the best thing be to write one js file and then add a listener such as $.mobile.media("screen and (min-width: XXXpx)") to the body's width, changing my needed values?
I may be making this too hard for myself, or missing something obvious because I'm trying to keep HTTP requests and site size as small as possible, but I can't figure out a good solution for this.
Thank you!
Lightning Round Bonus Question: Is it good practice/proper to keep all of the jQuery Mobile styling (data-role data-id data-theme) after switching to the desktop site? It looks awfully .. awful for someone only viewing it on a larger screen.
IMHO, the best approach would be to introduce a couple of flags in your javascript, like "isMobile", "isTablet" or "isDesktop", that would be set within a method attached to the "pageinit" event of your webapp. Later on, you could check that flags to act accordingly with the proper version in the specific parts of your code.
The way you can check that flags depends on your architecture. In the project I am working right now, I extract that information from a class attached by the back-end on the body of the page, but that's because we have that info. You could try to use a library like Harvey to observe the media-queries that would be trigger, and set the flags accordingly. I don't think that your options ends here, but I am afraid I can't help you more!
Let me start by saying I have read plenty of questions and blog posts relating to the use of combinations of backbone/jQuery mobile and comparisons of backbone/Sencha, and have actually had my head in this space for some time but still haven't found quite what I'm looking for.
I'm very familiar with Sencha and have used it for wrapped (phonegap etc.) apps in the past, and I really like it. However for a smaller code base for web projects and more control over browser compatibility and various other reasons it's not quite appropriate for certain tasks.
When I start trying to engineer mobile (but also desktop and tablet) backbone webapps from scratch I find I miss three key things
General mobile 'init', filling the screen etc. (although this is the easiest to replicate)
Tabbed, iOS-style, navigation (of course I can roll my own, but it seems silly)
Scrolling - both scrolling a piece of content, but especially the carousel and how the carousel is linked to the tabbed interface
I'm not massively bothered about mimicking each device's native OS style throughout the app, and in fact would prefer to (whilst following some sensible conventions) make them look a bit different.
Ember has flame and I've used that before, that's kind of the thing I'm looking for.
I know I can build up a toolkit of jQuery mobile, custom script, jQ plugins/iSroll, CSS libraries, backbone UI etc. and do like the idea of compiling my own 'stack' but for some reason it just doesn't feel right.
So, to bring this back around to more of an actual question. I guess I'm looking for ideally a single project that isn't specifically linked to a library - and in theory could run on it's own on a statically coded page if needs be (even though that wouldn't be the case for me now). Or perhaps some words from others who have been on a similar journey and perhaps ended up on the mix of libraries I mentioned earlier with why they decided this was the best solution.
I'm not looking to do anything too crazy, say something a bit like the old sencha oreilly example but using some carousels, and I'd cover the multiple devices and browsers with a mix of Responsive CSS and a bit of JS.
I'm going to continue looking at this myself too and report back if I find anything interesting
Cheers
EDIT
While looking into this, I realised its only really the carousel and scrolling that I really wanted from Sencha. I noticed that Cubiq has a nice slideview component that handles the carousel very neatly and with a small footprint. I found a stackoverflow answer about using this with the original iscroll for vertical scrolling. See my answer below for successfully using the two together
How to use iScroll4 with SwipeView?
This would need some tweaking to work appropriately on desktop. and I'd like to control it from a tabbed UI too. Anyway, I'm not near answering my own question but given this has had a couple of upvotes I'd post some of my thinking.
Quick edit
You can attach events for tabs to the slideview https://dl.dropbox.com/u/81328343/scroll/1.html but at the moment, it only animates for next/prev and not direct page (tab) access

Very big library of components.
I've used Twitter Boostrap with Backbone...
http://twitter.github.com/bootstrap/
ive seen the plugins etc to create a carousel of images etc, but what i want to achieve is having a content slider.
The content would be approx 500x400px, i was hoping to just give the content a div with unique id, and have it show for, say 6 seconds but if your mouse enters then for animation to hold.
I was thinkin along the lines of using:
$(#id).fadeOut(*time*);
Im on my mobile so its not the best example of code. Id be using set Interval for timeouts, however, do you think i should opt for a plugin? I already use many on my site, so would prefer just this page to use some simple jQuery.
This can be done in jQuery without too much work. You already know about setInterval() and the jQuery animation functions. All you'll need to do is implement mouseenter() and mouseleave() to properly pause and continue the animations. Perhaps a setInterval() every time mouseleave() and a clearInterval() every time mouseenter().
I agree with marcosfromero that plug-ins are great so you don't have to develop the whole thing again, but you stated that you have a lot of plug-ins already, so it could be better to write it yourself so that you gain more experience and have more control over it. I would say the choice to go with a plug-in depends on whether you find one that fits your needs and the size of it (even with minify, size does matter and one must consider blocking while JS files load).
If a plugin works for you, I don't see the point in developing the whole thing again.
Recall that most plugins offer a minified version so size wouldn't be a matter.
You can also use some automatic tool to minify code and join several JavaScript source files to prevent lots of requests.
If you still think the plugin is too big for your needs, consider inspiring yourself with the plugin's source code.
