I've build a carousel that will let users flick/scroll trough dates using the slick library. I've got some minor issues with the library, and a major one.
You can see the carousel here:
http://radiant-meadow-8480.herokuapp.com/
user=test,
pw=test
I'll list the issues in the hopes that you can help me fix them, but if not, it might help you recommend me another library.
Events only fire when you release you're click(mouse up). I would like to slide my finger/mouse back and forth, and see the data on the screen change.
You can't sling your finger/mouse to one side and scroll through a bunch of slides. You'll only slide though a few slides.
The biggest issue is the fact that the slide your currently looking at will change, if you add slides in front of it. To get past this you have to destroy the slick object, and reinitialize it. This makes it way less smooth, and close to unusable on my old iPhone 3g.
I don't have any easily sharable code, but I hope the demo on the page, plus my issues listed can help you recommend a better suited library, or a fix to my current implementation.
I've also looked at iScroll, but the infinity scroll gave me nothing but problems, and the documentation seemed a bid lacking. It's also my understanding that the author is working on an updated version, and haven't updated the current release for over 6 months.
I would go one step out and question your usage of a carousel at all.
Why?
If you are doing mobile development, just allow mobile devices to use their built in ones, e.g. for iPhone use
<input type="date"/>
See Date Picker for iPhone Web Application.
Carousels for date selection on desktop are kludgy at best, including this one.
Carousels (although yours is slightly different) are generally considered bad UI. This is more of a slider than a carousel, granted. Reference:

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 can't seem to find the correct set of scrollView options to disable the overscroll/bounce effect. I'm using the last example on this page:
https://famo.us/integrations/angular/docs/unstable/api/directive/faScrollView/index.html
End goal is to have a sidebar menu like every single app ever made in the last 5 years. You would think it would be a more popular example for this framework, but I can't seem to find any useful ones for FA.
I have been told multiple times that setting edgeGrip : 1 in the options will make it no longer bounce. It doesn't work for me and no ones showed me a fiddle where it does work. I don't use the angular integrated version of famo.us so I'm not sure I can be of much help.
I personally used a generic sync and built a scrollview with that. Its similar to how the draggable works. Which is what i suggest, the draggable can give you a 'scroller' without a bounce. The down side is it won't be smart enough to not render things outside it's view. For my use I was building a form that was maybe twice the height of the screen and it works fine. If you want the non angular / straight famo.us version I use let me know. Hope the edgeGrip works for you.
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...

I've built a horizontal accordion with jquery. I'm having a problem with it. When it animates from one panel to another there's a jump at the right hand edge of the carousel. I've tried everything to get rid of this...adding widths...changing the js..removing whitespace from html etc..any suggestions?

Two relatively reasoned through musings on that issue.
I have run into this previously - I think it is a particularly nasty little issue that the community on the pluging has been trying to find a workaround for. The markup at the links above is probably a bit different but the application should be no different when adjusted to your case.
