I would like triggering an animation when the user is coming to the div which contains the animation. I tried with waypoint and it worked but now I want to try a pure angular solution.
Different options I've found are the following :
angular-waypoint
triggering the event on mouseenter/mouseleave
constantly looking for the position and the scrollbar.
I am not asking for a solution already made, but rather advices!
Thank you.

Here's some more details - due to some weird restrictions with the YouTube API, I am forced to push a container off the page to give the impression of hiding the container.
I achieve this by using this class:
.my_hide{
margin-left:-9999px;
position:fixed !important;
}
And by using the JQuery methods $("player-list_container").removeClass("my_hide") and $("player-list_container").addClass("my_hide") to control the toggling.
However, the toggling looks jaunty, and the container jumps up once the class is removed. I want to be able to transition smoothly from one state to the other, and am at a loss for how to do it.
This behaviour can be demonstrated here
Add a video by typing in and searching for anything, and then hit the Play button located below. You should observe the behaviour described.
Iam assuming you 'are not able to'/'not want to' manually hide the container but want to change its position so that it is outside the boundaries of the page and it looks hidden.
In that case changing the position property will definitely give you a jumpy instead of a smooth effect since this affects the whole layout of the page (Read more). What you can instead do is change its position using CSS3 animation's translate property.
Here's a demo I've coded which does exactly what you want.

The "Click me" button toggles between taking the container off and on the page and it does it smoothly. You can also adjust the time which it takes to change the position of container. (As of now its 500ms)
I want it to look like the container is fading in in position meaning I would have to get the container to that position before using any type of animation function.
Then, don't throw the element way off the page with CSS. Leave it where it is, and hide it with .hide(). Then fade it in with .fadeIn().
You'll need to manually size the container, as it won't expand to contain a hidden element.
On my screen it just popped up. Im not 100% sure what type of pop in effect you want but that said, check out http://api.jquery.com/animate/
i was going to code up an example but that page has a bunch!
good luck!
PS: scroll down for all the visual animation examples.
Here is some sample code:
$('#myBtn').click(function(){
$( '.ytv' ).fadeTo( "fast", Math.random() );
//add animation code here;
});
check out a rough fiddle.
edit: heres a rough example: http://jsfiddle.net/somdow/Lef9n/2/
just click the red area to the right of the video
Animate function in jQuery wll help you
I'm looking to make a mock-up html app. I have been using reveal JS and my own jquery to make the bulk of it, but i need only part of the page to be "sensitive" to the swipe gestures. Does anyone know of a way to make only part of the screen area sensitive?
Thanks
Well put an HTML element there covering the desired area and bind the swipe event to it.
For more of a concept you should try something and comeback with a code example if no success.
I'm trying to find a Javascript snippet that I can archive the UIScrollView + UIPageControl effect of the iOS using Javascript and CSS3.
Generating the page control to a dot to each view and do the switching is very easy, but the complicated part it is to do the elastic movement.
I would want to do this myself, but it seems to much work to me, like hours of work, tried googling, but I not found anything. I don't like JQuery but the mobile framework doesn't seems to do this.
If I had to do this by myself, do you guys have any suggested approach? I'm thinking in using a parent div, with a bunch of divs inside for each view. Use the parent with overflow: hidden;
and attach event to the parent view and listen to drags and bind to the horizontal scroll offset. This would be a good way? or using css transitions with left or translate-x would be more smooth?
EDIT:
This is what I tried (not working very well): JSFIDDLE
Yeah,
Im not sure about touch swipes, although i think the 'activate' or 'touchstart' handler might be useful. Using CSS3 transitions to achieve the elastic movement is quite smooth, just alter the left or right style property of your internal div and the transfom will move from its current position to where you need it to be.
This is not the worlds bestt example but have a look here

Im busy with an mobile website design, but im not that good with javascript. So i would like to have an startup script which i can modify. So i dont know where to start.
What i want to achieve is the following:
When you click on an button/div (onclick function) an div slides up (change margin top/make an invisble div that slides in height). And on the same click an other div slides open. (So the second div isnt shown at first but on click it is shown.
I dont know if this is possible but im sure you guys know if it is.
Kind regards,
Augus
yeah it can be done easily with Jquery. you can even set sliding speed.
you can check this thread and you can do something similar. I have answered in that thread as well.
or you can do it using below function:
jQuery('#div_id_1').slideDown("slow");
jQuery('#div_id_2').slideUp("slow");
Need to display an element (div) ontop of webpage. During scroll the element should disappear and reappear after scroll ends.
To add to the complexity:
our code is a guest code (thus we cannot manipulate DOM structure etc).
our code is intended to work on iPhone/iPad (mobile Safari browser)
We've tried to listen to touchstart event on document / body and hide the element (div) in our dedicated handler. However, in some sites, (when DOM structure becomes reasonably complex) the scroll response time increases significantly, even if handler implementation is entirely empty.
We are looking for the proper way to manage the element (re)appearance with a minimal affect of the user experience while scrolling.
I would think Javascript is your best solution. You can dynamically insert your DIV to any content using document.createElement, then also add some javascript to listen for onScroll...
You could even populate the DIV using custom HTML built from the native code if you want.
Any help?
I don't know if you are a jQuery user, but this .scroll() function may help you do exactly what you want to do. Check out the demo to see how it works.

In recent iOS version (5.x) fixed positioning (position:fixed in CSS) is fluently supported, so that your element will be positioned on screen coordinates. That might be a good starting point for solving your troubles.
