Finding where element meets top of scrollable div

I have a scrollable div container fits multiple "pages" (or div's) inside of it's container.
My goal is to, at any given moment, figure out where inside my red container does it reach the top of my scrollable container. So it can be a constant on scroll event, or a button that triggers this task.
So for example. If I have a absolute div element inside one of my red boxes at top:50px. And if I scroll to where that div element reaches the top of my scrollable container. The trigger should say that I am at 50px of my red container.
I'm having a hard time grasping how to accomplish this but I've tried things like:
$("#pageContent").scroll(function(e) {
console.log($(this).scrollTop());
});
But it doesn't take into account the separate pages and I don't believe it it completely accurate depending on the scale. Any guidance or help would be greatly appreciated.
Here is my code and a jsfiddle to better support my question.
Note: If necessary, I use scrollspy in my project so I could target which red container needs to be checked.

percent = maxWidth / PAGEWIDTH;

});
$(".trimSpace").css('width', (PAGEWIDTH * percent) + 'px');
$("#formBox, .trimSpace").css('height', ($("#formScale").height() * percent) + 'px');
}
zoomProject();
resize();
EDIT:
I don't think I am conveying a good job at relaying what I want to accomplish.
At the moment there are two .formContainer's. When I scroll #pageContainer, the .formContainer divs move up through #pageContainer.
So what I want to accomplish is, when a user clicks the "ME" button or #click (as shown in the fiddle below), I'd like to know where in that particular .formContainer, is it touching the top of #pageContainer.
I do use scroll spy in my real world application so I know which .formContainer is closest to the top. So if you just want to target one .formContainer, that is fine.
I used these white div elements as an example. If I am scrolling #pageContainer, and that white div element is at the top of screen as I am scrolling and I click on "ME", the on click trigger should alert to me that .formContainer is touching the top of #pageContainer at 50px from the top. If, the the red container is just touching the top of #pageContainer, it should say it is 0px from the top.
I hope that helps clear up some misconception.
Here is an updated jsfiddle that shows the kind of action that I want to happen.

I am giving this a stab because I find these things interesting. It might just be a starting point since I have a headache today and am not thinking straight. I'd be willing to bet it can be cleaned up and simplified some.
I also might be over-complicating the approach I took, getting the first visible form, and the positioning. I didn't use the getBoundingClientRect function either.
Instead, I approached it trying to account for padding and margin, using a loop through parent objects up to the pageContent to get the offset relative to that element. Because the form is nested a couple levels deep inside the pageContent element you can't use position(). You also can't use offset() since that changes with scroll. The loop approach allowed me to factor the top margin/padding in. I haven't looked at the other solutions proposed fully so there might be a shorter way to accomplish this.
Keeping in mind that the scale will affect the ACTUAL location of the child elements, you have to divide by your scale percentage when getting the actual location. To do that I moved the scalePercentage to a global var so it was usable by the zoom function and the click.
Here's the core of what I did. The actual fiddle has more logging and junk:
var visForm = getVisibleForm();
var formTop = visForm.position().top;
var parents = visForm.parentsUntil('#pageContent');
var truOffset = 0;
parents.each(function() {
truOffset -= $(this).position().top;
});
// actual location of form relative to pageContent visible pane
var formLoc = truOffset - formTop;
var scaledLoc = formLoc / scalePercent;
Updated Fiddle (forgot to account for scale in get func): http://jsfiddle.net/e6vpq9c8/5/

If I understand your question correctly, what you want is to catch when certain descendant elements reach the top of the outer container, and then determine the position of the visible "page" (div with class formContainer) relative to the top.
If so, the first task is to mark the specific elements that could trigger this:
<div class='triggerElement' style="position:absolute;top:50px;left:100px;width:450px;height:25px;background-color:#fff;color:#000;">When this reaches the top, the "trigger" should say 50px"</div>
Then the code:
// arbitrary horizontal offset - customize for where your trigger elements are placed horizontally
var X_OFFSET = 100;
// determine once, at page load, where outer container is on the page
var outerContainerRect;
$(document).ready(function() {
outerContainerRect = $("#pageContent").get(0).getBoundingClientRect();
});
// when outer container is scrolled
$("#pageContent").scroll(function(e) {
// determine which element is at the top
var topElement = $(document.elementFromPoint(outerContainerRect.left+X_OFFSET, outerContainerRect.top));
/*
// if a trigger element
if (topElement.hasClass("triggerElement")) {
// get trigger element's position relative to page
console.log(topElement.position().top);
}
*/
var page = topElement.closest(".formContainer");
if (page.length > 0) {
console.log(-page.get(0).getBoundingClientRect().top);
}
});
EDIT: Changed code to check formContainer elements rather than descendant elements, as per your comment.
http://jsfiddle.net/j6ybgf58/23/
EDIT #2: A simpler approach, given that you know which formContainer to target:
$("#pageContent").scroll(function(e) {
console.log($(this).scrollTop() - $("#xzOwqphM4GGR_1").position().top);
});
http://jsfiddle.net/rL4Ly3yy/5/
However, it still gives different results based on the size of the window. This seems unavoidable - the zoomProject and resize functions are explicitly resizing the content, so you would have to apply the inverse transforms to the number you get from this code if you want it in the original coordinate system.

I do not fully understand what it is that you are needing, but if i am correct this should do the trick
$("#pageContent").scroll(function(e) {
// If more then 50 pixels from the top has been scrolled
// * if you want it to only happen at 50px, just execute this once by removing the scroll listener on pageContent
if((this.scrollHeight - this.scrollTop) < (this.scrollHeight - 50)) {
alert('it is');
}
});
ScrollHeight is the full height of the object including scrollable pixels.
ScrollTop is the amount of pixels scrolled from the top.

You can use waypoints to detect the position of divs based on where you're scrolling.
Here is a link to their official website's example: http://imakewebthings.com/waypoints/shortcuts/inview/

Bring an element to top of the page even if the page does not scroll

Background:
Let's say you have a simple page which has a logo and a heading only and one paragraph
<img src="http://blog.stackoverflow.com/wp-content/uploads/StackExchangeLogo1.png">
<h1>Foo Bar</h1>
<p>ABC12345</p>
This is how that looks like
That page, obviously would not have vertical overflow / scroll bar for almost even tiny scale mobile devices, let alone computers.
Question
How can you bring that heading to the top left of the screen and move the logo out of focus unless someone scrolls up? Open to using any JavaScript library and any CSS framework
Attempts:
Tried using anchors but they only work if the page already had a scroll bar and anchor was out of focus.
Tried window.scrollTo but that also requires the page to have scroll already
Tried $("html, body").animate({ scrollTop: 90}, 100); but that also doesn't work when the page doesn't have overflow
Notes:
Please note that adding some extra <br/> to induce an overflow is not the way to go, it can be done that way but that's a very ordinary workaround
Why is it needed?
Its for a form for mobile devices, simple requirement is to take the first field of the form to top of the page and hide the logo (one can scroll up if they wish to see it) so it doesn't take attention away. Not using jQueryMobile for this particular task.

If you want the user to be able to scroll up and see the logo, then the logo must be within the top boundary of the body tag, because anything outside of that tag will not be viewable. This means you cannot use negative margins or offsetting like that. The only way to achieve this is to have the page scroll to the desired location that is within the top boundary of the body tag. You can set the time for this event to one millisecond, but there will still be a 'jump' in the page when it is loaded. So, the logic is: first make sure the page is long enough to scroll to the right place, then scroll there.
//Change the jQuery selectors accordingly
//The minimum height of the page must be 100% plus the height of the image
$('body').css('min-height',$(document).height() + $('img').height());
//Then scroll to that location with a one millisecond interval
$('html, body').animate({scrollTop: $('img').height() + 'px'}, 1);
View it here.
Alternatively, you can load the page without the image in the first place. Then your form field will be flush with the top of the document. Then you could create the element at the top and similarly scroll the page again. This is a round-a-bout way of doing the same thing though. And the page will still 'jump,' there is no way around that.

Only CSS and anchor link solution
With a pseudo element :
--- DEMO ---
First :
set : html,body{height:100%;}
Second :
Choose one of your existing tags. This tag mustn't have a relatively positioned parent (except if it is the body tag). Preferably the first element in the markup displayed after the logo. For your example it would be the h1 tag. And give it this CSS :
h1:before {
content:"";
position:absolute;
height:100%;
width:1px;
}
This creates an element as heigh as the viewport area. As it is displayed under the logo, the vertical scroll lenght is the same as the logo height.
Third :
Give the first element after logo an id (for this example I gave id="anchor").
Then you can use a link like this your_page_link#anchor and you will automaticaly scroll to the anchor (logo outside/above the viewport).
This works whatever height the logo is.

Full code :
HTML
<img src="http://blog.stackoverflow.com/wp-content/uploads/StackExchangeLogo1.png">
<h1 id="anchor">Foo Bar</h1>
<p>ABC12345</p> Anchor link
CSS
html, body {
height:100%;
margin:0;
padding:0;
}
h1:before {
content:"";
position:absolute;
width:1px;
left:0;
height:100%;
}

You might need to add js functionality to hide the logo if user scrolls down but I guess following code will fullfill the first requirement.
Please see
<script src="js/jquery.js"></script>
<img id='logo' src="http://blog.stackoverflow.com/wp-content/uploads/StackExchangeLogo1.png" style="display:none">
<h1>Foo Bar</h1>
<p>ABC12345</p>
<script type="text/javascript">
var p = $( "p:first" );
var isScrolled=false;
/* For Firfox*/
$('html').on ('DOMMouseScroll', function (e) {
isScrolled = true;
if(p.scrollTop()==0 && isScrolled==true){
$('#logo').css('display','block');
}
});
/* For Chrome, IE, Opera and Safari: */
$('html').on ('mousewheel', function (e) {
isScrolled = true;
if(p.scrollTop()==0 && isScrolled==true){
$('#logo').css('display','block');
}
});
</script>
I have referred this question to find solution.

You could use touchmove event to detect swipe up or down. This is my example. You can try it on mobile device.
<style>
#logo {
position: absolute;
top: -100%;
-webkit-transition: top 0.5s;
-moz-transition: top 0.5s;
-ms-transition: top 0.5s;
-o-transition: top 0.5s;
transition: top 0.5s;
}
#logo.show {
top: 0;
}
</style>
<script>
var perY;
var y;
$(window).on('touchmove', function(e) {
e.preventDefault();
y = window.event.touches[0].pageY;
if(!perY)
perY = y;
else
{
if(y > perY)
$('#logo').addClass('show');
else
$('#logo').removeClass('show');
perY = null;
}
});
</script>
<img id="logo" src="http://blog.stackoverflow.com/wp-content/uploads/StackExchangeLogo1.png">
<h1>Foo Bar</h1>
<p>ABC12345</p>

This is the same problem i've encountered hiding the addressbar without the page overflowing. The only solution that fitted my needs was the following:
Set the min-height of the body to the viewportheight + your logo.
$('body').css('min-height', $(window).height() + 200);

This is a simple solution of getting the height of the contents to see if we can scroll to the part of the header, if not, we add height to the paragraph.
<img id="img" src="http://blog.stackoverflow.com/wp-content/uploads/StackExchangeLogo1.png" />
<h1 id="h" >Foo Bar</h1>
<p id="par" style="background:yellow;">
hello world
</p>
script:
function hola(){
var imgH = $("#img").outerHeight(true);
var titleH = $("#h").outerHeight(true);
var winH = $(window).height();
var parH = $('#par').outerHeight(true);
var contH = (imgH + titleH + parH);
var wishH = (imgH + winH);
console.log("wished height: " + wishH);
console.log("window height: " + winH);
console.log("content height: " + contH);
if(contH < wishH){
console.log("window is smaller than desired :(");
var newH = wishH - contH;
$("#par").height(parH + newH);
$(window).scrollTop(imgH);
}
}

Scrolling a DIV to Specific Location

There is a plethora of similar questions around but none of them seem to be looking for what I'm looking for, or else none of the answers are useful for my purposes.
The jsfiddle: http://jsfiddle.net/tumblingpenguin/9yGCf/4/
The user will select an option and the page will reload with their option applied. What I need is for the "option list" DIV to be scrolled down to the selected option such that it is in the center of the option list.
The HTML...
<div id="container">
<a href="#">
<div class="option">
Option 1
</div>
</a>
<!-- other options -->
<a href="#">
<div class="option selected"> <!-- scroll to here -->
Option 4
</div>
<!-- other options -->
<a href="#">
<div class="option">
Option 7
</div>
</a>
</div>
The selected option is marked with the selected class. I need to somehow scroll the DIV down to the selected option.
The CSS...
#container {
background-color: #F00;
height: 100px;
overflow-x: hidden;
overflow-y: scroll;
width: 200px;
}
a {
color: #FFF;
text-decoration: none;
}
.option {
background-color: #c0c0c0;
padding: 5px;
width: 200px;
}
.option:hover {
background-color: #ccc;
}
.selected {
background-color: #3c6;
}
I've seen this done on other websites so I know it's possible—I just haven't a clue where to begin with it.
P.S. jQuery solutions are acceptable.

Something like this http://jsfiddle.net/X2eTL/1/:
// On document ready
$(function(){
// Find selected div
var selected = $('#container .selected');
// Scroll container to offset of the selected div
selected.parent().parent().scrollTop(selected[0].offsetTop);
});
Without the jQuery (put this at the bottom of the < body > tag:
// Find selected div
var selected = document.querySelector('#container .selected');
// Scroll container to offset of the selected div
selected.parentNode.parentNode.scrollTop = selected.offsetTop;
demo: http://jsfiddle.net/66tGt/

Since you said JQuery answers are acceptable, here's an example of what you're looking for:
$('body, html').animate({ scrollTop: div.offset().top-210 }, 1000);
Replace div for whatever element you want to scroll to.

Here is one possible solution that may work for you:
Demo Fiddle
JS:
$('#container').scrollTop( $('.selected').position().top );

Take a look at this fiddle : http://jsfiddle.net/9yGCf/8/
As requested it scrolls to the middle of the div (you can change the offset by however much you want to make little adjustments). I would probably suggest setting either a line height with some padding and whatnot and then do the math to change the offset that I have at -40 so that it does put it in the middle.
But I used jquery and came up with this quick little code... also added some code to change the selected option
$('.option').click(function(){
$('.selected').removeClass('selected');
$(this).addClass('selected');
$(this).parent().parent().scrollTop(selected[0].offsetTop - 40);
});

This magical API will automatically scroll to the right position.
element.scrollIntoView({ block: 'center' })

Slide gallery with image tooltips, images breaking out of unlimited width block

I'm trying to develop a slide gallery with image tooltips according to this design:
What I need to develop is a slider controlled by two buttons, each time a button is pressed the slider's content must move a width of the slider or the width of the content left on that side, whichever is smaller. Upon mouse entering an image inside the slider the full-size version must be displayed as a tooltip.
Here's a fiddle of my solution so far, the problem I'm having is that images that don't fully fit into view plus the hidden area to the left get moved to a new line. You can see the problem by clicking the
"Show content size" button, the width of the content element will be equal to the width of the container element + content element's margin-left.
Bonus points if you can suggest an algorithm for moving the content to the right, I've got left figured out to a T (or so I think, anyway), but right is going to take a little more work (it doesn't check whether the end of the content has been reached). Update: It seems I can't implement proper movement to the right until the other issue is resolved, here's the algorithm I came up with, I can't measure "left to display" if I can't measure the actual width of the content element.

I created something you might like:
gallery demo
The gallery does not scroll the full gallery width by default (you can change that) cause some initially cut-off images at the right side, after a 'full' slide would result cut-off again, just on the other side of our gallery. You have for that cause the beKind variable. Adjust it as you like.
It hides the buttons if there's not enough content to make the gallery usable.
The gallery calculates the remaining space to scroll.
Once the slider end reached - the left/right buttons make the gallery jump to the beginning/end, so that are always usable. (Seems kinda weird to have a button... but that does nothing right? ;) )
The Tooltip has a hover-intent built in, to not piss off our users if they unintentionally hovered our gallery: (the tooltip fades in if the hover is registered for more that 120ms. Fair timing. I like it.)
As pointed out in your comment now the tooltip will not go off the screen.
jQ:
// Slide Kind Gallery - by roXon // non plugin v. // CC 2012.
$(window).load(function(){
var galW = $('#gallery').outerWidth(true),
beKind = 120, // px substracted to the full animation to allow some images to be fully visible - if initially partly visible.
sumW = 0;
$('#slider img').each(function(){
sumW += $(this).outerWidth(true);
});
$('#slider').width(sumW);
if(sumW <= galW){ $('.gal_btn').remove(); }
function anim(dir){
var sliderPos = Math.abs($('#slider').position().left),
rem = dir ==='-=' ? rem = sumW-(sliderPos+galW) : rem = sliderPos,
movePx = rem<=galW ? movePx = rem : movePx = galW-beKind;
if( movePx <= 10){
movePx = dir==='-=' ? movePx=rem : movePx = galW-sumW;
dir = '';
}
$('#slider').stop(1).animate({left: dir+''+movePx },1000);
}
$('.gal_btn').on('click', function(){
var doit = $(this).hasClass('gal_left') ? anim('+=') : anim('-=');
});
});
And the tooltip script:
// Addon // Tooltip script
var $tt = $('#tooltip');
var ttW2 = $tt.outerWidth(true)/2;
var winW = 0;
function getWW(){ winW = $(window).width(); }
getWW();
$(window).on('resize', getWW);
$('#slider img').on('mousemove',function(e){
var m = {x: e.pageX, y: e.pageY};
if( m.x <= ttW2 ){
m.x = ttW2;
}else if( m.x >= (winW-ttW2) ){
m.x = winW-ttW2;
}
$tt.css({left: m.x-ttW2, top: m.y+10});
}).hover(function(){
$clon = $(this).clone();
var t = setTimeout(function() {
$tt.empty().append( $clon ).stop().fadeTo(300,1);
},120);
$(this).data('timeout', t);
},function(){
$tt.stop().fadeTo(300,0,function(){
$(this).hide();
});
clearTimeout($(this).data('timeout'));
});

Hope you'll like it, and you learned some useful UI design tricks.
By the way, if you want to populate your ALT attributes (Search engines like it!) you can also grab that text and make it appear inside the tooltip like here!:
demo with text inside the tooltip
Happy coding.

I don't know if I understand correctly your problem. If you set a width wide enough to .scroll-content div, images wouldn't go to the "next line". So a solution would be to set a width with css. If not, you could use jquery to determine the total width of all the images and give it to the .scroll-content div. Calculate total width of Children with jQuery

Click button and Side Menu slide out from hidden

I want to make a similar navigation menu like what m.facebook.com did.
but this, i want to make it nicely animated slide out from left side of the website.
Flow ::
Click a button > (Menu is hidden by default) Menu Slide out, push the main container to right a bit to fit the menu > Click again > Menu Slide in and hidden again.
I got no idea to make it with javascript or jquery or ajax while i'm new to web development and there are too much of effect scripting language. May i know to achieve this, which is perfect in smoothness ?

Something along these lines... http://jsfiddle.net/HfdXY/
HTML:
<div id="menu">Menu</div>
<button id="openMenu">Toggle menu</button>​
CSS:
#menu {
height: 300px;
width: 0px;
border: 1px solid black;
display: none;
}​
JS:
$("#openMenu").click(function() {
var menu = $("#menu");
if ($(menu).is(":visible")) {
$(menu).animate({width: 0}, 1000, function() {$(menu).hide();});
} else {
$(menu).show().animate({width: 100}, 1000);
}
});​
