Divs don't stop following scroll at footer

I tried a lot of solutions but I cant make the divs stop following the scroll at the footer.
Here is my code to make the divs follow the scroll (colderecha and colizquierda are my divs that follow the scroll):
$(document).ready(function () {
var top = $('#colizquierda').offset().top - parseFloat($('#colizquierda').css('marginTop').replace(/auto/, 0));
$(window).scroll(function (event) {
var y = $(this).scrollTop();
//if y > top, it means that if we scroll down any more, parts of our element will be outside the viewport
//so we move the element down so that it remains in view.
if (y >= top) {
var difference = y - top;
$('#colizquierda').css("top",difference);
}
});
});
$(document).ready(function () {
var top = $('#colderecha').offset().top - parseFloat($('#colderecha').css('marginTop').replace(/auto/, 0));
$(window).scroll(function (event) {
var y = $(this).scrollTop();
//if y > top, it means that if we scroll down any more, parts of our element will be outside the viewport
//so we move the element down so that it remains in view.
if (y >= top) {
var difference = y - top;
$('#colderecha').css("top",difference);
}
});
});
What I have tried:
$(document).scroll(function() {
checkOffset();
});
function checkOffset() {
if ($('#colizquierda').offset().top + $('#colizquierda').height() >= $('#footer').offset().top - 10)
$('#colizquierda').css('position', 'absolute');
if ($(document).scrollTop() + window.innerHeight < $('#footer').offset().top)
$('#colizquierda').css('position', 'fixed');
if ($('#colderecha').offset().top + $('#colderecha').height() >= $('#footer').offset().top - 10)
$('#colderecha').css('position', 'absolute');
if($(document).scrollTop() + window.innerHeight < $('#footer').offset().top)
$('#colderecha').css('position', 'fixed');
}

Sticky sidebar doesn't stop scrolling

I have a sticky sidebar on my page using the following script:
$(function() {
var offset = $("#sidebar").offset();
var topPadding = 15;
$(window).scroll(function() {
if ($(window).scrollTop() > offset.top) {
$("#sidebar").stop().animate({
marginTop: $(window).scrollTop() - offset.top + topPadding
});
} else {
$("#sidebar").stop().animate({
marginTop: 0
});
};
});
});
The problem is that it should stop scrolling when it reaches the Middle Block Div. At the moment it doesn't stop scrolling and it pushes all the rest of the content down. Is there a way to fix this?

Thank you.

You need to get the position of .middle-block and stop the sidebar from scrolling at that point (minus the height of the sidebar).
Change your jQuery function to:
$(function() {
var offset = $("#sidebar").offset();
var mbOffset = $(".middle-block").offset();
var mbPos = mbOffset.top - $("#sidebar").outerHeight() - 30; /*30px extra space*/
var topPadding = 15;
$(window).scroll(function() {
if ($(window).scrollTop() > offset.top ) {
if( $(window).scrollTop() < mbPos ) {
$("#sidebar").stop().animate({
marginTop: $(window).scrollTop() - offset.top + topPadding
});
}
} else {
$("#sidebar").stop().animate({
marginTop: 0
});
};
});
});
Updated Pen

you have check if Sidebar has been moved to Middle Box, if so just stop the sidebar to animate.
like this :
$(function() {
var offset = $("#sidebar").offset();
var boxOffset = $(".middle-block").offset().top;
var sidebarHeight = parseInt($("#sidebar").outerHeight());
var topPadding = 15;
$(window).scroll(function() {
if ($(window).scrollTop() > offset.top) {
if(($(window).scrollTop()+sidebarHeight)<boxOffset){
$("#sidebar").stop().animate({
marginTop: $(window).scrollTop() - offset.top + topPadding
});
}
} else {
$("#sidebar").stop().animate({
marginTop: 0
});
};
});
});

Scroll div until top of footer

i've been looking for this for a couple of days but still no joy!
I would like to have a div scroll in a fixed position until it gets to the top of the footer.
Here is a fiddle of what i have so far: http://jsfiddle.net/danieljoseph/uk4mC/
I'm using this JQuery code but this uses pixels to determine when the div stops. I would like to use the top of the footer as the stop point:
$(document).scroll(function() {
var scrollVal = $(document).scrollTop();
$('#floating-container').css('top',scrollVal+'px');
if (scrollVal < 50) {
$('#floating-container').css('top','50px');
}
if (scrollVal > 2347) {
$('#floating-container').css('top','2347px');
}
});
The issue is that i am using a CMS and the client will be adding text to the page so the second value will change depending on what they add.
I hope i've been clear enough! please let me know if you require more details.
Thanks,

You have to check in the scroll event if the bottom edge of your div is lower than the footer. If it is, place the div at the position of the footer minus the height of the div.
$(function(){
var container = $('#floating-container');
var minTop = $('header').outerHeight();
var maxTop = $('footer').offset().top - container.outerHeight();
$(document).scroll(function() {
var scrollVal = $(document).scrollTop();
container.css('top', scrollVal);
if (scrollVal < minTop) {
container.css('top', minTop);
}
if (container.offset().top > maxTop ) {
container.css('top', maxTop );
}
});
});
Fiddle
And, a much shorter variant of the script above:
$(function(){
var container = $('#floating-container');
var minTop = $('header').outerHeight();
var maxTop = $('footer').offset().top - container.outerHeight();
$(document).scroll(function() {
container.css('top', Math.min( Math.max(minTop, $(document).scrollTop()), maxTop ));
});
});
Short version fiddle.

Just read the position of the footers top when you load the page:
http://jsfiddle.net/uk4mC/1/
var footerTop = $('#text-block').position().top;
and then use that as a trigger:
if (scrollVal < footerTop) { }

Fixed sidebar on the scroll stop at div

I try to make sure that a div "filter" becomes fixed when scrolling and then stop when it comes down to "outside_footer_wrapper". use the following script but can not get it to work?
jsfiddle
$(function() {
var top = $('#filter').offset().top - parseFloat($('#filter').css('marginTop').replace(/auto/, 0));
var footTop = $('#outside_footer_wrapper').offset().top - parseFloat($('#outside_footer_wrapper').css('marginTop').replace(/auto/, 0));
var maxY = footTop - $('#filter').outerHeight();
$(window).scroll(function(evt) {
var y = $(this).scrollTop();
if (y > top) {
if (y < maxY) {
$('#filter').addClass('fixed').removeAttr('style');
} else {
$('#filter').removeClass('fixed').css({
position: 'absolute',
top: (maxY - top) + 'px'
});
}
} else {
$('#filter').removeClass('fixed');
}
});
});

If you want to stop the position:fixed after you reach the footer you can do something like this faking with the top:
$(function() {
var top = $('#filter').offset().top,
footTop = $('#outside_footer_wrapper').offset().top,
maxY = footTop - $('#filter').outerHeight();
$(window).scroll(function(evt) {
var y = $(this).scrollTop();
if (y > top) {
$('#filter').addClass('fixed').removeAttr('style');
if (y > maxY-20){
var min = y - maxY + 20;
$('#filter').css('top','-'+min+'px');
}
} else {
$('#filter').removeClass('fixed');
}
});
});
Also take in care with the CSS for the class fixed you need to make that with equal specificity of #filter I made this change:
#sidebar #filter.fixed /*Add #sidebar*/
Check This Demo Fiddle

if you know at which pixel number the filter have to be fixed and at which pixel number the footer starts you can try this function:
scrollTop

Is it something like this?
jsfiddle
// get box div position
var box = document.getElementById('box').offsetTop;
window.onscroll = function(){
// get current scroll position
var scroll_top = document.body.scrollTop || document.documentElement.scrollTop;
document.getElementById('scbox').innerText = scroll_top + ' ' + box;
// if current scroll position >= box div position then box position fixed
if(scroll_top >= box)
document.getElementById('box').style.position = 'fixed';
else
document.getElementById('box').style.position = 'relative';
}

try this:
#sidebar {
position: fixed;
}

Change top value of fixed element depending on scroll

I like to create an effect where my navigation bar hides when scrolling down, but appears when scrolling up, no matter how far you scrolled down.
I've managed to get as far as this jsfiddle, but I'm lost from there.
The navigation div has position: fixed with top: 0. I decrease the top for every number of pixels scrolled down. But at the moment, I'm not having the insight to increase top for every number of pixels scrolled UP, no matter how far down you scrolled.
I hope it's clear enough what I try to achieve.
jQuery
var topScroll = 0;
$(document).scroll(function () {
var scrolled = $(this).scrollTop();
if (scrolled > $('nav').height()) {
$('nav').css('top', ($('nav').height() - scrolled));
}
if (topScroll > scrolled) {
//scrolling up
} else {
//scrolling down
}
topScroll = scrolled;
});

Edit
I think I need a way of saving the scrollTop() value when the scroll direction is changed and then add the difference between that number and the new scrollTop() to the top value of my navbar. I just don't know how to do that.

Is this what you want ?
var lastScrollTop = 0;
$(window).scroll(function(event){
var st = $(this).scrollTop();
if (st > lastScrollTop){
$('nav').css('display', 'none');
} else {
$('nav').css('display', 'block');
}
lastScrollTop = st;
});

Similar to luidgi27's code but with a smooth animation :)
-> altered Fiddle
var lastScrollTop = 0;
$(window).scroll(function(event){
var st = $(this).scrollTop();
if (st > lastScrollTop){
$('nav').animate({height: "0px"}, 100);
} else {
$('nav').animate({height: "50px"}, 100);
}
lastScrollTop = st;
});
Edit
Im not sure what you want. Changed the Code a bit so it has steps while showing the Nav.
-> new altered Fiddle
var lastScrollTop = 0;
var height = 50;
$(window).scroll(function(event){
var st = $(this).scrollTop();
if (st > lastScrollTop && height > 0){
$('nav').animate({height: "-=25px"}, 30);
height = height - 25;
} else if(st < lastScrollTop && height < 50){
$('nav').animate({height: "+=25px"}, 30);
height = height + 25;
}
lastScrollTop = st;
});

Here you go with the third and most accurate hiding effect.
var lastScrollTop = 0;
var diffrence = 0;
var height = 50;
var isGrowing = false;
var isShrinking = false;
$(window).scroll(function(event){
var st = $(this).scrollTop();
diffrence = st - lastScrollTop;
$('#debug').html(diffrence + "<br />" + height + "<br />" + $('nav').height());
if (diffrence > 0 && height < 50 && !isGrowing){
if((diffrence + height) > 50){
height = 50;
isGrowing = true;
$('nav').stop().animate({height: "50px"}, 100, function(){
isGrowing = false;
});
}else{
height = height + diffrence;
$('nav').animate({height: "+="+diffrence+"px"}, 0);
}
} else if(diffrence < 0 && $('nav').height() > 0 && !isShrinking){
if((diffrence + height) < 0){
height = 0;
isShrinking = true;
$('nav').stop().animate({height: "0px"}, 100, function(){
isShrinking = false;
});
}else{
height = height + diffrence;
diffrence = diffrence*-1;
$('nav').animate({height: "-="+diffrence+"px"}, 0)
}
}
lastScrollTop = st;
});
