jquery $(window).scroll bottom and make div visible not working

Hi i try to display a div when i scroll to bottom of my page and hide it when its not on the bottom.
The alert message work when at the bottom page but setting css visible or trying with fadeIn or out not work. I need little help to see what i did wrong.
Also on IE 9 the div "#loadSection" its hidden but i still able to put my cursor on it and click when other browser work correctly.
here my code.
$(window).scroll(function() {
if ($(window).scrollTop()+$(window).height() > $(document).height()){
$("#loadSection").fadeTo(0,0).css('visibility','visible');
alert("bottom");
}else{
$("#loadSection").fadeTo(0,0).css('visibility','hidden');
}
});

The problem is that the fadeIn/Out happens with every bit of scroll and it's causing the div to flash. Here's a CSS animated option:
$(window).scroll(function() {
if ($(window).scrollTop()+$(window).height() >= $(document).height()){
$("#loadSection").addClass('visible');
}else{
$("#loadSection").removeClass('visible');
}
});
DEMO:

The visibility property allows an element to remain on the page and take up space. To solve your issue in IE where you're still able to mouse over it, use the display property instead.
To your main issue, try the following:
var loadsection = $("#loadSection");
if ($(window).scrollTop() >= $(document).height() - $(window).height()){
if ( loadsection.is(':hidden') ) loadsection.fadeIn();
}else{
if ( loadsection.is(':visible') ) loadsection.fadeOut();
}
fadeIn and fadeOut will utilize the display property, which will completely remove the element when it's not visible. Also, you're fading to zero opacity in both of your fadeTo calls, so even if though visibility is being set, the element is still completely transparent.

fixed div while scrolling which moves other elements in a menu

I have some menu items on the right hand side of my website that are: -
Basket Summary
Best Sellers
Quick Links
etc
I want the basket summary to follow down the page as the page is scrolled, I know how to this using position: fixed, but I need it to also move the other elements out of the way otherwise it will just overlap them.
I was looking at this: jsfiddle which would do the job and works but obviously thats only on button click, I would need to adapt this to scroll via jQuery.
I have read many tutorials for floated fixed divs but they are all for one div and don't have any other divs to interact with.
Any ideas if possible and/or how to do it?
Code from js fiddle as follows: -
$(function() {
$('.upButton').click(function(e){
var $parent = $('.highlight').closest('.box');
$parent.insertBefore($parent.prev());
});
$('.downButton').click(function(e){
var $parent = $('.highlight').closest('.box');
$parent.insertAfter($parent.next());
});
});

Is this what you're looking for?: http://jsfiddle.net/cmontgomery/YVh4q/
essentially, whenever the window scrolls check to see if your section is in the visible area and if not, adjust accordingly:
$(window).scroll(function () {
var mover = $("#sidebar .quick-links");
if($(window).scrollTop() === 0) {
//console.log("to top");
mover.prependTo("#sidebar");
} else if(!isFullyInViewableArea(mover)) {
var parent = mover.closest('.section');
if(isBelowViewableArea(mover)) {
//console.log("moving up");
parent.insertBefore(parent.prev());
} else {
//console.log("moving down");
parent.insertAfter(parent.next());
}
}
});
I must admit, this solution is not the best user experience, i.e. it jumps instead of scrolling smoothly. If it were me I would put the movable section as the last item in the right column and move that down the page with absolute positioning so it follows the top of the view-able area exactly.

Use this
Drag & Drop is best.

How to slowly move header while user scrolls the page?

I want to achieve the effect that is used on this Header on this example website:
http://anchorage-theme.pixelunion.net/
You will notice that as you scroll the page, the header slowly moves upward until it disappears from view. I want to achieve this same effect. I believe it will need some JS and CSS positioning but still have no clue how to achieve this. Is this done with parallax scrolling?
Would appreciate if someone could give me a quick example of the code used to do this with a element. So I can then use it on my own site.
Cheers.

the $(window).scroll(function () {...}) is the one you need here
$(document).scrollTop() is the amount of scrolled distance from the top

Use this:
$(window).scroll(function(){
if ($(this).scrollTop() > x){ // x should be from where you want this to happen from top//
//make CSS changes here
}
else{
//back to default styles
}
});

Animate a div after scrolling away from the top of the webpage

I'm currently trying to make a div appear from behind another div after the user scrolls away from the top of the page.
I'm hoping to do this using animate so that it slides out. Like this...
http://jsfiddle.net/xaYTt/99/
But I can't figure out how to make the red box stay behind the blue box until the user scrolls away from the top of the page.
I also need to reverse this when the user scrolls back up to the top of the page, so the red box slides back under the blue box again.
Can anyone help me out?

This is not the most elegant solution, but it works nonetheless.
http://jsfiddle.net/37LZ5/
Components:
Use $(document).scroll as a trigger to know when scrolling
Use scrollTop() to know how far we're scrolling (0 = top)
Remember state to make sure animation doesn't get triggered a zillion times (var away)
Use .stop() to prevent weird behaviour when halfway through one animation, another animation gets triggered

I think you are looking for this take a look at this demo
Working demo
Code
$(document).ready(function(){
//$('#bottom-box').animate({'margin-top': '200px'}, 1500);
$('body').hover(function(){
$('#bottom-box').animate({'margin-top': '200px'}, 1500);
}, function(){
$('#bottom-box').animate({'margin-top': '50px'}, 1500);
});
});

If my understanding about your question is correct, this is what you are looking for
Since you said, "User scrolls away from the top of the page", I added a div to be at the top of the page.
var isAlreadyOut=false;
$("#divPageTop").mouseover(function(){
if( isAlreadyOut==true)
{
$('#bottom-box').animate({'margin-top': '60px'}, 1500);
isAlreadyOut=false;
}
else
{
$('#bottom-box').animate({'margin-top': '200px'}, 1500);
isAlreadyOut=true;
}
});
Here is the jsfiddle version
http://jsfiddle.net/xaYTt/103/

I did something with jsFiddle that might be what you are after, if I understood your question correctly.
Basically, the red box will animate when you scroll the window more than the distance of the blue box.
Not 100%, just a quick mock up to see if that's what you want.
(When you scroll, click on the scroll bar arrows for more accurate results)

jQuery scrolling UL with hidden overflow

I have a UL with LI's set to display horizontally. The UL has a fixed width and it's set to hide the overflow. This is so I can display my images, which are to be used in a gallery, neatly. It works and looks nice.
I want to, however, use jQuery to scroll the contents of the UL rather than set the overflow property to auto and be presented with those ugly scroll bars. I recycled some code I used to do the same thing a few weeks back but, back then, I was doing it in DIV's. Much easier, apparently.
$('.gallery_container span').hover(
function()
{
if ($(this).attr('class') == 'up')
direction = '-=';
else
direction = '+=';
var divOffset = $('ul.gallery').offset().top;
$('ul.gallery').animate({scrollTop: direction + divOffset}, 5000);
},
function()
{
$('ul.gallery').stop();
});
I saw a site that says the scrollTop property can be applied to UL's. So I'm not sure what exactly is causing this not to work.
Any ideas?
EDIT: Found what was causing it to not work at all but not it scrolls vertically - Kind of expected that. Is there any way to scroll it horizontally?

Perhaps:
$('ul.gallery').animate({scrollLeft: direction + divOffset},2000);
