How to slowly move header while user scrolls the page? - javascript

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
}
});

Infinite Scroll Effect with javascript

anyone have a clue how to make a sroll effect like this?
http://www.eurekasoft.com
I know the content is repeated at the end to create the illusion but i would like to know how to achieve the seemingly never end scroll.
Thanks!
It appears that site is using Skrollr: http://prinzhorn.github.io/skrollr/
Scroll all the way down for links to the Github and more examples.
Deep down, it is using the function window.scrollTo() to set the scroll position, and probably setting DOM around that area so that it looks the same as where it was scrolled from.
https://github.com/Prinzhorn/skrollr/blob/master/src/skrollr.js#L617
This works for me :)
here is the example: http://www.cancerbero.mx (only enable in Chrome and Safari)
// #loop is the div ID where repetition begins
$(document).ready(function(){
$(window).scroll(function(){
var scroll = $(window).scrollTop();
var limit = $('#loop').position().top;
if(scroll >= limit){
window.scrollTo(0,1); // 1 to avoid conflicts
}
if(scroll == 0){
window.scrollTo(0,limit);
}
});
});

Using javascript to pause background scroll to allow for fixed elements to have slide show

Ok so the effect I am trying to emulate can be found on the nexus 5 site - http://www.google.com/nexus/5/ - when you scroll to the phone section. I've viewed source and looked through the code but there is over 13k lines of js so it was a waste.
Anyways what I did was add a class to fix the position of the images and created a background div that was like 5000px so it would appear to be fixed. The js fixed the position after the screen reached a certain point and then removed the fixed class after the end of the div.
My question is that i know this can be done better than my janky 'hack'. I'd love to hear your thoughts on better implementation.
This is part of the code that adds the fixed class
<script type="text/javascript">
$(window).scroll(function() {
var scroll = $(window).scrollTop();
if (scroll >= 500) {
$(".container").addClass("fixed");
}
if (scroll >= 8000) {
$(".container").removeClass("fixed");
}
});

Haven't done something like this before myself however. Also just a note that fixed position elements from my experience act up when viewed on tablet/smartphone.

Jquery Sticky Nav Issue

I'm been trying to get my head around issue and seem to cant find some help.
http://fiddle.jshell.net/DQgkE/7/show/
The experience is a bit jumpy and buggy now- but what i will like is
1) When you scroll down the page. I want the Sticky Nav to be (disable,dropped off, stop) at a specific location(chapter-3) on the page and the user should have the ability to keep scrolling down.
2) When the user is scrolling back up, the code will stick the nav back and carry it up until the nav reaches the original position at the top.
Below is a starting point.
3) Currently is kinda of doing that but there's some huge jump going on when scrolling back up
http://imakewebthings.com/jquery-waypoints/#doc-disable
using disable, destroy, enable option will be nice.
This is a original experience cleaned: http://fiddle.jshell.net/DQgkE/1/show/
Thanks for the help in Advance.
I'm not sure how this plugin you used work, but I have a solution I wrote a while back that I wrote in jquery. It has few variables at the top, the item you wanted sticky, the item where you want it to stop, and the class to add when it becomes sticky and padding at the top and bottom. I only modified the javascript portion in this fork.
EDIT
I went ahead and fixed the original code. Solution without waypoint plugin is in comments.
Here is the result:
http://fiddle.jshell.net/Taks7/show/
I would recommend to use jQuery (that was a surprise, right?! :P)
$(document).ready(function() { //when document is ready
var topDist = $("nav").position(); //save the position of your navbar !Don't create that variable inside the scroll function!
$(document).scroll(function () { //every time users scrolls the page
var scroll = $(this).scrollTop(); //get the distance of the current scroll from the top of the window
if (scroll > topDist.top - *distance_nav_from_top*) { //user goes to the trigger position
$('nav').css({position:"fixed", width: "100%", top:"*distance_nav_from_top*"}); //set the effect
} else { //window is on top position, reaches trigger position from bottom-to-top scrolling
$('nav').css({position:"static", width:"initial", top:"initial"}); //set them with the values you used before scrolling
}
});
});
I really hope I helped!

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.
Greetings.

scrolling effect

I'm trying to do something like this.
http://www.mini.jp/event_campaign/big-point/
What I can't figure out is how to make the animation happen based on the scroll when the scroll hits a specific position. I have similar blocks of content that I only want to animate parts of it based on the scroll and when the block is within the browsers view area when scrolling.
I understand using the scroll event to get the scrollTop position I'm more concerned with how everything else would work.
$(window).bind('scroll',function(e){
var scrolledY = $(window).scrollTop();
});
Anyone can help explain some of this.
Thanks
Just like what MiniGod said in the comment, look in to the source code (animate.js), and you can see that they have recorded all the "scenes" and all other things like alpha and pos for everything.
// scene 1
{
scene:"#scene1",
name:".car",
runStatus:[
{p:10,pos:true,x:275,y:240,alpha:true,opacity:1,scale:true,orgSize:[475,270],scaleSize:1},
{p:180,pos:true,x:275,y:200,alpha:true,opacity:1,scale:true,orgSize:[475,270],scaleSize:1},
{p:270,pos:true,x:275,y:140,alpha:true,opacity:1,scale:true,orgSize:[475,270],scaleSize:1},
{p:500,pos:true,x:275,y:-300,alpha:true,opacity:0,scale:true,orgSize:[475,270],scaleSize:1}
]
}
