How are you?
Im using waypoints plugin for sticky elements as i scroll down the page.
However I will like to have the sticky remove at a certain position of the page, lets say 30px from its starting scroll point and then when the user scrolls up back the page, the sticky elements takes it back and up back to its original starting point:
JavaScript:
$(function() {
// Do our DOM lookups beforehand
var nav_container = $(".nav-container");
var nav = $("nav");
nav_container.waypoint({
handler: function(event, direction) {
nav.toggleClass('sticky', direction=='down');
if (direction == 'down') nav_container.css({ 'height':nav.outerHeight() });
else nav_container.css({ 'height':'auto' });
},
offset: 15
});
});
Another Example you can look at that i found online is here
http://webdesigntutsplus.s3.amazonaws.com/tuts/313_waypoints/demo/index.html
Lets just say I want the sticky nav to be dropped off at CHAPTER ONE as im scrolling down then when I'm scrolling back up it gets picked up back and carry it to the starting point.

I was trying to use this but no success.
Thanks
Any direction from Fiddle will help!

I am having an issue. Im using a one page design for a friend with a fixed floating menu on the top. The problem I encounter is that when I click on a link it scrolls down but the offset is not right. Most the of time it scrolls down a little too much covering the content below the menu. What I am trying to achieve is that the scrolling stops at the div being exactly below my menu bar. The other issue is that somehow it wont scroll down when the space between two sections is too narrow. It tries but somehow only moves a few pixels then stops. I can imagine that both are related to the offset issue.
Im sorry, english is not my native language.
Here is what I got so far. A standard scrolling function with window.location.hash. The target are divs spread across the site.
$(document).ready(function () {
$('a[href^="#"]').on('click', function (e) {
e.preventDefault();
var target = this.hash;
var t = $(this.hash).offset().top;
$('.wrapper').animate({
scrollTop: t,
}, 1000, function () {
window.location.hash = target;
});
});
});
You can see an example of the problem live: http://rolfvohs.com/
What I tried so far was using the add.class function to bind the div with an extra padding when a link is clicked. It does work in a way but creates an awkward space. I also tried placing the divs at different locations but that does not fix the job either, just messes it up further.
I would appreciate some insight.
window.location.hash = target;
moves the scroll by default to the div position and you are setting offset top before the hash change so first its changes the offset after that it move to div location.
first try after removing the line "window.location.hash = target;" from the code
or
move the "window.location.hash = target;" out side and above the "$('.wrapper').animate({})" it will work .
I am using bootstrap 3 and have a fullscreen hero unit at the top of my page, below that is my navigation. I have some js which allows my navbar to stick to be fixed at the top after you scroll past the full screen hero. Also some js for my smooth scrolling links.
The problem is the offset is different before you scroll past the full screen hero and after. But it works fine when you are past the jumbotron. I have tried a bunch of different things but I can seem to get this to work exactly.
Check out the fiddle here.
Here is my js for the smooth scrolling links:
$(document).ready(function() {
// navigation click actions
$('.scroll-link').on('click', function(event){
event.preventDefault();
var sectionID = $(this).attr("data-id");
scrollToID('#' + sectionID, 750);
});
// scroll to top action
$('.scroll-top').on('click', function(event) {
event.preventDefault();
$('html, body').animate({scrollTop:0}, 1200);
});
// mobile nav toggle
$('#nav-toggle').on('click', function (event) {
event.preventDefault();
$('#main-nav').toggleClass("open");
});
});
// scroll function
function scrollToID(id, speed){
var offSet = 95;
var targetOffset = $(id).offset().top - offSet;
var mainNav = $('#main-nav');
$('html,body').animate({scrollTop:targetOffset}, speed);
if (mainNav.hasClass("open")) {
mainNav.css("height", "1px").removeClass("in").addClass("collapse");
mainNav.removeClass("open");
}
}
if (typeof console === "undefined") {
console = {
log: function() { }
};
}
By changing var offSet = 95; I am able to adjust the offset but what would be the best way to use 180 before the navbar sticks to the top but 95 when it does?
Also here is the js I am using for my navbar:
$(function () {
/* $(".navbar-fixed-top").css({"top":$(".jumbotron").height()});
$(window).resize(function (e) {
$(".navbar-fixed-top").css({"top":$(".jumbotron").height()});
});*/
$(document).on( 'scroll', function(){
console.log('scroll top : ' + $(window).scrollTop());
if($(window).scrollTop()>=$(".jumbotron").height())
{
$(".navbar").addClass("navbar-fixed-top");
}
if($(window).scrollTop()<$(".jumbotron").height())
{
$(".navbar").removeClass("navbar-fixed-top");
}
});
});
Are you open to angular.js? I have a directive i use for this. As seen here.
I'll grab the plunker link for you. you might find the code helpful.
Essentially you need to create a ghost dom element to take the place of the menu when you pull it to an new layout position.
EDIT: Here it is
I won't suggest grabbing angular just for this. But you can use the basis of the events and logic to build your own solution.
This here is creating an element and placing in its place
$scope.spacer = $element.after(
'<div class="spacer" style="height:' + $element[0].clientHeight + 'px"> </div>').next();
then this element is removed when the menu is back to its static position.
Inspect the dom and watch how it changes, this will probably help you see the events and changes that need to take place.
EDIT 2 SOLUTION:
HERE is the concepts applied to your JSFiddle
It's not the best solution but by adding margin: 0 0 -100px 0; to your .navbaryou lose the spacing issue.
Also you're getting 22 console errors because of missing images. I'm not saying that this is causing any major problems but you would be better off losing them.
The problem is that when you have not scrolled past the hero, navigation is still part of the layout and pushes content bellow it a little lower. When you scroll past (either manually or via a script) the hero, navigation is removed and fix positioned. That makes everything which was bellow to "jump up" exactly of the navigation height.
That means if portfolio was 1000px from the top, on click you say: go 1000px from top; but then porfolio moves 100px up (as explained above) meaning it is now 900px from the top while the window scrolled 1000px as you asked.
When you have scrolled past the hero, nothing changes its position.
I'm been trying to get my head around issue and seem to cant find some help.

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!
This question already exists:
jQuery Waypoints Plugin

How are you? - I'm using imakewebthings.com/jquery-waypoints to move nav element down the page. How ever I will like to un-stick the nav element at a specific segment of my page and then when scrolling back up for it to stick it back and carry it to its original spot- maybe 30pixcel after scrolling down.
Any help will be appreciated.
If I understand you're wanting an element to stick when it passes a certain threshold, and return to fixed when it goes above that?
if so - check out http://drewdahlman.github.io/Pinned/ this will do exactly what you're wanting. it's an easy to use plugin.
$("#element").pinned({
bounds: 30, // when to become sticky
scrolling: 0, // position during scroll
});
it will return to its original position after it's above 30 and stick when it hits 30px. Make sure you set it's default position to absolute.
Good luck!
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.
