I am building a Parallax website using SuperScrollorama which have some animation frame by frame using jquery and css3...
But after ending up doing so i am stuck in a problem, i am trying to navigate the pages using some scroll plugin...
I have tried Basic jquery using scrollTop event, using Jquery ScrollTo and using Tween Lite ScrollTo plugin to navigate through pages but nothing seems to work...
The issue i get after goggling it is if pages are pinned together as position:fixed; and pages doesnot scroll to that position and stuck between...
With Jquery ScrollTo, my code:-
$('.menus a').click(function(e){
e.preventDefault();
$.scrollTo(this.hash, 2000, {
easing:'easeInOutExpo',
offset:3000,
axis:'y',
queue:true
});
});
With basic scrollTop jquery, my code:-
$('a').bind('click',function(event){
var $anchor = $(this);
$('html, body').stop().animate({
scrollTop: $($anchor.attr('href')).offset().top
}, 1500,'easeInOutExpo');
event.preventDefault();
});
Currently my code works like this:- http://jsfiddle.net/tFPp3/6/
As you can see in my demo, the scroll stuck between before reaching the exact position through hash...
What is the solution if i have to play through the pinned elements in Superscrollorama?
You'll have to do 2 animations : one to reach the ancher offset and then, after superscrollorama added new element for animation and recalculate the document height, do the second animation to reach the correct key frame on that page (that you fixed at offset 3000 of that section).
$(function(){
var hashes = [];
$('.menus a').each(function(){
hashes.push(this.hash);
});
console.log('hashes:', hashes);
$('.menus a').click(function(e){
e.preventDefault();
var h = this.hash;
var pageTop = $(h).offset()['top'];
console.log('pageTop=',pageTop);
$.scrollTo( pageTop+1, 2000, {
easing:'easeInExpo',
axis:'y',
onAfter:function(){
setTimeout(function(){
console.log('hashes:', hashes);
var id = hashes.indexOf(h);
console.log('hashes['+(id+1)+']=', hashes[(id+1)]);
var nextPageTop = $(hashes[id+1]).offset()['top'];
console.log('nextPageTop=', nextPageTop);
var keyOffset = pageTop + 3000;
console.log('keyOffset=',keyOffset);
if(keyOffset < nextPageTop ){
$.scrollTo( keyOffset, 2000, {
easing:'easeOutExpo',
axis:'y'
});
}
},100);
}
});
});
});
Note that each section offset changes constantly so, before launching the second animation, we have to test that we are not scrolling till the next section again. We also need a little delay here to let superscrollorama make its sauce before testing respective offsets (saddly it doesn't seem to provide an event to do so).
I had the same issue as you. Here's how I went about fixing it....
First of all we know that Superscrollorama adds a spacer pin before your element, it sets the height of the element which defines how long the user has to scroll through a section (the duration)....So in theory all we have to do is add up all the pin heights that happen BEFORE the element you want to scroll to and then offset from the top of that element...
What I did was....
Find out what element you want to scroll to. Check how many supersrollorama-pin-spacers there are before that pin, work out the heights of all of the pins and then offset it to your initial scrollTo function.
pin = $('#pin-id').prev(); //find the spacer pin
prevPin = pin.prevAll('.superscrollorama-pin-spacer'); //find all the pins before this
heights = []; //create an array to store the pin heights
$.each(prevPin, function( index, value ) {
value = $(this).attr('height'); //get each height
heights.push(value); // push it to array
});
//use eval to join all the heights together
heights = eval(heights.join("+"));
Now we have the height so lets scroll to it.....
TweenMax.to($('html,body'),1, { scrollTop:heights, });
Good Luck! I hope this helps you.
I have had a similar issue and found that janpaepke on the superscrollorama project added an additional toggle to make this easier.
You can manually add the spacers so you don't need to make adjustments by setting the pushFollowers flag in your pin to false.
Example JS
controller.pin($('#pin-id'), 200, {
anim: new TimelineLite().append([TweenMax.fromTo( $('#pin-id'), 2, {css:{opacity: 1}}, {css:{opacity: 0}})]),
offset: 0,
pushFollowers: false
});
Example HTML
<div id="pin-id">
Bunch of Content
</div>
<div style="padding-top: 200px"></div>

I'm trying to make some buttons work here.
http://www.sepulturaimpex.ro/portofoliu is the website.
When i click left/right buttons i'd like to move from project to project exactly
The images are random width.
How can i achieve that?
Here is the script i'm using.
$(document).ready(function () {
$(".prev").click(function () {
$(".p_horizontal_wrap").animate({
scrollLeft: "-=700"
})
}), $(".next").click(function () {
$(".p_horizontal_wrap").animate({
scrollLeft: "+=700"
})
})
}),
The answer is in your question; if the images are random width, then you cannot scroll w/ a fixed width
I think your best bet is to look ahead and find the x position of the next object, then scroll to that. Depending on your markup, you may need to keep track of the object index you're scrolling into view.
Your next button (and your next/prev could be the same) would look like this:
$(".next").click(function() {
var targ = /** find out the next item to be shown **/
var left = $(targ).position().left;
$(".p_horizontal_wrap").animate({
scrollLeft: left
});
});
I have a form that is sticky on every page, and I need it to stop being sticky when it reaches the top of the footer. I have this working properly, but I need it to become sticky again when scrolling back up the page. Anything glaringly wrong?
$(window).scroll(function(){
var footerTopPos = $('#footer-wrapper').offset().top;
var navBottomPos = $('#footer-form-wrapper').offset().top;
if(navBottomPos >= footerTopPos) {
$('#footer-form-wrapper').addClass('sticky');
} else {
$('#footer-form-wrapper').removeClass('sticky');
}
});
To clarify, the first part works perfectly. The css changes from "fixed" to "absolute" and the form stays in place. The problem is, I want it to revert back to "fixed" when you start scrolling back up the page (my else statement). This part does nothing at all.
Here is a rough jsfiddle to show the issue http://jsfiddle.net/L693f5bg/14/
--Edit--
To keep what you have started with the same and not use any other plugins you have to make sure you are declaring the variable outside the scroll function so that it doesn't get changed every time you scroll and change its position.
$(function () {
var footerTopPos = $('#footer-form-wrapper').offset().top;
$(window).scroll(function () {
var windowTopPos = $(window).scrollTop();
if (windowTopPos >= footerTopPos) {
$('#footer-form-wrapper').css('position', 'absolute');
$('#footer-form-wrapper').css('top', '0');
} else {
$('#footer-form-wrapper').css('position', 'fixed');
$('#footer-form-wrapper').css('bottom', '0');
$('#footer-form-wrapper').css('top', 'auto');
}
});
});
Updated your JSFiddle
Personally I recommend using Waypoints.js and the sticky elements plugin. It does everything and it's super clean and easy to implement. include the jquery.waypoints.js and the sticky plugin then initialize using:
var sticky = new Waypoint.Sticky({
element: $('#footer-wrapper')[0],
offset: '90%',
stuckClass: 'unstuck'
});
I updated the JSFiddle using the Waypoints.js plugin
I have a simple blog, and each blog post has a number of images ranging from 1 to 10. If you click on any of the images in the post, it should scroll you down to the next post. I thought something as simple as this would've worked:
$('.each-journal-entry .slider-container .journal-slider .each-slide img').on('click', function () {
var $this = $(this);
$('.journal-container').animate({
scrollTop: $this.closest('.each-journal-entry').next().offset().top
}, 500);
});
But when I click another image, except for the first one, it just scrolls to an odd position.
I managed to achieve this with some help, and you can see the output here: http://jsfiddle.net/w7rtcmp0/3/ which works great, but the difference for me is that my content is in a scrollable div (hence .journal-container and not html, body.
Any ideas why I am having this issue? I have created a jsFiddle with the scrollable div, and if you click an image further down... it replicates this issue... so hopefully this helps.
http://jsfiddle.net/w7rtcmp0/5/
Thanks.
jQuery adjusts offset().top() based on the current scroll position.
Using JavaScript's offsetTop property should fix the problem:
scrollTop: $this.closest('.each-journal-entry').next()[0].offsetTop
Fiddle: http://jsfiddle.net/m7cm5oL6/
So I think you were trying to use the wrong height.
Here I set a variable of height and set it to the height of the current journal/blog object. This allows me to scroll my height all the way down to the next available blog object.
http://jsfiddle.net/w7rtcmp0/24/
$('.each-journal-entry .slider-container .journal-slider .each-slide img').on('click', function() {
$this = $(this);
var height = $this.closest('.each-journal-entry').height();
$('.scrollable').animate({
scrollTop: height
}, 2000);
});
You may want to look at Ariel Flesler's jQuery scrollTo plugin, I had the same issue and using this saved me hours of debugging.
Here is the fiddle I'm working with: http://jsfiddle.net/fz5Yk/5/
As you can see, it has a one-page scrolling navigation. I want to achieve a highlighting effect (preferably using .animate function) to the headings in <strong> </strong> tags when scrolling to a section. Just scroll the page manually and you will see a highlighting in the navigation menu; item of the scrolled section, but I can't quite resolve the js codes in order to apply the same to the headings, and an intervention in it with .animate function seems much more difficult to me. Can you help me?
The plugin-page seems well-documented; https://github.com/davist11/jQuery-One-Page-Nav.
Just put an animation on the location you scroll to inside the end: definition;
$('#nav').onePageNav({
end: function() {
//I get fired when the animation is ending
}
});
Test update
$(window).scroll(function() {
var visible_start = window.pageYOffset;
var window_height = window.innerHeight;
var section3_height = $('#section-3').height();
var section3_start = $('#section-3')[0].offsetTop;
if ((visible_start - window_height >= section3_start) &&
$('#section-3').css('background-color', 'yellow');
}
});
I have the following code below that changes a div's position to fixed once an element scrollTop is greater than a number. I am trying to either amend this script or find a different solution so that the div will scroll between a range and STOP scrolling at some point ( so the div doesn't go off the page or overlap with footer elements.
I don't know if the right way is to say that IF scrollTop is greater than 150 then position=fixed, and if it's greater than 600 then position goes back to absolute, or if there's a better way, like distance from the bottom...
AND I use MooTools, not jQuery. I know there are a few jQuery options / plugins that do this. Thanks in advance!
window.onscroll = function()
{
if( window.XMLHttpRequest ) { // IE 6 doesnt implement position fixed nicely...
if (document.documentElement.scrollTop > 150) {
$('tabber').style.position = 'fixed';
$('tabber').style.top = '0';
} else {
$('tabber').style.position = 'absolute';
$('tabber').style.top = 'auto';
}
}
}
the script above is wrong on many levels.
don't use window.onscroll but window.addEvent("scroll", function() {});
cache selectors. using $("tabber") 3 times on each scroll when the element does not change is expensive.
just do var tabber = $("tabber") and reference that.
you don't need to do
$("tabber").style.position = ...
$("tabber").style.top = ...
do:
tabber.setStyles({
position: "fixed",
top: 12123,
right: 24
});
There are mootools plugins for this, eg scrollSpy by David Walsh: http://davidwalsh.name/mootools-scrollspy
it can allow you to set scripted events upon reaching various scrolling destinations or events, look at the examples.
or you could just write it yourself, eg, this took me 15 mins to do:
http://jsfiddle.net/dimitar/u9J2X/ (watch http://jsfiddle.net/dimitar/u9J2X/show/) - it stops being fixed when it reaches to 20 px of the footer. and then goes back to fixed if scrolling up again.
