I use this to position my div:
$(document).ready(function (){
$(window).resize(function (){
$('.classname').css({
position:'absolute',
left: ($(window).width() - $('.classname').outerWidth())/2,
});
});
$(window).resize();
});
but after scrolling down, i want to stick on the top, so withouth positioning I use this:
$(window).scroll(function(){
if($(document).scrollTop() > 150){
$('.class name').addClass('shrink');
}
else{
$('.class name').removeClass('shrink');
}
});
here is the css for shrink:
.shrink{
top: 0;
left: 0;
position: fixed;
width: 100%;
}
Can someone help me, how to merge the two scripts?
thanks
don't know if i understand you correctly, but you can try this:
CSS
.classname{
top: 0;
position: absolute;
}
.classname.shrink{
left: 0 !important;
position: fixed;
width: 100%;
}
JS
$(document).ready(function (){
$(window).resize(function (){
$('.classname').css({
left: ($(window).width() - $('.classname').outerWidth())/2,
});
});
$(window).scroll(function(){
if($(document).scrollTop() > 150){
$('.classname').addClass('shrink');
}
else{
$('.classname').removeClass('shrink');
}
});
$(window).resize();
});

Long story short: I'd like to scroll through full-screen divs. Looking at previous question I found this which is quite close to what I need but with some changes.
https://jsfiddle.net/naqk671s/
Instead of having the div #1 fixed and the #2 landing on the top of it, I'd like to have the #1 going up and revealing the #2.
My confidence with jQuery is not so big, so I tried to change some values but I just made it worst. do you think is possible to achieve the result with few changes or should I just start from scratch?
under = function(){
if ($window.scrollTop() < thisPos) {
$this.css({
position: 'absolute',
top: ""
});
setPosition = over;
}
};
over = function(){
if (!($window.scrollTop() < thisPos)){
$this.css({
position: 'fixed',
top: 0
});
setPosition = under;
}
};
To make my self more clear, what I'm trying to achieve is basically the opposite of the fiddle I've posted. If you scroll all the way down and than start to scroll up that will be the effect I'd like to achieve but upside down.
Thanks in advance

I have a problem with jQuery.
I want to add the fixed-top class (Bootstrap 4) when scrolling the page, but this is not the case.
jQuery(document).ready(function($){
var scroll = $(window).scrollTop();
if (scroll >= 500) {
$(".robig").addClass("fixed-top");
} else {
$(".robig").removeClass("fixed-top");
}
});
Can you see what I'm doing wrong?
Your scroll variable is never being updated. You need to add your code into a scroll event like so:
jQuery(document).ready(function($) {
$(window).scroll(function() {
var scroll = $(window).scrollTop();
if (scroll >= 130) {
$(".robig").addClass("fixed-top");
} else {
$(".robig").removeClass("fixed-top");
}
});
});
body {
margin: 0;
}
.foo {
height: 140vh;
background: black;
}
.robig {
width: 100%;
height: 10vh;
background: lime;
}
.fixed-top {
position: fixed;
top: 0;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="foo"></div>
<div class="robig"></div>
<div class="foo"></div>
However, if you are trying to recreate a sticking effect, I suggest you use position: sticky as jquery isn't needed for this:
body {
margin: 0;
}
.foo {
height: 140vh;
background: black;
}
.robig {
width: 100%;
height: 10vh;
background: lime;
position: sticky;
top: 0;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="foo"></div>
<div class="robig">Stop at top</div>
<div class="foo"></div>
Your code run on page load only but you need to run your code in scroll event of window
$(window).scroll(function(){
var scroll = $(window).scrollTop();
if (scroll >= 500)
$(".robig").addClass("fixed-top");
else
$(".robig").removeClass("fixed-top");
});
Also you can simplify the code and use .toggleClass() instead
$(window).scroll(function(){
$(".robig").toggleClass("fixed-top", $(window).scrollTop() >= 500);
});
$(window).scroll(function(){
$(".robig").toggleClass("fixed-top", $(window).scrollTop() >= 500);
});
p {height: 500px}
.robig {
width: 100%;
background: red;
}
.fixed-top {
position: fixed;
top: 0;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<p>content</p>
<div class="robig">robig</div>
<p>content</p>
<p>content</p>
$(document).ready(function(){
var scroll = 0;
$(document).scroll(function() {
scroll = $(this).scrollTop();
if(scroll > 500) {
$(".robig").addClass("fixed-top");
} else {
$(".robig").removeClass("fixed-top");
}
});
});
You need to window scroll event. You can try below code
$(document).ready(function(){
$(window).scroll(function(){
if ($(this).scrollTop() >= 130)
{
$(".robig").addClass("fixed-top");
}
else
{
$(".robig").removeClass("fixed-top");
}
});
});
I need a help with this auto-scrolling. Please help me to pause the scrolling when Hovering the Mouse over it. Thank you.

I have a function where I want to move the scroll down if it is at the top. But nothing happens, before and after the function value is still 0.
This is the code:
scrollDrawer = function () {
if (drawerIsUp) {
console.log($(window).scrollTop());
$(window).scroll(function() {
if ( $(window).scrollTop() < 92 ) {
$('html, body').animate({
scrollTop: $(".middle").offset().top
}, 2000);
}
});
console.log($(window).scrollTop());
function winScroll() {
drawerDiv.style.top = (drawerDiv.offset + window.pageYOffset) + "px";
}
}
}
Updated
console.log($(window).scrollTop());
$(window).scroll(function() {
if ( $("html,body").scrollTop() < 92 && $("html,body").scrollTop() > 0) {
$("html,body").scrollTop(800)
}
});
console.log($(window).scrollTop());
I have updated the code and modifed it by applying suggestions from the answers, but still the scroll doesn't get relocated. I wonder if that is maybe since when the page opens it is already at top 0, and I need to relocate it immediately without scrolling from the user in the first place.
Html:
<div id="app">
<div id="bg">
</div>
#section('topBar')
#include('customer.layouts.partials.top-bar')
#show
<div id="main-section">
#section('header')
#include('customer.layouts.partials.header')
#show
#section('carousel')
#include('customer.layouts.partials.carousel', ['function' => 'drawer', 'carouselPadding' => ''])
#show
</div>
<div id="drawer">
<div id="magazine-detail">
</div>
<div id="magazine-detail-carousel">
#section('magazine-detail-carousel')
#include('customer.layouts.partials.carousel', ['function' => 'magazineDetail', 'carouselPadding' => 'carouselPadding'])
#show
</div>
</div>
</div>
CSS:
#main-section {
height: calc(100vh - 92px);
overflow-y: scroll;
width: 100%;
position: fixed;
overflow-y: scroll;
top:77px;
}
#drawer {
z-index: 5;
position: fixed;
top: 100vh;
height: calc(100vh - 92px);
max-height: 100%;
overflow-y: scroll;
width: 100%;
background-color: $white;
padding-left: 15px;
padding-right: 15px;
}
.top-bar {
position: fixed;
top: 0;
}
On click div drawer that is first not visible since it is below the vh, goes over the top of the main-section all the way up to where the top-bar starts. This is the animation:
$('#drawer').animate({
top: 92
}, 500);
And then after that animation I want the scroll to start from the bottom so that I can when the user starts scrolling move the drawer back down again by the amount of pixels a user has scrolled up.
Try this
$(window).scroll(function() {
if ( $(window).scrollTop() < 92 ) {
// if want to animate scroll
$('html, body').animate({
scrollTop: $("body, html").offset(800)
}, 2000);
// otherwise
$("body, html").offset(800)
}
});
I think you make a mistake，you should addEventListener to window,and when the page init, window's scrollTop() eval 0,so your second example can't work.and the last,when the browser inited the page,all of console.log had excuted,so you would see two same result by console.log,you can try to move on into scroll function,so you can see the scrollTop of window when mouse scroll.
there are some example for you:
console.log($(window).scrollTop());
$(window).scroll(function() {
if ( $(window).scrollTop() < 92 && $(window).scrollTop() > -1) {
$(window).scrollTop(800);
}
console.log($(window).scrollTop());
});
the other one:
scrollDrawer = function () {
if (1) {
console.log($(window).scrollTop());
$(window).scroll(function() {
if ( $(window).scrollTop() < 92 ) {
$(window).scrollTop(800);
}
});
console.log($(window).scrollTop());
}
}
scrollDrawer();
This may not be exactly what you're looking for, but it is something that can work with a little css.
var wrap = $("#wrap");
wrap.on("scroll", function(e) {
if (this.scrollTop > 800) {
wrap.addClass("new");
} else {
wrap.removeClass("new");
}
});
I have a nav bar that is fixed to the top of the page when the width is under 768px.
When it is over 768px it starts at the bottom and when the user scroll past it it become stuck to the top.
Both of these instance work fine on their own, but when the browser is resized there are some issues when going from under 768px to above. (Going from 768 to below works fine.)
When I load the page in a browser size under 768px and then resize the window above that is where I run in to problems.
I would like for the nav bar to smoothly transition between states. (It works beautifuly when loading above 768px then reszing to under and reszing above - Ideally this is how I would like it to work when loaded below 768px.) Or as an alternative just have the nav bar be fixed to the top when moving from under 768px to above.
This is the link to the site.
This is my CSS
.header{
width: 100%;
min-width: 300px;
height: 100px;
padding: 0px;
background: black;
position: absolute;
bottom: 0px;
z-index: 99999;
-webkit-font-smoothing: subpixel-antialiased;
}
.header.fixed{
width: 100%;
position: fixed;
top: 0px;
height: 100px;
-webkit-font-smoothing: subpixel-antialiased;
}
#media only screen and (max-width: 768px){
.header{
width: 100%;
background: black;
position: fixed;
top: 0px;
height: 100px;
-webkit-font-smoothing: subpixel-antialiased;
}
}
and this is the Javascript
<script>
jQuery(document).ready(function() {
var s = jQuery(".header");
var pos = s.position();
jQuery(window).scroll(function() {
var windowpos = jQuery(window).scrollTop();
if (windowpos >= pos.top) {
s.addClass("fixed");
} else {
s.removeClass("fixed");
}
});
});
</script>
I have also tried below to no luck.
<script>
if ( jQuery(window).width() > 768) {
jQuery(document).ready(function() {
var s = jQuery(".header");
var pos = s.position();
jQuery(window).scroll(function() {
var windowpos = jQuery(window).scrollTop();
if (windowpos >= pos.top) {
s.addClass("fixed");
} else {
s.removeClass("fixed");
}
});
});
}</script>
<script>
jQuery(window).resize(function(){
if ( jQuery(window).width() > 768) {
jQuery(document).ready(function() {
var s = jQuery(".header");
var pos = s.position();
jQuery(window).scroll(function() {
var windowpos = jQuery(window).scrollTop();
if (windowpos >= pos.top) {
s.addClass("fixed");
} else {
s.removeClass("fixed");
}
});
});
}})</script>
try this:
function sticky_navigation() {
var browserWidth = $(window).width();
var scroll_top = $(window).scrollTop(); // our current vertical position from the top
// if we've scrolled more than the page, change its position to fixed to stick to top,
// otherwise change it back to relative
if ((scroll_top > $('.header').height()) && (browserWidth > 720)) {
$('.header').css({ 'position': 'fixed', 'top':0, 'z-index':999999, 'opacity': 0.9, 'box-shadow': '0px 3px 5px #393939' });
} else {
$('.header').css({ 'position': 'relative', 'opacity': 1, 'box-shadow': 'none' });
}
};
// and run it again every time you scroll
$(window).scroll(function() {
sticky_navigation();
});
// and run every time you resize to boot
$(window).resize(function() {
sticky_navigation();
});
