The menu is currently set up so that when you open a page it is visible at the bottom of the page. As you scroll up the black menu panel will disappear out of view then reappear with the logo from the top.
Is there a way to reverse it so that once you scroll back up the black menu will disappear and reappear at the bottom of the page?
see website by clicking here
var distance = $('#content-div').offset().top,
$window = $(window);
var didscroll=true;
$window.scroll(function() {
if(didscroll==true){
if ( $window.scrollTop() >= distance ) {
didscroll = false;
//alert("r");
// Your div has reached the top
jQuery('.header').css({"position":"fixed","top":'-100px',"left":0});
jQuery('a.logo').css("visibility","visible");
jQuery( ".header" ).slideDown( 5000, function() {
jQuery(this).css({"top":0});
});
}
}
});
});
Remove the inline styles when you reached the breakpoint. Like this
if ( $window.scrollTop() >= distance ) {
$(".header").attr({style : ""});
$("a.logo").attr({style : ""});
}
Try this one..
var oritop = -100;
$(window).scroll(function() { //on scroll,
var scrollt = window.scrollY; //get the amount of scrolling
var elm = $(".box"); //get the box we want to make sticky
if(oritop < 0) {
oritop= elm.offset().top; //cache the original top offset
}
if(scrollt >= oritop) { //if you scrolled past it,
//make it sticky or else
}
else { //otherwise
//Do what you want to
}
});

I have a navbar that hides when I scroll down and shows up when I scroll up. That works fine.
But on smaller screens I have a full width menu that expands with a hamburger toggle and when I scroll even then hides. Is there a solution to fix that?
I also wonder if the navbar always could be visible when it's on top of the page.
Thanks on behalf.
My website
// detect scroll top or down
if ($('.smart-scroll').length > 0) { // check if element exists
var last_scroll_top = 0;
$(window).on('scroll', function() {
scroll_top = $(this).scrollTop();
if(scroll_top < last_scroll_top) {
$('.smart-scroll').removeClass('scrolled-down').addClass('scrolled-up');
}
else {
$('.smart-scroll').removeClass('scrolled-up').addClass('scrolled-down');
}
last_scroll_top = scroll_top;
});
}
Found the solution:
// detect scroll top or down
if ($('.smart-scroll').length > 0) { // check if element exists
var last_scroll_top = 0;
$(window).on('scroll', function() {
scroll_top = $(this).scrollTop();
if(scroll_top > last_scroll_top && last_scroll_top > 40) {
$('.smart-scroll').removeClass('scrolled-up').addClass('scrolled-down');
}
else {
$('.smart-scroll').removeClass('scrolled-down').addClass('scrolled-up');
}
last_scroll_top = scroll_top;
});
}
$(document).ready(function(){
$(".navbar").on('shown.bs.collapse', function(){
$('.smart-scroll').removeClass('scrolled-down').addClass('scrolled-no');
});
$(".navbar").on('hidden.bs.collapse', function(){
$('.smart-scroll').removeClass('scrolled-no').addClass('scrolled-down');
});
});
I'm currently making an overlay that covers a sticky top bar when the user has scrolled beyond a certain point (down) and disappears when scrolling back up. However, I'd like to be able to scroll for at least 50px before the code is executed (something like a gap before the overlay is triggered).
$(function() {
var prevScroll = $(document).scrollTop(); //initial position
$(window).scroll(function() {
var newScroll = $(document).scrollTop(); //position from top after scrolling
if(newScroll > prevScroll) { // checks if the user has scrolled up or down
var fromNew = $(document).scrollTop(); // holds value to compare with the position + gap amount
if (fromNew > newScroll + 50) { //checks to see if scrolled for 50px
$("#stick-start").fadeIn("fast");
prevScroll = newScroll + 50; //initial position + scrolled amount
};
} else {
var fromNew = $(document).scrollTop();
if (fromNew > newScroll - 50) {
if ($("#stick-start").hasClass("is-stuck")) {
$("#stick-start").fadeOut("fast");
prevScroll = newScroll - 50;
};
};
};
});
});
The condition that checks whether you're scrolling up or down works. But as it is now, the overlay just keeps fading in and out repeatedly. How do I make it so that you have to scroll at least 50px before anything happens ?
I think this should get you where you're going.
var $document = $(document);
$(window).scroll(function() {
if ($document.scrollTop() >= 50) {
$("#stick-start").fadeIn("fast");
} else {
$("#stick-start").fadeOut("fast");
}
});
EDIT: had an error, should be good now.
$(window).scroll(function() {
if ($(this).scrollTop() >= 50) {
$("#stick-start").fadeIn();
} else {
$("#stick-start").fadeOut();
}
});
I have two menus on a page, I am trying to show the one when the page is loaded and the other when there is a scroll.
This is my page Link
I would like to show the white part when position is at the top
and the blue part when there is a scroll past the top position
This is what am trying presently
<script type="text/javascript" src="//code.jquery.com/jquery-git.js"></script>
<script type='text/javascript'>//<![CDATA[
$(function(){
// Hide Header on on scroll down
var didScroll;
var lastScrollTop = 0;
var delta = 5;
var navbarHeight = $('header').outerHeight();
$(window).scroll(function(event){
didScroll = true;
});
setInterval(function() {
if (didScroll) {
hasScrolled();
didScroll = false;
}
}, 250);
function hasScrolled() {
var st = $(this).scrollTop();
// Make sure they scroll more than delta
if(Math.abs(lastScrollTop - st) <= delta)
return;
// If they scrolled down and are past the navbar, add class .nav-up.
// This is necessary so you never see what is "behind" the navbar.
if (st > lastScrollTop && st > navbarHeight){
// Scroll Down
$('header').removeClass('nav-bar-below op-page-header cf').addClass('banner include-nav');
} else {
// Scroll Up
if(st + $(window).height() < $(document).height()) {
$('header').removeClass('banner include-nav').addClass('nav-bar-below op-page-header cf');
}
}
lastScrollTop = st;
}
});//]]>
</script>
can some one please help its not working for me
You can just detect if the scroll is at the top of the page or not whenever scroll event fired. if yes, show white header, and vice versa
$(window).scroll( function() {
var scrollPosition = $(window).scrollTop();
if(scrollPosition === 0) {
//show white header
}
else {
//show blue header
}
}
Of course you have to make sure when page first load, it show the white one first (use css). since the code above won't run Until user do scroll (fire this event)
*EDIT
for this :
"and the blue part when there is a scroll past the top position"
you can try this plugin
http://stickyjs.com/
sample code for fix the menu at top position.
$(document).scroll(function() {
var y = $(document).scrollTop()
var header = $('.include-nav');
var blue-menu = $('.cf');
var screenHeight = header.height();
if (y >= screenHeight) {
blue-menu.css({
position : "fixed",
"top" : "0",
"left" : "0"
});
header.css("position", "relative");
} else {
blue-menu.css("position", "relative");
}
});
I have a series of divs that are 100% height with a scroll to function that takes you to the next div out of the viewport on background click. However, if the next div is already slightly in the viewport the whole thing is counted as being visible and the scroll to bypasses it. Can anyone offer direction on how to get the script to scroll to the div even if it's partially in the viewport already?
Codepen here.
If you begin scrolling slightly in the codepen and then click on the background you'll see that it doesnt scroll you to the div that's already in the viewport but the div after that.
$(document).ready(function() {
// get initial nav height
var $window = $(window);
var wst = $window.scrollTop();
var th = $('div.top').height();
var currentSlide = $('#wrapper').data( 'current-slide', $('div.slide').eq(0) );
$('div.scroll_images').css({ height: 'auto', overflow: 'visible', top: 0 });
$('div.scroll_images div.inner').css({ position: 'absolute', top: 0 });
$('div.slide').each(function() {
$(this).css('padding',function() {
return (($(window).height()-$(this).height())/2)+'px 0'
});
});
// scrollto for click on slide
jQuery.fn.scrollTo = function(hash) {
$this = $(this);
st = $this.offset().top - th; // subtract nav height
$('html, body').animate({ scrollTop: st }, 550
);
}
$('#wrapper').click(function(e){
//get the current slide index from the body tag.
$this = currentSlide.data( 'current-slide' );
$next = $(".slide:below-the-fold");
if($next.length) {
$next.scrollTo($next.attr('id'));
//Save the next slide as the current.
$('#wrapper').data( 'current-slide', $next );
} else {
//Throw us back to the top.
$('div.slide:first').scrollTo($('div.slide:first').attr('id'));
//Save the first slide as the first slide, which
//Cycles us back to the top.
$('#wrapper').data( 'current-slide', $('div.slide:first'));
}
})
//Images fade in
$('img').hide();
$('img').each(function(i) {
if (this.complete) {
$(this).fadeIn();
} else {
$(this).load(function() {
$(this).fadeIn();
});
}
});
//Stop links affecting scroll function
$("a").click(function(e) {
e.stopPropagation();
});
});
(function($) {
$.belowthefold = function(element, settings) {
var fold = $(window).height() + $(window).scrollTop();
return fold <= $(element).offset().top - settings.threshold;
};
$.extend($.expr[':'], {
"below-the-fold": function(a, i, m) {
return $.belowthefold(a, {threshold : 0});
}
});
})(jQuery);
Here's what I might try to do: go through each div in the series. Find the div who's offset() is closest to $(window).scrollTop(). Now, find the next() div after the "current" one and scroll to it.
For comparing the offset() of each div, try something like this:
var closest = $('[selector]:first');
$('[selector]').each(function() {
var oldDistance = Math.abs(closest.offset() - $(window).scrollTop());
var newDistance = Math.abs($(this).offset() - $(window).scrollTop());
if(newDistance < oldDistance) {
closest = $(this);
}
}
I have aa div that I want to slide in once the user scrolls down a specified amount. It initially works but after than the div keeps moving to the left a little on every scroll action instead of staying in place. Anyone has an idea why is this happening?
var opening = false;
var closing = false;
$(window).scroll(function(){
var windowHeight = $(window).height();
var windowScroll = $(window).scrollTop();
var position1 = $("#Support").offset().top;
if ( windowScroll > (position1 - (windowHeight/2)) )
{
if (!opening) {
opening = true;
closing = false;
$("#SupportImage1").stop().animate({
left: "1200px"
}, 1500, function(){
opening = false;
});
}
}
else
{
if (!closing) {
closing = true;
opening = false;
$("#SupportImage1").stop().animate({
left: "100%"
}, 1400, function() {
closing = false;
});
}
}
});
the scroll bar is most likely affecting your width calculations.
everytime you run that function against the scroll bar you are adding in the total screen width plus the offset by the scroll bar.
