divs are showing underneath one bye one of DIV
is there any option to show each .slide on the basis of mouse scrolling ?
go to underneath while scroll up

You can check out the current scroll top, and then based on that, fire a jQuery code to activate the current tab. That's possible. A few things are unclear about your question. First being, this looks like a homework question. We would like to know what you have done so far. Secondly, you didn't provide what you need to do after the scroll.
$(document).ready(function(){
$(window).scroll(function(){
if (window.scrollY > 100)
$(".slide[data-slide='2']").height(2000);
});
});

I am trying to find a way to enable my pop up window expand in a similar fashion as the Facebook Birthday popup expands. If you login to your Facebook page and click the "others" link next to where it shows how many of your friends have birthdays today, you will notice the pop up window shows up very small and then grows in a vertical fashion.
How am I able to do this?
I created a fiddle to show what I have so far.
https://jsfiddle.net/05w8fpL5/
I have added..
.fadeIn("slow");
and
.fadeOut("slow");
So far which I like, but I wish I had some say so on how long it took to fadeIn and Out.
Does anyone know how I could accomplish this?
You can achieve this using the .slideUp() and .slideDown events in Jquery. This will provide the vertical expanding animation that you are looking for. So change your .fadeIn and fadeOut functions, an important note that the slide functions do not work with min-height, you will need to remove that CSS from .admin_help_popup for this to work:
$('.admin_popup').on('click',function(){
$(".light_admin,.white_overlay").slideDown("slow");
});
$('.close_admin_popup').on('click',function(){
$(".light_admin,.white_overlay").slideUp("slow");
});
If it's completely necessary you have that min-height property, you can set min-height back to it's default value after .slideDown. You can try and make it smoother by using .animate(). Make sure to set mine-height to 0px on the slide up:
$('.admin_popup').on('click',function(){
$(".light_admin,.white_overlay").slideDown("slow", function(){
$(".admin_help_popup").animate({"min-height": "380px"}, "fast");
});
});
$('.close_admin_popup').on('click',function(){
$(".admin_help_popup").css("min-height", "0px");
$(".light_admin,.white_overlay").slideUp("slow");
});

I am working on building a schedule. So far it's pretty straight-forward. There is one bit of functionality I am having issues with.
I have an ul that has a fixed height to allow scrolling. There are "Labels" (li.dayLabel) withing the ul that separate the hours. What I am trying to do is to have it so that when a label is scrolled out of view it will change the text in the placeholder to it's text. Then once that works, I need it to work in reverse. So when they label scrolls back into view it updates the placeholder. Basically, I am trying to make the placeholder be a title for the available items until another label is then scrolled out of view. This is for scrolling from the top. So as you scroll down the list the placeholder is meant to be a title for the section you are viewing until you reach another section and it takes its place. Then when you scroll back down I need it to replace the text with the previous li.dayLabel so the sections stay organized. I hope this makes sense.
You can see what I am trying to do by looking at the original that I am basing this off of. Notice how the placeholder changes as you scroll down the list and changes back when you scroll back up.
Demo: jsFiddle // Note: line 54 is the part that is in question
I originally used:
$(".snlf-schedule-list li.dayLabel:visible:first").text();
as the :first selector is suppose to only match a single element.
I later tried:
$(".snlf-schedule-list li.dayLabel:visible").filter(":eq(0)")
as this is suppose to be the same thing.
It seems that when an element is out of view it still is considered :visible I believe this is my issue.
Am I doing this completely wrong? I was under the impression that when you scroll an element like this it should no longer be :visible. After reading the documentation I have learned that this is not the correct selector to use.
It would appear that scrollTop is how I should be doing this. Now I have used scrollTop for scrolling down pages to disable animations when not in view but I am not clear on how to untilize this for a ul with scrollbars.
I tried:
var _first = $('li.dayLabel:first'); // next element to scroll out of view?
if( $(this).scrollTop() > (_first.offset().top+_first.height())) {
// Out of view
console.log("out");
} else {
// in view
console.log("in");
}
Updated Demo: jsFiddle
But it seems to be redundant as it's already calculating the first element so I am not sure how to get the correct element (the next one that's about to scroll out of view.) Then I need this to work when they scroll back up...
Any insight on this is much appreciated. Hopefully it's something simple I am just over complicating or missing completely.
Thanks,
Jeremy
The solution for my case was:
// Set placeholder text on scroll
var _scrollCagePositionTop = $(".snlf-schedule-list").offset().top;
var _first = $('li.dayLabel:first'); // first dayLabel element
$(".snlf-schedule-list").scroll(function(){
var _lastOffText = $(_first).text();
$("li.dayLabel").each(function() {
if ($(this).offset().top < _scrollCagePositionTop) {
_lastOffText = $(this).text();
}
});
$("#schedule-placeholder").text(_lastOffText);
});
What I did was set the known position of the top of the scroll cage (_scrollCagePositionTop)
When the user scrolls I set a variable _lastOffText that keeps track of the last item text content when scrolled out of view (less offset top than the palceholder). I then set this value to the placeholder.
This method allows me to have the proper text in my placeholder when the user scrolls up or down.
To fix the issue of an empty placeholder when the user scrolls back to the top I just set the default of _lastOffText to be the text of the first label ($(_first).text())
Hope others find this useful.
Here is the working demo: jsFiddle Final
I was wondering if anyone knows if there was a javascript or something that scrolls a site left right up and down on a click.
For example I want to create a site with multiple divs. Look at photo below.
I want each div to fit to screen and div 1 being the main div, the starting point. Say that I had a link in the menu for biography and the content for biography was in div 4 and someone click biography, I want the site to move down to div 3 and then right to div 4 and the same thing goes for div 4 and all the divs. When someone clicks a link in the divs I want the site to scroll in a direction I specify, is this possible.
Left Right Up Down
The jquery animate function is the right way.
Here you can find a simple and clear tutorial on how to use it: http://gazpo.com/2012/03/horizontal-content-scroll/
The tutorial is for horizontal scroll only, but you can easily extend to scroll your page in both directions (vertical and horizontal at the same time).
Yes, they are:
.scrollLeft()
.scrollRight()
With jQuery, you can animate the body's scrollTop value to scroll up and down:
$("html,body").animate({
scrollTop: $("#bio").offset().top
}, 1000);
The above code will scroll to the element with the id of #bio.
In terms of scrolling sideways, I supposed you could use a little trick. Set the body's overflow-x to hidden to hide anything that overflows to the right of the browser viewport. Then you can adjust the margin-left of body to "scroll" to the right or left. But, of course, this removes the ability for users to scroll through all of your divs.
$("body").animate({
marginLeft: "-100%"
}, 1000);
you can use jquery animate function ,it will give you more control
$('#div').animate({
left: '+=50'
}, 5000, function() {
// Animation complete.
});

I'd like to set up a "backward-compatible" scrolling sidebar on one of my pages.
I have a page containing information about a species of fish which can be extraordinarily long and images to accompany it.
The images are in the right-hand pane at the moment and I'd like them to follow the user as they scroll to the bottom of the page.
I've used the following code with some success:
jQuery().ready(function($) {
var $scrollingDiv = $("#sidebar");
$(window).scroll(function(){
$scrollingDiv
.stop()
.animate({"marginTop": ($(window).scrollTop() + 30) + "px"}, "slow" );
});
});
But it jumps too far when scrolling down.
(original position)
(scrolled a single mousewheel click)
When you start scrolling down the page, the sidebar appears around half-way down and as such you can only see two of the images.
Once a user scrolls past X point (say 400px), I would like the sidebar to start moving with the page. However, it also needs to go back to its original position when the user reaches the top of the page once more.
Is there a fix that can be applied to this code, or a better way of approaching this?
---------------------------------------------------------------------------------
EDIT: position:fixed Problem
When I try to apply position:fixed as per Josh and David's suggestions (either bit of JS code), this happens:
Here is Firebug's read-out of the CSS styles attached to this element:
You can use a plugin for this, but it’s such a simple task that you might as well do it on your own.
Consider this simple markup:
<div id="content">Content</div>
<div id="sidebar"><div>Sidebar</div></div>
And this would be all the javascript you need:
var el = $('#sidebar'),
pos = el.position().top;
$(window).scroll(function() {
el.toggleClass('fixed', $(this).scrollTop() >= pos);
});
Now, it will add a class to the #sidebar div as soon as the user scroll further than the sidebar is positioned, so all you need now is som CSS. I’m applying the fixed positioning to a child element to avoid layout problems:
#sidebar.fixed > div{position:fixed;}
I put up a really simple demo here: http://jsfiddle.net/QZyH3/
You should try the jQuery code found in this tutorial, which replicates Apple's shopping cart sidebar. It has a working demo and a very small code footprint.
why not use css position: fixed; property? of course if you don't mind the div being not smooth but straightly following your scrollTop. I've found it not working only in IE6-- by today, so using fixed position is a good solution I think, otherwise you just get with window.scrollTop of DOM and assign it to your element's absolute position top
I've been trying to get a DIV to move up when using the scroll on browser to move down, but I can't find a solution which works.
More specifically, for example if I fill a DIV with images, I want these images to scroll upwards when I scroll the browser window scrollbar downwards. So as you move longer down the page, the DIV moves upwards and shows more images.
Could you give me some suggestions how to receive such an effect?
Try something like this:
$(window).scroll(function(){
$("#scrollingDiv").stop().animate({ "marginTop": ($(window).scrollTop() + 30) + "px"}, "slow");
});
I don't entirely follow what you are trying to do with the <div> content, but there is an easy way to detect page scrolling with jQuery:
$.scroll(function() {
alert('Scroll position: ' + $('html').scrollTop());
});
From there, you can position whatever you want, however you want, using this value $('html').scrollTop().
Maybe I'm misunderstanding but, are you trying to keep your DIV in a fixed position regardless of how far the user scrolls down the page?
If so there's a style for that:
position:fixed
