When the user scrolldown with the mousewheel, I'd like the page go down untill exactly the begining of the next element. Like :
<section class="One">
...
</section>
<section class="Two">
...
</section>
<section class="Three">
...
</section>
When you enter the website, you'll be at the start page, when you scrolldown 1x, I'd like the page scroll untill the begining of section 2 and so on...
Imagine the sections like, home / about / contact
I tried this, but in this example, I have to write the exactly name of the elements and I would have to write one of this for each section... Is there a different way to do so ?
window.onload=function myScroll() {
x = document.getElementById("chat");
h = x.clientHeight;
x.scrollTop = h;
}
<div id="chat" style="width: 100%; height: 70px; overflow: scroll;
border: 1px solid grey">
This can be quite complicated due to the fact that this involves scrolling, catching the mouse wheel events, delay in animations, cross browser usage, swipe and touch events. Fortunately, there are plugins available to make your life easier. One of the most popular ones is Full Page.
Some of the features include:
Usage over old browsers with no CSS3 support.
Add a live menu.
Slide throw the page using the keyboard arrows.
Add horizontal sliders.
Mobile and Tablet detection enabling the scrolling on them.
Usage:
Each section will be defined with a div containing the section class.
<div class="section">
<div class="slide"> Slide 1 </div>
<div class="slide"> Slide 2 </div>
<div class="slide"> Slide 3 </div>
<div class="slide"> Slide 4 </div>
</div>
All you need to do is call the plugin inside a $(document).ready function:
jQuery:
$(document).ready(function() {
$('#fullpage').fullpage();
});

I have a window scroll function that I am trying to dial in. Initially, I attempted to do with with waypoints, but couldn't figure it out.
My issue is my function is firing too early and not in the location I am wanting it to. It fires when the bottom of the screen gets to the main container this is all in, #home-info. The issue I have with this is if someone is scrolling slow they never see the animation. Ideally I want the function to fire when it gets to #info-container, the container with the animated objects in it.
What am I doing wrong that is not allowing this to happen or is there a better way to do this?
Fiddle. See it here
function boxes() {
window.addEventListener("scroll", function(event) {
var top, green, yellow, red;
top = this.scrollY;
green = document.querySelector("#green"),
yellow = document.querySelector("#yellow"),
red = document.querySelector("#red");
if(top > 100){
green.classList.add("green", "active");
yellow.classList.add("yellow", "active");
red.classList.add("red", "active");
}
}, false);
}
setTimeout(boxes,1200);

You don't want to hardcode your scrollbar position. The position at which your object becomes visible depends on the height of the view port, but more importantly on how much content you have above the target element.
Define a variable target with something like the following:
var target = $('#info-container').offset().top;
if(top >= target) {
// start animation
}
Also note that scroll top tells you nothing of what is in your view port, if you don't also look at the height of your window. In the condition above, use something like
var top = this.scrollY + $(window).height();
This will give you a condition that evaluates to true as soon as #info-container is scrolled into view. Depending on your needs, you may want your target to also include the $('#info-container').height(), if you want the scroll to start once the entire #info-container is in view.
My website consists of a navigation bar (class .nav-primary), a widget box (id #mw-panel) and an article. Recently, I tried to move the widget box up to the top, by applying the following changes to my CSS file:
.mw-panel{top: 50px;}
The problem with this option was, that my element was fixed to a specific position. Instead I wanted the widget element to be exactly 100px under the menu bar (and moving when I am scrolling down the page). Instantly, I knew that JavaScript would be the correct way to solve this problem.
Because I had no success, I asked the StackOverflow community, which helped me a lot.
The JavaScript code in the JS section of the attached code snippet, was partially done by me, but it does not work as it should.
Can someone explain me what I need to change to get this JS code working? Again, #mw-panel has to be positioned exactly 100px beneath .nav-primary.
var menu = document.getElementsByClassName("nav-primary")[0];
var widget = document.getElementById("mw-panel");
var difference = widget.offsetTop - menu.offsetBottom;
if (difference > 100) {
document.getElementById("mw-panel").style.top = (menu.offsetBottom + 100) + "px";
}
.content .entry {
margin-top: 40px;
padding-bottom: 400px;
}

There's No such property as offsetBottom. Redo your code ONLY considering offsetTop + offsetHeight to get bottom number.
Example:
var menu = document.getElementsByClassName("nav-primary")
var TrueOffset=menu[0].offsetTop+menu[0].offsetHeight;
You're getting the error because there is no offsetBottom property.
Do console.log(menu) in chrome to see the objects available properties
**Update:
Add this to your css:
.mw-panel{
position: absolute;
}
Here it is in action
Updated code in action
After re-reading your question, I missed one key detail: you're trying to do this JavaScript. This is your problem.
If I understand correctly, you have three items: a nav, an article, and a widget box. You want the widget box to stand 100px below the nav, and then move with the page when you scroll.
if this is the case (if not, correct me), then there's only a few things you need to do:
Keep your nav the way it is. Good job here.
I'm assuming you want the widget next to the article (on the left?). So you'll need to make two columns (some sort of containers, each height: 100%). Your widget container will have the property position: fixed; and the article will have position: static; (or relative, you decide).
Each container will have a width, you might choose 30% for the widget container and 70% for the article, for example.
Now you have two columns, one will move with the page as you scroll.
Here are some links to get you started:

I have this JS code:
function overlay() {
el = document.getElementById("overlay");
el.style.visibility = (el.style.visibility == "visible") ? "hidden" : "visible";
}
which opens up a new window on click. What I want it to do next from that first click is go to another function. That function entails a scroller that has 5 divs in it. Say I want it to go to the third div or ID, how would I go about writing that type of function? So a HTML example would be:
<div id="this">
<div class="outer">
<div class="innerdiv">
<div class="1" id="1">1</div>
<div class="2" id="2">2</div>
<div class="3" id="3">3</div>
<div class="4" id="4">4</div>
<div class="5" id="5">5</div>
</div>
</div>
</div>
This would represent my scroller. So on that initial first click, the idea is that it would open up a new window and scroll to that 3rd div, or if scrolling to it is to difficult, then go to that first div. http://jsfiddle.net/qYTK4/
<div class="arrowbox">
<div style="display:inline-block; width:155px; height: 50px; float:left;"></div>
<div class="leftbox" id="leftbox"></div>
<div class="backtohome">BACK TO HOME PAGE</div>
<div class="rightbox" id="rightbox"></div>
Using window.scrollTo() and move it to the objects position. Retrieve the position (X,Y) of an HTML element
jQuery.ScrollTo is a great, simple plugin for smooth scrolling animations. It has tons of options for ways to define the scroll behavior and is pretty easy to use. There are a ton of demos and examples on the site linked you should be able to use. In yours you would just tell it to scroll to either the DOM element itself or jQuery object/selector for the 3rd div.
Also, you can't have id attributes start with numbers (like your divs), it's not valid. Classes can but not IDs.
It is also a good idea to rely on click event handlers (i.e. $('.backtohome a').on('click', function() { // your code });) rather than onclick attributes.
I need to achieve an effect where when a user triggers a hover on an a tag, current content on the screen slides out, and the new content slides in (depending on what was hovered on). Here is my HTML:
<div class="services-image" style="background:url('/sites/default/files/services-background.jpg') top left no-repeat">
<ul>
<li>Secure Mobile Computing</li>
<li>IT<br />Consulting</li>
<li>Software<br />Engineering</li>
<li>Microsoft<br />Services</li>
<li>Cyber<br />Security</li>
<li>Infrastructure & System<br />Adminstration</li>
</ul>
</div>
</div>
So, when a user triggers a#box-2 hover, the divs below ease in/out with new content. Example container markup:
<div class="content-slides">
<div class="slide-1">text</div>
<div class="slide-2">text</div>
<div class="slide-3">text</div>
<div class="slide-4">text</div>
<div class="slide-5">text</div>
<div class="slide-6">text</div>
</div>

It should be easy enough to change the click events to mouseover.
I'm using Jqtouch to design a iphone app.
As I'm using a standard header/toolbar at the top, I want to simply have it fixed there without moving. I found out how to do this by creating a div with class toolbar and setting CSS display to block and min-height to 0px with important.
However, when it starts up and every time I change pages (technically, it's making different divs display and not display(?)), it autoscrolls to the top of the div that it just changed to, and I need to scroll up to see the toolbar (the toolbar is at the very top, above the div).
How do I make it actually scroll up to the toolbar or top of the page?
Here's a simplified layout of my current code: (For body section)
<body>
<div id="toolbar" class="toolbar" style="display: block; min-height: 0px !important;">
<h1>Header</h1>
<a class="button" href="#">Button</a>
</div>
<div id="home" class="current">
<!--Content in here-->
Link to next page
</div>
<div id="next">
<!--Content in here-->
</div>
</body>
I am not entirely sure I got your question, but It sounds like you want to have an element with "fixed" position. If that's the case, you may want to try the solution I posted for this question.
