On scroll take to specific location with jquery or javascript? - javascript

I'm not too sure how to describe this with words; but what I am planning to do is something like what this website has achieved: http://sapia.com.pe/
When you scroll down, it takes you to a specific point of the page, as well as when you scroll up. How could I do this using Jquery? Would any plugins be needed?

Check the SNIPPET below it will give you basic idea how it can be achieved
or you can use plugins like fullpage
var arr = ['_a','_b','_c'];
var i=0;
var doing=false;
$(window).bind('mousewheel', function(e){
if(e.originalEvent.wheelDelta > 0) {
if(i==-1) i=2;
if(!doing){
$('html, body').animate({
scrollTop: $("#"+arr[i--]).offset().top
}, 600,function(){doing=false;});
doing=true;
}
}
else{
if(i==3) i=0;
if(!doing){
$('html, body').animate({
scrollTop: $("#"+arr[i++]).offset().top
}, 600,function(){doing=false;});
doing=true;
}
}
});
body{
overflow: hidden;
}
.section,html,body{
width:100%;
height:100%;
}
.a{ background-color:red; }
.b{ background-color:yellow; }
.c{ background-color:blue; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="_a" class="section a"></div>
<div id="_b" class="section b"></div>
<div id="_c" class="section c"></div>

Overriding JavaScript smooth scroll

I have this code that works fine to smoothly scroll to an anchor point on a page.
$('a[href^="#"]').click(function () {
$('html, body').animate({
scrollTop: $('[name="' + $.attr(this, 'href').substr(1) + '"]').offset().top
}, 800);
return false;
});
That works whenever I want to the smooth scrolling functionality. The problem I have is that I want to link to an anchor point without a smooth scroll for one particular link. How could I do that?
Add a property for the links that you want to have smooth scroll and make the condition below.
You can also make the inverse and add a property for the link that you don't want to have smooth scroll.
$('a[href^="#"]').click(function () {
if($.attr(this, 'behaviour') === "smooth") {
$('html, body').animate({
scrollTop: $('[name="' + $.attr(this, 'href').substr(1) + '"]').offset().top
}, 800);
} else {
$('html, body').scrollTop($('[name="' + $.attr(this, 'href').substr(1) + '"]').offset().top);
}
return false;
});
.section1 {
height: 700px;
background-color: pink;
}
.section2 {
height: 600px;
background-color: yellow;
}

<body>
<h1>Smooth Scroll</h1>
<div class="main section1" name="section1">
<h2>Section 1</h2>
<p>Click on the link to see the "smooth" scrolling effect.</p>
<a behaviour="smooth" href="#section2">Click Me to Smooth Scroll to Section 2 Below</a>

<div class="main section2" name="section2">

the solution would be to use both html and body in JQ -> $('html,body').animate
see below ( i removed the scrollspy code as it's not relevant to this question, but you should keep it )
$(document).ready(function() {
// Add scrollspy to <body>
// Add smooth scrolling on all links inside the navbar
$("a").on('click', function(event) {
// Make sure this.hash has a value before overriding default behavior
if (this.hash !== "") {
// Prevent default anchor click behavior
event.preventDefault();
// Store hash
var hash = this.hash;
// Using jQuery's animate() method to add smooth page scroll
// The optional number (800) specifies the number of milliseconds it takes to scroll to the specified area
$('html,body').animate({
scrollTop: $(hash).offset().top
}, 1200, function() {
// Add hash (#) to URL when done scrolling (default click behavior)
window.location.hash = hash;
});
} // End if
});
});

Loading the right url with anchors and jquery on one page

I'm having an issue when i'm loading the pages on my website. The main page has anchors since it's a one page, however i wanted to add a blog so i made it a two pages website. The url looks like mywebsite.com#content But now when I'm on the blog and I'm trying to get back to the main page, but the url loads like that : mywebsite.com/blog#content.
So i'd like the url to look like that : mywebsite.com/#content, but i don't know if that's possible...
Here is the html for the links :
<li>Accueil</li>
<li>Projets</li>
<li>A propos</li>
<li>Contact</li>
<li>Blog</li>
To make a smooth scroll effect on the main I used the following jquery :
var scroll = {
scrollTo : function () {
var page = $(this).attr('href'); // Target page
var speed = 750; // Animation duration
$('html, body').animate( { scrollTop: $(page).offset().top }, speed ); // Go
return false;
} // attribute scrollTo
}; // object scroll
$('.js-scrollTo').on('click', scroll.scrollTo);
Is there a way to make the url this way : mywebsite.com/#content and still have the scrolling effect with jquery ?
Simple use e.preventDefault instead of return false. Also, add a control to check if your "anchor page" exists in the dom.
Example with external page: https://www.vixed.it/st/43002103
Anyway I think is better to change the name of your function, can create a misunderstand with jQuery scroll and scrollTo.
Don't forget that li tags should contains the a and and not the opposite.
var scroll = {
scrollTo : function (e) {
var page = $(this).attr('href');
if ($('div.page'+page).length) {
e.preventDefault();
var page = $(this).attr('href');
var speed = 750;
$('html, body').animate({scrollTop: $(page).offset().top}, speed);
} else {
location.href='/'+page; //your home url + #page
}
}
};
$('.js-scrollTo').on('click', scroll.scrollTo);
a{color:#09C}
.nav{
list-style:none;
position:fixed;
top:0;
right:0;
width:100%;
background:#000;

padding:5px 0;
}
.nav li{

}
.page{

}

auto scroll horizontal link jump

I want my link to animate scroll horizontally across the page to the desired "id" rather then jumping to it. this is what I have so far but it doesn't seem to be working.
HTML:
<div class = option1>
<a href= #point1> ➟ </a>
</div>
<div id = point1></div>
<!-- id point is not in the "body" of the link? does that matter? -->
CSS:
body {
min-height:100%;
height:100%;
margin:0;
width:auto;
}
html {
min-height:100%;
height:100%;
overflow-y:hidden;
width:100% }
JavaScript:
$(document).ready({
$(function() {
$('ul.nav a').bind('click',function(event){
var $anchor = $(this);
$('html, body').stop().animate({
scrollLeft: $($anchor.attr('href')).offset().left
}, 15000);
event.preventDefault();
});
});
});
Please try use class="name" not class=name
over wise this looks similar:

Having trouble getting the scroll animation to not trigger the scroll event

I currently have a number of div tags that can be seen below that are each the height of the viewport.
<!-- .current represents the div the user is currently viewing -->
<div class="full-height current" id="id1">
<div class="container">
</div>
</div>
<div class="full-height" id="id2">
<div class="container">
</div>
</div>
<div class="full-height" id="id3">
<div class="container">
</div>
</div>
<div class="full-height" id="id4">
<div class="container">
</div>
</div>
<div class="full-height" id="id5">
<div class="container">
</div>
</div>
I am attempting to implement a feature where upon a user scrolling, the window will scroll to the next div tag, always having only one div in view at a time. The way I implemented it works great, except for the fact that the animation triggers the scroll event again, resulting in an endless loop of the page scrolling once the user scrolls at all. I attempted to fix this by having a variable that will stop the event from triggering if the animation is in progress, but it does not seem to work. I am aware that I didn't do it for the scroll up, but I just wanted to see if it worked for the down first.
$(window).scroll(function(event) {
var scrollTop = $(this).scrollTop();
// If user scrolls down
if ((scrollTop > lastScrollTop) && $(".current").next("div").length > 0) {
if (animating == false) {
console.log("down");
$(".current").next("div").addClass("current");
$(".current").first().removeClass("current");
animating = true;
$("html, body").animate({
scrollTop: $(".current").offset().top
}, 1000, function() {animating = false});
}
// If user scrolls up
} else {
if ($(".current").prev("div").length > 0) {
console.log("up");
$(".current").prev("div").addClass("current");
$(".current").last().removeClass("current");
$("html, body").animate({
scrollTop: $(".current").offset().top
}, 1000);
}
}
lastScrollTop = scrollTop;
});
CSS included just in case. The 100vh - 111px is due to a fixed navbar at the top that is 111px high
/* Makes the element take up the entire height of the screen */
.full-height{
height: -o-calc(100vh - 111px); /* opera */
height: -webkit-calc(100vh - 111px); /* google, safari */
height: -moz-calc(100vh - 111px); /* firefox */
}
#id1 {
background-color: red;
}
#id2 {
background-color: blue;
}
#id3 {
background-color: yellow;
}
#id4 {
background-color: green;
}
#id5 {
background-color: purple;
}
If anyone could give me any ideas for fixing my problem, that would be great.
You'll want to stop the event and preventDefault. Here is some code from a current landing page:
$(document).ready(function () {
$('a.page-scroll').on('click', function(event) {
var link = $(this);
$('html, body').stop().animate({
scrollTop: $(link.attr('href')).offset().top - 50
}, 500);
event.preventDefault();
});
$('body').scrollspy({
target: '.navbar-fixed-top',
offset: 80
});
});
It uses bootstrap scrollspy so just ignore that. But notice that it stops any scroll animation that could be running and then also calls event.preventDefault() to stop the scroll event from bubbling and thus becoming recursive.
EDIT:
O.k. so I've a better look and the basic problem re: infinite scrolling is the code doesn't check if the scrollTop is already at 'where it needs to be'. You need an additional check to short circuit the scroll:
if (animating == false) {
if ($(this).scrollTop() == lastScrollTop) return;
if (($(this).scrollTop() > lastScrollTop) && $(".current").next("div")) {
console.log("down");
$(".current").next("div").addClass("current");
$(".current").first().removeClass("current");
animating = true;
$("html, body").stop().animate({
scrollTop: $(".current").offset().top
}, 1000,
function () { lastScrollTop = $(this).scrollTop(); animating = false; });
// If user scrolls up
} else {
if ($(".current").prev("div").length > 0) {
console.log("up");
$(".current").prev("div").addClass("current");
$(".current").last().removeClass("current");
$("html, body").stop().animate({
scrollTop: $(".current").offset().top
}, 1000, function () { lastScrollTop = $(this).scrollTop(); animating = false; });
}
}
}
Otherwise as it stands it will always either scroll up or down and never settle. That said with that "working" it's a terrible user experience. It will jump about since your scroll to code will fight the user on current scrollTop if they keep scrolling. i.e. your code will make it jump back to a previous position.
Try defining scroll event handler as named function ; defining lastScrollTop outside of scroll handler ; substituting .one() for .on() to allow animation to complete before re-attaching scroll event ; use .promise() which should be called at most once to avoid .animate() complete callback being called twice with selector "html, body" ; substituting single if to check for next or previous element .length and .animate() call for multiple if..else conditions and statements, animation function calls ; re-attach scroll event at .then() following animation completion .promise()
var lastScrollTop = 0;
function scroller(event) {
var scrollTop = $(this).scrollTop();
var direction = scrollTop > lastScrollTop ? "next" : "prev";
var el = $(".current")[direction](".full-height");
console.log(direction === "next" ? "down" : "up");
if (el.is("*")) {
$("html, body").animate({
scrollTop: el.offset().top
}, 1000).promise().then(function() {
console.log(this)
lastScrollTop = $(window).scrollTop();
$(".current")
.removeClass("current")[direction]("div")
.addClass("current")
setTimeout(function() {
$(window).one("scroll", scroller)
})
});
} else {
lastScrollTop = scrollTop;
$(window).one("scroll", scroller)
}
}
$(window).one("scroll", scroller);
/* Makes the element take up the entire height of the screen */
.full-height {
height: -o-calc(100vh - 111px);
/* opera */
height: -webkit-calc(100vh - 111px);
/* google, safari */
height: -moz-calc(100vh - 111px);

If you define height 100vh ,scroll event wont trigger
