Scroll to anchor with slash at the end - javascript

I have a website where sections have # and menu items should scroll to them. Due to setup of website it's required that my URL have / (slash) at the end.
For example website.com/about/
So anchor would be website.com/about/#team/
When there's / at the end of URL, scroll to anchor doesn't work. I don't have any jQuery on website so simple jump to section doesn't work either. When I remove / it works.
Is there jQuery which I can use for that purpose? I tried bunch of jQuery but without success.
$(document).ready(function(){
// Add smooth scrolling to all links
$("a").on('click', function(event) {
event.preventDefault();
var hash = this.hash;
$('html, body').animate({
scrollTop: $(hash).offset().top
}, 800, function(){
window.location.hash = hash;
});
});
});

As you said you cant change hash pattern then you have to do reverse process: remove dash from this.hash before putting $(hash).offset() method
$(document).ready(function(){
$('a').click(function(event) {
// Store hash
event.preventDefault();
var hashWithoutDash = this.hash.replace("/",""); // remove dash from hash to make $(hashWithoutDash).offset() worked
$('html, body').animate({
scrollTop: $(hashWithoutDash).offset().top
}, 1000, function() {
window.location.hash = this.hash; // keep actual hash with dash
});
});
});

Scroll to a div using jQuery from other page

When I click href #demo-1 from home page to another page with ection id='demo-1'.
How when loading the page with id='demo-1', that it will scroll down from the top of the page.
If I use https://stackoverflow.com/a/3432718/6891215 it will jerk and not scroll from the top of the page down to that section.
Many thanks!
The code below allows you to scroll on both same and external pages. To make the link work you need to give it a class .scroll. If you're linking to an anchor link on an external page, give the link a data-target="external" as well.
$(document).ready(function() {
$('html, body').scrollTop(0);
var str = window.location.href;
if(str.indexOf('#') > -1) {
var anchor = str.substring(str.indexOf('#'));
setTimeout(function() {
$('html, body').animate({scrollTop: $(anchor).offset().top}, 'slow');
}, 100);
}
$('a.scroll').click(function(e) {
var trg = $(this).attr('data-target');
if(trg != 'external') {
e.preventDefault();
var href = $(this).attr('href');
$('html, body').animate({scrollTop: $(href).offset().top}, 'slow');
}
});
});
The link to an anchor on an external page will look like this:
DEMO 2
Also, you can link to an anchor on the same page. In this case, you won't need to add any data-target. I wrote the script the way that is supports both:
Go TO DEMO 3

How to make this scroll 120px above the content?

When I apply this script, it goes to the link but I want it to go 120px above the content it is linked to.
Here is the code:
<script>
$(document).ready(function(){
// Add smooth scrolling to all links
$("a").on('click', function(event) {
// Make sure this.hash has a value before overriding default behavior
if (this.hash !== 0) {
// 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
}, 800, function(){
// Add hash (#) to URL when done scrolling (default click behavior)
window.location.hash = hash;
});
} // End if
});
});
</script>
EDIT #02
Here is my HTML, CSS and Java for those who are wondering:
https://codepen.io/crosso_7/pen/WYegpY
Simply subtract the amount of pixels from your calculation.
$(document).ready(function(){
// Add smooth scrolling to all links
$("a").on('click', function(event) {
// Make sure this.hash has a value before overriding default behavior
if (this.hash !== 0) {
// 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 -120
}, 800, function(){
// Add hash (#) to URL when done scrolling (default click behavior)
window.location.hash = hash;
});
} // End if
});
});
the problem is window.location.hash = hash; after animate it do second action which is same with default action. Replace it with history.pushState(null, null, hash); to rewrite the url history and add hash
$('html, body').animate({
scrollTop: $(hash).offset().top - 120
}, 800, function() {
// Add hash (#) to URL when done scrolling (default click behavior)
//window.location.hash = hash;
history.pushState(null, null, hash);
});

Remove anchor link after scrolling - works also on links from another page

I've set up a single page website with smooth scrolling that strips the anchor link from the URL after smooth scrolling. Here's the jQuery I'm using :
$(function() {
$('a.page-scroll').on('click', function(event) {
var $anchor = $(this);
$('html, body').stop().animate({
scrollTop: $($anchor.attr('href')).offset().top - 60
}, 1000, 'easeInOutExpo');
event.preventDefault();
});
});
Everything works great until I added other pages. I can't get the anchor link to strip out after a link like <a class="page-scroll" href="../#contact">Contact</a> on another external page.
I've searched high and low on SO but can't find a solution that works.
I don't totally care about the smooth scrolling if the link is from an external page. What I need most is to navigate / scroll to the id section of the main page (with offset to accommodate fixed navigation) and remove the anchor link from the browser URL window when the link is from an external page (from other pages on my website, or from other websites).
I've tried this also, but it likewise only works on internal links on to an id on the same page :
<script>
$(function() {
$('a[href*=#]:not([href=#])').click(function() {
if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
var target = $(this.hash);
target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
if (target.length) {
$('html,body').animate({
scrollTop: target.offset().top - 60
}, 1000);
return false;
}
}
});
});
</script>
I've also tried this with no luck :
<script type="text/javascript">
(function($) {
$(document).ready(function() {
var url=document.URL.split("#");
var ancher=url[1];
$('html, body').animate({
'scrollTop': $('#'+ancher).offset().top - 60
}, 5000);
});
})(jQuery);
</script>
Any New Year's Eve help would be most appreciated so I can get this project wrapped up!
It's possible I don't understand the extent of the question, but I believe you are trying to make it so the href doesn't fire on pages that are wanting to scroll but does on pages that are linking to other pages and not sections within the page itself. Perhaps something like this would work for you:
$(function() {
$('a.page-scroll').bind('click', function(event) {
var $anchor = $(this);
if ($anchor[0].href[0] === '#') {
$('html, body').stop().animate({
scrollTop: $($anchor.attr('href')).offset().top - 60
}, 1000, 'easeInOutExpo');
event.preventDefault();
return false;
} else {
return true;
}
});
});
What this does is look to see that the leading character in the href is a # implying that its a link to a section within itself.
Let me know if that helps and/or if I'm on the right track.
ps: I left the .bind in there because I don't know what version of jQuery you are on, but the newer syntax is to use .on
Happy New Year
Just to append slightly in regards to making it so that deep links to the main page go to the appropriate section but don't have the hash tag:
You can remove that 'hash' variable from window.location, but if you attempt to remove the hashtag entirely, it will cause the browser to refresh. This will also cause the viewer to lose the spot (thus removing the deep link's purpose).
To change the hash tag value (keeps the #):
window.location.hash = ''; // clears the hash tag
To remove the hash tag and its value (clears the # and everything past it):
window.location.href = window.location.href.substr(0, window.location.href.indexOf('#')); // this causes a browser refresh
And if it's not wholly apparent, you would run it on page load
$(document).ready(function() {
if (typeof(window.location.hash) !== 'undefined' && window.location.hash.length > 0) {
window.location.hash = ''; // will clear the hash anytime someone arrives with a hash tag
}
});
For a page with smooth scrolling try to use replaceState().
It will remove the hashtag at anchor link from the browser URL window (without page reloading).
// smooth scrolling
function scrollTo(selectors)
{
if(!$(selectors).length) return;
var selector_top = $(selectors).offset().top - 0;
$('html,body').animate({ scrollTop: selector_top }, 'slow');
}
// do scroll and clear the hash tag
$(window).on('load', function(){
if( typeof(location.hash) !== 'undefined' && location.hash.length ) {
scrollTo(location.hash);
history.replaceState(null, null, location.pathname);
}
});

Load page at specific point with jQuery (without animation!)

I want to load a page at a specific div on my page without animating to that point. Below is the code I'm using right now which animates to said div. I haven't been able to figure out how to do this same function without animation.
jQuery:
if(window.location.hash) {
var hash = window.location.hash;
var link = $("[href='"+ hash +"']");
if ( hash == "#specific-url" ) {
$('html, body').animate({
scrollTop: $("#specific-div").offset().top
}, 1000);
}
instead of this:
$('html, body').animate({
scrollTop: $("#specific-div").offset().top
}, 1000);
do this:
$(document).scrollTop($("#specific-div").offset().top);
In you code you were trying to animate the html,body of your document, so as you want to move at a specific location in your document i think you can directly set the .scrollTop() of your document the way i suggested to you above.
One way set animate time 0ms
if(window.location.hash) {
var hash = window.location.hash;
var link = $("[href='"+ hash +"']");
if ( hash == "#specific-url" ) {
$('html, body').animate({
scrollTop: $("#specific-div").offset().top
}, 0);
}
You can use
.scrollTop()
$(document).scrollTop($("#specific-div").offset().top);
.scrollIntoView()
$("#specific-div")[0].scrollIntoView(true);
or
document.getElementById(specific-div).scrollIntoView(true);

jquery scrolling won't scroll from exact location

I'm using the following jquery to make my links scroll to the next div. However, I've run into a problem. From the top of the page the script works fine. As soon as I click a link from another div (another link further down the page) the script only scrolls so far either up or down but not to the next specified div. How can I make the script scroll fully from the current location of where the link is located?
$(function() {
$('#nav a').bind('click',function(event){
var $anchor = $(this);
$('html, body, #container, .main').stop().animate({
scrollTop: $($anchor.attr('href')).offset().top
}, 1500,'easeInOutExpo');
event.preventDefault();
});
});
You have a error here:
scrollTop: $($anchor.attr('href')).offset().top
//------^^^^^^^---------------------------------this itself a selector
change to this and try with:
scrollTop: $anchor.attr('href').offset().top
or this one too:
$('#nav a').bind('click',function(event){
var $anchor = $(this).attr('href');
$('html, body, #container, .main').stop().animate({
scrollTop: $($anchor).offset().top
}, 1500,'easeInOutExpo');
event.preventDefault();
});
CHECKOUT IN FIDDLE
You're not calling the correct spot...
this should do the trick... Set the anchor point first.
$(function() {
$('#nav a').bind('click',function(event){
var $anchor = $(this).attr('href');
$('html, body, #container, .main').stop().animate({
scrollTop: $($anchor).offset().top
}, 1500,'easeInOutExpo');
event.preventDefault();
});
});
ok, so I've made you a JSFiddle, the js-code I rewrote to the code below, but you can have a have a look at the full thing here: http://jsfiddle.net/re7Xc/
$(function() {
$('a.scrolltonext').click(function(event){
event.preventDefault();
var parentblock = $(this).parent();
var nextblock = parentblock.next();
//nextblock.css('background-color','#00f');
if(nextblock.size()>0) {
$('html, body').stop().animate({
'scrollTop': nextblock.offset().top
}, 800);
}
});
});
the catch in this script though is that I put the links in the div itself, so it's not in a #nav somewhere. So you'd have to rewrite that part if you put the links in your #nav!
I put an if-statement in there as well, because I thought it'd be better if you check if there is a next-div first, before scrolling there.
Hope it makes some sense, and let me know if it works for you!
cheers
