I am working on an ecommerce store(shopify/liuquid).
I want to scroll smoothly to different hashs.
Now because this is a CMS, I have had to add some attributes via editor or manually with JS.
Here I give it the href
$(document).ready(function() {
$(".hero__cta").addClass("scroll");
$(".hero__cta").attr("href", "#section2")
});
If you go to the website, just under the main image, #the new entries# title, has this is the markup:
<a id="section2"> </a>
And here is the JS function:
$(document).ready(function(){
$("a").on('click', function(event) {
if (this.hash !== "") {
event.preventDefault();
var hash = this.hash;
$('html, body').animate({scrollTop: $(hash).offset().top}, 800,
function() {
window.location.hash = hash;
}
);
}
});
});
So if you go to the site and click on the CTA button, it should scroll smoothly to that anchor. Works on a Codepen etc, but not on the Shopify platform.
I get :
Uncaught TypeError: Cannot read property 'top' of undefined
at HTMLAnchorElement.
The site is live here:
https://www.toptrendshopping.com/
Oh and how and where do I add an IntersectionObserver polifill for this?
I have found a fix. As you can see, this works now on the live site.
$(document).ready(function(){
$(".hero__cta").attr("href", "#two");
$('a[href*="#"]')
// Remove links that don't actually link to anything
.not('[href="#"]')
.not('[href="#0"]')
.click(function(event) {
// On-page links
if (
location.pathname.replace(/^\//, '') == this.pathname.replace(/^\//, '')
&&
location.hostname == this.hostname
) {
// Figure out element to scroll to
var target = $(this.hash);
target = target.length ? target : $('[name=' + this.hash.slice(1) + ']');
// Does a scroll target exist?
if (target.length) {
// Only prevent default if animation is actually gonna happen
event.preventDefault();
$('html, body').animate({
scrollTop: target.offset().top
}, 1000, function() {
// Callback after animation
// Must change focus!
var $target = $(target);
$target.focus();
if ($target.is(":focus")) { // Checking if the target was focused
return false;
} else {
$target.attr('tabindex','-1'); // Adding tabindex for elements not focusable
$target.focus(); // Set focus again
};
});
}
}
});
});
Found this on CSS tricks, still do not entirely why all this is required but work for now.
And a little extra, if you want to add a polyfill on a Shopify store, do it in the head section of the "theme.liquid" file.

I need help with this scrollto code snippet. The problem is that I need to set an offset to account for my menu. Without the offset the header that I scroll to gets buried underneath the menu. See for yourselves here:https://julyfx.mystagingwebsite.com/stanford-mba-msx-essay-topic-analysis-examples/
Would anyone happen to have a suggestion?
Thank you! Leah
<script type="text/javascript">

Should be relatively easy: If your header is for example 85px high, you can just add these 85px to the offset in your code, so this line
scrollTop: target.offset().top
becomes
scrollTop: target.offset().top - 85
that way the window will scroll 85px less than calculated, so the section will not be hidden behind the header.
Just a suggestion have you tried something like:
window.scrollTo({top: (jQuery('#2').position().top-jQuery('header').height()), behavior: 'smooth' })
?
Where #2 would be taken from your this.hash target above?
Any help with this is greatly appreciated! I have a button at the top of my product page for a sizing chart which anchor scrolls to the sizing chart image at the bottom of the page. However, upon page load, the page automatically scrolls down to the sizing chart. What can I modify so that the page does not automatically scroll down to the anchor? Here is my JS:
// Select all links with hashes
$('a[href*="#"]')
// Remove links that don't actually link to anything
.not('[href="#"]')
.not('[href="#0"]')
.click(function(event) {
// On-page links
if (
location.pathname.replace(/^\//, '') == this.pathname.replace(/^\//, '')
&&
location.hostname == this.hostname
) {
// Figure out element to scroll to
var target = $(this.hash);
target = target.length ? target : $('[name=' + this.hash.slice(1) + ']');
// Does a scroll target exist?
if (target.length) {
// Only prevent default if animation is actually gonna happen
event.preventDefault();
$('html, body').animate({
scrollTop: target.offset().top
}, 1000, function() {
// Callback after animation
// Must change focus!
var $target = $(target);
$target.focus();
if ($target.is(":focus")) { // Checking if the target was focused
return false;
} else {
$target.attr('tabindex','-1'); // Adding tabindex for elements not focusable
$target.focus(); // Set focus again
};
});
}
}
});
I assume you mean that the page scrolls down when it is reloaded.
It is default browsers behaviour to scroll the page down to the point the user were the last time she/he visited the page.
To avoid that scroll to top before the page is closed:
$(window).on('beforeunload', function() {
$(window).scrollTop(0);
});

I have navbar with items. When i click on item it scrolls me down to the div. For example i click on contact and it scrolls me to contact. My problem is that i have fixed navbar. And my navbar hide heading of section. So when i click on contact it scrolls me down to contact but heading is behind navbar.
This is my script i need to add something like scroll - 55px or something like that but i dont know how.
<script>
// Select all links with hashes
$('a[href*="#"]')
// Remove links that don't actually link to anything
.not('[href="#"]')
.not('[href="#0"]')
.click(function(event) {
// On-page links
if (
location.pathname.replace(/^\//, '') == this.pathname.replace(/^\//, '')
&&
location.hostname == this.hostname
) {
// Figure out element to scroll to
var target = $(this.hash);
target = target.length ? target : $('[name=' + this.hash.slice(1) + ']');
// Does a scroll target exist?
if (target.length) {
// Only prevent default if animation is actually gonna happen
event.preventDefault();
$('html, body').animate({
scrollTop: target.offset().top
}, 1000, function() {
// Callback after animation
// Must change focus!
var $target = $(target);
$target.focus();
if ($target.is(":focus")) { // Checking if the target was focused
return false;
} else {
$target.attr('tabindex','-1'); // Adding tabindex for elements not focusable
$target.focus(); // Set focus again
};
});
}
}
});
</script>
You could first check if link clicked is /contact and then apply a different scroll like this:
if (target.length) {
// Only prevent default if animation is actually gonna happen
event.preventDefault();
let scrollOffset = 0;
if ($(this).attr('href') === '/contact') {
scrollOffset = 55;
}
$('html, body').animate({
scrollTop: target.offset().top + scrollOffset
}, 1000, function() {
// Callback after animation
// Must change focus!
var $target = $(target);
$target.focus();
if ($target.is(":focus")) { // Checking if the target was focused
return false;
} else {
$target.attr('tabindex','-1'); // Adding tabindex for elements not focusable
$target.focus(); // Set focus again
};
});
}
It's not the most elegant solution but that should do the trick.
If you could share html as well it would be easy to understand. Anyways, as i understood the problem is with fixed navbar. When Positioning absolute/fixed is used the div is then out of the flow of the document. To get elements start immediately after header you would need to give elements container a margin-top equal to the height of the header. This is the easiest solution. You do not need to do anything with js.
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);
}
});
