Hello, i am writing this message for anyone who seems to have the same problem as I did, Let me run you through it basically when I first click on any of my products that have a variant they all appear okay, however as soon I switch to a different colour variant the ADD TO CART BUTTON appears grey and I am not able to click it, I have looked at many different questions however I was not able to find a solution, So I did some looking into the code.
In fact my problem was code-related to be more precise the problem was in the media-gallery.js The code was incorrect.
This is the old code:
if (!customElements.get('media-gallery')) {
customElements.define(
'media-gallery',
class MediaGallery extends HTMLElement {
constructor() {
super();
this.elements = {
liveRegion: this.querySelector('[id^="GalleryStatus"]'),
viewer: this.querySelector('[id^="GalleryViewer"]'),
thumbnails: this.querySelector('[id^="GalleryThumbnails"]'),
};
this.mql = window.matchMedia('(min-width: 750px)');
if (!this.elements.thumbnails) return;
this.elements.viewer.addEventListener('slideChanged', debounce(this.onSlideChanged.bind(this), 500));
this.elements.thumbnails.querySelectorAll('[data-target]').forEach((mediaToSwitch) => {
mediaToSwitch
.querySelector('button')
.addEventListener('click', this.setActiveMedia.bind(this, mediaToSwitch.dataset.target));
});
if (this.dataset.desktopLayout.includes('thumbnail') && this.mql.matches) this.removeListSemantic();
}
onSlideChanged(event) {
const thumbnail = this.elements.thumbnails.querySelector(
`[data-target="${event.detail.currentElement.dataset.mediaId}"]`
);
this.setActiveThumbnail(thumbnail);
}
setActiveMedia(mediaId) {
const activeMedia =
this.elements.viewer.querySelector(`[data-media-id="${mediaId}"]`) ||
this.elements.viewer.querySelector('[data-media-id]');
if (!activeMedia) {
return;
}
this.elements.viewer.querySelectorAll('[data-media-id]').forEach((element) => {
element.classList.remove('is-active');
});
activeMedia?.classList?.add('is-active');
this.preventStickyHeader();
window.setTimeout(() => {
if (!this.mql.matches || this.elements.thumbnails) {
activeMedia.parentElement.scrollTo({ left: activeMedia.offsetLeft });
}
const activeMediaRect = activeMedia.getBoundingClientRect();
// Don't scroll if the image is already in view
if (activeMediaRect.top > -0.5) return;
const top = activeMediaRect.top + window.scrollY;
window.scrollTo({ top: top, behavior: 'smooth' });
});
this.playActiveMedia(activeMedia);
if (!this.elements.thumbnails) return;
const activeThumbnail = this.elements.thumbnails.querySelector(`[data-target="${mediaId}"]`);
this.setActiveThumbnail(activeThumbnail);
this.announceLiveRegion(activeMedia, activeThumbnail.dataset.mediaPosition);
}
setActiveThumbnail(thumbnail) {
if (!this.elements.thumbnails || !thumbnail) return;
this.elements.thumbnails
.querySelectorAll('button')
.forEach((element) => element.removeAttribute('aria-current'));
thumbnail.querySelector('button').setAttribute('aria-current', true);
if (this.elements.thumbnails.isSlideVisible(thumbnail, 10)) return;
this.elements.thumbnails.slider.scrollTo({ left: thumbnail.offsetLeft });
}
announceLiveRegion(activeItem, position) {
const image = activeItem.querySelector('.product__modal-opener--image img');
if (!image) return;
image.onload = () => {
this.elements.liveRegion.setAttribute('aria-hidden', false);
this.elements.liveRegion.innerHTML = window.accessibilityStrings.imageAvailable.replace('[index]', position);
setTimeout(() => {
this.elements.liveRegion.setAttribute('aria-hidden', true);
}, 2000);
};
image.src=image.src;
}
playActiveMedia(activeItem) {
window.pauseAllMedia();
const deferredMedia = activeItem.querySelector('.deferred-media');
if (deferredMedia) deferredMedia.loadContent(false);
}
preventStickyHeader() {
this.stickyHeader = this.stickyHeader || document.querySelector('sticky-header');
if (!this.stickyHeader) return;
this.stickyHeader.dispatchEvent(new Event('preventHeaderReveal'));
}
removeListSemantic() {
if (!this.elements.viewer.slider) return;
this.elements.viewer.slider.setAttribute('role', 'presentation');
this.elements.viewer.sliderItems.forEach((slide) => slide.setAttribute('role', 'presentation'));
}
}
);
}
I have then went on and uptaded the previous Code and was left with the Code down below that has fixed my problem!
if (!customElements.get('media-gallery')) {
customElements.define(
'media-gallery',
class MediaGallery extends HTMLElement {
constructor() {
super();
this.elements = {
liveRegion: this.querySelector('[id^="GalleryStatus"]'),
viewer: this.querySelector('[id^="GalleryViewer"]'),
thumbnails: this.querySelector('[id^="GalleryThumbnails"]'),
};
this.mql = window.matchMedia('(min-width: 750px)');
if (!this.elements.viewer) {
console.error('Viewer element not found');
return;
}
if (!this.elements.thumbnails) {
console.warn('Thumbnails element not found');
} else {
this.elements.viewer.addEventListener('slideChanged', debounce(this.onSlideChanged.bind(this), 500));
this.elements.thumbnails.querySelectorAll('[data-target]').forEach((mediaToSwitch) => {
const button = mediaToSwitch.querySelector('button');
if (button) {
button.addEventListener('click', this.setActiveMedia.bind(this, mediaToSwitch.dataset.target));
} else {
console.warn('Button not found for media:', mediaToSwitch);
}
});
if (this.dataset.desktopLayout.includes('thumbnail') && this.mql.matches) {
this.removeListSemantic();
}
}
}
onSlideChanged(event) {
const thumbnail = this.elements.thumbnails.querySelector(
`[data-target="${event.detail.currentElement.dataset.mediaId}"]`
);
if (!thumbnail) {
console.error('Thumbnail not found for media ID:', event.detail.currentElement.dataset.mediaId);
return;
}
this.setActiveThumbnail(thumbnail);
}
setActiveMedia(mediaId) {
const activeMedia =
this.elements.viewer.querySelector(`[data-media-id="${mediaId}"]`) ||
this.elements.viewer.querySelector('[data-media-id]');
if (!activeMedia) {
console.error('Active media element not found for ID:', mediaId);
return;
}
this.elements.viewer.querySelectorAll('[data-media-id]').forEach((element) => {
element.classList.remove('is-active');
});
activeMedia.classList.add('is-active');
this.preventStickyHeader();
window.setTimeout(() => {
if (!this.mql.matches || this.elements.thumbnails) {
activeMedia.parentElement.scrollTo({ left: activeMedia.offsetLeft });
}
const activeMediaRect = activeMedia.getBoundingClientRect();
// Don't scroll if the image is already in view
if (activeMediaRect.top > -0.5) return;
const top = activeMediaRect.top + window.scrollY;
window.scrollTo({ top, behavior: 'smooth' });
});
this.playActiveMedia(activeMedia);
if (!this.elements.thumbnails) return;
const activeThumbnail = this.elements.thumbnails.querySelector(`[data-target="${mediaId}"]`);
if (!activeThumbnail) {
console.error('Active thumbnail not found for media ID:', mediaId);
return;
}
this.setActiveThumbnail(activeThumbnail);
this.announceLiveRegion(activeMedia, activeThumbnail.dataset.mediaPosition);
}
setActiveThumbnail(thumbnail) {
if (!this.elements.thumbnails || !thumbnail) return;
this.elements.thumbnails
.querySelectorAll('button')
.forEach((element) => element.removeAttribute('aria-current'));
thumbnail.querySelector('button').setAttribute('aria-current', true);
if (this.elements.thumbnails.isSlideVisible(thumbnail, 10)) return;
this.elements.thumbnails.slider.scrollTo({ left: thumbnail.offsetLeft });
}
announceLiveRegion(activeItem, position) {
const image = activeItem.querySelector('.product__modal-opener--image img');
if (!image) return;
image.onload = () => {
this.elements.liveRegion.setAttribute('aria-hidden', false);
this.elements.liveRegion.innerHTML = window.accessibilityStrings.imageAvailable.replace('[index]', position);
setTimeout(() => {
this.elements.liveRegion.setAttribute('aria-hidden', true);
}, 2000);
};
image.src=image.src; // Trigger image load event
}
playActiveMedia(activeItem) {
window.pauseAllMedia();
const deferredMedia = activeItem.querySelector('.deferred-media');
if (deferredMedia) deferredMedia.loadContent(false);
}
preventStickyHeader() {
this.stickyHeader = this.stickyHeader || document.querySelector('sticky-header');
if (!this.stickyHeader) return;
this.stickyHeader.dispatchEvent(new Event('preventHeaderReveal'));
}
removeListSemantic() {
if (!this.elements.viewer.slider) return;
this.elements.viewer.slider.setAttribute('role', 'presentation');
this.elements.viewer.sliderItems.forEach((slide) => slide.setAttribute('role', 'presentation'));
}
}
);
}
If anyone has the same issue you are more than welcome to copy this code and paste it into your media-gallery.js to see if it will fix the problem.
