Select variants by clicking their images stopped working on Simple Theme

Hello,

 

We currently use the Simple Theme for our store and have used the widely provided code below to accomplish what we wanted when clicking images to selectvariants in dropdown on product page.  Essentially when we clicked a product image variant (orange shirt), the dropdown would automatically change to "orange shirt."

 

For some reason this stopped working out of nowhere (we didn't change anything).  I realize the theme is no longer available in the Shopify Theme store but am wondering if someone may know how to help me get this working again?  Thanks in advance.

 

const selectVariantByClickingImage = {
  // Create variant images from productJson object
  _createVariantImage: function (product) {
    const variantImageObject = {};
    product.variants.forEach((variant) => {
      if (
        typeof variant.featured_image !== 'undefined' &&
        variant.featured_image !== null
      ) {
        const variantImage = variant.featured_image.src
          .split('?')[0]
          .replace(/http(s)?:/, '');
        variantImageObject[variantImage] =
          variantImageObject[variantImage] || {};
        product.options.forEach((option, index) => {
          const optionValue = variant.options[index];
          const optionKey = `option-${index}`;
          if (
            typeof variantImageObject[variantImage][optionKey] === 'undefined'
          ) {
            variantImageObject[variantImage][optionKey] = optionValue;
          } else {
            const oldValue = variantImageObject[variantImage][optionKey];
            if (oldValue !== null && oldValue !== optionValue) {
              variantImageObject[variantImage][optionKey] = null;
            }
          }
        });
      }
    });
    return variantImageObject;
  },
  _updateVariant: function (event, id, product, variantImages) {
    const arrImage = event.target.src
      .split('?')[0]
      .replace(/http(s)?:/, '')
      .split('.');
    const strExtention = arrImage.pop();
    const strRemaining = arrImage.pop().replace(/_[a-zA-Z0-9@]+$/, '');
    const strNewImage = `${arrImage.join('.')}.${strRemaining}.${strExtention}`;
    if (typeof variantImages[strNewImage] !== 'undefined') {
      product.variants.forEach((option, index) => {
        const optionValue = variantImages[strNewImage][`option-${index}`];
        if (optionValue !== null && optionValue !== undefined) {
          const selects = document.querySelectorAll('#'+ id + ' [class*=single-option-selector]');
          const options = selects[index].options;
          for (let option, n = 0; (option = options[n]); n += 1) {
            if (option.value === optionValue) {
              selects[index].selectedIndex = n;
              selects[index].dispatchEvent(new Event('change'));
              break;
            }
          }
        }
      });
    }
  },
  _selectVariant: function() {
    const productJson = document.querySelectorAll('[id^=ProductJson-');
    if (productJson.length > 0) {
      productJson.forEach((product) => {
        const sectionId = product.id.replace("ProductJson-", "shopify-section-");
        const thumbnails = document.querySelectorAll('#'+ sectionId + ' img[src*="/files/"]');
        if (thumbnails.length > 1) {
          const productObject = JSON.parse(product.innerHTML);
          const variantImages = this._createVariantImage(productObject);
          // need to check variants > 1
          if (productObject.variants.length > 1) {
            thumbnails.forEach((thumbnail) => {
              thumbnail.addEventListener('click', (e) =>
                this._updateVariant(e, sectionId, productObject, variantImages),
              );
            });
          }
        }
      });
    }
  },
};
if (document.readyState !== 'loading') {
  selectVariantByClickingImage._selectVariant();
} else {
  document.addEventListener(
    'DOMContentLoaded',
    selectVariantByClickingImage._selectVariant(),
  );
}

We are in the process of finishing up a new theme but was hoping for a quick fix on this until new one is ready to launch.
