Theme js for add to cart code 


key: '_addToCart',
      value: function _addToCart(event) {
        var _this7 = this;

        if (!this.options['useAjaxCart']) {
          console.log("goes to cart page")
          return; // When using a cart type of page, we just simply redirect to the cart page

        event.preventDefault(); // Prevent form to be submitted

        var addToCartButton = this.element.querySelector('.ProductForm__AddToCart');
        // First, we switch the status of the button
        addToCartButton.setAttribute('disabled', 'disabled');
        document.dispatchEvent(new CustomEvent('theme:loading:start'));

        // Then we add the product in Ajax
        var formElement = this.element.querySelector('form[action*="/cart/add"]');

        fetch(window.routes.cartAddUrl + '.js', {
          body: JSON.stringify(__WEBPACK_IMPORTED_MODULE_2__helper_Form__["default"].serialize(formElement)),
          credentials: 'same-origin',
          method: 'POST',
          headers: {
            'Content-Type': 'application/json',
            'X-Requested-With': 'XMLHttpRequest' // This is needed as currently there is a bug in Shopify that assumes this header
        }).then(function (response) {
          document.dispatchEvent(new CustomEvent('theme:loading:end'));
          if (response.ok) {
            // We simply trigger an event so the mini-cart can re-render
            _this7.element.dispatchEvent(new CustomEvent('product:added', {
              bubbles: true,
              detail: {
                variant: _this7.currentVariant,
                quantity: parseInt(formElement.querySelector('[name="quantity"]').value)
          } else {
            response.json().then(function (content) {

Hi @AvidBrio,

I checked and ajax cart only support product page, when you add code anywhere else it wont work. It's bundled by the theme and you can't edit it.

So if you want ajax cart at item products you can just contact theme support or hire an expert.

Because it is a complex request and it is difficult for anyone to guide you in detail. You can post on the group, there will be many experts to help you:

Hope it helps!

If my answer can help you solve your issue, please kindly mark it as a solution. Thank you and good luck.
