Shopify 商店 刷新购物车内容。 AJAX 请求

Question

I have product page on which I have shop now btn. When user clicks on this button, page opens cart drawer with custom ajax template content.

I rewrited click event with my own logic. I use AJAX and send request for adding product by myself. Products are adding but is not showing in the cart drawer. Only after reloading page it is appearing.

Question is to can I refresh cart content? I'm trying to past content template via inner html. But it is looks like not liquid format.

Here is the template

 <script id="CartTemplate" type="text/template">
{% render 'banana-stand-cart-top-container' %}
{% raw %}
<div class="drawer__scrollable">
  {{#items}}
  <div class="ajaxcart__product appear-animation appear-delay-{{animationRow}}">
  <div class="ajaxcart__row">

      <div class="grid__item one-third">

      </div>
      <div class="grid__item two-thirds">
        <div class="ajaxcart__product-name--wrapper">
          <a href="{{url}}" class="ajaxcart__product-name">{{{name}}}</a>
          {{#if variation}}
            <div class="ajaxcart__product-meta">{{variation}}</div>
          {{/if}}
          {{#if selling_plan_name}}

Answer 1

Usually, there is some way (js-function) that allows you to rebuild the cart with new items. You need to check the js-code that is responsible for showing the drawer-cart

Answer 2

So, need fire some event that you can find in your theme.js file. In my case I needed to add this:

 document.dispatchEvent(new CustomEvent('cart:build', {
    detail: {
      cart: cart
    }
 }));
