Shopify 商店 刷新購物車內容。 AJAX 請求

Question

我有產品頁面，我shop now btn。 當用戶單擊此按鈕時，頁面將打開帶有自定義 ajax 模板內容的購物車抽屜。

我用自己的邏輯重寫了點擊事件。 我用的是AJAX，自己發添加商品請求。 產品正在添加但未顯示在購物車抽屜中。 只有在重新加載頁面后才會出現。

問題是我可以刷新購物車內容嗎？ 我正在嘗試通過內部 html 過去內容模板。但它看起來不像液體格式。

這是模板

Answer 1

通常，有一些方法（js-function）可以讓你用新項目重建購物車。 您需要檢查負責顯示抽屜車的 js 代碼

Answer 2

因此，需要觸發一些可以在 theme.js 文件中找到的事件。 就我而言，我需要添加以下內容：

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