    alipay: "true",
    // locale: "zh-CN",
    currency: "CNY",
    token: function(token) {
      // Use the token to create the charge with a server-side script.
      // You can access the token ID with `token.id`
    }
  })
  $('#customButton').on('click', function(e) {
    // Open Checkout with further options
    handler.open({

      description: 'MixRadio Premium Subscription',
      amount: 499
    });
    e.preventDefault();
  });

  // Close Checkout on page navigation
  $(window).on('popstate', function() {
    handler.close();
  });
</script>

Unfortunately, stripe disabled alipay in checkout

You can use the Stripe Element to achieve this.
