javascript – 更新条带数据量

我正在将Stripe实施到一个django网站,除了一部分外,一切正常.在我的购物车中,用户可以更新更改总数的项目.除了在Stripe Checkout js脚本上设置数据量之外,一切正常.

当页面加载时,一切都很好,但是如果客户更改了他们的购物车,则数据量不会更新.我有另一个显示总数的框,这个数量更新很好.

<!-- here is the script tag in HTML-->
<script
id="stripe-script"
src="https://checkout.stripe.com/checkout.js" 
class="stripe-button"
data-image="{% static 'img/marketplace.png' %}"
data-key="{{ STRIPE_PUBLIC_KEY }}"
data-name="Serendipity Artisan Blends"
data-description="Purchase Items"
data-amount="{{ cart_stripe_total }}">
</script>

然后我尝试更新的javascript是这样的：

function updateTotal(amount) {
    /* update the total in the cart in both the table cell and
        in the stripe button data-amount */
    var totalStr = shoppingTotalCell.text().replace('$', ''),
        originalTotal = parseFloat(totalStr),
        newTotal = originalTotal + amount,
        newTotalStripe = newTotal * 100,
        newTotalStr = newTotal.toFixed(2),
        script = $('#stripe-script');

    shoppingTotalCell.text('$' + newTotalStr);

    console.log(script.data("amount"));
    // this returns the correct original amount

    script.data("amount", newTotalStripe);

    console.log(script.data("amount"));
    /* this returns the updated amount, however the HTML data-amount 
        attribute does not update. */
  }

解决方法:

事实证明,要获得条带付款的动态数据量,您必须使用Custom Checkout而不是简单结帐.这段代码就行了.

      <button class="btn btn-primary btn-lg" id="stripe-button">
        Checkout <span class="glyphicon glyphicon-shopping-cart"></span>
      </button>

      <script>
        $('#stripe-button').click(function(){
          var token = function(res){
            var $id = $('<input type=hidden name=stripeToken />').val(res.id);
            var $email = $('<input type=hidden name=stripeEmail />').val(res.email);
            $('form').append($id).append($email).submit();
          };

          var amount = $("#stripeAmount").val();
          StripeCheckout.open({
            key:         '{{ STRIPE_PUBLIC_KEY }}',
            amount:      amount,
            name:        'Serendipity Artisan Blends',
            image:       '{% static "img/marketplace.png" %}',
            description: 'Purchase Products',
            panelLabel:  'Checkout',
            token:       token
          });

          return false;
        });
      </script>
