Answer 1

OR you can just use the following code before clicking the stripe button ;-)

StripeCheckout.__app.configurations.button0.amount = 1234;

$('#stripe-button').click();

Answer 2

Turns out that to have a dynamic data-amount for the stripe payment, you have to use Custom Checkout instead of Simple Checkout. This code did the trick.

      <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>

As @awwester said, you can use Stripe's Custom Checkouts. Although, I found an easier way to do this through jQuery simply by remounting the script with the changed variable each time they increase the quantity:

$("#stripe-form").html(
  '<input type="hidden" name="amount" value="' +
    totalCost.replace(".", "") +
    '" /><input type="hidden" name="currency" value="usd" /><script src="https://checkout.stripe.com/checkout.js" class="stripe-button" data-key="pk_test_123123123123" data-amount="' +
    totalCost.replace(".", "") +
    '" data-zip-code="true" data-currency="usd" data-billing-address="true" data-shipping-address="true" data-name="Company Name" data-description="Product Name" data-image="https://image" data-locale="auto"></script>'
);
