Question

I can’t figure this out. I checked other questions regarding setting data attributes, seems to be a tricky enough thing.

The stripe button amount is purely for aesthetics, I’m trying to set it (‘data-amount’) each time a user updates the quantity select box.

Every time I change the quantity select an alert gives the correct amount and if I inspect the dom the ‘data-amount’ attribute appears to be set correctly but when I click the stripe button the modal shows the default data-amount, i.e nothing.

Anyone know how to do this?

view (form, select input not shown)

<div class="stripe-controls" align="center">
  <script src="https://button.stripe.com/v1/button.js" class="stripe-button"
      data-key="ENV['STRIPE_PUBLIC_KEY'] %>" data-amount="">
  </script>
</div>

coffeescript

$ ->
  $('#order_quantity').click(orderTotal)
  orderTotal()

orderTotal = ->
  quantity = $('#order_quantity').val()
  price = $('#ticket-price').data('url')
  total = quantity * price
  $('.stripe-button').attr('data-amount', total)
  alert total

Answer 1

Specify a custom amount using StripeCheckout.open().
