我在 javascript 方面不是最擅长的，并且对为什么我的咖啡脚本没有检索到条带令牌感到非常困惑。我检查了错误，它说卡返回零。我注意到如果我在错误页面上重新填写信用卡信息，它可以正常工作吗？

这是创建订阅的网址 /subscriptions/new?plan_id=1

这是一个信用卡错误，它指向 /subscriptions/

如果我在此页面上填写信用卡详细信息，则它可以工作并在条带上创建订阅。我在不是我的条纹表单视图的页面上收到此错误，并且可能导致问题

我收到此错误

Uncaught ReferenceError: Stripe is not defined subscriptions.js?body=1:5
(anonymous function) subscriptions.js?body=1:5
fire jquery.js?body=1:3049
self.fireWith jquery.js?body=1:3161
jQuery.extend.ready jquery.js?body=1:434
completed

这是我的看法

这是我的咖啡脚本文件，感谢 rails cast

jQuery ->
  Stripe.setPublishableKey($('meta[name="stripe-key"]').attr('content'))
  subscription.setupForm()

subscription =
  setupForm: ->
    $('#new_subscription').submit ->
      $('input[type=submit]').attr('disabled', true)
      if $('#card_number').length
        subscription.processCard()
        false
      else
        true

  processCard: ->
    card =
      number: $('#card_number').val()
      cvc: $('#card_code').val()
      expMonth: $('#card_month').val()
      expYear: $('#card_year').val()
    Stripe.createToken(card, subscription.handleStripeResponse)

  handleStripeResponse: (status, response) ->
    if status == 200
      $('#subscription_stripe_card_token').val(response.id)
      $('#new_subscription')[0].submit()
    else
      $('#stripe_error').text(response.error.message)
      $('input[type=submit]').attr('disabled', false)

如果您只想在结帐页面上包含 Stripe javascript，您可以将 Ryan Bates 的咖啡脚本包装在一个if语句中。

if typeof(Stripe) != "undefined"
  Stripe.setPublishableKey($('meta[name="stripe-key"]').attr('content'))
  subscription.setupForm()
