javascript - 错误: "undefined local variable or method ' e'"inside RegistrationsController

Question

我在使用 Stripe Checkout 将电子邮件从 JS 传递到 Rails 时遇到问题。我通过堆栈跟踪在第 21 行和第 25 行不断收到错误未定义的局部变量或方法 'e'。任何帮助将不胜感激。

这是我的代码:

Rails 代码:

def create
   **line 21:** @registration = Registration.new registration_params.merge(email: stripe_params[:stripeEmail],
                                                               card_token: stripe_params[:stripeToken]) //ERROR
    raise "Please, check registration errors" unless @registration.valid?
    @registration.process_payment
    @registration.save
    redirect_to @registration, notice: 'Registration was successfully created.'
  rescue
    **line 25:** flash[:error] = e.message // ERROR
    render :new
  end

JS代码:

<script src='https://checkout.stripe.com/checkout.js'></script>
<script>
  var handler = StripeCheckout.configure({
    key: 'pk_test_xxxxxx',
    token: function(token) {
      // Use the token to create the charge with a server-side script.
      // You can access the token ID with `token.id`
    }
  });

  jQuery('#customButton').on('click', function(e) {
    // Open Checkout with further options
    handler.open({
      name: 'The Climb',
      description: 'Individual',
      email: 'asdfasdf999@asdf.com',
      amount: 3500
    });
    e.preventDefault();
  });

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

第 24 行应该是:

rescue => e
