Stripe支付出现“Uncaught TypeError: Cannot read property 'submit' of null”错误

Question

我正在将Stripe支付集成到我的应用程序中。我更换了Stripe默认的“使用信用卡付款”按钮，并替换为我定制的一个按钮。在这样做之后，测试模式成功弹出，我可以输入测试凭据。然而，当我提交测试付款并且它被批准时，它仍然停留在相同的pin页面上，而不是转到我为其创建的charges页面。

注意：在我替换默认的Stripe付款按钮为我的新定制按钮之前，应用程序从Stripe付款过渡到charges create.html.erb页面都很好。

此外，查看开发人员工具时，我确实注意到它在我提交测试付款时读取：

Uncaught TypeError: Cannot read property 'submit' of null 

我认为这是指我下面的代码，当我提交chargeForm时。

有人遇到过这个问题或者知道我该如何解决吗？非常感谢！

app/views/pins/_details.html.erb

        <%= form_tag charges_path, id: 'chargesForm' do %>
          <script src="https://checkout.stripe.com/checkout.js"></script>
          <%= hidden_field_tag 'stripeToken' %>
          <%= hidden_field_tag 'stripeEmail' %>  
          <button id="btn-buy" type="button" class="btn btn-success btn-lg btn-block"><span class="glyphicon glyphicon-heart"></span>   I want this!</button>

          <script>
          var handler = StripeCheckout.configure({
            key: '<%= Rails.configuration.stripe[:publishable_key] %>',
            token: function(token, arg) {
              document.getElementById("stripeToken").value = token.id;
              document.getElementById("stripeEmail").value = token.email;
              document.getElementById("chargeForm").submit();
            }
          });
           document.getElementById('btn-buy').addEventListener('click', function(e) {
            handler.open({
              name: 'OMG! <%= @pin.manufacturer %>',
              description: '<%= @pin.description %>',
              amount: 1000
          });
          e.preventDefault();
         })
        </script>
      <% end %>

app/controllers/charges_controller.rb

class ChargesController < ApplicationController

def create
  # Amount in cents
  @amount = 500

  customer = Stripe::Customer.create(
    :email => params[:stripeEmail],
    :card  => params[:stripeToken]
  )

  charge = Stripe::Charge.create(
    :customer    => customer.id,
    :amount      => @amount,
    :description => 'Rails Stripe customer',
    :currency    => 'usd'
  )

    rescue Stripe::CardError => e
      flash[:error] = e.message
      redirect_to charges_path
   end

end

Answer 1

你的JavaScript代码读取

document.getElementById("chargeForm").submit();

当你的表单名称为 chargesForm 时

<%= form_tag charges_path, id: 'chargesForm' do %>

Answer 2

我可以帮您翻译。这段内容是关于编程的。当我在一个页面中有很多表单进行删除操作时，我遇到了类似的问题。后来我发现，引号（单引号或双引号）必须出现在某个位置，才能解决这个错误。请注意保留HTML标签。

  document.getElementById("whatever id keep quotes ").submit();

并确保它与表单ID匹配。

例如：

  document.getElementById("'delform'.$key ").submit();

  <form id="delform.$key" action="" ></form>
