Uncaught TypeError: Cannot read property 'submit' of null for stripe payment

Question

我正在将条纹支付集成到我的应用程序中。我将 Stripe 默认 "Pay with Card" 按钮换成了我自定义的按钮。这样做之后，测试模式成功弹出，我可以输入测试凭据。但是，当我提交测试付款并获得批准时，它只是停留在同一个 pin 页面上，而不是转到我为其创建的收费页面。

注意：在我用新的自定义按钮替换默认的条纹支付按钮之前，该应用程序可以很好地从条带支付过渡到收费 create.html.erb 页面。

此外，在查看开发者工具时，我确实注意到在我提交测试付款时它会显示：

Uncaught TypeError: Cannot read property 'submit' of null

我认为这是指我在下面提交收费表格的代码。

有人以前遇到过这个问题或知道我可以解决这个问题吗？非常感谢！

Answer 1

您的 Javascript 代码为

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

而您的表单名称是 chargesForm

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

Answer 2

当我在一个页面中有很多表单用于 table 中的删除操作时，我遇到了类似的问题。当我发现引号（单引号或双引号）必须出现在

  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>
