条纹元素：如何在客户端验证卡片元素不是空白？

编程问答 2022-05-29

问题描述

Stripe 建议使用 change 事件对 card 元素进行客户端验证：

cardElement.on('change',function(event) {
  if (event.complete) {
    // enable payment button
  } else if (event.error) {
    // show validation to customer
  }
});

但是，如果用户从不编辑/更改卡片元素，则这种方法无法确定卡片元素是否无效。我总是可以尝试使用 confirmCardPayment 提交付款，但这效率低下 - 这种验证应该可以在客户端进行。

我可以通过将付款表单默认为错误状态来解决此问题，然后在用户第一次更改卡时解决（或不解决）错误状态。但是，这并不方便，因为它需要我将应用程序代码中的“您的卡号不完整”错误消息国际化，而不是依赖 Stripe。

理想情况下，我可以同步检查卡片元素是否有错误，或者至少同步触发更改事件，但这些似乎都不可能。

解决方法

Stripe.js 根据 Element 的状态将多个类应用于每个 Stripe Element 的容器：

  • StripeElement--focus
  • StripeElement--invalid
  • StripeElement--webkit-autofill
  • StripeElement--empty
  • const cardElementContainer = document.querySelector('#card-element'); let cardElementEmpty = cardElementContainer.classList.contains('StripeElement--empty'); // Do things based on cardElementEmpty being true or false （仅限 Chrome 和 Safari）

您可以在 Stripe's documentation 中阅读有关这些类的更多信息，包括如何自定义它们。

while (true)
{
    Console.Write("My Command : ");
    string input = Console.ReadLine();
    if (input.ToUpper() == @"SET /P")
        Console.WriteLine("command correct : " + input);
    else
        Console.WriteLine("command wrong : " + input);
