【中文标题】条纹支付示例未显示【英文标题】:Stripe payment example is not displaying 【发布时间】:2017-08-18 21:21:51 【问题描述】:

我正在尝试创建一个使用 Stripe 支付的非常简单的示例。

这是我的代码:

// Create a Stripe client
var stripe = Stripe('pk_test_XSHE4IYLLy9qCPe7lW7pK4ZE');

// Create an instance of Elements
var elements = stripe.elements();

// Custom styling can be passed to options when creating an Element.
// (Note that this demo uses a wider set of styles than the guide below.)
var style = 
base: 
  color: '#32325d',
  lineHeight: '24px',
  fontFamily: '"Helvetica Neue", Helvetica, sans-serif',
  fontSmoothing: 'antialiased',
  fontSize: '16px',
  '::placeholder': 
    color: '#aab7c4'
  
,
invalid: 
  color: '#fa755a',
  iconColor: '#fa755a'

;

// Create an instance of the card Element
var card = elements.create('card', style: style);

// Add an instance of the card Element into the `card-element` <div>
card.mount('#card-element');

// Handle real-time validation errors from the card Element.
card.addEventListener('change', function(event) 
var displayError = document.getElementById('card-errors');
if (event.error) 
  displayError.textContent = event.error.message;
 else 
  displayError.textContent = '';

);

// Handle form submission
var form = document.getElementById('payment-form');
form.addEventListener('submit', function(event) 
event.preventDefault();

stripe.createToken(card).then(function(result) 
  if (result.error) 
    // Inform the user if there was an error
    var errorElement = document.getElementById('card-errors');
    errorElement.textContent = result.error.message;
   else 
    // Send the token to your server
    stripeTokenHandler(result.token);
  
);
);
.StripeElement 
background-color: white;
padding: 8px 12px;
border-radius: 4px;
border: 1px solid transparent;
box-shadow: 0 1px 3px 0 #e6ebf1;
-webkit-transition: box-shadow 150ms ease;
transition: box-shadow 150ms ease;


.StripeElement--focus 
box-shadow: 0 1px 3px 0 #cfd7df;

    <form action="/charge" method="post" id="payment-form">
      <div class="form-row">
        <label for="card-element">
          Credit or debit card
        </label>
        <div id="card-element">
          <!-- a Stripe Element will be inserted here. -->
        </div>

        <!-- Used to display form errors -->
        <div id="card-errors"></div>
      </div>

      <button>Submit Payment</button>
    </form>

  </body>
</html>

我按照Stripe的例子。

这是我从 javascript 控制台得到的错误:

Uncaught Error: The selector you specified (#card-element) applies to no DOM elements that are currently on the page.
Make sure the element exists on the page before calling mount().
     at new t (js.stripe.com/:1)
     at t.value (js.stripe.com/:1)

基于错误,我认为 Stripe JavaScript 找不到任何 #card-element,但它就在那里。

这可能是一个愚蠢的问题,但这是我第一次使用 Stripe,所以如果有人可以帮助我,那就太好了。非常感谢。

【问题讨论】:

有什么地方特别卡住了吗?从您的代码来看,您似乎仍然需要定义 stripeTokenHandler(result.token); 引用的 stripeTokenHandler --- 这里有一个示例 stripe.com/docs/elements#submit-token @duck 我只是完全按照他们的例子。我编辑了我的帖子显示你可以看到错误。非常感谢 hmm,如果您收到“无 DOM 元素”错误,是的,看起来您在页面上存在 #card-element 之前正在加载 JS。看看这里的一个例子jsbin.com/dukecivela/edit?html,output @duck 谢谢。现在可以了。你是对的。但我可以在页面末尾包含我的 js 库,但我从未在页面末尾编写过我的 js 脚本。可以吗? 当然,@trinhdh,您可以在最后加载您的 JS,或者您可以将您的代码包装在 $(document).ready (JQuery) 或`document.addEventListener("DOMContentLoaded", function(event) ); 这样它不会在内容加载之前执行. developer.mozilla.org/en-US/docs/Web/Events/DOMContentLoaded 【参考方案1】:

不要在头部添加脚本,而是在关闭正文之前添加它。

<html lang= "en">
    <head>
        <meta charset="utf-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <title>test</title>
    </head>
    <body>
        <form action="/charge" method="post" id="payment-form">
            <div class="form-row">
                <label for="card-element">
                    Credit or debit card
                </label>
                <div id="card-element">
                <!-- a Stripe Element will be inserted here. -->
                </div>
                <!-- Used to display form errors -->
                <div id="card-errors"></div>
            </div>
            <button>Submit Payment</button>
        </form>
        <script src="https://js.stripe.com/v3/"></script>
    </body>
</html>

将脚本放在底部可确保在执行脚本之前渲染 DOM,这样就可以解决问题!

【讨论】:

将它移到正文后,我遇到了 Stripe 没有为我的 JS 代码的其余部分定义【参考方案2】:

把你的脚本放在 html 之后,

 <form></form>
 //after your stripe form put stripe script 
 <script></script>

如下

【参考方案3】:

对于遇到同样问题的其他人 - Stripe 文档中的代码 sn-p 不完整。因此,实际上可能需要上述建议的修复以确保正确的操作顺序,但除非您定义 stripeTokenHandler 方法,否则整个事情将无法正常工作。

Stripe 的文档将方法(页面下方)定义为:

function stripeTokenHandler(token) 
  // Insert the token ID into the form so it gets submitted to the server
  var form = document.getElementById('payment-form');
  var hiddenInput = document.createElement('input');
  hiddenInput.setAttribute('type', 'hidden');
  hiddenInput.setAttribute('name', 'stripeToken');
  hiddenInput.setAttribute('value', token.id);
  form.appendChild(hiddenInput);

  // Submit the form
  form.submit();

【讨论】:

var form = document.getElementById('payment-form');正在返回“未定义” 您的表单标签是什么样的?在 Stripe 文档(和 OP 的代码)中,它是:
是的。
【参考方案4】:

Stripe.js 在 iF​​rame 中呈现信用卡号、到期日、CVC 的输入。您无法使用 JavaScript 创建或获取它们。但是,您可以根据需要为容器设置样式,这将使您能够与网站的 UI 非常接近 - Bootstrap、MDC-Web 或其他。

如果您的元素未显示,请尝试以下操作开始。

<div class="stripe-custom-element">
    <label for="stripe-card">Card Number</label>
    <div class="" id="stripe-card"></div>
</div>
<div class="stripe-custom-element">
    <label for="stripe-exp">Expiration</label>
    <div class="" id="stripe-exp"></div>
</div>
<div class="stripe-custom-element">
    <label for="stripe-cvc">CVC</label>
    <div class="" id="stripe-cvc"></div>
</div>

var cardNumberElement = doc.getElementById("stripe-card");
var cardExpiryElement = doc.getElementById("stripe-exp");
var cardCvcElement = doc.getElementById("stripe-cvc");

var cardNumber = elements.create('cardNumber', );
var cardExpiry = elements.create('cardExpiry', );
var cardCvc = elements.create('cardCvc', );

cardNumber.mount(cardNumberElement);
cardExpiry.mount(cardExpiryElement);
cardCvc.mount(cardCvcElement);        

registerElements([cardNumber, cardExpiry, cardCvc]);

【参考方案5】:

我可能迟到了,但这对我有用,请确保在条带脚本下方添加charge.js 脚本,另外,在结束正文标记之前添加它们

<html lang= "en">
    <head>
      
    
      <link rel="stylesheet" href="style.css"/>
        <meta charset="utf-8">

    </head>

    <body>
        <form action="/charge" method="post" id="payment-form">
            <div class="form-row">

                <div id="card-element">
