我正在尝试在Stripe Checkout UI中实现一个可变价格,该价格将由Pusher更新。
首先,我将Pusher消息分配给名为 price 的全局变量。
<script type="text/javascript">
var pusher = new Pusher('7a5433c6fc39502a4a02');
var channel = pusher.subscribe('the_channel');
var price
channel.bind('the_event', function(data) {
price = data.message
});
</script>
如果我将价格分配给数据金额,我会面临两个问题:
1-在流程方面,默认情况下该字段为空,仅在Pusher发送消息时填充。
2-语法方面,当推送时,变量当前甚至不呈现消息
<%= form_tag charges_path, class: 'stripeform' do %>
<script src="https://checkout.stripe.com/checkout.js" class="stripe-button"
data-key="<%= Rails.configuration.stripe[:publishable_key] %>"
data-amount= <%= @price %>
</script>
<% end %>
怎么办?

我建议您在Rails控制器中为@price
设置默认值。
然后按照Stripe上的文档,你可以使用这样的东西来创建一个价格可变的按钮。请记住,正如条纹文档所说,您仍然需要以正确的金额创建费用
<script src="https://checkout.stripe.com/checkout.js"></script>
<div id="price-display">$<%= @price %></div>
<button id="customButton">Purchase</button>
<script>
var price = parseInt("<%= @price %>");
var pusher = new Pusher('7a5433c6fc39502a4a02');
var channel = pusher.subscribe('the_channel');
channel.bind('the_event', function(data) {
price = parseInt(data.message);
document.getElementById('price-display').innerHTML = "$" + data.message;
});
var handler = StripeCheckout.configure({
key: "<%= Rails.configuration.stripe[:publishable_key] %>",
image: '/square-image.png',
token: function(token) {
// Use the token to create the charge with a server-side script.
// You can access the token ID with `token.id`
}
});
$('#customButton').on('click', function(e) {
// Open Checkout with further options
handler.open({
name: 'Demo Site',
description: '2 widgets',
amount: price
});
e.preventDefault();
});
// Close Checkout on page navigation
$(window).on('popstate', function() {
handler.close();
});
</script>
