我正在尝试使用Python Flask和Stripe实施电子商务网站付款结帐页面。我成功设置了Stripe;但是，我现在正在尝试添加一个＆＃34;促销代码＆＃34;功能，用户可以在其中键入促销代码，单击＆＃34;应用促销代码＆＃34;按钮，post方法将发送到我的后端，以便验证促销代码。
不幸的是，我目前在HTML中运行此脚本：
<script src="https://checkout.stripe.com/checkout.js" class = "stripe-button" style = ""
data-key="{{ key }}"
data-description=""
data-amount="{{ amount }}"
data-locale="auto">
</script>
<script>
document.getElementsByClassName("stripe-button-el")[0].style.display = 'none';
</script>
这是在每次检测到POST请求时运行Stripe checkout脚本。这是有问题的，因为我的＆＃34;应用促销代码＆＃34;按钮还会生成一个帖子请求：
<div class="form-group">
<div class="col-md-12" style = "margin-bottom: 10px">
<input type="code" name="code" id="code" class="form-control" placeholder="Enter Code Here" style = "margin: 0 0 10px 0; border: solid 0.5px #0b3c5d; border-radius: 6px">
</div>
</div>
我的问题是：每次检测到发布请求时，不是运行脚本src，而是仅当＆＃34;确认订单＆＃34;时才能运行脚本src。单击按钮而不是＆＃34;应用促销代码＆＃34;单击按钮？在Python中检测request.form [＆＃39; submit＆＃39;]值的常用方法不起作用，因为Stripe脚本侦听post请求并且不关心post请求的值。这是我的后端：
@app.route('/charge', methods=['GET', 'POST'])
def charge():
if request.method == 'POST':
session.modified = True
if request.form.get('code') and not request.form['code'] == 'SAVE10MORE':
print('WRONG!')
customer = stripe.Customer.create(
email = session['user'],
source = request.form['stripeToken']
)
charge = stripe.Charge.create(
customer = customer.id,
amount = int(100 * (session['subtotal'] + session['tax'])),
currency = 'usd',
description = 'Payment'
)
orders = mongo.db.orders
has_ordered = orders.find_one({'_id': session['user']})
if has_ordered:
orders.update({'_id': session['user']},
{'$set':
{'name': request.form['name'],
'dorm': request.form['dorm']}})
else:
orders.insert({'_id': session['user'],
'name': request.form['name'],
'dorm': request.form['dorm']})
for key, value in (session['customer']).iteritems():
has_ordered = orders.find_one({'_id': session['user'], str(key): {'$exists': True}})
total = int(value)
if has_ordered:
total += int(has_ordered[key])
orders.update({'_id': session['user']},
{'$set':
{key: total}})
content = render_template('message.html', ordered = True)
send_mail('Your Order Summary', content, session['user'], True)
session['customer'] = {}
return redirect(url_for('index'))
else:
try:
if g.user:
return render_template('charge.html',
key = stripe_keys['publishable_key'],
amount = int(100 * (session['subtotal'] + session['tax'])),
tax = session['tax'],
subtotal = session['subtotal'],
months = 2 * deliveries_remaining())
except KeyError:
return redirect(url_for('shop'))
return redirect(url_for('login'))
请告诉我如何在点击某个按钮时停止脚本src的运行！提前致谢！这将非常有用。

您可能需要使用Checkout的"custom integration"，它允许您从JavaScript代码触发弹出窗口。然后，您可以将弹出窗口的开头绑定到“确认订单”按钮的单击事件处理程序。
