I'm building a simple website that will process payments with Stripe. I'm using Bootstrap for my styling. When I use Stripe Elements to insert the payment fields, they aren't styled with Bootstrap. How can I apply Bootstrap's styling to the Elements payment fields?

Alright, so I had to figure this out, because I was using Stripe.js v2, and the security vulnerability was explained to me by Stripe tech support, so I felt obligated to switch to Stripe.js v3 "Elements". What they said was that any javascript on the same page as your credit card form elements could obtain the values of the sensitive credit card data. I suppose this could happen if a person was pulling in external scripts ... and I suppose it must have happened, or they wouldn't care about it. Anyway, this is how I got my Stripe.js v3 elements working with Bootstrap 4 input groups. It's a full working example, you'd just need to change out the public key.

I tested only in Firefox, Chrome, and Chrome on Android. Seems to work fine. Let me know if you experience any issues.

This Vue.js example could benefit from some work, but may help get you started.
回答2:
After digging around the docs a bit more, I found that https://stripe.com/docs/stripe.js#the-element-container says "You should style the container you mount an Element to as if it were an on your page."
By adding Bootstrap's form-control class to the <div> I'm mounting the Element in, the field looks almost like any other Bootstrap-styled input field:
<div id="card-element" class="form-control"></div>
For some reason, the height of the field doesn't quite match, but through trial and error, I got it with:
var stripe = Stripe('your_key');
var elements = stripe.elements();
var card = elements.create('card', { style:
{
base: {
lineHeight: '1.429'
}
}
});
card.mount('#card-element');
回答3:
This is all that was required for us using
<div class="form-group">
<label for="card-element">Credit or debit card</label>
<div id="card-element" class="form-control" style='height: 2.4em; padding-top: .7em;'>
<!-- A Stripe Element will be inserted here. -->
</div>
</div>
回答4:
Adding another Answer since I felt the simplest one on here was slightly incomplete. Added the error display and the JavaScript used to send the token to the back-end in case you want to do that.
This HTML (which is right from their default docs with Bootstrap 4 elements added)
<form action="/charge" method="post" id="payment-form">
<div class="form-group">
<label for="card-element">
Credit or debit card
</label>
<div id="card-element" class="form-control">
<!-- A Stripe Element will be inserted here. -->
</div>
<!-- Used to display Element errors. -->
<div id="card-errors" role="alert"></div>
</div>
<button>Submit Payment</button>
</form>
And This is the JavaScript (again right from their default docs but I use jQuery here but you dont have to)
<script src="https://js.stripe.com/v3/"></script>
<script>
(function ($) {
// Set your publishable key: remember to change this to your live publishable key in production
// See your keys here: https://dashboard.stripe.com/account/apikeys
var stripe = Stripe('yourPublishableKeyHere');
var elements = stripe.elements();
// Custom styling can be passed to options when creating an Element.
var style = {
base: {
// Add your base input styles here. For example:
fontSize: '16px',
color: '#32325d',
},
};
// 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');
// Create a token or display an error when the form is submitted.
var form = document.getElementById('payment-form');
form.addEventListener('submit', function(event) {
event.preventDefault();
stripe.createToken(card).then(function(result) {
if (result.error) {
// Inform the customer that 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);
}
});
});
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();
}
})(jQuery);
