Advanced Customization with Elements: Programmatic Control and Validation

While Stripe Elements provide a visually appealing and secure way to collect payment details out-of-the-box, you often need to go beyond basic styling to create a truly tailored user experience. This involves programmatic control over Element behavior and implementing custom validation logic to ensure data integrity and guide your users effectively.

Programmatic control allows you to dynamically update or interact with your Stripe Elements based on user actions or application state. This can include enabling/disabling elements, clearing fields, or even pre-filling information.

A key aspect of programmatic control is accessing the Element instance itself. When you create an Element using stripe.elements().create(), you get back an object representing that Element. This object has methods you can call to manage its state.

Beyond enabling/disabling and clearing, you can also update other properties of an Element dynamically. For instance, you might want to pre-fill the cardholder name or update the placeholder text based on the selected payment method.

Custom validation is crucial for providing immediate feedback to your users and preventing them from submitting incomplete or incorrect payment information. Stripe Elements have built-in validation, but you can augment this with your own logic.
