Validate Stripe Elements without calling `createToken` #283

Sorry if this is the wrong place for this but IRC and chat support was proving difficult -- I figured I'd hit the right people through GitHub.

I'm struggling to work out how one can trigger the Stripe Elements client-side validation without calling createToken i.e.

Given this form:

And this handler:

handleSubmit = async (e) => {
    const firstNameError = validateFirstName(this.props.firstName);
    const lastNameError = validateLastName(this.props.lastName);
    const stripeElementsErrors = this.props.stripe.validateElements(); // Does this method exist?
    if (!firstNameError && !lastNameError && !stripeElementErrors.length) {
        const { token, error } = await this.props.stripe.createToken({
             name: `${firstName} ${lastName}`,
        // ...

The key is I need to be able to render validation errors on both my non-stripe fields (firstName and lastName) as well as my Stripe fields before attempting to create the token; I can't call createToken if my billing fields are invalid.

Hi @richardscarrott, there isn't a way to do this either with react-stripe-elements or Stripe.js itself. The recommended pattern here is to:

  1. Assume that the user's input starts in an incomplete state and block form submission.
  2. Use an element.on('change', (event) => …) event handler to update your form's state.
  3. If there are errors in event.errors, display them and continue to block form submission.
  4. When you receive a change event with event.complete == true, allow form submission to proceed.

This will require tracking the Elements validation state inside your form component. Hope that clears things up! If you have any specific questions about a form you're building Stripe Support is the best avenue for support:

This repository's issue tracker is for the development of the react-stripe-elements library itself rather than Stripe.js questions.
