Card Form Submit Button Component

<primer-card-form-submit>

The Card Form Submit Button component provides a standardized submit button specifically designed for card payment forms. It includes localization support and consistent styling. Under the hood, it wraps a primer-button component to provide additional payment form-specific functionality.

Usage

The Card Form Submit Button component is designed to be used within a primer-card-form container:

<primer-card-form>
  <!-- Card form inputs -->
  <primer-card-form-submit></primer-card-form-submit>
</primer-card-form>

Properties

Property	Attribute	Type	Default	Description
buttonText	buttonText	string	Localized "Pay" text	The text displayed on the button. If not explicitly set, falls back to a localized version of "Pay" based on the application's language settings
variant	variant	string	"primary"	Button variant/style ("primary", etc.)
disabled	disabled	boolean	false	Whether the button is disabled

Events

Event Name	Description	Event Detail
primer:card-submit	Fired when the button is clicked	{ source: 'primer-card-form-submit' }

Internal vs. Triggerable Events

This event is dispatched internally by the submit button component. For programmatically triggering card form submission from external code, see the triggerable primer:card-submit event documented in the Card Form Component.

Features

• Localization Support: Button text is automatically localized based on the application's language
• Consistent Styling: Ensures a consistent look and feel across all checkout forms
• Customization Options: Text and button variant can be customized
• Automatic Integration: Works seamlessly with the card form's submission logic
• Click Handling: Prevents default form submission to allow for custom validation and submission flow

Component Flow

The submit button dispatches the primer:card-submit event when clicked, which the card form captures and processes.

DOM Structure

This component uses display: contents which means it doesn't create a new box in the DOM layout. Instead, it renders the inner primer-button directly within the parent container. The rendered DOM looks like:

<primer-button buttonType="submit" variant="primary|secondary|etc" data-submit>
  Payment Text
</primer-button>

Examples

<primer-card-form>
  <!-- Card form inputs -->
  <primer-card-form-submit></primer-card-form-submit>
</primer-card-form>

<primer-card-form>
  <!-- Card form inputs -->
  <primer-card-form-submit buttonText="Complete Payment" variant="secondary">
  </primer-card-form-submit>
</primer-card-form>

<primer-card-form>
  <!-- Card form inputs -->
  <primer-card-form-submit disabled></primer-card-form-submit>
</primer-card-form>

Key Considerations

Default Behavior

• The Card Form Submit Button is automatically included in the default card form layout
• When using a custom layout with the card-form-content slot, you'll need to add this component manually

Submission Options

• You can use either this component or a standard HTML button with type="submit" or the data-submit attribute

Text Localization

• The button text is automatically localized by default, falling back to a localized version of "Pay" if not explicitly set
• Setting the buttonText property to an empty string will revert to using the localized default text

Implementation Detail

• The component adds a data-submit attribute to the internal button, which can be used for styling or selection
