## Ready event

`element.on(event: 'ready', handler: function)`

Triggered when the `Element` is fully rendered and methods on the instance, like `element.focus()` and `element.update()`, can be called.

- `event`
  The name of the event.
In this case, `ready`.

- `handler`
  `handler(event) => void` is a **callback function** that you provide that will be called when the event is fired.

After it's called, it passes an event object with the following properties:
    - `elementType`
      The type of element the event is fired from.
    - `availablePaymentMethods (deprecated)`
      _This field has been deprecated in favor of the `paymentMethods` field on the [`availablepaymentmethodschange`](https://docs.stripe.com/js/elements_object/express_checkout_element_availablepaymentmethodschange_event.md) event, which also fires when available payment methods change after load._

This field is **only** present on the `expressCheckout` Element. Describes which buttons render in the Element. Returns undefined if no buttons will render.
      - `link`
      - `applePay`
      - `googlePay`
      - `paypal`
      - `amazonPay`
      - `klarna`
