Private debounceFormSubmitTimer

Private debounce

• debounce(event): false

  Debounce double-clicks

  If the click quickly succeeds a previous click then nothing will happen. This stops people accidentally causing multiple form submissions by double clicking buttons.

  Parameters

  • event: MouseEvent

    Mouse click event

  Returns false

  Returns undefined, or false when debounced

Private handleKeyDown

• handleKeyDown(event): void
• Private

  Trigger a click event when the space key is pressed

  Some screen readers tell users they can use the space bar to activate things with the 'button' role, so we need to match the functionality of native HTML buttons.

  Parameters

  • event: KeyboardEvent

    Keydown event
