book_pick_book_nojs_submit

book_pick_book_nojs_submit($form, FormStateInterface $form_state)

Form submission handler for node_form().

This handler is run when JavaScript is disabled. It triggers the form to rebuild so that the "Parent item" options are changed to reflect the newly selected book. When JavaScript is enabled, the submit button that triggers this handler is hidden, and the "Book" dropdown directly triggers the book_form_update() Ajax callback instead.
