:submit vráti: Array
Vyberie všetky input elementy typu submit.
:submit selektor sa zvyčajne vzťahuje na button alebo input elementy. Všimnite si, že niektoré prehliadače implicitne traktujú <button> element ako type="default", zatiaľ čo iné (napr. Internet Explorer) nie.
Priklady:
Vyhľadá všetky submit elementy, ktoré sú potomkami TD elementu.
