n_clicks	Numeric. An integer that represents the number of times that this element has been clicked on.
n_clicks_timestamp	Numeric. An integer that represents the time (in ms since 1970) at which n_clicks changed. This can be used to tell which button was changed most recently.

autoFocus	A value equal to: 'autofocus', 'autofocus', 'autofocus' | logical. The element should be automatically focused after the page loaded.

form	Character. Indicates the form that is the owner of the element.
formAction	Character. Indicates the action of the element, overriding the action defined in the <form>.
