There is a phrase in Help that refers to the timeline that on contains the button in an event-handling function action that is attached to the button this . Refers to the timeline of this the movie clip itself, in the Onclipevent () event handler action that is attached to the movie clip. "

if

_root.button.onpress=function () {
This
}
