User activity is used to determine when controls should show/hide. It's
relatively simple when it comes to mouse events, because any mouse event
should show the controls. So we capture mouse events that bubble up to the
player and report activity when that happens.
With touch events it isn't as easy. We can't rely on touch events at the
player level, because a tap (touchstart + touchend) on the video itself on
mobile devices is meant to turn controls off (and on). User activity is
checked asynchronously, so what could happen is a tap event on the video
turns the controls off, then the touchend event bubbles up to the player,
which if it reported user activity, would turn the controls right back on.
(We also don't want to completely block touch events from bubbling up)
Also a touchmove, touch+hold, and anything other than a tap is not supposed
to turn the controls back on on a mobile device.
Here we're setting the default component behavior to report user activity
whenever touch events happen, and this can be turned off by components that
want touch events to act differently.Defined in https://github.com/videojs/video.js/blob/master/src/js/component.js line number: 1174[back to top]static extend( props ) (deprecated)Sets up the constructor using the supplied init method

    myComponent.on('eventType', myFunc);The context of myFunc will be myComponent unless previously bound.
Alternatively, you can add a listener to another element or component.
    myComponent.on(otherElement, 'eventName', myFunc);
    myComponent.on(otherComponent, 'eventName', myFunc);The benefit of using this over VjsEvents.on(otherElement, 'eventName', myFunc)
and otherComponent.on('eventName', myFunc) is that this way the listeners
will be automatically cleaned up when either component is disposed.
It will also bind myComponent as the context of myFunc.
NOTE: When using this on elements in the page other than window
and document (both permanent), if you remove the element from the DOM
you need to call myComponent.trigger(el, 'dispose') on it to clean up
references to it and allow the browser to garbage collect it.ParametersnameTypeRequiredDescriptionfirstString|ComponentyesThe event type or other componentsecondfunction|StringyesThe event handler or event typethirdfunctionyesThe event handlerDefined in https://github.com/videojs/video.js/blob/master/src/js/component.js line number: 605[back to top]one( first, second, [third] )Add an event listener to be triggered only once and then removed
