enableTouchActivity()
Report user touch activity when touch events occur
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.

not the actual computed width/height.
Parameters

[back to top]
initChildren()
Add and initialize default child components from options
// when an instance of MyComponent is created, all children in options
// will be added to the instance by their name strings and options
MyComponent.prototype.options_ = {
children: [
'myChildComponent'
],
myChildComponent: {
myChildOption: true
}
};
// Or when creating the component
var myComp = new MyComponent(player, {
children: [
'myChildComponent'
],
myChildComponent: {
myChildOption: true
}
});
The children option can also be an array of
child options objects (that also include a 'name' key).
This can be used if you have two child components of the
same type that need different options.
var myComp = new MyComponent(player, {
children: [
'button',
{
name: 'button',
someOtherOption: true
},
{
name: 'button',
someOtherOption: false
}
]
});

var name = myComponent.name();
Defined in https://github.com/videojs/video.js/blob/master/src/js/component.js line number: 269
[back to top]
off( first, second, [third] )
Remove an event listener from this component's element
myComponent.off('eventType', myFunc);
If myFunc is excluded, ALL listeners for the event type will be removed.
If eventType is excluded, ALL listeners will be removed from the component.
Alternatively you can use off to remove listeners that were added to other
elements or components using myComponent.on(otherComponent....
In this case both the event type and listener function are REQUIRED.
myComponent.off(otherElement, 'eventType', myFunc);
myComponent.off(otherComponent, 'eventType', myFunc);
Parameters
name
Type
Required
Description
first
String|Component
yes
The event type or other component
second
function|String
yes
The listener function or event type
third
function
no
The listener for other component
Defined in https://github.com/videojs/video.js/blob/master/src/js/component.js line number: 680
[back to top]
on( first, second, third )
Add an event listener to this component's element
var myFunc = function(){
var myComponent = this;
// Do something when the event is fired
};
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.
Parameters

Required
Description
first
String|Component
yes
The event type or other component

The event handler or event type

[back to top]
one( first, second, [third] )
Add an event listener to be triggered only once and then removed
myComponent.one('eventName', myFunc);
Alternatively you can add a listener to another element or component
that will be triggered only once.
myComponent.one(otherElement, 'eventName', myFunc);
myComponent.one(otherComponent, 'eventName', myFunc);
