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.

Defined in https://github.com/videojs/video.js/blob/master/src/js/component.js line number: 998

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
}
]
});
Defined in https://github.com/videojs/video.js/blob/master/src/js/component.js line number: 455
name()
Get the component's name. The name is often used to reference the component.
var name = myComponent.name();
Defined in https://github.com/videojs/video.js/blob/master/src/js/component.js line number: 269
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
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
name | Type | Required | Description |
---|---|---|---|
first | String|Component | yes | The event type or other component |
second | function|String | yes | The event handler or event type |
third | function | yes | The event handler |
Defined in https://github.com/videojs/video.js/blob/master/src/js/component.js line number: 605
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);
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 function for other component |
