Create the component's DOM element

Finds a single DOM element matching selector within the component's contentEl or another custom context.

Finds a all DOM elements matching selector within the component's contentEl or another custom context.

Adds a child component inside this component

    myComponent.el();
    // -> 

    myComponent.children();
    // [empty array]

    var myButton = myComponent.addChild('MyButton');
    // -> 
myButton

    // -> myButton === myComponent.children()[0];

Pass in options for child constructors and options for children of the child

    var myButton = myComponent.addChild('MyButton', {
      text: 'Press Me',
      buttonChildExample: {
        buttonChildOption: true
      }
    });

Add a CSS class name to the component's element

Allows sub components to stack CSS class names

Get an array of all child components

    var kids = myComponent.children();

Clears an interval and removes the associated dispose listener

Clears a timeout and removes the associated dispose listener

Return the component's DOM element where children are inserted. Will either be the same as el() or a new element defined in createEl().

Set both width and height at the same time

Dispose of the component and all child components

Get the component's DOM element

    var domEl = myComponent.el();

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.

Sets up the constructor using the supplied init method or uses the init of the parent object

Returns a child component with the provided name

Returns a child component with the provided ID

Gets a component by name

Check if a component's element has a CSS class name

Get or set the height of the component (CSS values) Setting the video tag dimension values only works with values in pixels. Percent values will not work. Some percents can be used, but width()/height() will return the number + %, not the actual computed width/height.

Hide the component element if currently showing

Get the component's ID

    var id = myComponent.id();

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
        }
      ]
    });

Get the component's name. The name is often used to reference the component.

    var name = myComponent.name();

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);

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.

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);

Deep merge of options objects Whenever a property is an object on both options objects the two properties will be merged using mergeOptions.

    Parent.prototype.options_ = {
      optionSet: {
        'childOne': { 'foo': 'bar', 'asdf': 'fdsa' },
        'childTwo': {},
        'childThree': {}
      }
    }
    newOptions = {
      optionSet: {
        'childOne': { 'foo': 'baz', 'abc': '123' }
        'childTwo': null,
        'childFour': {}
      }
    }

    this.options(newOptions);

RESULT

    {
      optionSet: {
        'childOne': { 'foo': 'baz', 'asdf': 'fdsa', 'abc': '123' },
        'childTwo': null, // Disabled. Won't be initialized.
        'childThree': {},
        'childFour': {}
      }
    }

Return the component's player

Bind a listener to the component's ready state. Different from event listeners in that if the ready event has already happened it will trigger the function immediately.

Registers a component

Remove a child component from this component's list of children, and the child component's element from this component's element

Remove a CSS class name from the component's element

Creates an interval and sets up disposal automatically.

Creates timeout and sets up disposal automatically.

Show the component element if hidden

Add or remove a CSS class name from the component's element

Trigger an event on an element

    myComponent.trigger('eventName');
    myComponent.trigger({'type':'eventName'});
    myComponent.trigger('eventName', {data: 'some data'});
    myComponent.trigger({'type':'eventName'}, {data: 'some data'});

Trigger the ready listeners

Set or get the width of the component (CSS values) Setting the video tag dimension values only works with values in pixels. Percent values will not work. Some percents can be used, but width()/height() will return the number + %, not the actual computed width/height.
