@ckeditor/ckeditor5-ui/src/search/text/searchtextview

class
See source

A search component that allows filtering of an arbitrary view based on a search query specified by the user in a text field.

// This view must specify the `filter()` and `focus()` methods.
const filteredView = ...;

const searchView = new SearchTextView( locale, {
	searchFieldLabel: 'Search list items',
	filteredView
} );

view.render();

document.body.append( view.element );

Properties

  • readonly inherited

    bindTemplate : BindChain<this>

    See source

    Shorthand for bind, a binding interface pre–configured for the view instance.

    It provides to() and if() methods that initialize bindings with observable attributes and attach DOM listeners.

    class SampleView extends View {
	constructor( locale ) {
		super( locale );

		const bind = this.bindTemplate;

		// These observable attributes will control
		// the state of the view in DOM.
		this.set( {
			elementClass: 'foo',
		 	isEnabled: true
		 } );

		this.setTemplate( {
			tag: 'p',

			attributes: {
				// The class HTML attribute will follow elementClass
				// and isEnabled view attributes.
				class: [
					bind.to( 'elementClass' )
					bind.if( 'isEnabled', 'present-when-enabled' )
				]
			},

			on: {
				// The view will fire the "clicked" event upon clicking <p> in DOM.
				click: bind.to( 'clicked' )
			}
		} );
	}
}

  • readonly

    children : ViewCollection<View<HTMLElement>>

    See source

    The collection of children of the view.

    class SampleView extends View {
	constructor() {
		super();

		// A template instance the #element will be created from.
		this.setTemplate( {
			tag: 'p'

			// ...
		} );
	}
}

const view = new SampleView();

// Renders the #template.
view.render();

// Append the HTML element of the view to <body>.
document.body.appendChild( view.element );

  • inherited

    bind( bindProperty1, bindProperty2 ) → DualBindChain<K1, SearchTextView<TQueryFieldView>[ K1 ], K2, SearchTextView<TQueryFieldView>[ K2 ]>

    See source

    Binds observable properties to other objects implementing the Observable interface.

    Read more in the dedicated guide covering the topic of property bindings with some additional examples.

    Consider two objects: a button and an associated command (both Observable).

    A simple property binding could be as follows:

    button.bind( 'isEnabled' ).to( command, 'isEnabled' );

    or even shorter:

    button.bind( 'isEnabled' ).to( command );

    which works in the following way:

    • button.isEnabled instantly equals command.isEnabled,
    • whenever command.isEnabled changes, button.isEnabled will immediately reflect its value.

    Note: To release the binding, use unbind.

    You can also "rename" the property in the binding by specifying the new name in the to() chain:

    button.bind( 'isEnabled' ).to( command, 'isWorking' );

    It is possible to bind more than one property at a time to shorten the code:

    button.bind( 'isEnabled', 'value' ).to( command );

    which corresponds to:

    button.bind( 'isEnabled' ).to( command );
button.bind( 'value' ).to( command );

    The binding can include more than one observable, combining multiple data sources in a custom callback:

    button.bind( 'isEnabled' ).to( command, 'isEnabled', ui, 'isVisible',
	( isCommandEnabled, isUIVisible ) => isCommandEnabled && isUIVisible );

    Using a custom callback allows processing the value before passing it to the target property:

    button.bind( 'isEnabled' ).to( command, 'value', value => value === 'heading1' );

    It is also possible to bind to the same property in an array of observables. To bind a button to multiple commands (also Observables) so that each and every one of them must be enabled for the button to become enabled, use the following code:

    button.bind( 'isEnabled' ).toMany( [ commandA, commandB, commandC ], 'isEnabled',
	( isAEnabled, isBEnabled, isCEnabled ) => isAEnabled && isBEnabled && isCEnabled );

    Type parameters

    K1
    K2

    Parameters

    bindProperty1 : K1

    Observable property that will be bound to other observable(s).

    bindProperty2 : K2

    Observable property that will be bound to other observable(s).

    Returns

    DualBindChain<K1, SearchTextView<TQueryFieldView>[ K1 ], K2, SearchTextView<TQueryFieldView>[ K2 ]>

    The bind chain with the to() and toMany() methods.

    createCollection( [ views ] ) → ViewCollection<T>

    See source

    Creates a new collection of views, which can be used as children of this view.

    class SampleView extends View {
	constructor( locale ) {
		super( locale );

		const child = new ChildView( locale );
		this.items = this.createCollection( [ child ] );
 *
		this.setTemplate( {
			tag: 'p',

			// `items` collection will render here.
			children: this.items
		} );
	}
}

const view = new SampleView( locale );
view.render();

// It will append <p><child#element></p> to the <body>.
document.body.appendChild( view.element );

    Type parameters

    T : extends [object Object] = default

    Parameters

    [ views ] : Iterable<T>

    Initial views of the collection.

    Returns

    ViewCollection<T>

    A new collection of view instances.

  • inherited

    decorate( methodName ) → void

    See source

    Turns the given methods of this object into event-based ones. This means that the new method will fire an event (named after the method) and the original action will be plugged as a listener to that event.

    Read more in the dedicated guide covering the topic of decorating methods with some additional examples.

    Decorating the method does not change its behavior (it only adds an event), but it allows to modify it later on by listening to the method's event.

    For example, to cancel the method execution the event can be stopped:

    class Foo extends ObservableMixin() {
	constructor() {
		super();
		this.decorate( 'method' );
	}

	method() {
		console.log( 'called!' );
	}
}

const foo = new Foo();
foo.on( 'method', ( evt ) => {
	evt.stop();
}, { priority: 'high' } );

foo.method(); // Nothing is logged.

    Note: The high priority listener has been used to execute this particular callback before the one which calls the original method (which uses the "normal" priority).

    It is also possible to change the returned value:

    foo.on( 'method', ( evt ) => {
	evt.return = 'Foo!';
} );

foo.method(); // -> 'Foo'

    Finally, it is possible to access and modify the arguments the method is called with:

    method( a, b ) {
	console.log( `${ a }, ${ b }`  );
}

// ...

foo.on( 'method', ( evt, args ) => {
	args[ 0 ] = 3;

	console.log( args[ 1 ] ); // -> 2
}, { priority: 'high' } );

foo.method( 1, 2 ); // -> '3, 2'

    Parameters

    methodName : 'off' | 'search' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'element' | 'template' | 'focus' | 'reset' | 'children' | 'isRendered' | 'locale' | 't' | 'viewUid' | 'bindTemplate' | 'createCollection' | 'registerChild' | 'deregisterChild' | 'setTemplate' | 'extendTemplate' | 'render' | 'destroy' | 'focusCycler' | 'focusTracker' | 'isEnabled' | 'keystrokes' | 'resultsView' | 'filteredView' | 'infoView' | 'queryView' | 'resultsCount' | 'totalItemsCount' | 'focusableChildren'

    Name of the method to decorate.

    Returns

    delegate( events ) → EmitterMixinDelegateChain

    See source

    Delegates selected events to another Emitter. For instance:

    emitterA.delegate( 'eventX' ).to( emitterB );
emitterA.delegate( 'eventX', 'eventY' ).to( emitterC );

    then eventX is delegated (fired by) emitterB and emitterC along with data:

    emitterA.fire( 'eventX', data );

    and eventY is delegated (fired by) emitterC along with data:

    emitterA.fire( 'eventY', data );

    Parameters

    events : Array<string>

    Event names that will be delegated to another emitter.

    Returns

    EmitterMixinDelegateChain

  • inherited

    deregisterChild( children ) → void

    See source

    Parameters

    children : View<HTMLElement> | Iterable<View<HTMLElement>>

    Child views to be removed.

    Returns

    void

    Related:

  • inherited

    destroy() → void

    See source

    Recursively destroys the view instance and child views added by registerChild and residing in collections created by the createCollection.

    Destruction disables all event listeners:

    • created on the view, e.g. view.on( 'event', () => {} ),
    • defined in the template for DOM events.

    Returns

    void

  • inherited

    extendTemplate( definition ) → void

    See source

    Extends the template of the view with with given definition.

    A shorthand for:

    Template.extend( view.template, definition );

    Note: Is requires the template to be already set. See setTemplate.

    Parameters

    definition : Partial<TemplateDefinition>

    Definition which extends the template.

    Returns

    void

  • inherited

    fire( eventOrInfo, args ) → GetEventInfo<TEvent>[ 'return' ]

    See source

    Fires an event, executing all callbacks registered for it.

    The first parameter passed to callbacks is an EventInfo object, followed by the optional args provided in the fire() method call.

    Type parameters

    TEvent : extends BaseEvent

    The type describing the event. See BaseEvent.

    Parameters

    eventOrInfo : GetNameOrEventInfo<TEvent>

    The name of the event or EventInfo object if event is delegated.

    args : TEvent[ 'args' ]

    Additional arguments to be passed to the callbacks.

    Returns

    GetEventInfo<TEvent>[ 'return' ]

    By default the method returns undefined. However, the return value can be changed by listeners through modification of the evt.return's property (the event info is the first param of every callback).

  • focus() → void

    See source

    Focuses the queryView.

    Returns

    void

  • inherited

    listenTo( emitter, event, callback, [ options ] ) → void

    See source

    Registers a callback function to be executed when an event is fired in a specific (emitter) object.

    Events can be grouped in namespaces using :. When namespaced event is fired, it additionally fires all callbacks for that namespace.

    // myEmitter.on( ... ) is a shorthand for myEmitter.listenTo( myEmitter, ... ).
myEmitter.on( 'myGroup', genericCallback );
myEmitter.on( 'myGroup:myEvent', specificCallback );

// genericCallback is fired.
myEmitter.fire( 'myGroup' );
// both genericCallback and specificCallback are fired.
myEmitter.fire( 'myGroup:myEvent' );
// genericCallback is fired even though there are no callbacks for "foo".
myEmitter.fire( 'myGroup:foo' );

    An event callback can stop the event and set the return value of the fire method.

    registerChild( children ) → void

    See source

    Registers a new child view under the view instance. Once registered, a child view is managed by its parent, including rendering and destruction.

    To revert this, use deregisterChild.

    class SampleView extends View {
	constructor( locale ) {
		super( locale );

		this.childA = new SomeChildView( locale );
		this.childB = new SomeChildView( locale );

		this.setTemplate( { tag: 'p' } );

		// Register the children.
		this.registerChild( [ this.childA, this.childB ] );
	}

	render() {
		super.render();

		this.element.appendChild( this.childA.element );
		this.element.appendChild( this.childB.element );
	}
}

const view = new SampleView( locale );

view.render();

// Will append <p><childA#element><b></b><childB#element></p>.
document.body.appendChild( view.element );

    Note: There's no need to add child views if they're already referenced in the template:

    class SampleView extends View {
	constructor( locale ) {
		super( locale );

		this.childA = new SomeChildView( locale );
		this.childB = new SomeChildView( locale );

		this.setTemplate( {
			tag: 'p',

 * 			// These children will be added automatically. There's no
 * 			// need to call registerChild for any of them.
			children: [ this.childA, this.childB ]
		} );
	}

	// ...
}

    Parameters

    children : View<HTMLElement> | Iterable<View<HTMLElement>>

    Children views to be registered.

    Returns

    void

  • render() → void

    See source

    Recursively renders the view.

    Once the view is rendered:

    Note: The children of the view:

    In general, render() method is the right place to keep the code which refers to the element and should be executed at the very beginning of the view's life cycle.

    It is possible to extend the template before the view is rendered. To allow an early customization of the view (e.g. by its parent), such references should be done in render().

    class SampleView extends View {
	constructor() {
		this.setTemplate( {
			// ...
		} );
	},

	render() {
		// View#element becomes available.
		super.render();

		// The "scroll" listener depends on #element.
		this.listenTo( window, 'scroll', () => {
			// A reference to #element would render the #template and make it non-extendable.
			if ( window.scrollY > 0 ) {
				this.element.scrollLeft = 100;
			} else {
				this.element.scrollLeft = 0;
			}
		} );
	}
}

const view = new SampleView();

// Let's customize the view before it gets rendered.
view.extendTemplate( {
	attributes: {
		class: [
			'additional-class'
		]
	}
} );

// Late rendering allows customization of the view.
view.render();

    set( values ) → void

    See source

    Creates and sets the value of an observable properties of this object. Such a property becomes a part of the state and is observable.

    It accepts a single object literal containing key/value pairs with properties to be set.

    This method throws the observable-set-cannot-override error if the observable instance already has a property with the given property name. This prevents from mistakenly overriding existing properties and methods, but means that foo.set( 'bar', 1 ) may be slightly slower than foo.bar = 1.

    In TypeScript, those properties should be declared in class using declare keyword. In example:

    public declare myProp1: number;
public declare myProp2: string;

constructor() {
	this.set( {
		'myProp1: 2,
		'myProp2: 'foo'
	} );
}

    Parameters

    values : object

    An object with name=>value pairs.

    Returns

    void
