Properties
-
Custom suggestion attributes. See also
setAttribute
andremoveAttribute
. -
author : User
module:track-changes/suggestion~Suggestion#author
The author of the change marked by the suggestion.
-
Date when the change marked by the suggestion was made.
Usually the same as
createdAt
but may be different in some cases (e.g. when suggestion was added from an external source). -
Comment thread model for comments added to this suggestion.
-
createdAt : null | Date
module:track-changes/suggestion~Suggestion#createdAt
Date when the suggestion was saved in the database.
-
creator : User
module:track-changes/suggestion~Suggestion#creator
The user which saved the suggestion data in the database.
Usually the same as author but may be different in some cases (e.g. when suggestion was added from an external source).
-
data : null | FormatData | AttributeData
module:track-changes/suggestion~Suggestion#data
Additional suggestion data.
-
Informs whether suggestion has at least one comment.
-
The first (most-previous) suggestion in this suggestion chain.
-
Suggestion ID.
-
isExternal : boolean
module:track-changes/suggestion~Suggestion#isExternal
The flag indicating whether the suggestion comes from an external source.
-
Informs whether the suggestion is still in the editor content.
Returns
true
if there is at least one marker suggestion in the editor content. -
Informs whether the suggestion is a multi-range suggestion or a single-range suggestion.
This is evaluated basing on the marker name belonging to this suggestion. Even if only one marker belongs to the suggestion at a given time it can still be a multi range suggestion.
-
Next suggestion in suggestions chain.
Chained suggestions should be handled as one entity.
-
Previous suggestion in suggestions chain.
Chained suggestions should be handled as one entity.
-
subType : null | string
module:track-changes/suggestion~Suggestion#subType
Suggestion sub-type.
This is an additional identifier for suggestions. Two suggestions of the same type may have different sub-types to differentiate suggestions behavior and handle interactions between suggestions.
Sub-type is used for:
- suggestions joining (only suggestions with the same sub-type can be joined),
- suggestions custom callbacks (fired when adding, deleting and joining suggestions).

bind( bindProperty1, bindProperty2 ) → DualBindChain<K1, Suggestion[ K1 ], K2, Suggestion[ K2 ]>
module:track-changes/suggestion~Suggestion#bind:DUAL_BIND
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 associatedcommand
(bothObservable
).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 equalscommand.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 (alsoObservables
) 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

Parameters
bindProperty1 : K1

bindProperty2 : K2
Observable property that will be bound to other observable(s).
Returns
DualBindChain<K1, Suggestion[ K1 ], K2, Suggestion[ K2 ]>
The bind chain with the
to()
andtoMany()
methods.

-
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 : 'type' | 'off' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'data' | 'head' | 'attributes' | 'id' | 'removeAttribute' | 'setAttribute' | 'toJSON' | 'removeMarker' | 'next' | 'accept' | 'previous' | 'authoredAt' | 'author' | 'creator' | 'isExternal' | 'createdAt' | 'subType' | 'commentThread' | '_saved' | '_isDataLoaded' | '_onAccept' | '_onDiscard' | 'hasComments' | 'isMultiRange' | 'isInContent' | 'addMarkerName' | 'getMarkerNames' | 'getMarkers' | 'getFirstMarker' | 'removeMarkers' | 'addRange' | 'isIntersectingWithRange' | 'getRanges' | 'getItems' | 'getFirstRange' | 'getContainedElement' | 'discard' | 'getAllAdjacentSuggestions'

listenTo( emitter, event, callback, [ options ] ) → void
module:track-changes/suggestion~Suggestion#listenTo:BASE_EMITTER
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.Type parameters

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 thatfoo.set( 'bar', 1 )
may be slightly slower thanfoo.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

suggestion.setAttribute( 'isImportant', true );
You can group multiple values in an object, using dot notation:
suggestion.setAttribute( 'customData.type', 'image' ); suggestion.setAttribute( 'customData.src', 'foo.jpg' );
Attributes set on the suggestion can be accessed through
attribute
property:const isImportant = suggestion.attributes.isImportant; const type = suggestion.attributes.customData.type;
You can also observe
attributes
property or bind other properties to it:myObj.bind( 'customData' ).to( suggestion, 'attributes', attributes => attributes.customData );
Whenever
setAttribute()
orremoveAttribute()
