Text (engine/view)

@ckeditor/ckeditor5-engine/src/view/text

class
See source

Tree view text node.

The constructor of this class shouldn't be used directly. To create new Text instances use the DowncastWriter#createText() method when working on data downcasted from the model or the UpcastWriter#createText() method when working on non-semantic views.

Filtering

Properties

  • data : String

    readonly

    The text content.

    See source

  • document : Document | null

    readonly inherited

    View document that owns this node, or null if the node is inside document fragment.

    See source

  • index : Number | null

    readonly inherited

    Index of the node in the parent element or null if the node has no parent.

    See source

    Accessing this property throws an error if this node's parent element does not contain it. This means that view tree got broken.

  • nextSibling : Node | null

    readonly inherited

    Node's next sibling, or null if it is the last child.

    See source

  • parent : Element | DocumentFragment | null

    readonly inherited

    Parent element. Null by default. Set by _insertChild.

    See source

  • previousSibling : Node | null

    readonly inherited

    Node's previous sibling, or null if it is the first child.

    See source

  • root : Node | DocumentFragment

    readonly inherited

    Top-most ancestor of the node. If the node has no parent it is the root itself.

    See source

  • _data

    protected

    Sets data and fires the change event.

    See source

    Parameters

    data : String

    New data for the text node.

  • _textData : String

    protected

    The text content.

    See source

    Setting the data fires the change event.

Methods

  • constructor( data )

    protected

    Creates a tree view text node.

    See source

    Parameters

    data : String

    The text's data.

  • getAncestors( options = { [options.includeSelf], [options.parentFirst] } ) → Array

    inherited

    Returns ancestors array of this node.

    See source

    Parameters

    options : Object

    Options object.

    Properties
    [ options.includeSelf ] : Boolean

    When set to true this node will be also included in parent's array.

    Defaults to false

    [ options.parentFirst ] : Boolean

    When set to true, array will be sorted from node's parent to root element, otherwise root element will be the first item in the array.

    Defaults to false

    Returns

    Array

    Array with ancestors.

  • getCommonAncestor( node, options = { [options.includeSelf] } ) → Element | DocumentFragment | null

    inherited

    Returns a Element or DocumentFragment which is a common ancestor of both nodes.

    See source

    Parameters

    node : Node

    The second node.

    options : Object

    Options object.

    Properties
    [ options.includeSelf ] : Boolean

    When set to true both nodes will be considered "ancestors" too. Which means that if e.g. node A is inside B, then their common ancestor will be B.

    Defaults to false

    Returns

    Element | DocumentFragment | null

  • getPath() → Array.<Number>

    inherited

    Gets a path to the node. The path is an array containing indices of consecutive ancestors of this node, beginning from root, down to this node's index.

    See source
    const abc = downcastWriter.createText( 'abc' );
const foo = downcastWriter.createText( 'foo' );
const h1 = downcastWriter.createElement( 'h1', null, downcastWriter.createText( 'header' ) );
const p = downcastWriter.createElement( 'p', null, [ abc, foo ] );
const div = downcastWriter.createElement( 'div', null, [ h1, p ] );
foo.getPath(); // Returns [ 1, 3 ]. `foo` is in `p` which is in `div`. `p` starts at offset 1, while `foo` at 3.
h1.getPath(); // Returns [ 0 ].
div.getPath(); // Returns [].

    Returns

    Array.<Number>

    The path.

  • is( type ) → Boolean

    inherited

    Checks whether given view tree object is of given type.

    See source

    This method is useful when processing view tree objects that are of unknown type. For example, a function may return DocumentFragment or Node that can be either text node or element. This method can be used to check what kind of object is returned.

    obj.is( 'node' ); // true for any node, false for document fragment and text fragment
obj.is( 'documentFragment' ); // true for document fragment, false for any node
obj.is( 'element' ); // true for any element, false for text node or document fragment
obj.is( 'element', 'p' ); // true only for element which name is 'p'
obj.is( 'p' ); // shortcut for obj.is( 'element', 'p' )
obj.is( 'text' ); // true for text node, false for element and document fragment

    Parameters

    type : 'element' | 'containerElement' | 'attributeElement' | 'emptyElement' | 'uiElement' | 'rootElement' | 'documentFragment' | 'text' | 'textProxy'

    Returns

    Boolean

  • isAfter( node ) → Boolean

    inherited

    Returns whether this node is after given node. false is returned if nodes are in different trees (for example, in different DocumentFragments).

    See source

    Parameters

    node : Node

    Node to compare with.

    Returns

    Boolean

  • isBefore( node ) → Boolean

    inherited

    Returns whether this node is before given node. false is returned if nodes are in different trees (for example, in different DocumentFragments).

    See source

    Parameters

    node : Node

    Node to compare with.

    Returns

    Boolean

  • isSimilar( otherNode ) → Boolean

    Checks if this text node is similar to other text node. Both nodes should have the same data to be considered as similar.

    See source

    Parameters

    otherNode : Text

    Node to check if it is same as this node.

    Returns

    Boolean

  • toJSON() → Object

    inherited

    Custom toJSON method to solve child-parent circular dependencies.

    See source

    Returns

    Object

    Clone of this object with the parent property removed.

  • _clone() → Text

    protected

    Clones this node.

    See source
