ckeditor5-elements / ElementDeleteCommand

Class: ElementDeleteCommand

Deletes an element. When it was the only element in its parent, e.g. in a note, the parent gets an empty paragraph with the selection, so that it can still be written in.

The element is the given one, the parent of the given position, or the selected element or the parent of the selection (see ElementOrPositionCommand). The command is disabled for parts of a structure, such as table cells.

Constructors

Constructor

new ElementDeleteCommand(editor): ElementDeleteCommand;

Parameters

Parameter	Type
editor	Editor

Returns

ElementDeleteCommand

Overrides

ElementOrPositionCommand.constructor

Properties

icon

icon: string | undefined;

Observable

The icon (SVG string) of the command.

Inherited from

ElementOrPositionCommand.icon

---

isForceDisabled

readonly isForceDisabled: boolean;

Observable

Whether the command is disabled with forceDisabled() (and not enabled back with clearForceDisabled() for every id), so it is disabled for every target.

Inherited from

ElementOrPositionCommand.isForceDisabled

---

isToggleable

isToggleable: boolean = false;

Whether the command can be "on" (see _isOnFor), e.g. because it toggles something. Its buttons then tell assistive technology whether it is on: toolbar buttons with aria-pressed, menu items with aria-checked. Defaults to false; the commands of one element that toggle it set it, e.g. ElementInlineCommand.

Inherited from

ElementOrPositionCommand.isToggleable

---

title

title: string;

Observable

The title of the command.

Inherited from

ElementOrPositionCommand.title

---

tooltip

tooltip: string | boolean;

Observable

The tooltip of the command. true uses the title.

Inherited from

ElementOrPositionCommand.tooltip

Methods

_getElement()

protected _getElement(elementOrPosition?): 
  | ModelElement
  | null;

Resolves the target (see _getElementOrPosition) to an element: a position becomes its parent element. Never returns a root.

Parameters

Parameter	Type
elementOrPosition?	ElementOrPosition

Returns

| ModelElement | null

Inherited from

ElementOrPositionCommand._getElement

---

_getElementOrPosition()

protected _getElementOrPosition(elementOrPosition?): ElementOrPosition | null;

Returns the given position or element, or resolves it from the current selection when absent. Returns null for a target that is not in the document (any more), e.g. a removed element, so commands ignore such targets.

Parameters

Parameter	Type
elementOrPosition?	ElementOrPosition

Returns

ElementOrPosition | null

Inherited from

ElementOrPositionCommand._getElementOrPosition

---

_getPosition()

protected _getPosition(elementOrPosition?): 
  | ModelPosition
  | null;

Resolves the target (see _getElementOrPosition) to a position: an element becomes the position before it.

Parameters

Parameter	Type
elementOrPosition?	ElementOrPosition

Returns

| ModelPosition | null

Inherited from

ElementOrPositionCommand._getPosition

---

_getStateFor()

protected _getStateFor(elementOrPosition?): ElementOrPositionState;

Returns whether the command is enabled and "on" for the target, before read-only mode and forceDisabled(): the one source of the state, for refresh and getState. By default, from _isEnabledFor and _isOnFor.

Parameters

Parameter	Type
elementOrPosition?	ElementOrPosition

Returns

ElementOrPositionState

Inherited from

ElementOrPositionCommand._getStateFor

---

_isEnabledFor()

protected _isEnabledFor(elementOrPosition?): boolean;

Whether the command is enabled for the target. By default: when there is a target and it can be edited.

Parameters

Parameter	Type
elementOrPosition?	ElementOrPosition

Returns

boolean

Overrides

ElementOrPositionCommand._isEnabledFor

---

_isOnFor()

protected _isOnFor(elementOrPosition?): boolean;

Whether the command is "on" for the target. By default: never. Commands that override it should set isToggleable.

Parameters

Parameter	Type
elementOrPosition?	ElementOrPosition

Returns

boolean

Inherited from

ElementOrPositionCommand._isOnFor

---

_requireElement()

protected _requireElement(elementOrPosition?): ModelElement;

Returns the element of the target (see _getElement), in execute() of a command that is enabled only for a target with an element: execute() runs only then, so there is one. Throws when there is none.

Parameters

Parameter	Type
elementOrPosition?	ElementOrPosition

Returns

ModelElement

Inherited from

ElementOrPositionCommand._requireElement

---

clearForceDisabled()

clearForceDisabled(id): void;

Clears the disabling done by forceDisabled with this id. When no id is left, the command is refreshed, so isEnabled follows the selection again.

Parameters

Parameter	Type
id	string

Returns

void

Inherited from

ElementOrPositionCommand.clearForceDisabled

---

execute()

execute(elementOrPosition?): void;

Deletes the element.

Parameters

Parameter	Type
elementOrPosition?	ElementOrPosition

Returns

void

Overrides

ElementOrPositionCommand.execute

---

executeFor()

executeFor(elementOrPosition, ...args): unknown;

Executes the command for the target, even when the command is disabled for the selection (execute() checks isEnabled, which follows the selection). Does nothing when the command is disabled for the target.

The target is the first argument of execute(); the other arguments are passed after it.

Parameters

Parameter	Type
elementOrPosition	ElementOrPosition
...args	unknown[]

Returns

unknown

Inherited from

ElementOrPositionCommand.executeFor

---

forceDisabled()

forceDisabled(id): void;

Disables the command for every target until it is enabled back with clearForceDisabled for every id it was disabled with. See isForceDisabled.

Parameters

Parameter	Type
id	string

Returns

void

Inherited from

ElementOrPositionCommand.forceDisabled

---

getState()

getState(elementOrPosition?): ElementOrPositionState;

Returns whether the command would be enabled and "on" for the target, without changing isEnabled. Commands that change the data are disabled in read-only mode, and all commands are disabled when isForceDisabled.

Parameters

Parameter	Type
elementOrPosition?	ElementOrPosition

Returns

ElementOrPositionState

Inherited from

ElementOrPositionCommand.getState

---

refresh()

refresh(elementOrPosition?): void;

Sets isEnabled for the target (by default, the selection). See _getStateFor.

Parameters

Parameter	Type
elementOrPosition?	ElementOrPosition

Returns

void

Inherited from

ElementOrPositionCommand.refresh
