detach | ( |  | self ) |

Called to indicate that the range is no longer in use and that the implementation may relinquish any resources associated with this range. Subsequent calls to any methods or attribute getters on this range will result in a DOMException being thrown with an error code of INVALID_STATE_ERR.

long endOffset | ( |  | self ) |

Offset within the ending node of the range.

DOM.DocumentFragment extractContents | ( |  | self ) |

Moves the contents of a range from the containing document or document fragment to a new DocumentFragment.

Returns:
  A DocumentFragment containing the extracted contents.

DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if any portion of the content of the range is read-only or any of the nodes which contain any of the content of the range are read-only.

HIERARCHY_REQUEST_ERR: Raised if a DocumentType node would be extracted into the new DocumentFragment.

insertNode | ( | self, |
|  | DOM.Node | newNode
| ) |  |  |

Inserts a node into the document or document fragment at the start of the range.

Parameters:

  | newNode | The node to insert at the start of the range

Returns:

DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if an ancestor container of the start of the range is read-only.

WRONG_DOCUMENT_ERR: Raised if newNode and the container of the start of the Range were not created from the same document.

HIERARCHY_REQUEST_ERR: Raised if the container of the start of the Range is of a type that does not allow children of the type of newNode or if newNode is an ancestor of the container .

RangeException INVALID_NODE_TYPE_ERR: Raised if node is an Attr, Entity, Notation, DocumentFragment, or Document node.

bool isDetached | ( |  | self ) |

not part of the DOM true if the range is detached

selectNodeContents | ( | self, |
|  | DOM.Node | refNode
| ) |  |  |

Select the contents within a node

Parameters:

  | refNode | Node to select from
