Internal
not part of the DOM
Compare the boundary-points of a range. Return true if the startContainer is before the endContainer, or if they are equal. Return false if the startContainer is after the endContainer. |
|
Duplicates the contents of a range
Returns A DocumentFragment containing contents equivalent to those of this range. DOMException HIERARCHY_REQUEST_ERR: Raised if a DocumentType node would be extracted into the new DocumentFragment. |
|
Produces a new range whose end-points are equal to the
end-points of the range.
Returns The duplicated range. |
|
Collapse a range onto one of its end-points
toStart - If true, collapses the Range onto its start; if false, collapses it onto its end. Returns |
|
true if the range is collapsed |
|
Gets the common ancestor container of the range's two end-points. Also sets it. |
|
Compare the end-points of two ranges in a document.
how - sourceRange - Returns -1, 0 or 1 depending on whether the corresponding end-point of the Range is before, equal to, or after the corresponding end-point of sourceRange . DOMException WRONG_DOCUMENT_ERR: Raised if the two Ranges are not in the same document or document fragment. |
|
|
Removes the contents of a range from the containing document or
document fragment without returning a reference to the removed
content.
Returns DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if any portion of the content of the range is read-only or any of the nodes that contain any of the content of the range are read-only. |
|
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. |
|
Node within which the range ends |
|
Offset within the ending node of the range. |
|
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. |
|
Internal not part of the DOM |
|
Inserts a node into the document or document fragment at the
start of the range.
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. |
|
not part of the DOM true if the range is detached |
|
|
Select a node and its contents
refNode - The node to select. Returns RangeException INVALID_NODE_TYPE_ERR: Raised if an ancestor of refNode is an Attr, Entity, Notation or DocumentType node or if refNode is a Document, DocumentFragment, Attr, Entity, or Notation node. |
|
Select the contents within a node
refNode - Node to select from Returns RangeException INVALID_NODE_TYPE_ERR: Raised if refNode or an ancestor of refNode is an Attr, Entity, Notation or DocumentType node. |
|
Sets the attributes describing the end of a range.
refNode - The refNode value. This parameter must be different from null . offset - The endOffset value. Returns RangeException NULL_NODE_ERR: Raised if refNode is null . INVALID_NODE_TYPE_ERR: Raised if refNode or an ancestor of refNode is an Attr, Entity, Notation, or DocumentType node. |
|
Sets the end of a range to be after a node
refNode - Range ends after refNode . Returns RangeException INVALID_NODE_TYPE_ERR: Raised if an ancestor of refNode is an Attr, Entity, Notation or DocumentType node or if refNode is a Document, DocumentFragment, Attr, Entity, or Notation node. |
|
Sets the end position to be before a node.
refNode - Range ends before refNode Returns RangeException INVALID_NODE_TYPE_ERR: Raised if an ancestor of refNode is an Attr, Entity, Notation, or DocumentType node or if refNode is a Document, DocumentFragment, Attr, Entity, or Notation node. |
|
Sets the attributes describing the start of the range.
refNode - The refNode value. This parameter must be different from null . offset - The startOffset value. Returns RangeException NULL_NODE_ERR: Raised if refNode is null . INVALID_NODE_TYPE_ERR: Raised if refNode or an ancestor of refNode is an Attr, Entity, Notation, or DocumentType node. If an offset is out-of-bounds, should it just be fixed up or should an exception be raised. |
|
Sets the start position to be after a node
refNode - Range starts after refNode Returns RangeException INVALID_NODE_TYPE_ERR: Raised if an ancestor of refNode is an Attr, Entity, Notation, or DocumentType node or if refNode is a Document, DocumentFragment, Attr, Entity, or Notation node. |
|
Sets the start position to be before a node
refNode - Range starts before refNode Returns RangeException INVALID_NODE_TYPE_ERR: Raised if an ancestor of refNode is an Attr, Entity, Notation, or DocumentType node or if refNode is a Document, DocumentFragment, Attr, Entity, or Notation node. |
|
Node within which the range begins |
|
Offset within the starting node of the range. |
|
Reparents the contents of the range to the given node and
inserts the node at the position of the start of the range.
newParent - The node to surround the contents with. Returns DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if an ancestor container of either end-point of the range is read-only. WRONG_DOCUMENT_ERR: Raised if newParent 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 newParent or if newParent is an ancestor of the container or if node would end up with a child node of a type not allowed by the type of node . RangeException BAD_ENDPOINTS_ERR: Raised if the range partially selects a non-text node. INVALID_NODE_TYPE_ERR: Raised if node is an Attr, Entity, DocumentType, Notation, Document, or DocumentFragment node. |
