DOM 2 Range Interface

Properties

collapsed

Returns a boolean indicating whether a range is collapsed.

commonAncestorContainer

Returns the deepest Node that contains the startContainer and endContainer Nodes.

endContainer

Returns the Node within which the Range ends.

endOffset

Returns a number representing where in the endContainer the Range ends.

startContainer

Returns the Node within which the Range starts.

startOffset

Returns a number representing where in the startContainer the Range starts.

Creation Methods

createRange

Returns a new Range object.

setStart

Sets the start position of a Range.

setEnd

Sets the end position of a Range.

setStartBefore

Sets the start position of a Range relative to another Node.

setStartAfter

Sets the start position of a Range relative to another Node.

setEndBefore

Sets the end position of a Range relative to another Node.

setEndAfter

Sets the end position of a Range relative to another Node.

selectNode

Sets the Range to contain the node and its contents.

selectNodeContents

Sets the Range to contain the contents of a Node.

Editing Methods

collapse

Collapses the Range to one of its boundary points.

cloneContents

Returns a document fragment copying the nodes of a Range.

deleteContents

Removes the contents of a Range from the document.

extractContents

Moves contents of a Range from the document tree into a document fragment

insertNode

Insert a node at the start of a Range.

surroundContents

Moves content of a Range into a new node.

Other Methods

compareBoundaryPoints

Compares the boundary points of two Ranges.

cloneRange

Returns a Range object with boundary points identical to the cloned Range.

detach

Releases Range from use to improve performance.

toString

Returns the text of the Range.
