Range

The Range interface represents a fragment of a document that can contain nodes and parts of text nodes.

A range can be created by using the Document.createRange() method. Range objects can also be retrieved by using the getRangeAt() method of the Selection object or the caretRangeFromPoint() method of the Document object.

There also is the Range() constructor available.

There are no inherited properties.

Range.collapsed Read only

Returns a boolean value indicating whether the range's start and end points are at the same position.

Range.commonAncestorContainer Read only

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

Range.endContainer Read only

Returns the Node within which the Range ends.

Range.endOffset Read only

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

Range.startContainer Read only

Returns the Node within which the Range starts.

Range.startOffset Read only

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

Range() Experimental

Returns a Range object with the global Document as its start and end.

There are no inherited methods.

Range.collapse()

Collapses the Range to one of its boundary points.

Range.compareBoundaryPoints()

Compares the boundary points of the Range with another Range.

Range.compareNode() Deprecated Non-Standard

Returns a constant representing whether the Node is before, after, inside, or surrounding the range.

Range.comparePoint() Experimental

Returns -1, 0, or 1 indicating whether the point occurs before, inside, or after the Range.

Range.cloneContents()

Returns a DocumentFragment copying the nodes of a Range.

Range.cloneRange()

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

Range.createContextualFragment() Experimental

Returns a DocumentFragment created from a given string of code.

Range.deleteContents()

Removes the contents of a Range from the Document.

Range.detach()

Releases the Range from use to improve performance.

Range.extractContents()

Moves contents of a Range from the document tree into a DocumentFragment.

Range.getBoundingClientRect() Experimental

Returns a DOMRect object which bounds the entire contents of the Range; this would be the union of all the rectangles returned by range.getClientRects().

Range.getClientRects() Experimental

Returns a list of DOMRect objects that aggregates the results of Element.getClientRects() for all the elements in the Range.

Range.isPointInRange() Experimental

Returns a boolean indicating whether the given point is in the Range.

Range.insertNode()

Insert a Node at the start of a Range.

Range.intersectsNode() Experimental

Returns a boolean indicating whether the given node intersects the Range.

Range.selectNode()

Sets the Range to contain the Node and its contents.

Range.selectNodeContents()

Sets the Range to contain the contents of a Node.

Range.setEnd()

Sets the end position of a Range.

Range.setStart()

Sets the start position of a Range.

Range.setEndAfter()

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

Range.setEndBefore()

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

Range.setStartAfter()

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

Range.setStartBefore()

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

Range.surroundContents()

Moves content of a Range into a new Node.

Range.toString()

Returns the text of the Range.
