goog.dom.Range

Provided By	`goog.dom.Range`

Clears the window's selection.

Parameters

`opt_win`	`(Window\|null)=`
	The window to get the selection of. Defaults to the window this class was defined in.

VIEW SOURCE

Create a new range wrapper that represents a caret at the given node, accounting for the given offset. This always creates a TextRange, regardless of whether node is an image node or other control range type node.

Parameters

`node`	`(Node\|null)`
	The node to place a caret at.
`offset`	`number`
	The offset within the node to place the caret at.

Returns

goog.dom.AbstractRange

A range wrapper object.

VIEW SOURCE

Create a new range wrapper from the given browser range object.

Parameters

`range`	`(Range\|TextRange\|null)`
	The browser range object.
`opt_isReversed`	`boolean=`
	Whether the focus node is before the anchor node.

Returns

goog.dom.AbstractRange

A range wrapper object.

VIEW SOURCE

Create a new range wrapper from the given browser selection object. Note that this object does not auto-update if the user changes their selection and should be used as a snapshot.

Parameters

`selection`	`Object`
	The browser selection object.

Returns

(goog.dom.AbstractRange|null)

A range wrapper object or null if there was an error.

VIEW SOURCE

Create a new range wrapper that selects the given node's text.

Parameters

`node`	`(Node\|null)`
	The node to select.
`opt_isReversed`	`boolean=`
	Whether the focus node is before the anchor node.

Returns

goog.dom.AbstractRange

A range wrapper object.

VIEW SOURCE

Create a new range wrapper that selects the area between the given nodes, accounting for the given offsets.

Parameters

`anchorNode`	`(Node\|null)`
	The node to anchor on.
`anchorOffset`	`number`
	The offset within the node to anchor on.
`focusNode`	`(Node\|null)`
	The node to focus on.
`focusOffset`	`number`
	The offset within the node to focus on.

Returns

goog.dom.AbstractRange

A range wrapper object.

VIEW SOURCE

Create a new selection from the given browser window's current selection. Note that this object does not auto-update if the user changes their selection and should be used as a snapshot.

Parameters

`opt_win`	`(Window\|null)=`
	The window to get the selection of. Defaults to the window this class was defined in.

Returns

(goog.dom.AbstractRange|null)

A range wrapper object, or null if there was an error.

VIEW SOURCE

Tests if the window has a selection.

Parameters

`opt_win`	`(Window\|null)=`
	The window to check the selection of. Defaults to the window this class was defined in.

Returns

boolean

Whether the window has a selection.

VIEW SOURCE

Returns whether the focus position occurs before the anchor position.

Parameters

`anchorNode`	`(Node\|null)`
	The node to anchor on.
`anchorOffset`	`number`
	The offset within the node to anchor on.
`focusNode`	`(Node\|null)`
	The node to focus on.
`focusOffset`	`number`
	The offset within the node to focus on.

Returns

boolean

Whether the focus position occurs before the anchor position.
