focusNode property (selectionRange)
Returns a reference to the element where the selection ends.
Note: The selectionRange object and its focusNode property are supported in Internet Explorer from version 9.The focus point is the point where the process of selecting was ended. The focus node is the deepest node in the DOM hierarchy that contains the focus point.
In most cases, the focusNode property refers to a TextNode.
In that case, the focusOffset property returns the character position within the text content of the focus node where the selection ends.
- However, in some cases (for example when the entire contents of the page are selected with Ctrl+A) the focusNode property refers to a node that can have child nodes.
Similarly, the anchor point is the point where the process of selecting was started. The anchor node is the deepest node in the DOM hierarchy that contains the anchor point. The anchorOffset property returns the position of the anchor point relative to the anchor node.
The selectionRange object represents the current selection and every Range object that belongs to the selectionRange object represents a contiguous part of the selection. You can get the Range objects that belong to the selectionRange object with the getRangeAt method. The startContainer, startOffset, endContainer and endOffset properties of the Range object are similar to the anchorNode, anchorOffset, focusNode and focusOffset properties of the selectionRange object.The properties mentioned above belong to the selectionRange object, which is not supported by Internet Explorer before version 9. If you want to get or manipulate the selection in that browsers (and optionally in newer ones as well), use the selection object with the createRange or createRangeCollection method.
- In Internet Explorer, Opera, Google Chrome, Safari and Firefox before version 3, at most one Range can belong to the selectionRange object, because text selection is always a contiguous part of the DOM hierarchy. In that case, using the anchorNode, anchorOffset, focusNode and focusOffset properties of the selectionRange object is simpler than using the properties of the Range object that belongs to the selectionRange object.
- In Firefox from version 3, multiple areas of text can be selected by holding down the CTRL key while selecting. If multiple ranges are added to the selection (by the user or by script, see the addRange method), then use the properties of the Range objects of the selection for similar functionality.
