The Selection.containsNode() method indicates if the node is part of the selection.

Syntax

sel.containsNode(node, partialContainment)

Parameters

node
The node that is being looked for in the selection.

When true, containsNode() returns true when a part of the node is part of the selection. When false, containsNode() only returns true when the entire node is part of the selection. If not specified, the default value false is used.

Examples
