This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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.
partialContainment Optional
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.

Example

 /* Check to see if anything inside the body element is selected */
 console.log(window.getSelection().containsNode(document.body, true));
