    Selection.containsNode()

    This is an experimental technology
    Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.

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

    Syntax

    sel.containsNode(
    aNode,
    aPartlyContained)
    

    Parameters

    aNode
    The node that is being looked for whether it is part of the selection
    aPartlyContained
    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.

    Examples

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