    Range.comparePoint

    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 Range.comparePoint() method returns -1, 0, or 1 depending on whether the referenceNode is before, the same as, or after the Range.

    If the reference node is a Node of type Text, Comment, or CDATASection, then offset is the number of characters from the start of reference node. For other Node types, offset is the number of child nodes between the start of the reference node.

    Syntax

    returnValue = range.comparePoint( referenceNode, offset )
    

    Parameters

    referenceNode
    The Node to compare with the Range.
    offset
    An integer greater than or equal to zero representing the offset inside the referenceNode.

    Example

    range = document.createRange();
    range.selectNode(document.getElementsByTagName("div").item(0));
    returnValue = range.comparePoint(document.getElementsByTagName("p").item(0),1);
