    Range.setStart()

    The Range.setStart() method sets the start position of a Range.

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

    Setting the start point below (further down in the document) than the end point will throw an ERROR_ILLEGAL_VALUE DOMException.

    Syntax

    range.setStart(startNode, startOffset);
    

    Parameters

    startNode
    The Node where the Range should start.
    startOffset 
    An integer greater than or equal to zero representing the offset for the start of the Range from the start of startNode.

    Example

    var range = document.createRange();
    var startNode = document.getElementsByTagName("p").item(2);
    var startOffset = 0;
    range.setStart(startNode,startOffset);
