var get_ie_version = function () {
    var sAgent = window.navigator.userAgent;
    var Idx = sAgent.indexOf("MSIE");

    // If IE, return version number.
    if (Idx > 0) {
        return parseInt(sAgent.substring(Idx+ 5, sAgent.indexOf(".", Idx)));
    }
    // Condition Check IF IE 11 and or MS Edge
    else if ( !!navigator.userAgent.match(/Trident\/7\./)
        || window.navigator.userAgent.indexOf("Edge") > -1 )
    {
        return 11;
    } else {
        return 0; //It is not IE
    }
};
