Js code to get browser name and version:

    var N=navigator.appName, ua=navigator.userAgent, tem;
    var M=ua.match(/(opera|chrome|safari|firefox|msie)\/?\s*(\.?\d+(\.\d+)*)/i);
    if(M && (tem= ua.match(/version\/([\.\d]+)/i))!= null) M[2]= tem[1];
    M=M? [M[1], M[2]]: [N, navigator.appVersion, '-?'];
    return M[0];
    }
function get_browser_version(){
    var N=navigator.appName, ua=navigator.userAgent, tem;
    var M=ua.match(/(opera|chrome|safari|firefox|msie)\/?\s*(\.?\d+(\.\d+)*)/i);
    if(M && (tem= ua.match(/version\/([\.\d]+)/i))!= null) M[2]= tem[1];
    M=M? [M[1], M[2]]: [N, navigator.appVersion, '-?'];
    return M[1];
    }
