JS获取设备信息

获取设备类型名称：

方法一：

function browerType() {

    var sUserAgent = navigator.userAgent.toLowerCase();  //浏览器的用户代理设置为小写，再进行匹配

    var isIpad = sUserAgent.match(/ipad/i) == "ipad";  //或者利用indexOf方法来匹配

    var isIphoneOs = sUserAgent.match(/iphone os/i) == "iphone";

    var isMidp = sUserAgent.match(/midp/i) == "midp";  //移动信息设备描述MIDP是一套Java应用编程接口，多适用于塞班系统

    var isUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";  //CVS标签

    var isUc = sUserAgent.match(/ucweb/i) == "ucweb";

    var isAndroid = sUserAgent.match(/android/i) == "android";

    var isCe = sUserAgent.match(/windows ce/i) == "windows ce";

    var isWM = sUserAgent.match(/windows mobil/i) == "windows mobil";

    if (isIpad || isIphoneOs || isMidp || isUc7 || isUc || isAndroid || isCe || isWM) {

        alert('该设备为移动设备');

    } else {

        alert('该设备为PC设备');

    }

}

方法二：

function detectOS() {

    var sUserAgent = navigator.userAgent;

    var isWin = (navigator.platform == "Win32") || (navigator.platform == "Windows");

    var isMac = (navigator.platform == "Mac68K") || (navigator.platform == "MacPPC") || (navigator.platform == "Macintosh") || (navigator.platform == "MacIntel");

    if (isMac) return "Mac";

     var isUnix = (navigator.platform == "X11") && !isWin && !isMac;

    if (isUnix) return "Unix";

    var isLinux = (String(navigator.platform).indexOf("Linux") > -1);

    var bIsAndroid = sUserAgent.toLowerCase().match(/android/i) == "android";

    if (isLinux) {

    if(bIsAndroid) return "Android";

    else return "Linux";

    }

    if (isWin) {

        var isWin2K = sUserAgent.indexOf("Windows NT 5.0") > -1 || sUserAgent.indexOf("Windows 2000") > -1;

    if (isWin2K) return "Win2000";

    var isWinXP = sUserAgent.indexOf("Windows NT 5.1") > -1 ||

    sUserAgent.indexOf("Windows XP") > -1;

    if (isWinXP) return "WinXP";

    var isWin2003 = sUserAgent.indexOf("Windows NT 5.2") > -1 || sUserAgent.indexOf("Windows 2003") > -1;

    if (isWin2003) return "Win2003";

    var isWinVista= sUserAgent.indexOf("Windows NT 6.0") > -1 || sUserAgent.indexOf("Windows Vista") > -1;

    if (isWinVista) return "WinVista";

    var isWin7 = sUserAgent.indexOf("Windows NT 6.1") > -1 || sUserAgent.indexOf("Windows 7") > -1;

    if (isWin7) return "Win7";

    var isWin8 = sUserAgent.indexOf("Windows NT 6.2") > -1 || sUserAgent.indexOf("Windows 8") > -1;

    if (isWin8) return "Win8";

    var isWin9 = sUserAgent.indexOf("Windows NT 6.3") > -1 || sUserAgent.indexOf("Windows 9") > -1;

    if (isWin9) return "Win8.1";

    }

    return "other";

}

document.writeln("您的操作系统是：" + detectOS());

alert(detectOS());
