JS获取设备信息

获取设备相关信息：

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 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;
