JS判断当前访问设备是手机/平板/电脑？

一、程序代码

<script>
        var os = function () {
            var ua = navigator.userAgent,
                isWindowsPhone = /(?:Windows Phone)/.test(ua),
                isSymbian = /(?:SymbianOS)/.test(ua) || isWindowsPhone,
                isAndroid = /(?:Android)/.test(ua),
                isFireFox = /(?:Firefox)/.test(ua),
                isChrome = /(?:Chrome|CriOS)/.test(ua),
                isTablet = /(?:iPad|PlayBook)/.test(ua) || (isAndroid && !/(?:Mobile)/.test(ua)) || (isFireFox &&
                    /(?:Tablet)/.test(ua)),
                isPhone = /(?:iPhone)/.test(ua) && !isTablet,
                isPc = !isPhone && !isAndroid && !isSymbian;
            return {
                isTablet: isTablet,
                isPhone: isPhone,
                isAndroid: isAndroid,
                isPc: isPc
            };
        }();
        console.log('os', os)
        if (os.isAndroid || os.isPhone) {
            // 手机
            window.location.href = "https://m.xxxx.com";
        } else if (os.isTablet) {
            // 平板
        } else if (os.isPc) {
            // 电脑
        }
    </script>
