一个段小代码。同一个站点针对移动端查看和电脑端查看跳转不同的页面。

首先载入jQuery文件。

$(function(){
    var MobileUA = (function() {
        var ua = navigator.userAgent.toLowerCase();

        var mua = {
            IOS: /ipod|iphone|ipad/.test(ua), //iOS
            IPHONE: /iphone/.test(ua), //iPhone
            IPAD: /ipad/.test(ua), //iPad
            ANDROID: /android/.test(ua), //Android Device
            WINDOWS: /windows/.test(ua), //Windows Device
            TOUCH_DEVICE: ('ontouchstart' in window) || /touch/.test(ua), //Touch Device
            MOBILE: /mobile/.test(ua), //Mobile Device (iPad)
            ANDROID_TABLET: false, //Android Tablet
            WINDOWS_TABLET: false, //Windows Tablet
            TABLET: false, //Tablet (iPad, Android, Windows)
            SMART_PHONE: false //Smart Phone (iPhone, Android)
        };

        mua.ANDROID_TABLET = mua.ANDROID && !mua.MOBILE;
        mua.WINDOWS_TABLET = mua.WINDOWS && /tablet/.test(ua);
        mua.TABLET = mua.IPAD || mua.ANDROID_TABLET || mua.WINDOWS_TABLET;
        mua.SMART_PHONE = mua.MOBILE && !mua.TABLET;

        return mua;
    }());

    //SmartPhone 
    if (MobileUA.SMART_PHONE) {
        // 移动端链接地址
