首先是html代碼：

 <nav class="mui-bar mui-bar-tab">
                    <a href="view/templates/home/home.html" class="mui-tab-item mui-active" id="defaultTab">
                        <span class="mui-icon iconfont icon-shouye"></span>
                        <span class="mui-tab-label
 
">首頁</span>
                    </a>
                    <a href="view/templates/ShopClass/ShopClass.html" class="mui-tab-item">
                        <span class="mui-icon iconfont icon-shop"></span>
                        <span class="mui-tab-label">商城</span>
                    </a>
                    <a href="
 
view/templates/ShopCart/ShopCart.html" class="mui-tab-item">
                        <span class="mui-icon iconfont icon-gouwuche"><span class="mui-badge">5</span></span>
                        <span class="mui-tab-label">購物車</span>
                    </a>
                    <a href="
 
view/templates/person/person.html" class="mui-tab-item">
                        <span class="mui-icon iconfont icon-wode"></span>
                        <span class="mui-tab-label">我的</span>
                    </a>
                </nav>

js引用別忘了，引用MUI的js文件

下面是js代碼：

 <script type="text/javascript">
        
    //啟用雙擊監聽
        mui.init({
            gestureConfig:{
                doubletap:true
            },
            subpages:[{
                url:‘view/templates/home/home.html‘,
                id:‘MainViwe‘,
                styles:{
                    top: ‘0‘,
                    bottom: ‘51px‘
                }
            }]
        });
    
    mui(‘.mui-scroll-wrapper‘).scroll({
        deceleration: 0.0005 //flick 減速系數，系數越大，滾動速度越慢，滾動距離越小，默認值0.0006
    });

//底部選項卡切換跳轉
(function jumpPage(){
        //跳轉頁面
        var subpages = [‘view/templates/home/home.html‘,‘view/templates/ShopClass/ShopClass.html‘, ‘view/templates/ShopCart/ShopCart.html‘, ‘view/templates/person/person.html‘];
        var subpage_style = {
            top: ‘44px‘,
            bottom: ‘51px‘
        };
        var aniShow = {};//動畫顯示
        //首次啟動切滑效果
             //當前激活選項
            var activeTab = subpages[0];         
             //選項卡點擊事件
            mui(‘.mui-bar-tab‘).on(‘tap‘, ‘a‘, function(e) {
                var targetTab = this.getAttribute(‘href‘);
                $(‘#MainViwe‘).attr(‘src‘,targetTab);
            });
             //自定義事件，模擬點擊“首頁選項卡”
            document.addEventListener(‘gohome‘, function() {
                var defaultTab = document.getElementById("defaultTab");
                //模擬首頁點擊
                mui.trigger(defaultTab, ‘tap‘);
                //切換選項卡高亮
                var current = document.querySelector(".mui-bar-tab>.mui-tab-item.mui-active");
                if (defaultTab !== current) {
                    current.classList.remove(‘mui-active‘);
                    defaultTab.classList.add(‘mui-active‘);
                }

    });
   

        })()

    </script>
