MUI底部导航栏切换效果

首先是html代码：

 <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">首页</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">购物车</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引用别忘了，引用MUI的js文件

下面是js代码：

 <script type="text/javascript">
        
    //启用双击监听
        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 减速系数，系数越大，滚动速度越慢，滚动距离越小，默认值0.0006
    });

//底部选项卡切换跳转
(function jumpPage(){
        //跳转页面
        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 = {};//动画显示
        //首次启动切滑效果
             //当前激活选项
            var activeTab = subpages[0];         
             //选项卡点击事件
            mui(\'.mui-bar-tab\').on(\'tap\', \'a\', function(e) {
                var targetTab = this.getAttribute(\'href\');
                $(\'#MainViwe\').attr(\'src\',targetTab);
            });
             //自定义事件，模拟点击“首页选项卡”
            document.addEventListener(\'gohome\', function() {
                var defaultTab = document.getElementById("defaultTab");
                //模拟首页点击
                mui.trigger(defaultTab, \'tap\');
                //切换选项卡高亮
                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>
