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"></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: '',
                    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[];
             //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>
