模板样式
<template>
  <div id="app">
    <router-view/>
    <nav class="mui-bar mui-bar-tab">
        <a class="mui-tab-item mui-active" href="/">
            <span class="mui-icon mui-icon-home"></span>
            <span class="mui-tab-label">运动</span>
        </a>
        <a class="mui-tab-item" href="/">
            <span class="mui-icon mui-icon-email"></span>
            <span class="mui-tab-label">发现</span>
        </a>
        <a class="mui-tab-item" href="/community">
            <span class="mui-icon mui-icon-contact"></span>
            <span class="mui-tab-label">社区</span>
        </a>
        <a class="mui-tab-item" href="/home">
            <span class="mui-icon mui-icon-gear"></span>
            <span class="mui-tab-label">我</span> 
        </a>
    </nav>
  </div>
</template>

在js配置tap事件，使用路由跳转
    var _this = this;
    this.Mui('.mui-bar-tab').on('tap', 'a', function(e) {
      var path= this.getAttribute('href');
         _this.$router.push(path)
     })
