    </div>
    <!-- tab内容 -->
    <keep-alive>   
      <component v-bind:is="tabView, tabChange(radio)" style="background: #FF0000; width: 100%; height: 100%"></component>  
    </keep-alive>

<script>  
  import select1 from './components/xxx1.vue';

export default {  
  name: 'app',  
  data () {  
    return {  
      radio: '代码仓库',
      tabView: 'select1',
    }
