vue中有多个router-view 时，哪个view 显示你要显示的组件呢

1、给router-view取个名字：

<router-view name = "view_home"/>

2、在index.js中这样写

export default new Router({
  routes: [
    {
      path: '/',
      redirect: 'HomePage'
    },
    {
      path: '/HomePage',
      name: 'HomePage',
      components: {
        view_home: HomePage
      }
    }
  ],
  mode:'history'
})

to到对应path的时候在components属性中按name属性确定要更新的router-view
