1.引入vue-router
2. router-link 标签 切换锚点值 一定要写to属性，不然报错
3. router-view 标签 切换组件的容器
4.初始化router路由对象
5.配置路径(锚点值与组件的对应关系)
6.在实例上挂载路由
如果有子路由，请往最后看！！！

// 4.初始化router路由对象
let router = new VueRouter({
// 5.配置路径(锚点值与组件的对应关系)
routes: [{
path: '/login',
component: login
}, {
path: '/reg',
component: reg
}, {
path: '/indexCom',

}, {
path: '/',
redirect: '/indexCom'
}]
})
const app = new Vue({
el: '#app',
data: {},
// 6.在实例上挂载路由
router: router
})
</script>
</body>
</html>
添加子路由：
最后附赠一个Vue-Router中常见的导航方式：
this.$router.push("hash地址");
this.$router.push("/login");
this.$router.push({ name:'user' , params: {id:123} });
this.$router.push({ path:"/login" });
this.$router.push({ path:"/login",query:{username:"jack"} });
this.$router.go( n );//n为数字，参考history.gothis.$router.go( -1 ); //用法类似于 history.go(-1)
