再顺便总结下Vue中路由的几个关键点吧：
1：需要引入<script type="text/javascript" src="js/vue-router.js"></script>，都组件化开发了，Vue中是没有vue-router的，已经把它拎出来了，
2：需要指明路由存放的位置<router-view>This is contents</router-view>
3：路由的定义：const router=new VueRouter({routes});当把routes（const routes=[]）拎出去写的时候要把它写在定义语句的前面
4: 路由中用到的一些方法：$route.params()/$route.path()/$route.query()/router.push({pach:'路径'})/router.replace({pach:'路径'})/router.go(1/-1):跳转到前一页/后一页
