VueRouter应用方法详解

<script>
import About from "./components/About.vue";
import Home from "./components/Home.vue";
import NotFound from "./components/Not Found.vue";
const routes = {
  //路由默认跳转到Home组件
  '/': Home,
  '/about': About
}
export default {
  data() {
    return {
      currentPath: window.location.hash
    }
  },
  computed: {
    //计算属性的方法，响应式的，缓存
    currentView() {
      //过滤#，匹配路由
      return routes[this.currentPath.slice(1) || '/' ] || NotFound
    }
  },
  mounted() {
    window.addEventListener('hashchange', () => {
      //只要window变化了就，把当前的路径给App组件下的属性this.currentPath
      this.currentPath = window.location.hash
    })
  }
}
</script>
