Question

我有一个“文档”页面，其中包含3个子菜单。

无论单击哪个子菜单，我都想做的是，我希望它转到一个主文档Vue组件，然后将一个变量传递给它，这样子组件也将加载到主组件中。 / p>

这是我到目前为止所拥有的：

导航

      <div>
          <nav class="navbar navbar-expand-lg">

                }, 1)
            }

routes.js

import Home from './components/Home.vue';
import ContactUs from './components/ContactUs';
import Documentation from './components/DocumentationMain';

export const routes = [
    { path: '', component: Home },
    { path: '/contactus', component: ContactUs },
    { path: '/documentation', component: Documentation, props: true },
    { path: '*', redirect: '/' }
];

给予

问题

有没有更简便的方法？
当我单击菜单时，我的'DocumenationMain'似乎没有注册VueEvent.$emit
当我第二次单击链接时，将呈现正确的组件
当我单击链接时，我所有其他菜单都突出显示为蓝色

我感觉自己做错了

只需使用Dynamic Route Matching

export const routes = [
    { path: '', component: Home },
    { path: '/contactus', component: ContactUs },
    { path: '/documentation/:doctype', component: Documentation, props: true },
    { path: '*', redirect: '/' }
];

nav.vue

<router-link to="/documentation/reseller" />
<router-link to="/documentation/cust" />
<router-link to="/documentation/admin" />

Documentation.vue

props: {
  doctype: {
    type: String,
    default: 'admin'
  }
}

路由器现在应该将:doctype值（来自URL）传递到文档组件doctype prop中-使用它来确定要在内部激活的子组件...

多个链接将参数传递到同一路由
