使用 CRUD 设置激活具有多级嵌套路由的路由器链接

Question

我尝试像下面那样设置深度嵌套，我有点确定我们不能在 router-link 中使用 exact 来进行嵌套路由。

<div id="app">
  <nav class="nav nav-main">
    <router-link exact to="/" class="nav-link" activeClass="active">Dashboard</router-link>
    <router-link to="/projects" class="nav-link" activeClass="active">Projects</router-link>
  </nav>

  <div class="parent-content">
    <h4>Content for Parent goes here</h4>
  </div>

  <router-view>
    <nav class="nav nav-main">
      <router-link :to="'/projects/' + $route.params.projectId" class="nav-link" activeClass="active">Deals</router-link>
      <router-link :to="'/projects/' + $route.params.projectId + '/commitments/'" class="nav-link" activeClass="active">Commitments</router-link>
    </nav>
    <router-view>
      <div class="child-content">
        <h4>Content for Child goes here</h4>
      </div>
    </router-view>
  </router-view>
</div>

我的路线：

routes: [
  {
    path: '/',
    component: Dashboard
  },
  {
    path: '/projects',
    component: Projects
  },
  {
    path: '/projects/:id',
    name: 'projects-detail',
    component: ProjectDetails,
    children: [
      // DEALS
      {
        path: '/projects/:projectId/deals',
        component: Deals
      },
      {
        path: '/projects/:projectId/deals/:dealId/details',
        component: DealDetails
      },
      // COMMITMENTS
      {
        path: '/projects/:projectId/deals/:dealId/commitments/:commitmentId/edit',
        component: CommitmentEdit
      }
    ]
  }
]

通过上述设置，我需要激活路由器链接，当路由是：
/projects/:projectId/deals/:dealId/details 然后激活Deals
/projects/:projectId/deals/:dealId/commitments/:commitmentId/edit 然后激活Commitments

我认为您在ProjectDetails 组件中没有另一个<router-view></router-view> 添加这个并尝试。

同时从所有子路径中删除 /projects/:projectId，因为您已经在父路径中删除 path: '/projects/:id',

所以最后你的路线是

routes: [
  {
    path: '/',
    component: Dashboard
  },
  {
    path: '/projects',
    component: Projects
  },
  {
    path: '/projects/:id',
    component: ProjectDetails,
    children : [
      // DEALS
      {
        path: 'deals/:dealId/details',//path will be /projects/:projectId/deals/:dealId/details
        component: DealDetails
      },
      {
        path: 'deals',.// path will be /projects/:projectId/deals
        component: Deals
      },
      // COMMITMENTS
      {
        path: '/deals/:dealId/commitments/:commitmentId/edit/',
        component: CommitmentEdit
      }
    ]
  }
]

如果您不需要并且组件依赖于父级，请不要将其作为子级直接用作根路径，如

routes: [
  {
    path: '/',
    component: Dashboard
  },
  {
    path: '/projects',
    component: Projects
  },
  {
    path: '/projects/:id',
    component: ProjectDetails,
   },
    // DEALS
    {
      path: '/projects/:projectId/deals/:dealId/details',
      component: DealDetails
    },
    {
      path: '/projects/:projectId/deals',
      component: Deals
    },
    // COMMITMENTS
    {
      path: '/projects/:projectId/deals/:dealId/commitments/:commitmentId/edit/',
      component: CommitmentEdit
    }
]

router-link-exact-active 类已在此示例中工作：https://jsfiddle.net/chyLjpv0/18/ 将链接显示为活动

在您的编辑中

为什么你把<router-view> 放在<router-view> 里面。外部仅在被替换时才起作用，而内部<router-view> 毫无价值。子组件在父组件中使用<router-view>。

您的内部<router-view> 也没有像</router-view> 那样正确关闭
