title: Vue js : How to get specific route parameter in url
body: <p>I have a nested route settings</p>
  
  <pre><code>let routes = [
  {
      name: 'Admin',
      path: '/prod/:id',
      component: Admin,
      meta: {
          requiresAuth: true,
          title: 'Admin - Fraud tool'
      },
      children:[
          {
              path: 'users',
              component: Users
          }
      ]
  }];
  </code></pre>
  
  <p>Then my url looks like this</p>
  
  <pre><code>http://localhost/prod/admin/users
  </code></pre>
  
  <p>How can I get the <code>admin</code> in this route in vue js?</p>
