Javascript – Vue.js router.push changes URL but RankerDetail component doesn't update on button navigation

I’m developing a Vue.js application with vue-router and facing an issue with my RankerDetail component. This component is meant to display different data based on the route parameter id. When I manually enter the URLs (e.g., /Ranker/1, /Ranker/2) in the browser, the RankerDetail component correctly displays the respective data. However, when using navigateToNextCase() and navigateToPreviousCase() methods to navigate, the URL in the browser changes (from /Ranker/1 to /Ranker/2), but the component does not update to show the new case’s data.

This is how the router.js is configured:

const routes = [
    // Other routes...
    { path: '/Ranker/:id', name: 'RankerDetail', component: RankerDetail, props: true, meta: { requiresAuth: true } },
];

Here are the relevant route configurations and navigation methods:

function navigateToPreviousCase() {
  const currentId = parseInt(route.params.id);
  if (currentId > 1) {
    const previousId = currentId - 1;
    router.push({ name: 'RankerDetail', params: { id: previousId } });
  }
}

function navigateToNextCase() {
  const currentId = parseInt(route.params.id);
  const nextId = currentId + 1;
  router.push({ name: 'RankerDetail', params: { id: nextId } });
}

The issue seems to be with the view not re-rendering after the route parameter changes through the navigation buttons, even though the URL in the browser updates correctly. This problem does not occur when entering the URLs directly in the browser.

How can I ensure that the RankerDetail component refreshes and displays the correct data when navigating through the navigateToNextCase() and navigateToPreviousCase() methods? What might be causing the component to not react to the route parameter change when navigating via these methods?

    I was able to solve the problem by adding the key $route.fullPath to the <router-view>. In the the main component where <router-view> is used (in my case the App.vue), update the tag as follows:

    <router-view :key="$route.fullPath"></router-view>

    This modification forces Vue to treat each route as a unique instance, thus re-rendering the component whenever the route changes. The $route.fullPath ensures that the key is unique for each different path, triggering a re-render of the router-view and its child components, which in my case, will ensure that RankerDetail is properly reloaded and displays the updated content.

    Method 1 :

    You can use the watch function on the params passed in the router URL.

    The params can be checked using the router object [const router = useRouter()] as follow

    router.currentRoute.value.params.id

    When any change in param is occurred, update the values or call any API to update values as per your requirement.

    Method 2 :

    Not recommended

    You can use the JavaScript window object to reload the whole page after
    router.push() is called.

    window.reload()
