Vue Router: How to Refresh the DOM When Navigating to the Same Route with Different Params?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm experiencing an issue where navigating to a route with parameters allows me to reference and update DOM elements (like refreshing them or adding new divs). However, if I navigate away and then back to the same route with different params, the DOM elements either are not workably referenced or still point to the elements from the first load. I've tried using forceUpdate and wrapping the component in keep-alive, but the problem persists.

Here is my current router configuration:

TYPESCRIPT
import { createRouter, createWebHistory } from '@ionic/vue-router';
import { RouteRecordRaw } from 'vue-router';
import SomePage from '@/views/SomePage.vue';

const routes: Array<RouteRecordRaw> = [
{
    path: '/some/:id',
    name: 'SomePage',
    component: SomePage
}
]

const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),
  routes
})

export default router

In my App, I watch for route changes to refresh or manipulate DOM elements as shown below:

JAVASCRIPT
watch:{
    $route (to, from){
      if(to.name == 'SomePage') {
         this.emitter.emit("addDatePickerToSomePage", {});
      }
    }
}

I need a solution that ensures the correct instance of the page (with the current params) is updated, rather than reusing the previous page's DOM elements. Any insights or workarounds would be appreciated.

When navigating between routes that use the same component (even if the params change), Vue reuses the same component instance. This can make it seem like the DOM isn’t updating because the component isn’t being recreated. To work around this, you have a few options:

1. Use a Unique Key on the Router View

By adding a unique key (for example, using $route.fullPath or $route.params.id) to the (or the component itself), you force Vue to treat each route change as a fresh instance, triggering a full refresh of the component:

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

Or, if you’re only interested in param changes:

HTML
<router-view :key="$route.params.id" />

2. Use the beforeRouteUpdate Hook

If you’d prefer to keep the same component instance (for caching or performance reasons), you can watch for changes in the route params within the component using the beforeRouteUpdate guard. Then use Vue’s nextTick to wait for the DOM to update before performing your DOM manipulations:

VUE
<script>
export default {
  name: 'SomePage',
  watch: {
    '$route.params.id'(newId, oldId) {
      // Wait for the DOM to update before manipulating it
      this.$nextTick(() => {
        this.emitter.emit("addDatePickerToSomePage");
      });
    }
  },
  beforeRouteUpdate(to, from, next) {
    // Optionally do any cleanup or initialization
    next();
  }
}
</script>

3. Lifecycle Hooks with keep-alive

If you are using , the component is cached and won’t be recreated on navigation. In that case, you can use the activated hook to perform DOM operations when the component is re-activated:

VUE
<script>
export default {
  name: 'SomePage',
  activated() {
    this.$nextTick(() => {
      this.emitter.emit("addDatePickerToSomePage");
    });
  }
}
</script>

Conclusion

Choose the approach that best fits your needs:

Use a dynamic key if you want the component to be recreated on every navigation.
Use beforeRouteUpdate or activated to handle changes in an already instantiated component.

These techniques help ensure that your DOM manipulations reference the current instance’s elements.

Ok so I was looking it up and when I use ref instead of like getelementbyid it did work.
