Swapping out getElementByID for refs in Vue 3 is not effective

My Current Vue Dilemma

I am a newcomer to Vue and I'm attempting to swap out the use of getElementByID with $refs, but I keep encountering the following error:

The Issues I'm Facing

Show Me the Code!

Below is the HTML snippet in question:

<router-link to="/" ref="navOpt">
    <div ref="activeOpt">

And this is the accompanying script:

// imports
import { ref, onMounted } from "vue";

// setup
setup() {
  let navOpt = ref();
  let activeOpt = ref();
  onMounted(() => this.$refs.navOpt);
  onMounted(() => this.$refs.activeOpt);
  return { navOpt, activeOpt };
},

// Methods - checking if the navOpt is active and removing css accordingly
checkActiveRoute() {
  if (this.navOpt.classList.contains("router-link-active")) {
    this.activeOpt.classList.remove("hide-active");
  }
},

// Created - calling method on page load
created() {
  this.checkActiveRoute();
},

Possible Solutions I've Explored

I have attempted implementing a solution found here, but unfortunately, it led to the same persistent error.

If anyone could offer assistance with this issue, I would greatly appreciate it! Thank you in advance!

Answer №1

ref values are automatically linked to the ref attribute in HTML elements without needing to explicitly call

onMounted(() => this.$refs.navOpt)
. It is recommended to choose either the composition API or options API, with a preference for the composition API. Define methods as standalone functions and call them within the onMounted hook:

setup() {
  let navOpt = ref();
  let activeOpt = ref();
  onMounted(() => {
     checkActiveRoute()
   });

function checkActiveRoute() {
  if (navOpt.value.classList.contains("router-link-active")) {
        activeOpt.value.classList.remove("hide-active");
  }
}
  return { navOpt, activeOpt };
},
