Trigger a function upon the Vue 3 page (component) being loaded

Is there a way to trigger a function upon the loading of a specific component in Vue 3? I have a function exported from a .js file that needs to be executed when a particular component is displayed on the UI. Currently, I am using <script setup> within my components.

<script setup>
// Example
import { someFunction } from "./js/allowFunctions.js"
</script>

I attempted switching from <script setup> to just <script>, but refactoring a large amount of code in my project could be time-consuming.

Answer №1

If you need to run a function in your component immediately upon loading, utilize the lifecycle hook onMounted and place your function call inside it.

Here is an example:

<script setup>
import { onMounted } from "vue"
import { someFunction } from "./js/allowFunctions.js"

onMounted(() => {
  someFunction()
})
</script>
