Issue with element failing to respond to data updates - v-if condition not functioning

I'm a beginner with Vue.js and I've written some code to toggle the heading when clicking the "toggle heading" button. However, for some reason it's not working as expected. I would really appreciate your help.

<script setup>
let show_heading=true;
function toggleHeading(){
  show_heading^=true;
}
</script>

<template>
  <h1 v-if="show_heading">Hello world is working</h1>
  <button class="btn btn-primary" @click="toggleHeading">Toggle heading</button>
</template>

<style scoped>

</style>

Answer №1

Here is a sample script setup section for you to try out:

import { reactive } from 'vue';

const show_message = reactive({
  isVisible: true
});

function toggleMessageVisibility() {
  show_message.isVisible = !show_message.isVisible;
}
