Yesterday I started working with Vue and have already learned quite a bit. Now I have seen, you can toggle classes directly on the HTML object via the @click event.
Unfortunately, I do not really succeed. With Blank Javascript no problem, but I want to implement this with Vue.
<li @click=" show = !show" :class="{ active: show }" class="nav-item dropdown">
setup() {
const show = false
return { show };
},
In this is "show" the class which i want to toggle.
This may be working fine
<script>
import { ref } from 'vue'
export default {
setup() {
const show = ref(false)
return { show }
}
}
</script>
<template>
<li @click="show = !show" :class="{ active: show }" class="nav-item dropdown">toggle me</li>
</template>
<style>
.active {
background-color: red;
}
</style>
This is also a valid syntax btw
<script setup>
import { ref } from 'vue'
const show = ref(false)
</script>
You can also use :class="show && 'active'" if you prefer to not have to invert/think of the actual order every-time (personal preference, exactly the same at the end).
