Vue 2, how to use a prop as the class name
Sometimes you pass a prop to a component, and you want to use that prop value as the class name. How to do that?
Say you have a Car component.
You want to add a class to its output based on a prop.
So maybe the prop is called color
, and you use it like this in other parts of the app:
<Car color="red">
<Car color="blue">
In your Car component you first need to declare the color prop:
<script>
export default {
name: 'Car',
props: {
color: String
}
}
</script>
then you can use it in the template part:
<template>
<div :class="color"></div>
</template>
If you want to add a car
class, plus the class determined by the color prop, you can use this syntax:
<template>
<div :class="['car', color]"></div>
</template>
Happy coding!
