To effectively manage the state of your application, it is advisable to utilize a framework such as Vue rather than directly targeting DOM elements. By doing so, you can easily verify and accommodate reactive changes within your app.
If you are new to Vue, I suggest delving deeper into its functionalities. One fundamental concept to grasp is:
Parent to child communication:
In this form of communication, data is passed from a parent component to a child component through props defined in the component declaration.
<template>
<div>
<Car color="green" />
</div>
</template>
It's important to note that props flow only in one direction: from parent to child. Whenever the value of a prop is updated by the parent, the change is propagated to the child for re-rendering.
Conversely, changing a prop within the child component is discouraged.
Child to parent communication:
In this scenario, communication from child to parent is facilitated through events.
<script>
export default {
name: 'Car',
methods: {
handleClick: function() {
this.$emit('clickedSomething')
}
}
}
</script>
The parent component can capture these events using the v-on directive when including the child component in its template:
<template>
<div>
<Car v-on:clickedSomething="handleClickInParent" />
<!-- or -->
<Car @clickedSomething="handleClickInParent" />
</div>
</template>
<script>
export default {
name: 'App',
methods: {
handleClickInParent: function() {
//...
}
}
}
</script>
By adhering to these principles, you can dynamically render components based on specific conditions using directives like v-if:
<h1 v-if="showHeader">Show your header</h1>
<h1 v-else>Show something else</h1>
With this approach, you have the flexibility to toggle elements as needed throughout your application.
