Sending data from a parent component to a child component through a function

Sending data from a parent component to a child component through a function

In the process of developing an app, I have implemented a feature where users must select options from four dropdown menus. Upon clicking the "OK" button, I aim to send all the selections to a child component for chart creation. Initially, I passed the selections as props and handled the computation within the child component like this:

<ChildComponent :name="name" :email="email" :date="date"></ChildComponent>

Now, my goal is to add a button that, when clicked, will trigger the same action of updating the props and sending them to the child component.

javascript vue.js prop

Answer №1

To update the props passed to a child component, simply create a method that updates their values.

<script setup>
const name = ref('')
const email = ref('')
const date = ref('')

function handleUpdate() {
  name.value = /* ... */
  email.value = /* ... */
  date.value = /* ... */
}
</script>

<template>
  <ChildComponent :name="name" :email="email" :date="date" />
  <button @click="handleUpdate">OK</button>
</template>

It may be worth considering using a form to group these values if you have multiple selects. This can make it easier to manage and pass them together.
