Answer and Explanation
To reset a form using Yup in Vue.js, you'll primarily need to manage both the form's data and the associated Yup validation schema. Here’s how you can achieve this effectively:
1. Set up your Form with Vue and Yup:
- First, ensure you have a reactive data object that represents your form's fields. Also, define a Yup schema for validation. Example:
<script setup>
import { reactive } from 'vue';
import as yup from 'yup';
const form = reactive({
name: '',
email: '',
age: null,
});
const schema = yup.object({
name: yup.string().required('Name is required'),
email: yup.string().email('Invalid email').required('Email is required'),
age: yup.number().integer().positive('Age must be a positive integer').nullable(),
});
</script>
2. Create a Reset Function:
- Create a method that resets the reactive form data to its initial state. This will clear any input values. For Yup, it's advisable to also clear or reset any form errors if you're displaying them.
3. Implement the Reset Logic:
- Here's how to create a reset method in your Vue component using the Composition API:
<script setup>
import { reactive, ref } from 'vue';
import as yup from 'yup';
const form = reactive({
name: '',
email: '',
age: null,
});
const schema = yup.object({
name: yup.string().required('Name is required'),
email: yup.string().email('Invalid email').required('Email is required'),
age: yup.number().integer().positive('Age must be a positive integer').nullable(),
});
const formErrors = ref({});
const resetForm = () => {
form.name = '';
form.email = '';
form.age = null;
formErrors.value = {}; // Clear error state as well
};
</script>
4. Using `resetForm` method:
- You can call the `resetForm` function on a button click event. Example in template:
<template>
<form @submit.prevent="handleSubmit">
<input v-model="form.name" type="text" placeholder="Name" />
<div v-if="formErrors.name">{{ formErrors.name }}</div>
<input v-model="form.email" type="email" placeholder="Email" />
<div v-if="formErrors.email">{{ formErrors.email }}</div>
<input v-model="form.age" type="number" placeholder="Age" />
<div v-if="formErrors.age">{{ formErrors.age }}</div>
<button type="submit">Submit</button>
<button type="button" @click="resetForm">Reset</button>
</form>
</template>
By using this method, the form data is cleared back to its original empty state, and, if you were displaying errors via `formErrors`, those are cleared as well, providing a clean, reset form ready for new inputs.
