clearError

Clears all the errors from the form or the error from a field programmatically.

Demo

Usage

Validating/Invalidating the form without a field scoped validation

vue

<template>
    <form>
        <input type="text" v-bind="register('name')" />
        <input type="text" v-bind="register('email')" />
        <input type="text" v-bind="register('password')" />
        <input type="text" v-bind="register('password_confirmation')" />
        <button type="submit">Submit</button>
    </form>
</template>
<script setup lang="ts" >
import { useFormHandler, Interceptor } from 'vue-form-handler'

const sleep = (milliseconds: number) => {
    return new Promise(resolve => setTimeout(resolve, milliseconds))
}

//validate your fields here
const validateFieldGroup = async () => {
    await sleep(1000)
    return Math.random() < 0.5;
}

const interceptor: Interceptor = async ({ name, setError, clearError }) => {
    if (['name', 'email'].includes(name)) {
        await validateUser()
            ? clearError(name)
            : setError('user', 'User already exists')
    }
    return true
}

const { register } = useFormHandler({ interceptor })
</script>

Notice how we use the combination of setError and clearError in order to invalidate the form when we have some fields that need to be validated together and the error is not scoped to one single field but to the whole field group.

Clearing the errors of a form after triggering validation/ submitting on demand

vue

<template>
    <form @submit.prevent="handleSubmit(successFn, errorFn)">
        <input type="text" v-bind="register('name', {
            required: true
        })" />
        <p v-if="formState.errors.name"> {{ formState.errors.name }} </p>
        <input type="text" v-bind="register('email', {
            required: true
        })" />
        <p v-if="formState.errors.email"> {{ formState.errors.email }} </p>
        <input type="text" v-bind="register('summary')">
        <button type="submit">Submit</button>
    </form>
</template>
<script setup lang="ts" >
import { useFormHandler } from 'vue-form-handler'
import { watch } from 'vue'

let hasErrorsAfterSubmit = false;
const successFn = (form: any) => { console.log({ form }) }
const errorFn = () => { hasErrorsAfterSubmit = true }


const { register, handleSubmit, values, clearError, formState } = useFormHandler()

watch(
    () => values,
    () => {
        if (hasErrorsAfterSubmit) {
            clearError();
            hasErrorsAfterSubmit = false
        }
    },
    { deep: true })
</script>
