isFormValid

Description

This store emits a single boolean value any time the form validity changes. The state is checked on every value change, and if there are no invalid fields it's set to true, otherwise false (which is the default).

Example

<script>

import { formula } from 'svelte-formula';

const { form, isFormValid } = formula();

</script>

<form use:form>

<label for='password'>Password</label>

<input type='password' required id='password' name='password' />

<label for='passwordMatch'>Password Match</label>

<input type='password' required id='passwordMatch' name='passwordMatch' />

<button disabled={!$isFormValid}>Submit</button>

</form>
