Vue 3 Form Submission optimization guide with Vuelidate - Validation Errors Not Displaying
I'm dealing with I'm sure I'm missing something obvious here, but I am working on a Vue 3 application using Vuelidate for form validation, but I'm running into issues where the validation errors aren't displaying as expected during form submission. I have set up my form and validation rules, but when I try to submit the form, no behavior messages show up, even when required fields are left empty. Here is my code snippet for the form and validation setup: ```javascript <template> <form @submit.prevent="submitForm"> <div> <label for="username">Username:</label> <input type="text" v-model="form.username" id="username" /> <span v-if="!$v.form.username.$pending && !$v.form.username.$model">Username is required</span> </div> <div> <label for="email">Email:</label> <input type="email" v-model="form.email" id="email" /> <span v-if="!$v.form.email.$pending && !$v.form.email.$model">Email is required</span> </div> <button type="submit">Submit</button> </form> </template> <script> import { required } from '@vuelidate/validators'; import useVuelidate from '@vuelidate/core'; export default { data() { return { form: { username: '', email: '' } }; }, validations() { return { form: { username: { required }, email: { required } } }; }, setup() { const v$ = useVuelidate(); return { v$ }; }, methods: { submitForm() { this.$v.$touch(); if (this.$v.$invalid) { console.log('Form is invalid'); return; } console.log('Form submitted successfully'); } } }; </script> ``` I have confirmed that Vuelidate is properly set up in my project, and I can see the validation state in the console. However, when I leave the fields empty and try to submit, the `submitForm` method logs 'Form is invalid', but the behavior messages aren't being displayed on the UI. I expected to see the 'Username is required' and 'Email is required' messages, but they don't show up. I also tried ensuring that the behavior spans are conditional on the `$pending` state and the model value, but that didn’t resolve the scenario. Has anyone encountered this scenario or can provide insight into why the validation messages aren't being rendered correctly? Any help would be greatly appreciated! My development environment is Ubuntu. Any help would be greatly appreciated! I've been using Javascript for about a year now. Is there a simpler solution I'm overlooking?
