Vue 3: implementing Dynamic Form Fields Not Retaining State After Validation Errors
I'm following best practices but I tried several approaches but none seem to work. I'm working with Vue 3 to create a dynamic form where users can add or remove fields as needed. However, I'm working with a frustrating scenario where the dynamically generated fields lose their state when validation fails. I'm using VeeValidate for form validation and Vue's reactive properties for the form data. Here’s a simplified version of my code: ```javascript <template> <form @submit.prevent="submitForm"> <div v-for="(field, index) in fields" :key="index"> <input v-model="field.value" :name="`field-${index}`" /> <span v-if="errors[`field-${index}`]">{{ errors[`field-${index}`] }}</span> <button type="button" @click="removeField(index)">Remove</button> </div> <button type="button" @click="addField">Add Field</button> <button type="submit">Submit</button> </form> </template> <script> import { ref } from 'vue'; import { useForm } from 'vee-validate'; export default { setup() { const { errors, validate } = useForm(); const fields = ref([{ value: '' }]); const addField = () => { fields.value.push({ value: '' }); }; const removeField = (index) => { fields.value.splice(index, 1); }; const submitForm = async () => { const result = await validate(); if (!result) return; // Validation fails, but fields lose their input // Handle form submission }; return { fields, addField, removeField, submitForm, errors }; }, }; ``` In this example, if the user leaves any field empty and tries to submit the form, the validation fails, and the fields are reset to their initial state. I’ve tried setting up the fields as reactive properties and even looked into using `v-model` with an array of objects, but the scenario continues. The expected behavior is that the input values should continue even after validation errors, so users don’t have to re-enter them. Has anyone else encountered this question, and if so, how did you resolve it? Any insights on managing dynamic fields with validation in Vue would be greatly appreciated! I'm working on a web app that needs to handle this. Has anyone else encountered this? I appreciate any insights!
