Vue 3: implementing v-model and Form Validation When Using Custom Validation Logic
I'm not sure how to approach I've been struggling with this for a few days now and could really use some help. I'm dealing with I'm relatively new to this, so bear with me... I'm working on a Vue 3 application where I'm using `v-model` to bind form inputs to a data object, but I'm running into issues with custom validation logic that I've implemented. Specifically, I'm trying to validate an email field and a password field, but when the validation fails, the form doesn't retain the input values correctly. I've tried using `watch` to monitor changes in the input fields, but it seems like the validation is resetting the form state, and I'm seeing the following warning in the console: `want to read properties of undefined (reading 'value')`. Here’s a simplified version of my component: ```javascript <template> <form @submit.prevent="handleSubmit"> <input v-model="form.email" type="email" placeholder="Email" /> <div v-if="errors.email">{{ errors.email }}</div> <input v-model="form.password" type="password" placeholder="Password" /> <div v-if="errors.password">{{ errors.password }}</div> <button type="submit">Submit</button> </form> </template> <script> export default { data() { return { form: { email: '', password: '' }, errors: {} }; }, methods: { validateForm() { this.errors = {}; if (!this.form.email.includes('@')) { this.errors.email = 'Invalid email.'; } if (this.form.password.length < 6) { this.errors.password = 'Password must be at least 6 characters.'; } return Object.keys(this.errors).length === 0; }, handleSubmit() { if (this.validateForm()) { // Submit the form } } } }; </script> ``` I’ve confirmed that the `validateForm` method is being called, but the question arises when there are validation errors. The inputs seem to lose their bound values, and I have to re-enter them after each validation failure. I suspect it might be related to how Vue handles reactivity or perhaps how I’m managing the errors object. Any insights into why this might be happening or how to keep the values intact would be appreciated! This is part of a larger application I'm building. Any advice would be much appreciated. The project is a microservice built with Javascript. Any pointers in the right direction?
