Vue 3 Form Validation scenarios with v-model on Nested Objects in Reactive State
I need help solving I'm experimenting with I'm implementing a form in Vue 3 where I need to validate a nested object structure in my reactive state... I have a form that allows users to input their address, which includes a nested object for 'street', 'city', and 'zip'. However, when I try to validate the form, I'm getting unexpected results. For example, the form sometimes shows a validation behavior for 'city' even when it's filled out correctly. I've set up v-model binding on my input fields, but I suspect the scenario lies in how I'm handling the reactive state. Here’s a simplified version of my code: ```javascript <template> <form @submit.prevent="submitForm"> <div> <label for="street">Street:</label> <input v-model="form.address.street" id="street" type="text" required /> </div> <div> <label for="city">City:</label> <input v-model="form.address.city" id="city" type="text" required /> <span v-if="errors.city">{{ errors.city }}</span> </div> <div> <label for="zip">ZIP Code:</label> <input v-model="form.address.zip" id="zip" type="text" required /> </div> <button type="submit">Submit</button> </form> </template> <script> import { reactive } from 'vue'; export default { setup() { const form = reactive({ address: { street: '', city: '', zip: '', }, }); const errors = reactive({ city: '', }); function submitForm() { if (!form.address.city) { errors.city = 'City is required'; } else { errors.city = ''; } // Other validation... } return { form, errors, submitForm }; }, }; ``` I've tried using `console.log` to debug the values of `form.address` and `errors`, and they seem to be updating correctly on input change. However, when I submit the form, the validation doesn't always trigger as expected. Sometimes the `city` field even gets marked as invalid randomly. I'm using Vue 3.0.0, and I wonder if this behavior is due to how Vue handles reactivity in nested objects. Could someone guide to understand why this validation is not working as intended, and what best practices I can follow to ensure accurate validation? Any insights would be greatly appreciated! For context: I'm using Javascript on macOS. Any ideas what could be causing this? I'm working in a CentOS environment. The project is a desktop app built with Javascript.
