[Vuejs]-Problems with validation before submit

✅

Each input needs to be wrapped in a ValidationProvider. Change this:

<input type="text" rules="required">

To this:

<ValidationProvider rules="required">
    <input type="text" rules="required" v-model="something">
</ValidationProvider>

Additionally, somewhere, you need to actually define the rules you want to use, so at the top of the file I put this:

import { ValidationObserver, ValidationProvider, extend } from "vee-validate";
import { required } from 'vee-validate/dist/rules';

extend('required',required);

Working copy of your Code Sandbox (I also updated vee-validate and vue to the latest versions): https://codesandbox.io/s/vue-template-dj9jn

To actually get the behaviour mentioned in the example, instead of using the invalid flag of ValidationObserver, try using the handleSubmit method like so:

<ValidationObserver tag="form" v-slot="{handleSubmit}" @submit.prevent>
  ... 
  <button @click="handleSubmit(submit)">Submit</button>

And your submit function would look like this:

submit() {
    //anything you do here will only be called when the form is valid
}
