Vue.js vForm - JavaScript

Vue.js vForm is a type of component library that helps the user create form elements quickly and easily in a Vue.js app. It is based on the Bootstrap framework and provides built-in validators, error messages, and form handling capabilities.

Features

Some of the key features of Vue.js vForm are:

• Built-in validators: The library provides built-in validators such as email, required, size, min, and max. Users can also create their own custom validators.

• Error messages: When a user enters incorrect input, an error message appears dynamically, making the validation process more visible.

• Form handling: The library provides a way to handle forms with ease, including data submission, error handling, and custom form actions.

• Customizable styles: The library is based on the Bootstrap framework and allows customization of the form's look and feel.

How to Use

To use Vue.js vForm, you must first import it into your project.

import Vue from 'vue'
import { Form, HasError, AlertError } from 'vform'
Vue.component('form', Form)
Vue.component('has-error', HasError)
Vue.component('alert-error', AlertError)

After importing Vue.js vForm, you can create a new form in your Vue.js component and add fields to it using the following format:

<template>
  <form @submit.prevent="submit">
    <div class="form-group">
      <label for="name">Name</label>
      <input v-model="name" type="text" class="form-control" name="name">
      <has-error :form="form" field="name"></has-error>
    </div>
    <div class="form-group">
      <label for="email">Email</label>
      <input v-model="email" type="email" class="form-control" name="email">
      <has-error :form="form" field="email"></has-error>
    </div>
    <button type="submit" class="btn btn-primary">Submit</button>
  </form>
</template>

<script>
  export default {
    data() {
      return {
        name: '',
        email: '',
        form: new Form({
          name: '',
          email: '',
        })
      }
    },
    methods: {
      submit() {
        this.form.post('api/example').then(response => {
          // Handle response
        })
      }
    }
  }
</script>

In this code example, we see that the Vue.js vForm components are used to add validation and error messaging to the name and email fields of the form. The form data is handled with the Form object, which is initialized in the component's data function. Finally, the submit method is called when the form is submitted, and it sends the data to an API endpoint using a POST request.

Conclusion

Vue.js vForm is a powerful tool for building forms quickly and efficiently in a Vue.js app. It provides built-in validators, error messages, and form handling capabilities that can help streamline the development process. Additionally, the library is highly customizable, so developers can create forms with custom styles that match their app's look and feel.
