     <p v-if="errors.length" class="text-danger">
      <b>Please correct the following error(s):</b>
        <li v-for="error in errors" v-bind:key="error">{{ error }}</li>
    <div class="form-group">

    <button type="submit" class="btn btn-primary mb-3">Submit</button>
//Bootstrap library
import 'bootstrap/dist/css/bootstrap.min.css';

export default {
  data() {
    return {
     name: null,
     job_title: null,
     emailRules:/^\w+([.-]?\w+)*@\w+([.-]?\w+)*(\.\w{2,3})+$/ //Valid Email Match
  methods: {
    checkForm:function(e) {
      this.errors = [];
      if(! this.errors.push("Name required.");
      //Email validation for valid email address
      if(!this.emailRules.test( this.errors.push("Please Enter Correct Email.");
      if(!this.job_title) this.errors.push("Job Title required.");

      // Form reset after submit = = this.job_title = '';;
