<template>
   
      <h1>therichpost.com</h1>
      
    
   <div class="container" style="margin-top:30px">
   
    <form id="app"
    @submit="checkForm"
    action=""
    method="post">
     <p v-if="errors.length" class="text-danger">
      <b>Please correct the following error(s):</b>
      <ul>
        <li v-for="error in errors" v-bind:key="error">{{ error }}</li>
      </ul>
    </p>
    <div class="form-group">
        <label for="email">Email address:</label>
        <input type="text" class="form-control" placeholder="Enter email" id="email" v-model="email">
    </div>
    <div class="form-group">
        <label for="name">Username:</label>
        <input type="text" class="form-control" placeholder="Enter username" id="name" v-model="name">
    </div>

    <div class="form-group">
        <label for="jobtitle">Job Title:</label>
        <input type="text" class="form-control" placeholder="Enter job title" id="jobtitle" v-model="job_title">
    </div>
    
    <button type="submit" class="btn btn-primary mb-3">Submit</button>
    </form>
  </div>
 
</template>
<script>
//Bootstrap library
import 'bootstrap/dist/css/bootstrap.min.css';

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

      // Form reset after submit
      this.name = this.email = this.job_title = '';
       e.target.reset();
     
     
    }
  }
}
</script>
