models.blade.php

{!! Form::open(['route' => 'customer.register', 'id' => 'registerForm', 'novalidate']) !!}
        <input name="email" data-error="Oops!!, that email address is invalid" class="form-control input-lg flat" placeholder="{{ trans('theme.placeholder.your_email') }}" type="email" pattern=".*@\w{2,}\.\w{2,}" required  data-emailexist data-emailexist-error="Email Already Exist" />
        {!! Form::close() !!}

appjs.blade.php

<script type="text/javascript">
"use strict";

;(function($, window, document) {
    $(document).ready(function(){
        $.ajaxSetup ({
            cache: false,
            headers: {
                'X-CSRF-TOKEN': "{{ csrf_token() }}"
            }
        });



    var _token = $('input[name="_token"]').val();
                    var filter = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
                    if(filter.test(email))
                    {
                        $.ajax({
                            url:"{{ route('email_available.check') }}",
                            method:"POST",
                            data:{email:email, _token:_token},
                            success:function(result)
                            {
                                if(result == 'unique')
                                {
                                    return true;
                                }
                                else
                                {
                                    return false;
                                }
                            }
                        });
                    }
