javascript – 如何使用ajax在laravel 5中发布表单？

我在学习如何在laravel中制作一个ajax帖子时遇到了很多麻烦.我希望能够在验证后使用 jquery显示错误但我不知道如何访问发送到我的控制器的对象;所以我甚至不知道控制器中的“返回”是什么.有人可以带我走过这个吗？

这是我观点的一部分

<Meta name="_token" content="{{ csrf_token() }}" />            
<div class='row'>
        {!! Form::open(['url'=>'register','id'=>'sign-up','class'=>'col-md-6 col-md-push-4 form-horizontal'])!!}

            <div class='form-group'>
                {!! Form::label('first_name','First Name:',['class'=>'col-xs-12 col-md-3']) !!}
                <div class= 'col-xs-12 col-md-6'>
                    {!! Form::text('first_name',null,['class' => 'form-control'])!!}
                </div>
            </div>
            <div class='form-group'>
                {!! Form::label('last_name','Last Name:',['class'=>'col-xs-12 col-md-3']) !!}
                <div class= 'col-xs-12 col-md-6'>
                    {!! Form::text('last_name',['class' => 'form-control'])!!}
                </div>
            </div>
            <div class='form-group'>
                {!! Form::label('email','Email Address:',['class'=>'col-xs-12 col-md-3']) !!}
                <div class= 'col-xs-12 col-md-6 '>
                    {!! Form::text('email',['class' => 'form-control'])!!}
    <div class='form-group'>
            {!! Form::label('password','Password:',['class'=>'col-xs-12 col-md-3']) !!}
                <div class= 'col-xs-12 col-md-6'>
                    {!! Form::password('password',['class' => 'form-control'])!!}
                </div>
            </div>

                    <div class='form-group'>
            {!! Form::label('password_confirmation','Confirm Password:',['class'=>'col-xs-12 col-md-3']) !!}
                <div class= 'col-xs-12 col-md-6'>
                    {!! Form::password('password_confirmation',['class' => 'form-control'])!!}
                </div>
            </div>
                    </div>  <div class='btn btn-small'>
                {!! Form::submit('Join Us!',['class'=>'btn btn-success btn-sm form-control'])!!}
            </div>

        {!! Form::close() !!}
        </div>

.js文件：

$(function(){

$('#sign-up').on('submit',function(e){
    $.ajaxSetup({
        header:$('Meta[name="_token"]').attr('content')
    })
    e.preventDefault(e);

        $.ajax({

        type:"POST",url:'/register',data:$(this).serialize(),dataType: 'json',success: function(data){
            console.log(data);
        },error: function(data){

        }
    })
    });
});

控制器：

<?PHP 

namespace App\Http\Controllers;

use App\Http\Requests\CreateRegisterRequest;
use App\Http\Controllers\Controller;
use App\User;
use Illuminate\HttpResponse;
use Input;
class UserController extends Controller
{

    public function create(CreateRegisterRequest $request)
    {

    }

    public function show()
    {
        return view('user.profile');
    }

}

表格要求：

<?PHP

namespace App\Http\Requests;

use App\Http\Requests\Request;

class CreateRegisterRequest extends Request
{
    public function authorize()
    {
        return true;
    }
public function rules()
    {
        return [
            'first_name' =>'required','last_name'=>'required','url'=>'url','description','email'=>'unique:users,email|email','password'=>'min:6|confirmed','password_confirmation'=>'min:6'


        ];
    }
}
