这是我的控制器文件：

namespace App\Http\Controllers;

use Validator;
use Illuminate\Http\Request;
use App\companies;

class AjaxController extends Controller
{
public function index()
{

    $companies = companies::all();
    return view('ajax.index',compact('companies'));
}
public function delete(Request $request)
{
    $multi_id = $request->input('multi_id');
    companies::whereIn('id',$multi_id)
    ->delete();
    return redirect('/companies')->with('success','deleted');

}
 public function store(Request $request)
{
    companies::create($request->all());
    return back();
}
public function postdata(Request $request)
{
    // $validation = Validator::make($request->all(),[
    //         'company_name' => 'required',
    //         'status' => 'required',
    //     ]);
    $validation = $request->validate([
            'company_name' => 'required',
            'status' => 'required',
        ]);
    $error_array = array();
    $success_output = '';
    if($validation->fails())
    {

        foreach ($validation->messages()->getMessages() as 
            $field_name => $messages) 
        {
            $error_array[] = $messages;
        }
    }
    else
    {
        if ($request->get('button_action') == "insert") 
        {
            $companies = new companies([

                        'company_name'  => $request->get('company_name'),
                        'status' => $request->get('status'),
                ]);
            $companies->save();
                $success_output = '<div class="alert alert-success">Data Inserted</div>';

        }

    }
        $output = array(
                'errror' => $error_array,
                'success' => $success_output
            );
            echo json_encode($output);
}

}

但是当我单击弹出窗口上的“保存”按钮时，它不起作用，并且控制台中没有显示任何错误。在这种情况下有人可以帮助我吗？我想在数据库表和数据表中添加新的公司名称。我的路线链接是： Route::post('companies/postdata',AjaxController@postdata)->name('companies/postdata');

我看到两件事，你在哪里

$.ajaxSetup({ headers: { 'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content') } });

？

我看到公司有错字

Ajax：

url：“ {{route（'companies / postdata'）}}”，

路线：

->名称（“ comapnies / postdata”）；

Ajax发布功能在laravel文档中不起作用
