Javascript 我无法在laravel中插入数据，然后使用ajax检索数据

我想提交from，然后使用提交的数据更新表，而不刷新页面。 这是包含表单的模态

<div class="modal fade" id="clientModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
    <div class="modal-dialog" role="document">

                    <span aria-hidden="true">&times;</span>

            <div class="modal-body">

        </div>
    </div>
</div>

这是我的控制器功能：

public function addClient(Request $request)
{
    $clients = new Client();

    $clients->client = $request->input('client');
    $clients->person = $request->input('person');
    $clients->address = $request->input('address');
    $clients->phone = $request->input('phone');
    $clients->country = $request->input('country');
    $clients->province = $request->input('province');
    $clients->city = $request->input('city');
    $clients->usd = $request->input('usd');
    $clients->cd = $request->input('cd');

    $clients->save();
    return response()->json($clients);
}

当我点击提交按钮时，什么也没发生。如果我在这里遗漏了什么或做错了什么，有人能帮我吗？提前感谢。

当您说什么都没发生时，您是否检查了浏览器开发人员工具控制台以查看是否有错误？或者，即使请求是sentError:POST 500（内部服务器错误），那么错误就出现在服务器代码上（请求正在发出，所以发生了一些事情）-您是否可以查看服务器日志，或者服务器是否碰巧将错误的描述发送回客户端？（

error:function（err）

callback在请求中可能有帮助）顺便说一句，在您的标记中似乎没有这些

$（“input[name=\u token]”

我已经插入了name token提交函数“let _token=$（“input[name=\u token]”）val（）；”然后我在数据中有：{\u token

Route::post('/add-client','ClientController@addClient')->name('client.add');

public function addClient(Request $request)
{
    $clients = new Client();

    $clients->client = $request->input('client');
    $clients->person = $request->input('person');
    $clients->address = $request->input('address');
    $clients->phone = $request->input('phone');
    $clients->country = $request->input('country');
    $clients->province = $request->input('province');
    $clients->city = $request->input('city');
    $clients->usd = $request->input('usd');
    $clients->cd = $request->input('cd');

    $clients->save();
    return response()->json($clients);
}
