jquery - laravel - 无法从模态获取数据ID

问题描述

我是 Laravel 和 jQuery/Ajax 的初学者。我想从模态按钮中获取“数据 ID”，但是当我在控制台中看到“未定义”问题时，我可以顺便获取“名称”值。我的问题在哪里？

我的刀片是：

@foreach($doctors as $doctor)
      <a href="javascript:void(0)" type="button" class="btn btn-primary"  data-toggle="modal" data-target="#appointmentModal" ></a> 
@endforeach

<div class="modal fade" id="appointmentModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
    <div class="modal-dialog" role="document">
        <div class="modal-content">
        <div class="modal-header">
            <h5 class="modal-title" id="exampleModalLabel">Appointment</h5>
            <button type="button" class="close" data-dismiss="modal" aria-label="Close">
            <span aria-hidden="true">&times;</span>
            </button>
        </div>

        <div class="modal-body">
            <form  id="addAppointment" novalidate>
                @csrf
                <div class="mb-3">
                    <label>Name</label>
                    <input type="text" class="form-control" id="nameR" name="name" required>
                </div>

                <button type="submit" class="btn btn-primary" data-id="{{$doctor->id}}">Save</button>
                </form>
        </div>
    </div>
    </div>
</div>

我的 jQuery/Ajax 是：

$('#addAppointment').submit(function(e){
        e.preventDefault();

        var id = $(this).attr('data-id');
        let name = $("#nameR").val();

        console.log(id);
        
        $.ajax({
            url: "{{route('add_appointmentPost')}}",
            type:"POST",
            data:{
                name:name,
                _token:'{{ csrf_token() }}',
            },
            success:function(response){
                if(response){
                    $('#addAppointment')[0].reset();
                }
            }
        });


    });
