试图用ajax插入多选输入

Question

我正在尝试在 Laravel 中使用 ajax 存储多选输入，但出现此错误

{message: "Function name must be a string", exception: "Error", …}

这是我的刀片代码

<select class="" multiple="" id="medicine_pills" name="medicine_pills[]">
    <option value="2">test</option>
    <option value="2">test</option>
</select>

var medicine_pills = $('#medicine_pills').val();
$.ajax({
    url: '{{ url('medicine') }}',
    type: "post",
    data: {
        '_token': "{{ csrf_token() }}",
        'medicine_pills': medicine_pills,
        'last_appointment_id': last_appointment_id,
    },

在控制器中

$medicines = request()->post('medicine_pills');

foreach ($medicines as $iteam) {
    echo $medicines;
    $user = Medicine::create([
        'medicines_cats' => $iteam,
        'appointmen_id' => $last_appointment_id,
    ]);

Answer 1

<select class="" multiple="" id="medicine_pills" name="medicine_pills[]">
    <option value="2">test</option>
    <option value="2">test</option>
</select>

var medicine_pills = $("input[name='medicine_pills[]']").val();
$.ajax({
    url: '{{ url('medicine') }}',
    type: "post",
    data: {
        '_token': "{{ csrf_token() }}",
        'medicine_pills': medicine_pills,
        'last_appointment_id': last_appointment_id,
    },

请尝试一下。
