检查选择了哪个选项

Question

单击按钮时，我正在使用AJAX来显示一个PHP模态，其中包含一个表单。这是一种编辑表单，因此字段中会填充从AJAX接收的数据，这些数据是通过处理程序调用PHP函数的。但是，我需要一种select输入的方法来知道选择了哪个，但是要用于该数据的是JavaScript。通常我会使用诸如

$occasionTypes = getPublishedOccasionTypes($connection);
if($occasionTypes != NULL){
    foreach ($occasionTypes as $occasionType) {
        $selected = (isset($booking['reservation_type']) && ($booking['reservation_type'] == $occasionType['id'])) ? 'selected' : NULL;
        $occasionSelect .= '<option value='.$occasionType['id'].' '.$selected.'>'.$occasionType['name'].'</option>';
    }
}

但是在这种情况下，$booking['reservation_type]是没有用的，因为我需要的实际值在输入（我创建的隐藏值）中，但是由JavaScript填充。有任何想法吗？这也是我的JavaScript

$.ajax({
    type: 'POST',
    url: "/modules/ajax/ajax_handler.php",
    data: data
})
.done((result)=>{
    result = JSON.parse(result);
    console.log(result);
    
    $('#firstName').val(result.customer_first_name);
    $('#lastName').val(result.customer_last_name);
    $('#email').val(result.customer_email);
    $('#number').val(result.customer_mobile);
    $('#date').val(result.reservation_date);
    $('#time').val(result.reservation_time);
    $('#size').val(result.party_size);
    $('#occasion').val(result.occasion_type);
    $('#comment').val(result.special_requirements);
    $('#code').val(pcode);
    $('#customerCode').val(result.customer_code);
    
    $('#editModal').modal('show');
    
})

MODAL
