我试图在我的 CI 应用程序中实现 maykinmedia/dual-listbox，插件工作正常，但是当我提交表单时，$_POST 变量不包含任何值。我可以提供 javascript 部分，但它是插件的标准初始化，数据由 CI 控制器传递。请帮忙。在 html 部分下方，在这种情况下，选择标记中缺少名称，但即使添加它，也不会改变结果。

<select id="data" class="kt-dual-listbox" multiple
                            data-available-title="Source Options"
                            data-selected-title="Destination Options"
                            data-add="<i class='flaticon2-next'></i>"
                            data-remove="<i class='flaticon2-back'></i>"
                            data-add-all="<i class='flaticon2-fast-next'></i>"
                            data-remove-all="<i class='flaticon2-fast-back'></i>"
                    >
                    <?php foreach ($contents_data_data as $content_data_data){ ?>
                        <option value="<?= $content_data_data->id ?>"><?= $content_data_data->name ?></option>
                    <?php } ?>
</select>

$this.empty();

在javascript文件中，解决问题；但随后源选项列表将显示 2 次相同的选项。
