javascript - 通过检查模型中的 bool 值来显示元素

Question

我想根据名为 status 的模型中的 bool 值显示接受、拒绝等引导徽章。这里的问题是我尝试使用 jquery 执行此操作，但它要么全部显示，要么全部隐藏。所以我猜它无法读取状态值。我打开开发者工具，没有报错。我需要指导。感谢您的帮助。

 @for (int i = 0; i < Model._Requests.Count(); i++)
                            {


                                <tr>

                                    <td>
                                        @Html.DisplayFor(x => Model._Requests[i].Account_Name)
                                    </td>
                                    <td>
                                        @Html.DisplayFor(x => Model._Requests[i].LOB)
                                    </td>
                                    <td>
                                        @Html.DisplayFor(x => Model._Requests[i].Operation_Date)
                                    </td>

                            }
                                </tbody>

                                </table>

脚本

 var flag = $('[name = "Status"]').val();
        if (flag === false) {
            $('#pend').show();
        }
        else {
            $('#pend').hide();
        }

我想要展示的徽章

<span name="badge" class="badge badge-warning" id="pend">WTF</span>

如果状态之后没有改变，只需在你的cshtml中动态地设置一些类给这个项目

<span name="badge" class="badge badge-warning @{Model.Status ? "visible" : "invisible"}" id="pend">WTF</span>

如果它确实发生变化，您必须触发该值变化的事件
