我有一个表格，用客户信息呈现。有一个下拉菜单，在更改时会使用 JavaScript 在 HTML 中插入新的表单元素。在此事件之后，我得到了用于验证的 JavaScript。

当我发布表单时，我确实将新元素数组放入我的模型中。如果现在我进行服务器验证并且出现错误，我会将所有内容返回到视图，这次使用 razor 生成新元素。到目前为止一切都很好。但是客户端验证不起作用！我确实验证了表单中的其他元素，但没有验证从集合中生成的元素，这些元素之前是手动添加的。

我确实看到元素数组没有 data-val 属性。

如果视图全部呈现，包括值数组的循环，为什么我没有在表单的这一部分获得客户端验证？

          for (int i = 0; i < Model.pasajeros.Count(); i++)

            </tr>
        </table>
        <hr />
      }
  }

}

这是我观点的一部分

您需要在parse将新元素添加到 DOM 后调用该方法，以便使用不显眼的验证来注册它们：

$.validator.unobtrusive.parse('#id_of_the_form_containing_newly_added_inputs');

显然，这些元素必须具有相应的 HTML5data-*属性，这些属性指示您要对其应用的验证规则，就像在服务器上添加的输入一样。
