对隐藏字段进行验证 [英] Perform validation on hidden fields

问题描述

我有以下看法：

    @Html.LabelFor(m => m.CompanyPostCode)
    @Html.TextBoxFor(m => m.CompanyPostCode)

    @Html.LabelFor(m => m.CompanyCity)
    @Html.TextBoxFor(m => m.CompanyCity)

    @Html.HiddenFor(m => m.CompanyCityID)

所有属性都被标记为 [必需的]在我看来，模型。然后，问题是，我CompanyCityID（标记为必填）是隐藏的，因此没有被验证在视图中进行。如果我在我看来，这显示属性中的验证完成。

All attributes are marked as [Required] in my view model. Then problem is that my CompanyCityID (marked as Required) is hidden and thus no validation is done in the view. If I show this attribute in my view the validation is done.

我的问题：是否有可能在一个隐藏字段进行验证？一种解决方法存在吗？

My question: is it possible to perform a validation on a hidden field? A workaround exist?

这可能看起来有点怪来验证隐藏字段。其原因是，该字段从jQuery的基于特殊规则填充。如果不填，我知道的东西是不是在视图中有效。

It may seems a little strange to validate a hidden field. The reason is that this field is filled from jQuery based on special rules. If it is not filled, I know something is not valid on the view.

感谢。

推荐答案

可能的原因可能是有忽略：：隐藏在行 jquery.validate.unobtrusive.js 文件。

The possible reason can be that there is ignore: ':hidden' line in jquery.validate.unobtrusive.js file.

1.9.0版本后，它是默认的行为。您可以手动固定通过添加

After 1.9.0 version it is a default behaviour. You can fix that manually by adding

$.validator.setDefaults({ ignore: [] });

正如你所看到的这里

另一个变化应该与隐藏要素的形式设置
  更容易，这些都是现在默认（忽略的选择忽略了
  ：隐藏现在默认的）。在理论上，这可能会破坏现有的
  建立。在不可能的情况下，它实际上呢，您可以修复它
  设置忽略选项为[]（方括号无
  引号）。

Another change should make the setup of forms with hidden elements easier, these are now ignored by default (option "ignore" has ":hidden" now as default). In theory, this could break an existing setup. In the unlikely case that it actually does, you can fix it by setting the ignore-option to "[]" (square brackets without the quotes).
