ASP.NET MVC 中的选择性客户端验证
如何使用 MVC 2 内置验证系统实现选择性客户端验证
？
假设我的表单标题中有一个复选框“您有孩子吗？”
，如果选中，则下面的文本框应为必填
（标题为“孩子数量”的文本框）。
How can I implement selective client side validation
using MVC 2 built-in validation system?
Assume I have a checkbox in my form title "Do you have any child?"
and if checked the textbox below it should be required
(textbox titled Number of children).

一些可能会让您思考的选项。在多个发布操作的情况下（例如，单击表单上的取消按钮不应触发验证），我已确保表单仅发布一个操作，而其他任何内容本质上都是样式链接。在这种情况下，验证不会触发。
如果像您的情况一样，您有复杂的验证，我建议创建一个自定义验证器并注册一个客户端适配器，例如，
因此您将编写一个自定义验证属性、一个自定义模型验证器和一些 JavaScript 代码来注册一个新客户端侧面验证器。这种方法过去对我有用，但对另一个模型属性的依赖可能有点问题。
希望这有帮助。
A few options that might get you thinking here. In the case of multiple post actions (e.g. clicking cancel button on a form shouldn't fire validation) I have made sure that forms only post one actions and anything else is essentially a styled link. Validation won't fire in this case.
If, as is in your case, you have complex validation I would suggest creating a custom validator and registering a client side adapter e.g.
So you'd be writing a custom validation attribute, a custom model validator and some JavaScript code to register a new client side validator. This sort of approach has worked for me in the past but the dependency on another model property can be a bit of a problem.
Hopefully this helps.
