dynamically remove an element's required attribute in ASP MVC?

阅读更多关于 dynamically remove an element's required attribute in ASP MVC?

问题 Is there a way, in an ASP MVC project using unobtrusive validation, to dynamically remove the Required attribute from an element? The element is decorated with a Required annotation in the view model. I thought I could remove this by removing the html attribute, "data-val-required," with JQuery but client validation still treats the element as required. Is it impossible to manipulate the element's validation by manipulating the unobtrusive validation attributes? This is what I tried, but it

Event hooks for MVC unobtrusive remote validation

阅读更多关于 Event hooks for MVC unobtrusive remote validation

问题 Is there a way to hook into MVC3 unobtrusive remote validation on the client, before data is submitted to the remote method, and after a result is returned from the remote method? I am trying to tell a remote validator to only perform validation if the submit button is clicked.

I need to make sure that method is

Using unobtrusive validation in ASP.NET MVC 3, how can I take action when a form is invalid?

阅读更多关于 Using unobtrusive validation in ASP.NET MVC 3, how can I take action when a form is invalid?

问题 I have a page with jQuery UI tabs on it, and a single required field on the first tab. Validation works, and the validation message appears next to the field if the user hasn't entered a value. However, if the user is not on the first tab, it isn't obvious that the field is invalid. In this case, I would like to show the first tab, but I'm not sure how to go about registering a callback for an 'invalid' event, if there is one. I have also considered showing a validation summary above the tabs

I followed this excellent post for generating dynamic controls in my mvc3 app. And now I am trying to do client side unobstructive validation for phonenumber field. So I added 'Required' attribute on the 'PhoneNumber' property. The unobstructive validation works for the phonenumber fields which are generated/rendered by the server (i.e. on pageload).
