ASP.net MVC 3 jQuery Validation; Disable Unobtrusive OnKeyUp?

Question

Is there a way to disable the jQuery Validation for a certain validator (creditcard) so that it only occurs onblur, instead of onkeyup? Based on the jQuery Validator documentation I thought I could do something like this: ``` $(function () { $("[data-val-creditcard]").validate({ onkeyup: false }) }); ``` However, it doesn't seem to be working. I also tried doing the following on my validator: ``` public class CreditCardValidator : DataAnnotationsModelValidator { string _message; public CreditCardValidator(ModelMetadata metadata, ControllerContext context, CreditCardAttribute attribute) : base(metadata, context, attribute) { _message = attribute.ErrorMessage; } public override IEnumerable GetClientValidationRules() { var rule = new ModelClientValidationRule { ErrorMessage = _message, ValidationType = "creditcard" }; rule.ValidationParameters.Add("onkeyup", false); return new[] { rule }; } } ``` It doesn't work either, but I was just takin…

Ok guys,

I was in the same problem and found this thread: http://old.nabble.com/-validate--onkeyup-for-single-field-td21729097s27240.html

The idea is basically to overwrite the keyup event and return false. So in your specific case you'll need to add:

```
$('#my-form').validate({
   rules: {
     [...]
   }
} 
// Disable keyup validation for credit card field
$("[data-val-creditcard]").keyup(function() { return false } );
```

And you'll see that your credit card field is only checked on blur or submit (but the rest is working on keyup also).

I was looking for the same solution, and found that the answer here could be improved, so I thought it would be nice to share it here.
