ASP.NET MVC 2: Dynamically enabling/disabling client side validation

Question

Using MicrosoftMvcValidation.js for client side validation, is there an easy way of programatically (in javascript) turning the validation off and on for particular fields?

Is it possible for example to use jquery to bind/unbind the events?

It involves a customization to MicrosoftMvcValidation.debug.js

Change this:

if (!Sys.Mvc._validationUtil.stringIsNullOrEmpty(errorMessage)) {
    Array.add(errors, errorMessage);
}

To this:

var inptEl = $get(context.fieldContext.elements[0].id);
if (!Sys.Mvc._validationUtil.stringIsNullOrEmpty(errorMessage) && !inptEl.disabled) {
    Array.add(errors, errorMessage);
}
else
    Sys.UI.DomElement.removeCssClass(inptEl, Sys.Mvc.FieldContext._inputElementErrorCss);
