I am trying to use below date (mm/dd/yyyy) validation pattern using ng-pattern in view.

 ng-pattern=/^(d{4})-(d{2})-(d{2})$/

As soon as I start typing the date the validation error appears and stays even after having valid date such as 10/15/1988

I tried passing it through controller using var (as shown below) but behaves the same:

In Controller:

  $scope.myPattern = /^(d{4})-(d{2})-(d{2})$/;

In View:

  ng-pattern={{myPattern}}

Note: This both approach not working only in IE9
