I've looked all over the web including several stack overflow examples for a solution to the question. To be specific, I tried this:
var disableButton = function() {
  document.getElementById('<%= btnSubmit.ClientID %>').disabled = true;
}
$scope.isDisabled = false;
var someFunc = function() {
  $scope.isDisabled = true;
}<button OnClientClick="disableButton()" type="submit">Submit</button>
<button ng-disabled="isDisabled" type="submit">Submit</button>Neither worked as advertised. Any other suggestions? Please Angular suggestions only. Thank you.
