ng-show不显示带有变量检查

Question

This is my controller:

capApp.controller('cookieCtrl', ['$scope','$cookies', function($scope, $cookies) {
  var cookieSet = $cookies.user_id;
  alert('coolkie is ' + cookieSet); // this is fine and shows the value
}]);

And the nav I want to show:

<div id="siteNav2" ng-controller="cookieCtrl">
  <nav class="navbar navbar-inverse navbar-fixed-top" ng-show="cookieSet">
    ... all nav here ...
  </nav>
</div>

But it shows, then disappears...

I also tried, but same result:

ng-show="cookieSet != null"

Answer 1

Set it to a $scope var:

$scope.cookieSet = $cookies.user_id;

Regular var variables are not accessible in the view.
