Angularjs ng显示未显示变量检查

这是我的控制器：

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

还有我想展示的导航：

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

---

将其设置为

$scope

var:

$scope.cookieSet = $cookies.user_id;

---

常规

var

变量在视图中不可访问。

啊，我不知道，也谢谢你的解释！

$scope.cookieSet = $cookies.user_id;
