使用AngularJS addClass / removeClass的动画序列

var myApp = angular.module('myApp',['ngAnimate']);

myApp.controller('Controller',function($scopE) {});

myApp.directive('animated',['$animate','$window',function($animate,$window) {
  return function(scope,element,attrs) {
      scope.animate = function() {
          $animate.addClass(element,'fadeInDown').then(function() {
              $animate.removeClass(element,'fadeInDown'); // why is it not working?

              setTimeout(function() {
                  scope.$apply(function() {
                      $animate.addClass(element,'fadeOutDown');
                  });
              },0);

          });
      };
  };
}]);

我建议尝试使用纯css解决方案来保持代码更清晰.你可以看看here
