javascript - 使用 $timeout() 在特定时间间隔后隐藏页脚和页脚消息

Question

我正在尝试使用英特尔XDK创建一个 Angular 应用程序。当我运行索引页面时，我们可以看到页脚消息。我需要的是页脚和页脚消息将使用 timeout() 5 秒后隐藏。

但是我的下面的代码不起作用。

index.html

 <div class="bar bar-footer bar-balanced" style="background-color:#444444;">
            <div class="title">{{footer_message}}</div>
        </div>

app.js

     app.controller('main', function ($scope,$interval,$timeout,$ionicModal,localStorageService,$http,$q,$templateCache) {
        $scope.footer_message ='Powered By';

        $scope.checkConnection=function() {
                    var networkState = navigator.connection.type;

                    if(networkState == Connection.NONE){
                        $scope.footer_message = "No Network Connection";

                        return false;

                    }
                    else{
                        $scope.footer_message = "Powered by";
                        return true;
                    }
                }


        $scope.showFooter=function(){
                $timeout(function () {
                    $scope.footer_message = null;
            }, 5000);
           }
        $scope.showFooter();
}
