angularJS loading 载入画面

在请求网络的时候,显示loading画面

1. 使用http的interceptor,截断处理所有的http请求和响应,以及错误。在request的时候设置$rootScope.loading=True,在反馈的时候设置$rootScope.loading=False.

2. 设置遮罩div,ng-show=loading,即请求中显示遮罩,请求完毕不显示

细节:

interceptor

      $httpProvider.interceptors.push([‘$q‘,‘$rootScope‘,function($q,$rootScope){
            return {
                ‘request‘: function(config){
                    $rootScope.loading = true;
                    return $q.resolve(config);
                },
                ‘response‘: function(response){
                    $rootScope.loading = false;
                    return $q.resolve(response);
                },
                ‘requestError‘:function(rejection){
                    $rootScope.loading = false;
                    return $q.reject(rejection);
                },
                ‘responseError‘:function(rejection){
                    $rootScope.loading = false;
                    return $q.reject(rejection);
                }
            }
        }]);

    <div class="mask"></div>
    <div class="alert alert-info">
