下面的方法将记录所有的请求，并且只在所有请求完成时隐藏:

app.factory('httpRequestInterceptor', function(LoadingService, requestCount) { return { request: function(config) { if (!config.headers.disableLoading) { requestCount.increase(); LoadingService.show(); } return config; } }; }).factory('httpResponseInterceptor', function(LoadingService, $timeout, error, $q, requestCount) { function waitAndHide() { $timeout(function() { if (requestCount.get() === 0){ LoadingService.hide(); } else{ waitAndHide(); } }, 300); } return { response: function(config) { requestCount.descrease(); if (requestCount.get() === 0) { waitAndHide(); } return config; }, responseError: function(config) { requestCount.descrease(); if (requestCount.get() === 0) { waitAndHide(); } var deferred = $q.defer(); error.show(config.data, function() { deferred.reject(config); }); return deferred.promise; } }; }).factory('requestCount', function() { var count = 0; return { increase: function() { count++; }, descrease: function() { if (count === 0) return; count--; }, get: function() { return count; } }; })

这是我的解决方案，我觉得比其他贴在这里的要容易得多。虽然不知道它有多“漂亮”，但它解决了我所有的问题

我有一个css样式叫做loading

.loading { display: none; }

加载div的html可以是任何东西，但我使用了一些FontAwesome图标和旋转方法:

<div style="text-align:center" ng-class="{ 'loading': !loading }">
    <br />
    <h1><i class="fa fa-refresh fa-spin"></i> Loading data</h1>
</div>

在你想要隐藏的元素上，你只需这样写:

<something ng-class="{ 'loading': loading }" class="loading"></something>

在函数中，我把这个设为load。

(function (angular) {
    function MainController($scope) {
        $scope.loading = true

我使用的是SignalR，所以在hubProxy.client.allLocks函数(当它完成了通过锁)，我只是把

 $scope.loading = false
 $scope.$apply();

当页面加载时，这也隐藏了{{someField}}，因为我在load上设置了加载类，AngularJS随后删除了它。

.factory('authHttpResponseInterceptor', ['$q', function ($q) {
        return {
            request: function(config) {
                angular.element('#spinner').show();
                return config;
            },
            response : function(response) {
                angular.element('#spinner').fadeOut(3000);
                return response || $q.when(response);
            },
            responseError: function(reason) {
                angular.element('#spinner').fadeOut(3000);
                return $q.reject(reason);
            }
        };
    }]);



 .config(['$routeProvider', '$locationProvider', '$translateProvider', '$httpProvider',
            function ($routeProvider, $locationProvider, $translateProvider, $httpProvider) {
                $httpProvider.interceptors.push('authHttpResponseInterceptor');
    }
]);

in your Template
<div id="spinner"></div>


css   

#spinner,
#spinner:after {
  border-radius: 50%;
  width: 10em;
  height: 10em;
  background-color: #A9A9A9;
  z-index: 10000;
  position: absolute;
  left: 50%;
  bottom: 100px;
}
@-webkit-keyframes load8 {
  0% {
    -webkit-transform: rotate(0deg);
    transform: rotate(0deg);
  }
  100% {
    -webkit-transform: rotate(360deg);
    transform: rotate(360deg);
  }
}
@keyframes load8 {
  0% {
    -webkit-transform: rotate(0deg);
    transform: rotate(0deg);
  }
  100% {
    -webkit-transform: rotate(360deg);
    transform: rotate(360deg);
  }
}

如果你正在使用ngResource，对象的$resolved属性对加载器很有用:

对于资源，如下所示:

var User = $resource('/user/:id', {id:'@id'});
var user = User.get({id: 1})

你可以将加载器链接到资源对象的$resolved属性:

<div ng-hide="user.$resolved">Loading ...</div>

下面的方法将记录所有的请求，并且只在所有请求完成时隐藏:

app.factory('httpRequestInterceptor', function(LoadingService, requestCount) { return { request: function(config) { if (!config.headers.disableLoading) { requestCount.increase(); LoadingService.show(); } return config; } }; }).factory('httpResponseInterceptor', function(LoadingService, $timeout, error, $q, requestCount) { function waitAndHide() { $timeout(function() { if (requestCount.get() === 0){ LoadingService.hide(); } else{ waitAndHide(); } }, 300); } return { response: function(config) { requestCount.descrease(); if (requestCount.get() === 0) { waitAndHide(); } return config; }, responseError: function(config) { requestCount.descrease(); if (requestCount.get() === 0) { waitAndHide(); } var deferred = $q.defer(); error.show(config.data, function() { deferred.reject(config); }); return deferred.promise; } }; }).factory('requestCount', function() { var count = 0; return { increase: function() { count++; }, descrease: function() { if (count === 0) return; count--; }, get: function() { return count; } }; })

分享来自@bulltorious的精彩答案的我的版本，更新到更新的angular构建(我使用了1.5.8版本的代码)，还加入了@JMaylin的想法，使用计数器来健壮地处理多个并发请求，以及选择跳过显示小于最小毫秒数的请求动画:

var app = angular.module('myApp');
var BUSY_DELAY = 1000; // Will not show loading graphic until 1000ms have passed and we are still waiting for responses.

app.config(function ($httpProvider) {
  $httpProvider.interceptors.push('busyHttpInterceptor');
})
  .factory('busyHttpInterceptor', ['$q', '$timeout', function ($q, $timeout) {
    var counter = 0;
    return {
      request: function (config) {
        counter += 1;
        $timeout(
          function () {
            if (counter !== 0) {
              angular.element('#busy-overlay').show();
            }
          },
          BUSY_DELAY);
        return config;
      },
      response: function (response) {
        counter -= 1;
        if (counter === 0) {
          angular.element('#busy-overlay').hide();
        }
        return response;
      },
      requestError: function (rejection) {
        counter -= 1;
        if (counter === 0) {
          angular.element('#busy-overlay').hide();
        }
        return rejection;
      },
      responseError: function (rejection) {
        counter -= 1;
        if (counter === 0) {
          angular.element('#busy-overlay').hide();
        }
        return rejection;
      }
    }
  }]);
