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。

这是添加旋转器最简单的方法，我猜:-

您可以将ng-show与这些漂亮的旋转器中的任何一个的div标签一起使用 http://tobiasahlin.com/spinkit/{{这不是我的页面}}

然后你可以用这种逻辑

/ / ajax开始 美元scope.finderloader = true; http({美元 方法:“文章”, url: "你的url "， Data:{//你的数据 ｝ })。然后(函数mysucceeded (response) { 美元scope.finderloader = false; 美元scope.search = false; 美元的范围。myData = response.data.records; })； / / ajax结束 <div ng-show="finderloader" class=spinner></div> //在HTML的正确位置添加这个

用下面的代码创建指令:

$scope.$watch($http.pendingRequests, toggleLoader);

function toggleLoader(status){
  if(status.length){
    element.addClass('active');
  } else {
    element.removeClass('active');
  }
}

.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);
  }
}

如果你在一个服务/工厂中包装你的api调用，那么你可以跟踪那里的加载计数器(每个答案和@JMaylin的优秀同步建议)，并通过一个指令引用加载计数器。或其任何组合。

API 包装器

yourModule
    .factory('yourApi', ['$http', function ($http) {
        var api = {}

        //#region ------------ spinner -------------

        // ajax loading counter
        api._loading = 0;

        /**
         * Toggle check
         */
        api.isOn = function () { return api._loading > 0; }

        /**
         * Based on a configuration setting to ignore the loading spinner, update the loading counter
         * (for multiple ajax calls at one time)
         */
        api.spinner = function(delta, config) {
            // if we haven't been told to ignore the spinner, change the loading counter
            // so we can show/hide the spinner

            if (NG.isUndefined(config.spin) || config.spin) api._loading += delta;

            // don't let runaway triggers break stuff...
            if (api._loading < 0) api._loading = 0;

            console.log('spinner:', api._loading, delta);
        }
        /**
         * Track an ajax load begin, if not specifically disallowed by request configuration
         */
        api.loadBegin = function(config) {
            api.spinner(1, config);
        }
        /**
         * Track an ajax load end, if not specifically disallowed by request configuration
         */
        api.loadEnd = function (config) {
            api.spinner(-1, config);
        }

        //#endregion ------------ spinner -------------

        var baseConfig = {
            method: 'post'
            // don't need to declare `spin` here
        }

        /**
         * $http wrapper to standardize all api calls
         * @param args stuff sent to request
         * @param config $http configuration, such as url, methods, etc
         */
        var callWrapper = function(args, config) {
            var p = angular.extend(baseConfig, config); // override defaults

            // fix for 'get' vs 'post' param attachment
            if (!angular.isUndefined(args)) p[p.method == 'get' ? 'params' : 'data'] = args;

            // trigger the spinner
            api.loadBegin(p);

            // make the call, and turn of the spinner on completion
            // note: may want to use `then`/`catch` instead since `finally` has delayed completion if down-chain returns more promises
            return $http(p)['finally'](function(response) {
                api.loadEnd(response.config);
                return response;
            });
        }

        api.DoSomething = function(args) {
            // yes spinner
            return callWrapper(args, { cache: true });
        }
        api.DoSomethingInBackground = function(args) {
            // no spinner
            return callWrapper(args, { cache: true, spin: false });
        }

        // expose
        return api;
    });

微调控制项指令

(function (NG) {
    var loaderTemplate = '<div class="ui active dimmer" data-ng-show="hasSpinner()"><div class="ui large loader"></div></div>';

    /**
     * Show/Hide spinner with ajax
     */
    function spinnerDirective($compile, api) {
        return {
            restrict: 'EA',
            link: function (scope, element) {
                // listen for api trigger
                scope.hasSpinner = api.isOn;

                // attach spinner html
                var spin = NG.element(loaderTemplate);
                $compile(spin)(scope); // bind+parse
                element.append(spin);
            }
        }
    }

    NG.module('yourModule')
        .directive('yourApiSpinner', ['$compile', 'yourApi', spinnerDirective]);
})(angular);

使用

<div ng-controller="myCtrl" your-api-spinner> ... </div>

下面是AngularJS当前使用的咒语:

angular.module('SharedServices', [])
    .config(function ($httpProvider) {
        $httpProvider.responseInterceptors.push('myHttpInterceptor');
        var spinnerFunction = function (data, headersGetter) {
            // todo start the spinner here
            //alert('start spinner');
            $('#mydiv').show();
            return data;
        };
        $httpProvider.defaults.transformRequest.push(spinnerFunction);
    })
// register the interceptor as a service, intercepts ALL angular ajax http calls
    .factory('myHttpInterceptor', function ($q, $window) {
        return function (promise) {
            return promise.then(function (response) {
                // do something on success
                // todo hide the spinner
                //alert('stop spinner');
                $('#mydiv').hide();
                return response;

            }, function (response) {
                // do something on error
                // todo hide the spinner
                //alert('stop spinner');
                $('#mydiv').hide();
                return $q.reject(response);
            });
        };
    });

//regular angular initialization continued below....
angular.module('myApp', [ 'myApp.directives', 'SharedServices']).
//.......

这里是它的其余部分(HTML / CSS)....使用

$('#mydiv').show(); 
$('#mydiv').hide(); 

来切换它。注意:以上是在post开头的angular模块中使用的

#mydiv {  
    position:absolute;
    top:0;
    left:0;
    width:100%;
    height:100%;
    z-index:1000;
    background-color:grey;
    opacity: .8;
 }

.ajax-loader {
    position: absolute;
    left: 50%;
    top: 50%;
    margin-left: -32px; /* -1 * image width / 2 */
    margin-top: -32px;  /* -1 * image height / 2 */
    display: block;     
}

<div id="mydiv">
    <img src="lib/jQuery/images/ajax-loader.gif" class="ajax-loader"/>
</div>
