这对我来说很管用:

HTML:

  <div id="loader" class="ng-hide" ng-show="req.$$state.pending">
    <img class="ajax-loader" 
         width="200" 
         height="200" 
         src="/images/spinner.gif" />
  </div>

角:

  $scope.req = $http.get("/admin/view/"+id).success(function(data) {          
      $scope.data = data;
  });

当$http返回的承诺是未决的，ng-show将评估它是“真实的”。一旦承诺被解决，这将自动更新…这正是我们想要的。

你也可以尝试这样做:

创建指令:

myApp.directive('loader', function () {
    return {
        restrict: 'A',
        scope: {cond: '=loader'},
        template: '<span ng-if="isLoading()" class="soft"><span class="fa fa-refresh fa-spin"></span></span>',
        link: function (scope) {
            scope.isLoading = function() {
                var ret = scope.cond === true || (
                        scope.cond &&
                        scope.cond.$$state &&
                        angular.isDefined(scope.cond.$$state.status) &&
                        scope.cond.$$state.status === 0
                    );
                return ret;
            }
        }
    };
}); 

然后向mainCtrl添加如下内容

    // Return TRUE if some request is LOADING, else return FALSE
    $scope.isLoading = function() {
        return $http.pendingRequests.length > 0;
    };

HTML可以是这样的:

<div class="buttons loader">
    <span class="icon" loader="isLoading()"></span>
</div>

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

刚刚发现了angular-busy指令，它显示了一个依赖于某些异步调用的小加载器。

例如，如果你必须创建一个GET，在$作用域中引用承诺，

$scope.req = $http.get('http://google.fr');

像这样称呼它:

<div cg-busy="req"></div>

这是GitHub。

你也可以使用bower安装它(别忘了更新你的项目依赖项):

bower install angular-busy --save

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>

https://github.com/wongatech/angular-http-loader是一个很好的项目。

例如http://wongatech.github.io/angular-http-loader/

下面的代码显示了发生请求时的模板示例/loader.tpl.html。

<div ng-http-loader template="example/loader.tpl.html"></div>
