Angular JS-检测何时所有$ http（）已完成

像这样做：

angular.module('app').factory('httpInterceptor', ['$q', '$rootScope',    function ($q, $rootScope) {        var loadingCount = 0;        return { request: function (config) {     if(++loadingCount === 1) $rootScope.$broadcast('loading:progress');     return config || $q.when(config); }, response: function (response) {     if(--loadingCount === 0) $rootScope.$broadcast('loading:finish');     return response || $q.when(response); }, responseError: function (response) {     if(--loadingCount === 0) $rootScope.$broadcast('loading:finish');     return $q.reject(response); }        };    }]).config(['$httpProvider', function ($httpProvider) {    $httpProvider.interceptors.push('httpInterceptor');}]);

然后使用绑定到

$rootScope

$rootScope.$on('loading:progress', function (){    // show loading gif});$rootScope.$on('loading:finish', function (){    // hide loading gif});
