Angular - abort ajax request when using Restangular

You can abort $http calls via the timeout config property, which can be a Promise, that aborts the request when resolved.

So in restangular, you can do this like

var abort = $q.defer();Restangular.one('foos', 12345).withHttpConfig({timeout: abort.promise}).get();abort.resolve();

To integrate it with your usecase, for example, you could have this in your service:

var abortGet;this.getRecords = function(params) {  ...  if (abortGet) abortGet.resolve();  abortGet = $q.defer();  return Restangular    .all('/api/records')    .withHttpConfig({timeout: abortGet.promise})    .post(filters);}

This way calling getRecords always aborts the previous call if has not been resolved yet!

Hope this helps!

This is another approach if you want to abort all http requests when change the state for UI-router:

angular    .run(function(HttpHandlerSrv) {        HttpHandlerSrv.abortAllRequestsOn('$stateChangeSuccess');        HttpHandlerSrv.R.setFullRequestInterceptor(function(element, operation, route, url, headers, params, httpConfig) {            httpConfig = httpConfig || {};            if(httpConfig.timeout === undefined) {                httpConfig.timeout = HttpHandlerSrv.newTimeout();            }            return { element: element, params: params, headers: headers, httpConfig: httpConfig };        });    })    .factory('HttpHandlerSrv', HttpHandlerSrv);    /** ngInject */    function HttpHandlerSrv($q, $rootScope, Restangular) {        var requests = [];        return {            R: Restangular,            newTimeout: newTimeout,            abortAllRequests: abortAllRequests,            abortAllRequestsOn: abortAllRequestsOn        };        function newTimeout() {            var request = $q.defer();            requests.push(request);            return request.promise;        }        function abortAllRequests() {            angular.forEach(requests, function(request) {                request.resolve();            });            requests = [];        }        function abortAllRequestsOn(event) {            $rootScope.$on(event, function(event, newUrl, oldUrl) {                if(newUrl !== oldUrl) { abortAllRequests(); }            });        }    }
