angularjs - How can I handle an Angular promise in the controller using TypeScript -

i have service makes request data:

/// <reference path="../../typings/reference.ts" />  module app { 'use strict';  export class vehiclemakeservice {      static $inject = ['$http'];     constructor(private $http: ng.ihttpservice) {}      getvehicles(): ng.ipromise<any> {          return this.$http.get('https://api.edmunds.com/api/vehicle/v2/makes?state=used&year=2015&view=basic&fmt=json')         .then(function(response) {             return response.data;         });     } }  angular.module('app').service('vehiclemakeservice', vehiclemakeservice); } 

this works expected, when attempt retrieve data in controller 'promise {$$state: object}'.

here controller:

/// <reference path="../../typings/reference.ts" />  module app { 'use strict';  interface isearchcontroller {     vehicles: any;     setvehicles(): void; }  class searchcontroller implements isearchcontroller {      vehicles: any;      static $inject = ['vehiclemakeservice'];     constructor(private vehiclemakeservice: vehiclemakeservice) {         this.vehicles = {};         this.setvehicles();          }      setvehicles(): void {         this.vehicles = this.vehiclemakeservice.getvehicles();         console.log(this.vehicles);      } } angular.module('app').controller('searchcontroller', searchcontroller); } 

i tried resolving in controller:

setvehicles(): void {         this.vehiclemakeservice.getvehicles().then(function(data) {             this.vehicles = data;             console.log(this.vehicles);         });     } 

but 'typeerror: cannot set property 'vehicles' of undefined'.

i handle kind of thing in resolve function in module config can't on occasion.

you can use arrow function ts/es6 this:

setvehicles(): void {     this.vehiclemakeservice.getvehicles().then((data) => {         this.vehicles = data;         console.log(this.vehicles);     }); } 

btw. shouldn't use internal modules in ts bad ;)

you can check example skeleton application external modules angular 1.x , typescript here.
