Angular $q returning promise multiple $http calls

由 ☆樱花仙子☆ 提交于 2019-12-19 03:13:12
问题 I'm working on an $http call that loops over each of multiple api's and returns all of the data in one object. I usually have the promise ready to resolve when the $http call has been made. Similar to this: function getAllData(api) { return $http({ method: 'GET', url: '/api/' + api }) .then(sendResponseData) .catch (sendGetVolunteerError); } The current function I have loops over each api and pushes each object in the api into an array and then pushes it into an overall array. I had this

问题 I changed the scope variable in an if statement and outside the if statement it turned into an undefined variable app.controller("Login", function($scope, $window,$http){ var status; $scope.loginUser = function(logData){ $http.post('/corporate/login',logData).then(function(response){ var data = response.data var status = data.success; if(status == true){ $scope.logStatus = true; console.log($scope.logStatus); // prints true }else{ $scope.logStatus = false; } }) console.log($scope.logStatus);

Do I really need to return a promise in test when using Chai as Promised?

由 冷暖自知 提交于 2019-12-18 07:06:56
问题 Chai as Promised documentation states as follows: Notice : either return or notify(done) must be used with promise assertions. And the examples on the site are as follows: return doSomethingAsync().should.eventually.equal("foo"); doSomethingAsync().should.eventually.equal("foo").notify(done); The thing is; I actually wrote a test using chai as promised without returning the promise. Like so: it('should resolve user', function () { $state.get(state).resolve.user(dataservice, { userId: testUser

$q promise with Underscore _each

由 ╄→гoц情女王★ 提交于 2019-12-17 16:58:41
问题 So I have a method in a angularjs server that is calling a method that returns a promise for each method in a array. I am using underscore _each to loop through the array. I want to wait until the entire array is processed before I call the final line of code in the method.. So... function ProcessCoolStuff(coolStuffs) { var stuff = []; _.each(coolStuffs, function(coolStuff) { //Some method using $q to return makeStuffCooler(coolStuff).then(function(coolerStuff) { stuff.push(coolerStuff); });

Angular 1.6.0: “Possibly unhandled rejection” error [duplicate]

问题 This question already has answers here : Possibly unhandled rejection in Angular 1.6 (9 answers) Closed last year . We have a pattern for resolving promises in our Angular app that has served us well up until Angular 1.6.0: resource.get().$promise .then(function (response) { // do something with the response }, function (error) { // pass the error the the error service return errorService.handleError(error); }); And here is how we are triggering the error in Karma: resourceMock.get = function

How to access the value of a promise?

由 痞子三分冷 提交于 2019-12-16 23:55:33
问题 I'm looking at this example from Angular's docs for $q but I think this probably applies to promises in general. The example below is copied verbatim from their docs with their comment included: promiseB = promiseA.then(function(result) { return result + 1; }); // promiseB will be resolved immediately after promiseA is resolved and its value // will be the result of promiseA incremented by 1 I'm not clear how this works. If I can call .then() on the result of the first .then() , chaining them
