angular-promise

问题 I created a short example of an Angular 2 application built with NativeScript , what I expect is the variable foo to be "foo" at the beginning, then the ngOnInit() first change it to "bar" and then the promise return and I should see "foobar" in the Label, but instead I see "bar". The execution is as expected as I can see in the logs: JS: afterBar JS: promise new JS: promise than component.ts foo:String="foo"; ngOnInit() { this.foo = "bar"; console.log("afterBar"); var promise = new Promise(

问题 My $q.all() is working fine. The below code is in my primary service and when done everything is returned to the controller correctly. However I am trying to pre-sort the final array returned to the controller its not working. The sort function itself works - its the identical function in my controller that I use to manually sort the results on my template page. Its just the initial results don't come back sorted. I know its an async issue, but can't figure out where the sort needs to go

问题 I have a lack of understanding asynchronous operation while I'm dealing with a promise function in angular. So basically, I'm trying to get a value from a promise method and assign it to a global variable in a component. However, I am unable to retrieve the value when I click on a button once and it finally starts to show the value after I clicked on a button once more. Error I get when I clicked it once : Cannot read property 'matchId' of undefined Value I get after I clicked it twice : 3

问题 I have written a bit of code that allows a user to upvote / downvote recipes in a manner similar to Reddit. Each individual vote is stored in a Firestore collection named votes , with a structure like this: {username,recipeId,value} (where value is either -1 or 1) The recipes are stored in the recipes collection, with a structure somewhat like this: {title,username,ingredients,instructions,score} Each time a user votes on a recipe, I need to record their vote in the votes collection, and

问题 What I am trying to achieve is using a filter that will return success or error from the ret() function. With the code below it returns {} , which is probably its promise. .filter('postcode', ['$cordovaSQLite', '$q', function($cordovaSQLite, $q) { return function(PostCodeID) { function ret() { var def = $q.defer(); ionic.Platform.ready(function() { if (window.cordova) { var db = $cordovaSQLite.openDB({ name: "msddocapp.db" }); } else { var db = window.openDatabase("msddocapp.db", "1", "ES

问题 I've been learning/working on a newbie project which is basicly a simple task manager(similiar to those todo list projects). And I designed a user login page for this project and here is how it works. So I have two functions siteLogin() for logging in and inside it I want to use second function showTasks() after user logs in which returns the usertasks it gets from API ( promises I know ).

问题 Basically what I want to do, is to assign some model value from function call that resolves promise. Like so value = someFun() This is a service from which I call this function app.factory('SomeService', function($q) { return { someFun: function() { var d = $q.defer(); try { d.resolve("hi"); } catch (e) { d.reject(e); } return d.promise.then(function(text){ return text; }); } }; }); Here is the HTML code <div ng-init="value = 'yes'"> <pre>{{value |json}}</pre> </div> <button type="button" ng
