问题 What is the difference between value and ng-value attributes in angularjs templates? If I use ng-if on the field using value attribute it works properly but if I change the attribute value to ng-value it stops working. example 1 // it works <input type='radio' ng-model='difficulty' value='hard'/> <div ng-if="difficulty == 'hard'"> <p>difficulty is hard</p> </div> Example 2 // it doesn't work <input type='radio' ng-model='level' ng-value='hard'/> <div ng-if= "level == 'hard'" > <p>level is

问题 Is it possible to inject one service into another service in angularJS? 回答1: Yes. follow the regular injection rule in angularjs. app.service('service1', function(){}); //Inject service1 into service2 app.service('service2',function(service1){}); Thanks to @simon. It is better to use Array injection to avoid minifying problem. app.service('service2',['service1', function(service1) {}]); 回答2: Yes. Like this (this is a provider, but same thing applies) module.provider('SomeService', function ()

问题 I have a service in Angular which uses my API to get user information and provides it to my controllers. It's set up like this: angular.module('myApp', ['myApp.filters', 'myApp.services', 'myApp.directives', 'ngResource', 'infinite-scroll', 'ui.bootstrap', 'ngCookies', 'seo']) .service('userInfo', function($http, $cookies){ $http.get('/api/users/' + $cookies.id). success(function(data) { var userInfo = data.user[0]; return userInfo; }); }). // other stuff comes after this In my controllers, I

问题 I am very new to angularJS. I am searching for accessing services from RESTful API, but I didn't get any idea. How can I do that? 回答1: Option 1: $http service AngularJS provides the $http service that does exactly what you want: Sending AJAX requests to web services and receiving data from them, using JSON (which is perfectly for talking to REST services). To give an example (taken from the AngularJS documentation and slightly adapted): $http({ method: 'GET', url: '/foo' }). success(function

问题 When using an AngularJS service to try and pass data between two controllers, my second controller always receives undefined when trying to access data from the service. I am guessing this is because the first service does a $window.location.href and I'm thinking this is clearing out the data in the service? Is there a way for me to change the URL to a new location and keep the data persisted in the service for the second controller? When I run the code below the alert in the second

问题 I’m looking for the best practice of how to bind to a service property in AngularJS. I have worked through multiple examples to understand how to bind to properties in a service that is created using AngularJS. Below I have two examples of how to bind to properties in a service; they both work. The first example uses basic bindings and the second example used $scope.$watch to bind to the service properties Are either of these example preferred when binding to properties in a service or is

问题 How do I create some sort of utils bundle that would be accessible from all my controllers? I have this route code in my main module: 'use strict'; angular.module('lpConnect', []). config(['$routeProvider', function($routeProvider) { $routeProvider. when('/home', {template: 'views/home.html', controller: HomeCtrl}). when('/admin', {template: 'views/admin.html', controller: AdminCtrl}). when('/connect', {template: 'views/fb_connect.html', controller: MainAppCtrl}). otherwise({redirectTo: '

问题 I am learning Angular.js and I am not able to figure out whats wrong with this simple code. It seems to look fine but giving me following error. **Error**: Uncaught Error: [$injector:modulerr] http://errors.angularjs.org/1.3.14/$injector/modulerr?p0=app&p1=Error%3A%20…gleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.14%2Fangular.min.js%3A17%3A381) And before adding ng-app= "app" (I was just keeping it as ng-app ) it was giving me following errors.

问题 I am trying to create a constructor function inside an angular service, which I could then use inside of my different angular controllers. The problem is, my object generated from the constructor needs access to one of the properties on my $scope object in order to function correctly. I have the implementation working with the functionality I am after, but it involves passing the $scope object into the constructor function as a parameter. Is there a better way to accomplish this? Are there
