angularjsHow do I use an AngularJS factory?
An AngularJS factory is a service that can be used to create custom objects and functions. To use an AngularJS factory, you need to first define it in your application module. For example:
var app = angular.module('myApp', []);
app.factory('myFactory', function() {
return {
getName: function() {
return 'John Doe';
}
}
});
You can then inject the factory into your controller or service and use the functions it provides. For example:
app.controller('myController', function($scope, myFactory) {
$scope.name = myFactory.getName();
});
The output of this code would be John Doe
.
Code explanation
var app = angular.module('myApp', []);
- This line defines a new AngularJS application module.app.factory('myFactory', function() {
- This line defines a new factory with the namemyFactory
.return {
- This line returns an object containing all the functions and variables that will be available from the factory.getName: function() {
- This line defines a function calledgetName
which will be available from the factory.return 'John Doe';
- This line returns the stringJohn Doe
when thegetName
function is called.$scope.name = myFactory.getName();
- This line calls thegetName
function from themyFactory
factory and assigns the returned value to the$scope.name
variable.
