Is there a convenient method in Angular to utilize the $filter service for retrieving an array containing only a specific property from an array of objects?
var contacts = [
{
name: 'John',
id: 42
},
{
name: 'Mary',
id: 43
},
];
var ids = $filter('filter')(contacts, /* my magical parameter */);
console.log(ids); //output [42, 43]
Any assistance or direction towards a related resource would be greatly appreciated. Thank you.
Forget about using the $filter service in angularjs, opt for the .map() method instead (Vanilla JS, ES5):
var users = [
{
username: 'Alice',
userId: 101
},
{
username: 'Bob',
userId: 102
},
];
var userIDs = users.map(function(user) {
return user.userId;
});
console.log(userIDs); //result [101, 102]
