Function
reopenClass public
Module: | @ember/object |
---|
Defined in packages/ember-runtime/lib/system/core_object.js:753
Augments a constructor's own properties and functions:
const MyObject = Ember.Object.extend({ name: 'an object' }); MyObject.reopenClass({ canBuild: false }); MyObject.canBuild; // false o = MyObject.create();
In other words, this creates static properties and functions for the class. These are only available on the class and not on any instance of that class.
const Person = Ember.Object.extend({ name: '', sayHello() { alert(`Hello. My name is ${this.get('name')}`); } }); Person.reopenClass({ species: 'Homo sapiens', createPerson(name) { return Person.create({ name }); } }); let tom = Person.create({ name: 'Tom Dale' }); let yehuda = Person.createPerson('Yehuda Katz'); tom.sayHello(); // "Hello. My name is Tom Dale" yehuda.sayHello(); // "Hello. My name is Yehuda Katz" alert(Person.species); // "Homo sapiens"
Note that species
and createPerson
are not valid on the tom
and yehuda
variables. They are only valid on Person
.
