Wonder if anyone can help?
I'm trying to call a parent's constructor or at a minimum get a reference to the parent class in some way without hardcoding anything.
class A {
static foo(options) {
parent::__construct(options); <- this is how you would get the parent in php
}
}
class B extends A {
}
Is this possible?
In a javascript class (and OOP in general), a static method is not part of an instance and therefore the object it resides in does not have a constructor.
You should avoid using static method for this sort of thing and use a standard constructor and call super() to call the parent constructor.
class A {
constructor(options) {
console.log('Options are:');
console.log(options);
}
}
class B extends A {
constructor(options) {
super(options);
}
}
const item = new B({item1: 'abc'});Further reference: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/super
You can use super() to call parent constructor
class A {
constructor() {
console.log('I\'m parent ');
}
foo(){
console.log('Class A: Called foo');
}
}
class B extends A {
constructor() {
super();
}
foo(){
super.foo()
}
}
const b = new B();
b.foo();
super
