I created this sample code to demonstrate what I’m trying to do. Run this code.
Cannot read property ‘myValue’ of undefined
class Foo {
myValue = 'test123';
boo: Boo;
constructor(boo: Boo) {
this.boo = boo;
}
memoFunc() {
this.boo.anotherFunction(this.myFunction);
}
myFunction() {
console.log(this.myValue);
}
}
class Boo {
anotherFunction(func: () => void) {
func();
}
}
const foo = new Foo(new Boo());
foo.memoFunc();
You need to either use
bind
or use anarrow function
to get the correctthis
value.Bind :-
Arrow function :-
