I tried to get to work some sort of:
export class SomeComponent {
constructor() {
let className: string = "TheClass";
/* should be the same as .. = new TheClass() */
let superSpecial = new className();
}
}
I have not yet figured out how to do this? Could anyone help me?
There are a few ways to do this. If your class is in a separate module:
SomeClass.ts
export class SomeClass {
constructor(arg: string) {
console.log(arg);
}
}
App.ts
import * as s from "./SomeClass";
var instance = new s["SomeClass"]("param");
Or using namespaces:
namespace Test {
export class SomeClass {
constructor(arg: string) {
console.log(arg);
}
}
}
var instance = new Test["SomeClass"]("param");
This will work for you
export class SomeComponent {
constructor() {
// suppose TheClass is the imported class name you want to instantiate
let className: typeof TheClass = TheClass;
/* should be the same as .. = new TheClass() */
let superSpecial = new className(); // you "new" it as normal
}
You should use square bracket notation:
const classNameStr = 'example';
const myStore = {example: class {}};
const init = new myStore[classNameStr]();
// Or in case you class si global
const classNameStr = 'example';
(window as any).example = class {}; // if your class is already global this line should be deleted. I have put it here just to make the example work
const init = new window[classNameStr]();
Or Eval:
eval(`new ${className}()`);
TheClass is a global constructor
