bsl/utils/system/findPage.ts

基于React的框架和UI组件

import { appData } from '../../app/core';
// import PageComponent from '../app/PageComponent';

type InstanceoPage<T> = T extends new (...args: any) => infer R ? R : undefined;

export default function findPage<T extends Function>(Page: T): InstanceoPage<T> | undefined {
  return appData.pages.find((item) => item instanceof Page) as InstanceoPage<T> | undefined;
}
