使用Typescript实现Knockout组件依赖注入

import * as ko from 'knockout';

// 定义依赖注入容器
class DependencyContainer {
  private dependencies: { [key: string]: any } = {};

  // 注册依赖
  register(name: string, dependency: any) {
    this.dependencies[name] = dependency;
  }

  // 解析依赖
  resolve<T>(name: string): T {
    if (this.dependencies.hasOwnProperty(name)) {
      return this.dependencies[name];
    }
    throw new Error(`Dependency '${name}' not found.`);
  }
}

// 创建全局的依赖注入容器
const container = new DependencyContainer();

// 注册Knockout到容器中
container.register('ko', ko);

import * as ko from 'knockout';
import { container } from './DependencyInjection';

// 定义一个需要依赖注入的Knockout组件
class MyComponent {
  private ko: KnockoutStatic;

  constructor() {
    // 使用容器解析Knockout依赖
    this.ko = container.resolve<KnockoutStatic>('ko');
  }

  // 组件的其他代码...
}

// 注册组件到Knockout中
ko.components.register('my-component', {
  viewModel: MyComponent,
  template: '<div>My Component</div>'
});
