捕获Angular2中的所有可点击元素？

1）如果要向具有(click)处理程序的所有元素添加某些行为，则可以创建如下指令：

@Directive({
  selector: '[click]',
  host: {
    'style': 'cursor: pointer' // or class
  }
})
export class ClickableDirective {}

2）要捕获所有具有click处理程序的元素，我会覆盖EventManager

import { Injectable, Inject, NgZone }      from '@angular/core';
import { EventManager, EVENT_MANAGER_PLUGINS } from '@angular/platform-browser';

@Injectable()
export class MyEventManager extends EventManager {
  constructor(@Inject(EVENT_MANAGER_PLUGINS) plugins: any[], private zone: NgZone) {
    super(plugins, zone);
  }

  addEventListener(element: HTMLElement, eventName: string, handler: Function): Function {
    if(eventName === 'click') {
      element.style.cursor = 'pointer'; // or add class
    }

    return super.addEventListener(element, eventName, handler);
  }
}

app.module.ts

  ...
  providers: [
    { provide: EventManager, useClass: MyEventManager }
  ]
})
export class AppModule {
