如何在Aurelia中发出自定义属性的信号？

import { bindable } from 'aurelia-framework';

export class MyComponent {
  @bindable customProperty;
}

import { EventAggregator } from 'aurelia-event-aggregator';
import { inject } from 'aurelia-framework';

@inject(EventAggregator)
export class MyComponent {
  @bindable customProperty;

  constructor(eventAggregator) {
    this.eventAggregator = eventAggregator;
  }

  publishCustomEvent() {
    this.eventAggregator.publish('CustomEvent', this.customProperty);
  }
}

import { EventAggregator } from 'aurelia-event-aggregator';
import { inject } from 'aurelia-framework';

@inject(EventAggregator)
export class AnotherComponent {
  constructor(eventAggregator) {
    this.eventAggregator = eventAggregator;
    this.subscription = this.eventAggregator.subscribe('CustomEvent', customProperty => {
      // 处理自定义属性的信号
      console.log(customProperty);
    });
  }

  detached() {
    // 在组件销毁时取消订阅
    this.subscription.dispose();
  }
}
