EventBus.$on似乎没有捕捉到正在发出的事件。(Vue js)

// EventBus.js
import Vue from 'vue';
export const EventBus = new Vue();

// 在组件A中触发事件
import { EventBus } from './EventBus.js';
export default {
  methods: {
    doSomething() {
      EventBus.$emit('my-event', 'some data');
    }
  }
}

// 在组件B中监听事件
import { EventBus } from './EventBus.js';
export default {
  created() {
    EventBus.$on('my-event', this.handleMyEvent);
  },
  methods: {
    handleMyEvent(data) {
      console.log('Event received with data:', data);
    }
  },
  beforeDestroy() {
    // 组件销毁前移除事件监听器
    EventBus.$off('my-event', this.handleMyEvent);
  }
}
