类: EventHandler

导入示例：

import { EventHandler } from "cc";

“EventHandler” 类用来设置场景中的事件回调，该类允许用户设置回调目标节点，目标组件名，组件方法名，并可通过 emit 方法调用目标函数。

example

// Let's say we have a MainMenu component on newTarget
// file: MainMenu.ts
@ccclass('MainMenu')
export class MainMenu extends Component {
    // sender: the node MainMenu.ts belongs to
    // eventType: CustomEventData
    onClick (sender, eventType) {
        cc.log('click');
    }
}

import { Component } from 'cc';
const eventHandler = new Component.EventHandler();
eventHandler.target = newTarget;
eventHandler.component = "MainMenu";
eventHandler.handler = "OnClick";
eventHandler.customEventData = "my data";
