我无法正确理解你的问题！！

Provide code!

也许你正在寻找这样的东西：

var EventEmitter = require('events').EventEmitter;

var server = new EventEmitter();

server.on('foo', function() {
  console.log('got foo');
});

server.emit('foo');

检查这个拉：

Answer 2

您可以像这样从 JavaScript 发送 React Native 事件：

import { NativeEventEmitter, NativeModules } from "react-native";

const nativeEventEmitter = new NativeEventEmitter(NativeModules.Emitter);
nativeEventEmitter.emit("Event Name");
