在js后台部分可以使用event.setParam('attributeName',attributeValue)方式对预装载的参数赋值。...触发事件(Fire Event):触发事件需要写在controller.js中,这里是MessageEventComponentController.js 当controller/helper js ...handlerInit : function(component, event, helper) { console.log('execute init'); var messageEvent...= component.getEvent('componentEvent'); messageEvent.setParam('message','testAfterUpdate');...messageEvent.fire(); }, handlerMessageChange : function(component,event,helper) {
所以,当一些低优先级但是耗时的任务 (日志处理) 正在执行时,一些高优先级的任务 (业务相关) 就只能等着,可能导致 UI 交互不流畅,浏览器出现卡顿的情况,对于 CPU 来说,JS 单线程的带来的不便就更加明显了...(ps:这里并不是说 JS 本身支持了多线程的能力,只是浏览器作为宿主环境提供了 JS 一个多线程运行的环境) W3C 定义:A web worker is a JavaScript that runs...WorkerReportType.ReadEventTblStart, data: count }); // 主线程监听来自 Worker 的消息 worker.onmessage = (event: MessageEvent...break; case ... } } Worker 线程 // Worker 监听来自主线程的消息 self.onmessage = (event: MessageEvent) => {...也就是说,如果我们传输的是 JS 对象,需先将其转换为 ArrayBuffer,否则会报错。

worker的定义: interface Worker extends EventTarget, AbstractWorker { onmessage: ((this: Worker, ev: MessageEvent...) => any) | null; onmessageerror: ((this: Worker, ev: MessageEvent) => any) | null; postMessage...= document.querySelector('.result'); if (window.Worker) { const myWorker = new Worker("worker.js...'); /* imports just "foo.js" */ importScripts('foo.js', 'bar.js'); /* imports two...scripts */ importScripts('//example.com/hello.js'); /* You can import scripts from other origins */
unregister(MainActivity.this); } @Subscribe(threadMode = ThreadMode.MAIN) public void onMoonEvent(MessageEvent...tv_a.setText(message.getMessage()); } @Subscribe(sticky = true) public void onMoonEvents(MessageEvent...@Override public void onClick(View view) { EventBus.getDefault().postSticky(new MessageEvent...; finish(); } }); } } MessageEvent(事件类) public class MessageEvent { private String...message; public MessageEvent(String message) { this.message = message; } public MessageEvent
start(); } 使用EventBus的情况 EventBus的基本使用包含三个步骤: 定义事件 例子中下载内容就是一个String类型的字符串,可以简单定义: public class MessageEvent...Activity A是事件的消费者,在其中声明一个方法如下: @Subscribe(threadMode = ThreadMode.MAIN) public void showContent(MessageEvent...messageEvent){ showContentTv.setText(messageEvent.getMessage()); } 另外,还需要将Subscriber注册到EventBus...messageEvent=new MessageEvent(); messageEvent.setMessage("Hello World From Network")...; EventBus.getDefault().post(messageEvent); finish(); }
注册/取消订阅 发送事件 添加依赖 compile 'org.greenrobot:eventbus:3.0.0' 定义事件 这里的事件是一个任意的POJO 没有任何要求 public class MessageEvent...{ public final String message; public MessageEvent(String message) { this.message...订阅 准备订阅者 使用注解 @Subscribe ,在3.0中对方法名称没有任何要求 当发送事件时EventBus会调用方法 // This method will be called when a MessageEvent...// Called in the same thread (default) @Subscribe public void onEvent(MessageEvent event){ // Process...stickyEvent = EventBus.getDefault().getStickyEvent(MessageEvent.class); // Better check that an event
测试一下"); } } public class EventBusExample { public static void main(String[] args) { MessageEvent...messageEvent =new MessageEvent(1,"测试发布消息"); EventBus eventBus = new EventBus(); eventBus.register...(new EventListener()); // 注册 eventBus.post(messageEvent); //发送消息 } } /** * 其实这个类就是一个Bean...类,里面定义用来传输的数据的类型 */ @Data public class MessageEvent { private int type; private String message...; public MessageEvent(int type, String message) { this.type = type; this.message
示例:作为 EventEmitter 事件订阅发布使用,实现脚本间通信 /* one.js */ export default function (port) { port.onmessage/port.postMessage...} /* two.js */ export default function (port) { port.onmessage/port.postMessage } /* index.js */ import...one from 'one.js' import two from 'two.js' const { port1, port2 } = new MessageChannel() one(port1)... { return new Promise((resolve) => { ep.addEventListener("message", function l(ev: MessageEvent...obj: any, ep: Endpoint = self as any) { // ① ep.addEventListener("message", function callback(ev: MessageEvent
基本用法 引入Otto dependencies { compile 'com.squareup:otto:1.3.8' } 定义事件: public class MessageEvent { /*...Additional fields if needed */ } 订阅和取消订阅 bus.register(this); bus.unregister(this); 发布: bus.post(new MessageEvent...,并且方法的用 public 修饰的.方法名可以随意取,重点是参数,它是根据你的参数进行判断来自于哪个发送的事件 @Subscribe public void showEvent(MessageEvent...("非著名程序员")); finish(); } }); } @Produce public MessageEvent...produceMessageEvent() { return new MessageEvent("非著名程序员"); } // @Override // protected
delegate void MessageEventHandler(object sender, MyEventArgs e); public event MessageEventHandler MessageEvent...; public void OnMessage(MyEventArgs e) { if (this.MessageEvent !...= null) MessageEvent(this, e); } //要锁的变量,通过它可以看出2种锁在不同情况下的效果 private int num...button1_Click(object sender, EventArgs e) { LockTest test = new LockTest("LockTest 1"); test.MessageEvent...button2_Click(object sender, EventArgs e) { LockTest test = new LockTest("LockTest 1"); test.MessageEvent
订阅者 发布者就是 发送事件 订阅者 就是接收事件 gradle compile ‘org.greenrobot:eventbus:3.0.0’ 1.定义事件 public static class MessageEvent...// 定义事件 这个就是你要传送的数据实体类 2.准备订阅者 @Subscribe(threadMode = ThreadMode.MAIN) public void onMessageEvent(MessageEvent...) { super.onStop(); EventBus.getDefault().unregister(this); } 3.发送事件 EventBus.getDefault().post(new MessageEvent
二.EventBus的基本用法 1.自定义一个事件类(相当于我们平常所用的bean类) public class MessageEvent { ... } 2.在需要订阅的地方注册 EventBus.getDefault...().postSticky(messageEvent); 4.处理事件(eg.刷新UI) @Subscribe(threadMode = ThreadMode.MAIN) public void XXX...(MessageEvent messageEvent) { ... } 5.取消事件订阅 @Override protected void onDestroy() { EventBus.getDefault...1.导入3.0依赖 compile ‘org.greenrobot:eventbus:3.0.0’ 2.定义消息事件类 public class MessageEvent { public final...String uname; public final String upass; public MessageEvent(String name,String pass) { this.uname
