通信方法：

(1) 发送消息
主线程：worker.postMessage()
子线程：self.postMessage()
(2) 接收消息
主线程：worker.onmessage()
子线程：self.onmessage()
(3) 监听异常
主线程：worker.onerror()
子线程：self.onerror()
(4) 销毁方法
主线程：worker.terminate()
子线程：self.close()
(5) 加载脚本 (worker内部加载其他脚本)
importScripts('script1', 'script2')

// 主进程
<template><div class="menu-contain card"><el-button type="primary" @click="handlerSendMsg">Send</el-button></div>
</template><script setup lang="ts">
import { ref } from 'vue';const worker = ref()worker.value = new Worker(new URL('@/workers/handlerArrWorker.ts', import.meta.url))worker.value.onmessage = (res: any) => {console.log(res, 'res')
}const handlerSendMsg = () => {worker.value.postMessage({msg: 'start'})console.log(worker.value, 'worker.value')
}
</script><style scoped lang="scss"></style>

 

// 子进程
self.onmessage = () => {let list = []for (let index = 0; index < 1000000; index++) {list.push(Date.now())}self.postMessage(list)
}
