动态创建JS WORKER

window.URL = window.URL || window.webkitURL;
const response = `self.onmessage = ({ data: { data } }) => {
  const {method} = data;
  self.postMessage(method.replace("吗",""));
}`;
const blob = new Blob([response],{ type: "application/javascript" });
const work = new Worker(URL.createObjectURL(blob));
work.onmessage = function (e) {
 //  speechSynthesis.speak(new SpeechSynthesisUtterance(e.data))
  alert(`Response: ${JSON.stringify(e)}`);
//   URL.revokeObjectURL(url);//释放内存
//   worker.terminate();
};
worker.postMessage({
  method: "吃饭了吗"
});
