點評：很多人在測試worker api的時候，總是會出現異常，根本測試不到效果，需要注意的是就是單純的文本文件是實現不了worker的，你寫的實際代碼 必須部署到服務器（tomcat.jBoss等）才能運行worker api
很多人在測試worker api的時候，總是會出現異常，根本測試不到效果。復制代碼
代碼如下:
function messageHandler(e) {
postMessage("worker says: " + e.data + " too");
}
addEventListener("message", messageHandler, true);
postMessage("2222222222");
復制代碼
代碼如下:
<!DOCTYPE html>
<html>
<head>
<title>index.html</title>
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="this is my page">
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<!--<link type="text/css" href="./styles.css">-->
</head>
<body>
<script type="text/javascript">
if(typeof(Worker)!=="undefined"){
console.log("zhichi worke");
}else{
console.log("no support!");
}
function messageHandler(e){
console.log(e.data);
}
function errorHandler(e){
console.log(e.message, e);
}
var myWorker = new Worker("task.js");
myWorker.addEventListener("message", messageHandler, true);
myWorker.addEventListener("error", errorHandler, true);
myWorker.postMessage("1 fangsong d");
</script>
</body>
</html>
