Web Workers 一次任务然后就关闭了。
var w; function startWorker()
{
if(typeof(Worker)!=="undefined")
{
if(typeof(w)=="undefined")
{
w=new Worker("/example/html5/demo_workers.js");
}
w.onmessage = function (event) {
document.getElementById("result").innerHTML=event.data;
};
}
else
{
document.getElementById("result").innerHTML="Sorry, your browser does not support Web Workers...";
}
} function stopWorker()
{
w.terminate();
}
Server-Sent 事件 - 单向消息传递
Server-Sent 事件指的是网页自动获取来自服务器的更新。
var source=new EventSource("demo_sse.php");
source.onmessage=function(event)
{
document.getElementById("result").innerHTML+=event.data + "<br />";
};
