html5之Web Workers示例

Web Workers使得html5也可以使用类似后台异步化、线程化的操作，让假死、卡不再存在，非常适合httpreqeust/io等操作。示例如下：

x.htm

<html>
<head>
<title>Web Workers</title>
</head>
<body>
<div class="page">
<div class="article">
  <h2 class="topic"><strong );
    worker.onmessage = function(event){
        document.getElementById('result').innerHTML = event.data;
    };
    worker.onerror = function(event){
        alert('Worker error:'+error.message+'\n');
        throw error;
    };
    worker.postMessage('35');
};
wt();
</script>
</html>

x.js:

var fibonacci2 = function(n){
    var i2 = 0;
    var fb2 = function(n){
        return n<2?n:arguments.callee(n-1)+arguments.callee(n-2);
    };
    return fb2(n);
};

var onmessage = function(event){
var n = parseInt(event.data,10);
postMessage(fibonacci2(n));
};
