完整的 Web Worker 实例代码
我们已经看到了 .js 文件中的 Worker 代码。下面是 HTML 页面的代码：
<!DOCTYPE html>
<html>
<body>
Count numbers: <output id="result"></output>
<button onclick="startWorker()">Start Worker</button>
<button onclick="stopWorker()">Stop Worker</button>
<script>
var w;
function startWorker()
{
if(typeof(Worker)!=="undefined")
{
if(typeof(w)=="undefined")
{
w=new Worker("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();
}
</script>
</body>
</html>
