关于html5的webworker的简单示例

先不废话了，具体webworker是干什么用的自己拿baidu google去。以下仅是一个示例：

webworker1.js：

var n = 1;
search: while (true) {
    n += 1;
    for (var i = 2; i <= Math.sqrt(n); i += 1) {
        if (n % i == 0) {
            continue search;
        }
    }
    // found a prime!
    postMessage(n);
}

webworker2.js：

var test = 1;
search: while (true) {
    test += 10;
    for (var i = 2; i <= Math.sqrt(test); i += 1) {
        if (test % i == 0) {
            continue search;
        }
    }
    // foutestd a prime!
    postMessage(test);
}
