推荐答案
@Hexagon理论：为什么你会永远改写整个头部元素只是改变一个元素在头上的价值？您的解决方案是在多个层次上效率极其低下。
@Hexagon Theory: Why would you ever rewrite the whole head element just to change the value of one element in the head? Your solution is horribly inefficient on multiple levels.
<html>
<head>
<link rel="icon" href="on.png" type="image/png" id="changeMe" />
<script type="text/javascript" src="flash.js"></script>
</head>
<body>
</body>
</html>
flash.js：
flash.js:
function Flasher(speed) {
var elem = document.getElementById('changeMe');
this.timer = setTimeout(function() {
elem.href = elem.href == 'on.png' ? 'off.png' : 'on.png';
}, speed);
this.stop = function() { clearTimeout(this.timer); }
}
/* sample usage
*
* var flasher = new Flasher(1000);
* flasher.stop();
*/
它并没有真的要一个类，但它有助于保持全局命名空间的清洁。这是未经测试，但如果简单地改变HREF出于某种原因不能正常工作，克隆链接节点，改变href和替换克隆一个旧的链接。
It didn't really have to be a class but it helped keep the global namespace clean. That's untested but if simply changing the href doesn't work for some reason, clone the link node, change the href and replace the old link with the cloned one.
