网页倒计时

刚才看setTimeout，就顺便做了个网页上的倒计时，弄来玩玩，代码如下：

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<script type="text/javascript">
var waitTime = 10;
function timeout(setTime) {
	if(setTime != null){
		waitTime = setTime;
	}
	document.body.innerHTML = waitTime;
	if (waitTime < 0) {
		waitTime = 10;
		document.body.innerHTML = '<input type="button" value="Click" onclick="timeout();" />';
		return;
	} else {
		waitTime--;
	}
	setTimeout("timeout()", 1000);
}

</script>
<title>Insert title here</title>
</head>
<body>
<input type="button" value="Click" onclick="timeout();" />
</body>
</html>
