绑定事件的写法不是你那样的，按照我下面的方式来写，用匿名方法
<html>
<head>
<title>一个时钟</title>
<script type="text/javascript">
window.onload = function () {
var today = new Date();
var h = today.getHours();
var m = today.getMinutes();
var s = today.getSeconds();
// add a zero in front of numbers<10
m = checkTime(m);
s = checkTime(s);
document.getElementById('txt').innerHTML = h + ":" + m + ":" + s;
t = setTimeout('startTime()', 500);
}
function checkTime(i) {
if (i < 10) {
i = "0" + i;
}
return i;
};
</script>
</head>

<div id="txt"></div>

其实你把window.onload = startTime();
改为window.onload = startTime;
就好了
不要那个括号
改为window.onload = startTime;
就好了
不要那个括号
