我的任务
分享看看这段JAVASCRIPT代码
<HTML>
<HEAD>
<TITLE>Timeout Program</TITLE>
<SCRIPT LANGUAGE="JavaScript">
<!--
function setTimer(){
timer = setTimeout("alert('Too Slow!')",10000)
};
function clearTimer(){
clearTimeout(timer)
alert("Congradulations!")
};
//-->
</SCRIPT>
</HEAD>
<BODY>
<SCRIPT LANGUAGE = "JavaScript"><!--
SetTimer()
//-->
</SCRIPT>
<FORM>
<INPUT TYPE="BUTTON" VALUE = "Click here within ten second."
ONCLICK = "clearTimer()">
</FORM>
</BODY>
</HTML>
我照着书抄得，怎么没有效果，没有跳出TOO SLOW的对话框
