晕，不用继续setTimeOut也可以执行。
可是我希望它能回到原函数，就是率先执行完所有setTimeout()之后，再回到Test（）里面执行
document.getElementsByTagName("p")[5].innerHTML='I do not know'
这有什么解决办法呢？
我在Dreamweaver上试了不行诶
LZ,你这个语句已经执行完毕了啊，5个settimeout语句执行后，就执行下面语句了，但是因为页面还没加载完毕，所以无法获得相关的p节点，而settimeout在分别1秒-5秒后执行其中的函数，此时页面已经加载完毕，你可以把上述代码放到window.onload中，即window.onload = test;

<title>For Test</title>
<script type="text/javascript" language="javascript">
//<![CDATA[
function count(text, index) { //你的参数名太乱太随意了
document.getElementsByTagName('P')[index].innerHTML = text;
}function test() { //方法名开头字母最好小写
//setTimeout("count("+"'Long time no see'"+","+0+")", 1000);
setTimeout(function(){count('Long time no see', 0);}, 1000);
//setTimeout("count("+"'Hello every one'"+","+1+")", 2000);
setTimeout(function(){count('Hello every one', 1);}, 2000);
//setTimeout("count("+"'My Enghish name is Clay'"+","+2+")", 4000);
setTimeout(function(){count('My Enghish name is Clay', 2);}, 4000);
//setTimeout("count("+"'You can call me Claycao'"+","+3+")", 6000);
setTimeout(function(){count('You can call me Claycao', 3);}, 6000);
//setTimeout("count("+"'Nice to meet you'"+","+4+")", 8000);
setTimeout(function(){count('Nice to meet you', 4);}, 8000);
var ps = document.getElementsByTagName('P');
ps[5].innerHTML = 'I don\'t know'; //编码风格不统一，字符串要么用单引号（建议用'）括起来，要么用双引号，别混着用
}window.onload = function() {
test(); //当文档载入完成后（或者更好的方法是dom构建完成后）再对dom进行操作
};
//]]>

另外多说一句：Javascript 里 setTimeout 相当于创建了一个新的线程，这个线程会在你指定的时间间隔后自动开始运行，setTimeout 调用后会马上返回，不会等第一个参数中的代码执行完后再返回，所以不要滥用 setTimeout，你还是没明白 setTimeout 的作用。
