我在官方网站上看到他们说的 boxover 用法：1、head 里包含.js<script type="text/javascript" src="boxover.js"></script>
2、html元素里使用title属性<div title="header=[header text] body=[body text]" style="border: #558844 1px solid; width:200px; height: 75px">
My div with some text inside. Move over me to see my tooltip.
</div>
<input type="button" value="showBoxover" title="header=[标题] body=[这是一个按钮]" />
ie和firefox都没有达到预期的效果，而且还报错，‘top.get_help_tit is not a function’.怎么弄的哦？

2、function func(param1,param2)
{
param1+=100;
param2+=100;
alert(param1);
}param1是在另一个函数中声明的变量：function f()
{
var param1=0;
//...
}每次alert 都显示 100；不能改变 param1的值啊 ？ 怎么传引用啊？要能改变值的。
谢谢了啊 。不好意思我在一个帖子里又问了2个和帖子不相关的问题。
