用 onmoseover与onmoseout来实现,把那个框做成一个隐含的区,当书标移上去时,就把那个隐含的区进行显示,如果移开时把div区的属性改成hidden就可以了,
你要的框可以通过一个button 改改css来实现。

    <html>
    <head>
    <title>
    </title>
    </head>
    <body>
    <script language="javascript">
    function lookatme()
    {
    document.all.lookat.innerHTML='<input type="button" name="button1" value="lookat this this will..."  style="border:1px window-inset #000000">';
    }function nolook()
    {
    document.all.lookat.innerHTML="";
    }</script>
    <form name="form1">
    <a href="#" onmouseover="javascript:lookatme()" onmouseout="javascript:nolook()">go</a>
    <div background="#99CCFF">
    <font id="lookat">&nbsp;</font>
    </div></div>
    </form>
    </body>
    </html>

    你的有点问题,如果我再添加多一个链接,但提示框总在弟一个链接上<center>
    <a href="#"  onmouseover="javascript:lookatme();" onmouseout="javascript:nolook()">go</a>
    </center>
    <div background="#99CCFF" id="d1" >
    <font id="lookat">&nbsp;</font></div>

    直接用title实现的。<a href = "http://www.baidu.com" title="百度中国">baidu</a>
    用层实现的。
    你可以自己做出很多效果啊。demo.htm<script src="poptext.js"></script>
