如何才能做出像榕树下这种效果的------Alt????????????????

Question

它的HTC文件没有下载下来，不过相信原理是差不多的，颜色你可以自己调一下
<script>
function ex(n){Expository1.innerHTML=n;Expository1.style.top=event.clientY+20
if(event.clientX>document.body.clientWidth-172)Expository1.style.left=document.body.clientWidth-250
else if(event.clientX<81)Expository1.style.left=0
else Expository1.style.left=event.clientX-80;Expository1.style.visibility="visible"}
function ex1(){Expository1.style.visibility="hidden"}
</script>
<div id=Expository1 style="position:absolute;z-index:2;width:250;border-style:double;border-color:#FF66FF;background-color:#f0f8ff; visibility:hidden" align=left></div><a href="http://www.csdn.net" onmouseover="ex('...  林诺然 ［1］我的生活 我叫林，在上海这个繁华冷漠的城市生活了20年。在我的生活中 ...')" onmouseout=ex1()>显示说明</a>

Answer 1

<PROPERTY NAME="son" />
<ATTACH EVENT="onmouseover" ONEVENT="onit()" />
<ATTACH EVENT="onmousemove" ONEVENT="onit()" />
<ATTACH EVENT="onmouseout" ONEVENT="noit()" />
<SCRIPT>function onit() {
var oSon=window.document.getElementById(son);
if (oSon==null) return;
with (oSon) {
innerText=alt;
style.display="block";
style.pixelLeft=window.event.clientX+window.document.body.scrollLeft+6;
style.pixelTop=window.event.clientY+window.document.body.scrollTop+9;
}
}function noit() {
var oSon=window.document.getElementById(son);
if (oSon==null) return;
oSon.style.display="none";
}</SCRIPT>
将上述代码存成xx.htc，然后调用<span style="behavior:url(xx.htc)">

Answer 2

不用<div>上面的大侠请给一下调用的具体代码。
