这里有新鲜出炉的Javascript教程，程序狗速度看过来！
JavaScript客户端脚本语言
Javascript 是一种由Netscape的LiveScript发展而来的原型化继承的基于对象的动态类型的区分大小写的客户端脚本语言，主要目的是为了解决服务器端语言，比如Perl，遗留的速度问题，为客户提供更流畅的浏览效果。
如下所示：
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<style type="text/css">
.toopTip
{
background-color:Yellow;
border-style:solid;
border-width:1px;
border-color:Red;
}
</style>
<script language="javascript" type="text/javascript">
/*
如果希望提示的div的左边界与上边界与显示的div重叠，那么需要删除文档头W3C标准
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
*/
function initEvent() {
var divArray = document.getElementsByTagName("div");
for (var i = 0; i < divArray.length; i++) {
divArray[i].onmouseover = createDivDetailOne;
/*
无法用原始的div绑定鼠标移走的事件,因为明细的div的宽度长度都要大于原始div，
这样原始的div就被覆盖了，此时会自动触发onmouseout事件
*/
//divArray[i].onmouseout = removeDivDetail;
}
}
function createDivDetailOne() {
//保证divDetail div的唯一性
var divDetail = document.getElementById("divDetail");
if(divDetail)
{
document.body.removeChild(divDetail);
}
divObj = document.createElement("div");
divObj.className = "toopTip";
divObj.setAttribute("id", "divDetail");
divObj.style.position = "absolute";
divObj.style.width = "200px";
divObj.style.height = "100px";
var triggerObj = window.event.srcElement;
divObj.style.top = triggerObj.offsetTop;
divObj.style.left = triggerObj.offsetLeft;
divObj.innerHTML = triggerObj.innerText;
document.body.appendChild(divObj);
//此时用于明细的div已经覆盖了原div，所以覆盖的div要进行事件的处理
document.getElementById("divDetail").onmouseout = function() {
divObj = this;
if (!divObj) {
return;
}
document.body.removeChild(divObj);
};
}
function removeDivDetail() {
var divObj = document.getElementById("divDetail");
if (!divObj) {
return;
}
document.body.removeChild(divObj);
}
window.onload = initEvent;
</script>
</head>
<body>
<div id="divOne" style="background-color: Fuchsia; width: 100px; height: 100px;" >

<div id="divTwo" style="background-color: Aqua; width: 100px; height: 100px">
