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。
首先介绍的是一个div跟随鼠标移动的效果，具体代码如下

//
var scrollLeft = document.documentElement.scrollLeft || document.body.scrollLeft;
var scrollTop = document.documentElement.scrollTop || document.body.scrollTop;
div1.style.top = oEvent.clientY + scrollTop + 'px'; //Y
div1.style.left = oEvent.clientX + scrollLeft + 'px';//X
