<html><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312" /><title>oec2003</title><script language="JavaScript" type="text/JavaScript"><!--function toggle(targetid){ if (document.getElementById){ target=document.getElementById(targetid); if (target.style.display=="block"){ target.style.display="none"; } else { target.style.display="block"; } }}--></script><style type="text/css"><!--#div1{background-color:#000000;height:400px;width:400px;display:none;}--></style></head><body><input type="button" id="butn" value="显示/隐藏" onclick="toggle('div1')" /><center><div id="div1"></div></center>居中的DIV</body></html>示例三：
先来看一个最简单的实例,这个可以实现显示和隐藏层
<div id="text"></div><input type="button" onclick="display('text')" />function $_(id){ return document.getElementById(id);};function display(x){ $(x).style.display=($(x).style.display=="none")?"":"none";};下面是关闭层，其实原理 是一样的只是加了个效果。
