我们再来看下其他小伙伴是如何实现的
<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。

<script type="text/javascript">
function dianji(){
x=document.getElementById("xian");
x.style.display="block";
return false;
}
function guanbi(name){
var c=document.getElementById("wangyan").value;
if(c==3){
x.style.display='none';
return false;
}
}
</script>
</body>
