Let’s take a look at how other friends achieved it
<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>Example 3:
Let’s look at the simplest example first, which can show and hide layers
<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";
};
The following is a closed layer. In fact, the principle is the same, but an effect is added.
