The example in this article describes how to use JavaScript to achieve the click switching effect of multiple overlapping layers. Share it with everyone for your reference. The details are as follows:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>三个层重叠，点击可切换</title>
<script type="text/javascript">
function $(obj){
return document.getElementById(obj);
}
function change(n){
for (var i=1;i<4;i++){
if(n==i){
$("a"+i).style.zIndex="100";
}else{
$("a"+i).style.zIndex="0";
}
}
}
</script>
</head>
<body>
<div id="a1"
style="position:absolute;left:100px;top:100px;width:100px;height:100px;
background-color:#ddeeff;z-index:1" onclick="change('1')" >
</div>
<div id="a2"
style="position:absolute;left:150px;top:130px;width:100px;height:100px;
background-color:#eeffdd;z-index:2" onclick="change('2')">
</div>
<div id="a3"
style="position:absolute;left:200px;top:160px;width:100px;height:100px;
background-color:#ffddee;z-index:3" onclick="change('3')">
</div>
<div>http://www.jb51.net/</div>
</body>
</html>I hope this article will be helpful to everyone’s JavaScript programming design.
