Let's take a look at one of the simplest examples, which implements the display and hidden layers

The code is as follows Copy Code

<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";
};


Below is the closed layer, in fact, the principle is the same just add a effect.

The code is as follows Copy Code

<! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 transitional//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
<meta http-equiv= "Content-type" content= "text/html; Charset=utf-8 "/>
<title> Untitled Document </title>
<style type= "Text/css" >
body{position:relative;}
wang{width:100%; height:100% background: #CCC; display:none; z-index:10; position:fixed; top:0px; left:150px; margin : 0 auto; Left:inherit; Padding:0;filter:alpha (opacity=60); * * for IE browser transparency * *
opacity:0.6; * * For the FF browser transparency */}
. Wang ul{width:100px; height:100px; margin:0 auto;
</style>

<body>
<a onclick= "Dianji ()" > Eject </a><input type= "text"/>
<div class= "Wang" id= "Xian" onclick= "Guanbi ()" ><ul><form><label> name </label><input Id= "Wangyan" type= "text"/><br/><label> password </label><button style= "width:100px; height:100px "onclick=" Guanbi (this) > Close </button></form></ul></div>
<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>
