First, let me show you the demonstration effect:

Web page pop-up layer based on JavaScript. Press the mouse on the title bar of the pop-up layer and you can drag the floating layer to move the position at will. It can also be closed when not needed. The operation experience is comfortable and the compatibility is good. IE/Firefox and many other It runs stably and responds quickly under the browser. In terms of code performance, it is concise and pragmatic, not frivolous, and is quite good for learning.

js code

Example 1:


<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>弹出层并可拖拽</title>
<style>
html,body{height:100%;overflow:hidden;}
body,div,h2{margin:0;padding:0;}
body{font:12px/1.5 Tahoma;}
li{ list-style-type:none}
center{padding-top:10px;}
button{cursor:pointer;}
#overlay{position:absolute;top:0;left:0;width:100%;height:100%;background:#000;opacity:0.5;filter:alpha(opacity=50);display:none;}
#win{position:absolute;top:50%;left:50%;width:400px;height:200px;background:#fff;border:4px solid #f90;margin:-102px 0 0 -202px;display:none;}
h2{font-size:12px;height:18px;text-align:right;background:#FC0;border-bottom:3px solid #f90;padding:5px;cursor:move;}
h2 span{color:#f90;cursor:pointer;background:#fff;border:1px solid #f90;padding:0 2px;}
</style>
<script>
window.onload = function ()
{
var oWin = document.getElementById("win");
var oLay = document.getElementById("overlay");
var oBtn = document.getElementsByTagName("button")[0];
var oClose = document.getElementById("close");
var oH2 = oWin.getElementsByTagName("h2")[0];
var bDrag = false;
var disX = disY = 0;
oBtn.onclick = function ()
{
oLay.style.display = "block";
oWin.style.display = "block"
};
oClose.onclick = function ()
{
oLay.style.display = "none";
oWin.style.display = "none"
};
oClose.onmousedown = function (event)
{
(event || window.event).cancelBubble = true;
};
oH2.onmousedown = function (event)
{
var event = event || window.event;
bDrag = true;
disX = event.clientX - oWin.offsetLeft;
disY = event.clientY - oWin.offsetTop;
this.setCapture && this.setCapture();
return false
};
document.onmousemove = function (event)
{
if (!bDrag) return;
var event = event || window.event;
var iL = event.clientX - disX;
var iT = event.clientY - disY;
var maxL = document.documentElement.clientWidth - oWin.offsetWidth;
var maxT = document.documentElement.clientHeight - oWin.offsetHeight;
iL = iL < 0 &#63; 0 : iL;
iL = iL > maxL &#63; maxL : iL;
iT = iT < 0 &#63; 0 : iT;
iT = iT > maxT &#63; maxT : iT;
oWin.style.marginTop = oWin.style.marginLeft = 0;
oWin.style.left = iL + "px";
oWin.style.top = iT + "px";
return false
};
document.onmouseup = window.onblur = oH2.onlosecapture = function ()
{
bDrag = false;
oH2.releaseCapture && oH2.releaseCapture();
};
};
</script>
<meta charset="utf-8">
</head>
<body>
<div id="overlay"></div>
<div id="win"><h2 id="span-id-close-span"><span id="close">×</span></h2>
<li><a href='http://www.100sucai.com' target='_blank'>http://www.100sucai.com</a></li>

</div>
<center><button>弹出层</button></center>
</body>
</html><br />

jq code:

Code example two:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>jQuery弹出层效果</title>
<meta content="网页特效,特效代码,jQuery,css特效,Js代码,广告幻灯,图片切换" name="keywords" />
<meta content="jQuery弹出层效果，有关闭按钮，代码简单易懂，你可以随意修改弹出层的参数。" name="description" />
<script src="/uploads/common/js/jquery-1.4.2.min.js" type="text/javascript"></script>
<style>
.black_overlay{
display: none;
position: absolute;
top: 0%;
left: 0%;
width: 100%;
height: 100%;
background-color: black;
z-index:1001;
-moz-opacity: 0.8;
opacity:.80;
filter: alpha(opacity=80);
}
.white_content {
display: none;
position: absolute;
top: 10%;
left: 10%;
width: 80%;
height: 80%;
border: 16px solid lightblue;
background-color: white;
z-index:1002;
overflow: auto;
}
.white_content_small {
display: none;
position: absolute;
top: 20%;
left: 30%;
width: 40%;
height: 50%;
border: 16px solid lightblue;
background-color: white;
z-index:1002;
overflow: auto;
}
</style>
<script type="text/javascript">
//弹出隐藏层
function ShowDiv(show_div,bg_div){
document.getElementById(show_div).style.display='block';
document.getElementById(bg_div).style.display='block' ;
var bgdiv = document.getElementById(bg_div);
bgdiv.style.width = document.body.scrollWidth;
// bgdiv.style.height = $(document).height();
$("#"+bg_div).height($(document).height());
};
//关闭弹出层
function CloseDiv(show_div,bg_div)
{
document.getElementById(show_div).style.display='none';
document.getElementById(bg_div).style.display='none';
};
</script>
</head>
<body>
<input id="Button1" type="button" value="点击弹出层" onclick="ShowDiv('MyDiv','fade')" />
<!--弹出层时背景层DIV-->
<div id="fade" class="black_overlay">
</div>
<div id="MyDiv" class="white_content">
<div style="text-align: right; cursor: default; height: 40px;">
<span style="font-size: 16px;" onclick="CloseDiv('MyDiv','fade')">关闭</span>
</div>
目前来说，我还是喜欢这个自己改造的弹出层。自己在项目中也用的是这个。
</div>
</body>
</html>

The above uses jq and js to realize that the mask layer clicks the button to pop up and has drag and close effects. I hope it will be helpful to everyone.
