首先给大家展示演示效果:

遮罩层点击按钮弹出并且具有拖动和关闭效果(两种方法)

基于JavaScript的网页弹出层,鼠标按在弹出层的标题栏处,可以拖动该浮动层随意移动位置,不需要时也可以关闭,操作体验舒服,兼容性好,IE/火狐等众多浏览器下运行稳定、反应快速。代码表现方面,简洁务实,不玩虚的,拿去学习也相当不错。

js代码

示例一:


<!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 "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><span id="close">×</span></h2>

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

         jq代码:

  代码示例二:

<!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="/UploadFiles/2021-04-02/jquery-1.4.2.min.js">

以上通过jq和js分别实现了遮罩层点击按钮弹出并且具有拖动和关闭效果,希望对大家有所帮助。
