介绍一种弹出层效果的JS代码
：2010-10-13 23:41:55
本文介绍了一种在网页中弹出层的效果，下面直接给出了源代码：代码分两部分，html代码和JS源代码。
html代码：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>弹出层效果</title>
</head>
<script src = "openNewDiv.js"></script>
<body>
<a href="#" onclick="openNewDiv('newDiv');return false;">激活新层</a>
<p>网页内容</p>
</body>
</html>
js代码：
var docEle = function() {
return document.getElementById(arguments[0]) || false;
}
function openNewDiv(_id) {
var m = "mask";
if (docEle(_id)) document.removeChild(docEle(_id));
if (docEle(m)) document.removeChild(docEle(m));
// 新激活图层
var newDiv = document.createElement("div");
newDiv.id = _id;
newDiv.style.position = "absolute";
newDiv.style.zIndex = "9999";
newDiv.style.width = "300px";
newDiv.style.height = "200px";
newDiv.style.top = "160px";
newDiv.style.left = (parseInt(document.body.scrollWidth) - 300) / 2 + "px"; // 屏幕居中
newDiv.style.background = "#EFEFEF";
newDiv.style.border = "1px solid #860001";
newDiv.style.padding = "5px";
newDiv.innerHTML = "新激活图层内容";
document.body.appendChild(newDiv);
// mask图层
var newMask = document.createElement("div");
newMask.id = m;
newMask.style.position = "absolute";
newMask.style.zIndex = "1";
newMask.style.width = document.body.scrollWidth + "px";
newMask.style.height = document.body.scrollHeight + "px";
newMask.style.top = "0px";
newMask.style.left = "0px";
newMask.style.background = "#000";
newMask.style.filter = "alpha(opacity=40)";
newMask.style.opacity = "0.40";
document.body.appendChild(newMask);
// 关闭mask和新图层
var newA = document.createElement("a");
newA.href = "#";
newA.innerHTML = "关闭激活层";
newA.onclick = function() {
document.body.removeChild(docEle(_id));
document.body.removeChild(docEle(m));
return false;
}
newDiv.appendChild(newA);
}
