html代碼：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>简jQuery左右对称浮动广告代码</title>
<link rel="stylesheet" href="css/style.css" />
</head>
<body>
<div style="height:2000px;"></div>
<!-- 代码部分begin -->
<div id="floatright" style="position: absolute; z-index: 10; "></div>
<script src="js/jquery.js" ></script>
<script src="js/floatAd.js" ></script>
<script>
window.onload = function(){
var ad2 = new FloatAd({
nodeLink : "<a href='广告连接地址'><img src='广告图片' border=0 /></a>" ,
floatObj : "floatleft",
x : 10,
y : 400,
locate : "left"
});
ad2.play();
}
</script>
<!-- 代码部分end -->
</body>
</html>
js檔除引入jquery外(要問我jquery是什麼，請出門左轉)還需要：
var FloatAd = function(obj){
var mainNode = $("." + obj.main)[0];
if(obj.nodeLink && (typeof obj.nodeLink == "string")){
var newFloatObj = document.createElement("div");
newFloatObj.id = obj.floatObj;
newFloatObj.style.position = "absolute";
newFloatObj.style.zIndex = 10;
newFloatObj.innerHTML = obj.nodeLink;
document.body.appendChild(newFloatObj);
}
this.ad = document.getElementById(obj.floatObj);
this.main = document.getElementById(obj.main)||mainNode;
this.x = obj.x;
this.y = obj.y;
this.locate = obj.locate;
this.space = obj.space;
var that = this;
this.play = function(){
setInterval(function(){
that.calculate();
},10);
};
}
FloatAd.prototype = {
constructor : FloatAd,
calculate : function(){
var obj_x = this.x,
obj_y = this.y,
main_offsetLeft = document.documentElement.scrollLeft||document.body.scrollLeft,
main_offsetTop = document.documentElement.scrollTop||document.body.scrollTop;
if(this.main){
if(this.locate == "left"){
obj_x = this.main.offsetLeft - this.ad.offsetWidth - this.space;
}else if(this.locate == "right"){
obj_x = this.main.offsetLeft + this.main.offsetWidth + this.space;
}
if(this.ad.offsetLeft != main_offsetLeft + obj_x){
var dx = (main_offsetLeft + obj_x - this.ad.offsetLeft)*0.08;
dx = (dx > 0 ? 1 : -1)*Math.ceil(Math.abs(dx));
this.ad.style.left = this.ad.offsetLeft + dx + "px";
}
}else{
if(this.locate == "left"){
this.ad.style.left = obj_x + "px";
}else if(this.locate == "right"){
this.ad.style.right = obj_x +"px";
}
}
if(this.ad.offsetTop != main_offsetTop + obj_y){
var dy = (main_offsetTop + obj_y - this.ad.offsetTop)*0.08;
dy = (dy > 0 ? 1 : -1)*Math.ceil(Math.abs(dy));
this.ad.style.top = this.ad.offsetTop + dy + "px";
}
}
}
這是自己在用到這種效果的時候整理出來的，copy網上的案例，進行整理，方便大家使用。
2 全螢幕漂浮案例：飄窗！
css檔：
#img1{
z-index: 100;
left: 2px;
width: 59px;
position: absolute;
top: 43px;
height: 61px;
visibility: visible;
}
html檔
<html> <head> <title>漂浮广告</title> </head> <link rel="stylesheet" href="floatImg.css"/> <body> <div id=img1> <a href="广告链接地址" target="_blank"> <img src="广告图片"> </a> </div> </body> <script src="链接js"></script> </html>
js程式碼：
var xPos = 300;
var yPos = 200;
var step = 1;
var delay = 30;
var height = 0;
var Hoffset = 0;
var Woffset = 0;
var yon = 0;
var xon = 0;
var pause = true;
var interval;
img1.style.top = yPos;
function changePos()
{
width = document.body.clientWidth;
height = document.body.clientHeight;
Hoffset = img1.offsetHeight;
Woffset = img1.offsetWidth;
img1.style.left = xPos + document.body.scrollLeft;
img1.style.top = yPos + document.body.scrollTop;
if (yon)
{yPos = yPos + step;}
else
{yPos = yPos - step;}
if (yPos < 0)
{yon = 1;yPos = 0;}
if (yPos >= (height - Hoffset))
{yon = 0;yPos = (height - Hoffset);}
if (xon)
{xPos = xPos + step;}
else
{xPos = xPos - step;}
if (xPos < 0)
{xon = 1;xPos = 0;}
if (xPos >= (width - Woffset))
{xon = 0;xPos = (width - Woffset); }
}
function start()
{
img1.visibility = "visible";
interval = setInterval('changePos()', delay);
}
function pause_resume()
{
if(pause)
{
clearInterval(interval);
pause = false;}
else
{
interval = setInterval('changePos()',delay);
pause = true;
}
}
start();
