把上面的代码另存为一个*.JS文件，然后在想实现此效果的页面用 SCRIPT src="*.js"/SCRIPT
调用即可，*代表你另存的文件名！注意修改广告图片地址和连接地址！相应的参数可以根据页面自行调整。
这个是左右下角的浮动
浮动窗口的代码 （html/js）
第一种方法:
Html代码
html
head
title浮动窗口/title
link type="text/css" rel="stylesheet" href="css/overflow.css" /
script type="text/javascript" src="js/jquery.js"/script
script type="text/javascript" src="js/overflow.js"/script
script type="text/javascript"
$(document).ready(function(){
var b = $("#b");
var overFlow = $("#over");
b.click(function(){
overFlow.fadeIn();
$("#mask").css("background","#111");
$("#mask").css("opacity","0.8");
})
$("#close").click(function(){
overFlow.fadeOut();
$("#mask").css("background","#fff");
$("#mask").css("opacity","1");
});
drag($("#over"),$("#title"));
}) ;
/script
/head
body
div id="over"
div id="title"span id="t"这只是一个演示标题/spanspan id="close"[ x ]/span/div
div id="content"
When a container object, such as a div, has mouse capture, events originating on objects within that container are fired by the div, unless the bContainerCapture parameter of the setCapture method is set to false. Passing the value false causes the container to no longer capture all document events. Instead, objects within that container still fire events, and those events also bubble as expected.br/

/div
/div
div id="mask" a id="b" href="#"click/a/div
/body
/html
Js代码
function drag(overFlow,title){
title.onmousedown = function(evt){
var doc = document;
var evt = evt || window.event;
var x = evt.offsetX?evt.offsetX:evt.layerX;
var y = evt.offsetY?evt.offsetY:evt.layerY;
if(overFlow.setCapture){
overFlow.setCapture();
}else if(window.captureEvents){
window.captureEvents(Event.MOUSEMOVE|Event.MOUSEUP);
}
doc.onmousemove = function(evt){
evt = evt || window.event;
var xPosition = evt.pageX || evt.clientX;
var yPosition = evt.pageY || evt.clientY;
var newX = xPosition - x;
var newY = yPosition - y;
overFlow.style.left = newX;
overFlow.style.top = newY;
};
doc.onmouseup = function(){
if(overFlow.releaseCapture){
overFlow.releaseCapture();
}else if(window.captureEvents){
window.captureEvents(Event.MOUSEMOVE|Event.MOUSEUP);
}
doc.onmousemove=null;
doc.onmouseup=null;
};
};
}
css代码
#over{
position: absolute;
left: 300px;
top: 200px;
border: 1px solid black;
display: none;
background: #cccccc;
cursor: default;
width: 300px;
z-index: 10;
opacity: 1;
}
#title{
border: 1px solid #1840C4;
background: #95B4DC;
padding: 2px;
font-size:12px;
cursor: default;
}
#close{
cursor: pointer;
margin-right: 1px;
overflow: hidden;
}
#content{
border: 1px solid #C2D560;
background: #EFF4D7;
}
#t{
margin-right:145px;
}
#mask{
z-index: 1;
background: #fff;
width: 1024px;
height: 800px;
}
#b{
position: absolute;
left: 200px;
top: 100px;
}
body{
padding: 0px;
margin: 0px;
}
#over{
background: transparent;
}
第二种方法:
消息框遮罩层:iframe id="show_upload_iframe" frameborder=0 scrolling="no" style="display:none; position:absolute;"/iframediv id="show_upload"nothing.../div'
页面加载loading中:div id="body_loading" onClick="loaded();"img src="__PUBLIC__/images/body_load.gif"/div
关闭浮动窗口:a href="javascript:hideupload()"关闭窗口建议用小图片/a
打开浮动窗口:a href="javascript:showupload('admin.php')"打开浮动/a
// 消息框loading
function loading(){
var o = $('#body_loading');
o.css("left",(($(document).width())/2-(parseInt(o.width())/2))+"px");
o.css("top",(($(document).height()+$(document).scrollTop())/2-(parseInt(o.height())/2))+"px");
o.fadeIn("fast");
}
// 消息框消失
function loaded(){
var o = $('#body_loading');
o.fadeOut("fast");
}
// 隐藏浮动窗口
function hideupload(){
$('#show_upload').hide();
$('#show_upload_iframe').hide();
}
// 弹出浮动窗口
function showupload(ajaxurl){
loading();
var o=$('#show_upload');
var f=$('#show_upload_iframe');
var top = 200;
$.ajax({
url: ajaxurl,
//cache: false,
success: function(res){
loaded();
o.html(res);
o.css("left",(($(document).width())/2-(parseInt(o.width())/2))+"px");
if($(document).scrollTop()200){
top = ($(document).height()+$(document).scrollTop())/2-(parseInt(o.height())/2);
}
o.css("top",top+"px");
f.css({'width':o.width(),'height':o.height(),'left':o.css('left'),'top':o.css('top')});
f.show();
o.show();
}
});
}
求高手指点,网页超过某指定的高度high后,加载运行某JS浮动广告代码,在左侧位置浮动显示的方法?
用jQuery (或者任意的js library,比如prototype. 当然你不想用也行)
var documentHeight = $(document).height();
$('div id="some-id2"!-- your code here --/div').insertAfter('#some-id');
如果对jQuery不熟悉，参考jQueryI官方网上的API
