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 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();
}
});
}
怎样用javascript实现带关闭窗口的浮动广告
首先浮动的窗口就是一个层，在这个层上放置一个小的层，代表关闭按钮，可以使用背景图片，或者img，用小层装，是为来方便固定位置，在这个小层中可以写js代码，当鼠标点击是获得大层，修改大层的隐藏属性，这样就实现来，整个层的关闭
在网页中插入浮动窗口，js代码或css代码（易看易懂）
给你一段代码，创建了一个大小100*100的浮动窗口，贴着窗口的右边。
css代码：
style type="text/css"
#my_dialog {
position: fixed; /*固定定位*/
right: 0;
top: 50%; /*贴着右边，垂直位置50%*/
height: 100px;
width: 100px; /*尺寸 100 x 100*/
transform: translate(0, -50%); /*通过位移，保证浮动窗口的垂直居中*/
box-shadow: 0 0 3px 1px rgba(180, 180, 180, 0.5);
background-color: white; /*加些背景色和阴影，以便区分*/
}
/style
html代码：
div id="my_dialog"
!--窗口内容--
/div
javascript如何实现弹出浮动窗口
