Html代碼
代碼如下:
<html>
<head>
<title>浮動窗口</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">這只是一個演示標題</span><span 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代碼
代碼如下:
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代碼
代碼如下:
#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;
}
第二種方法:
消息框遮罩層:<iframe id="show_upload_iframe" frameborder=0 scrolling="no" style="display:none; position:absolute;"></iframe><div id="show_upload">nothing...</div>'
頁面加載loading中:<div id="body_loading" onClick="loaded();"><img src="__PUBLIC__/images/body_load.gif"></div>
關閉浮動窗口:<a href="javascript:hideupload()">關閉窗口建議用小圖片</a>
打開浮動窗口:<a href="javascript:showupload('admin.php')">打開浮動</a>
代碼如下:
// 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");
}
// 隱藏浮動窗口
function hideupload(){
$('#show_upload').hide();
$('#show_upload_iframe').hide();
}
// 彈出浮動窗口
function showupload(ajaxurl){
loading();
var o=$('#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();
}
});
