jQuery之浮动窗口实现代码(两种方法)_建站学-个人建站指南,网页制作,网站设计,网站制作教程

今天公司要求实现浮动窗口效果，自己看了不少资料终于实现此效果。用jQ实现浮动窗口功能,弹出窗口时背景变暗.

第一种方法:
预览:

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</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>
<div id="mask"> <a id="b" href="#">click</a></div>
</body>
</html>

Js代码

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;"></iframe><div 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();
}
});
}
