jQuery之浮动窗口实现代码(两种方法)

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;”></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’)});
