Html代码

这只是一个演示标题[ x ]

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.

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{

left: 300px;
top: 200px;
border: 1px solid black;

第二种方法:
消息框遮罩层:

　　页面加载loading中:

　　关闭浮动窗口:关闭窗口建议用小图片

　　打开浮动窗口:打开浮动

// 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();
}
});
