[转贴]现在在做一个WEB的站内消息系统，从工具栏位置弹出一徐徐上升的窗口

现在在做一个WEB的站内消息系统，
想在用户登陆时，
如果有未读短消息
则从工具栏位置弹出一徐徐上升的窗口
显示提醒信息！

<script language="JavaScript" type="text/javascript">
var divTop,divLeft,divWidth,divHeight,docHeight,docWidth,objTimer,i = 0;
function getMsg()
{
try{
window.open("Top.aspx","TopMusic");
divTop = parseInt(document.getElementById("eMeng").style.top,10)
divLeft = parseInt(document.getElementById("eMeng").style.left,10)
divHeight = parseInt(document.getElementById("eMeng").offsetHeight,10)
divWidth = parseInt(document.getElementById("eMeng").offsetWidth,10)
docWidth = document.body.clientWidth;
docHeight = document.body.clientHeight;
document.getElementById("eMeng").style.top = parseInt(document.body.scrollTop,10) + docHeight + 10;// divHeight
document.getElementById("eMeng").style.left = parseInt(document.body.scrollLeft,10) + docWidth - divWidth
document.getElementById("eMeng").style.visibility="visible"
objTimer = window.setInterval("moveDiv()",10)
}
catch(e){}
}

function resizeDiv()
{
i+=1
if(i>1288) closeDiv()
try{
divHeight = parseInt(document.getElementById("eMeng").offsetHeight,10)

document.getElementById("eMeng").style.left = docWidth - divWidth + parseInt(document.body.scrollLeft,10)
}
catch(e){}
}

function moveDiv()
{
try
{

{
window.clearInterval(objTimer)
objTimer = window.setInterval("resizeDiv()",1)
}
divTop = parseInt(document.getElementById("eMeng").style.top,10)
document.getElementById("eMeng").style.top = divTop - 1
}
catch(e){}
}
function closeDiv()
{
document.getElementById('eMeng').style.visibility='hidden';
if(objTimer) window.clearInterval(objTimer)
}
window.onload = getMsg;
window.onresize = resizeDiv;
window.onerror = function(){}
