很酷的模仿msn消息提示的效果。打开页面之后你会发现右下角有消息框弹出，跟msn的消息框很相似！
[code]





<script>
var opopup = window.createpopup();
var poptop=50;
function popmsg(msgstr){
var winstr="";
winstr+="

欢迎光临……

"; winstr+=" "+msgstr+"

";
opopup.document.body.innerhtml = winstr;
popshow();
}
function popshow(){
window.status=poptop;
if(poptop>1719){
cleartimeout(mytime);
opopup.hide();
return;
}else if(poptop>1520 && poptop<1719){
opopup.show(screen.width-250,screen.height,241,1720-poptop);
}else if(poptop>1500 && poptop<1520){
opopup.show(screen.width-250,screen.height+(poptop-1719),241,172);
}else if(poptop<180){
opopup.show(screen.width-250,screen.height,241,poptop);
}else if(poptop<220){
opopup.show(screen.width-250,screen.height-poptop,241,172);
}
poptop+=10;
var mytime=settimeout("popshow();",62);
}
popmsg(" 源码爱好者提供有质量源码下载，每款源码都经过精心测试，请放心使用！");
