超酷右下角浮出窗口《修订版》--关闭时缓慢下降并消失

           在网络上找的类似QQ的右下角浮出窗口 JS代码，感觉关闭的时候很不舒服，自己花了近一天修改了其中的部分代码，添加了缓慢下降的功能，现在看着更酷了哦。

        不敢独享，贴出来大家一起研究。

          

看到右下角的提示了吗？如果没有看到，<button onclick=getMsg();>弹出</button>
<script language="JavaScript">...
//window.onload = getMsg;
//window.onresize = resizeDiv;
//window.onerror = function(){}
//短信提示使用(asilas添加)
var divTop,divLeft,divWidth,divHeight,docHeight,docWidth,objTimer,i = 0;
