調用代碼：
?
Code<script?language="javascript"?type="text/javascript">
var?msg1?=?new?msnMessage("aa",200,120,"短消息提示：","您有1封消息","今天請我吃飯哈","11.htm");??
msg1.rect(null,null,null,screen.height-50);
msg1.speed?=?10;
msg1.step?=?5;?
//alert(msg1.top);?
msg1.show();??
//同時兩個有閃爍，只能用層代替了，不過層不跨框架?
var?msg2?=?new?msnMessage("aa",200,120,"短消息提示：","您有2封消息","好的啊","22.htm");??
msg2.rect(100,null,null,screen.height);?
msg2.show();??
</script>
?
注意：如果是在asp.net中，js文件中包含的字符通過innerHTML輸出后會顯示亂碼，作如下改動：
1.Web.config中加入 <system.web> <globalization requestEncoding="utf-8" responseEncoding="utf-8" /> </system.web>
2.Aspx頁面文件中加入
<META http-equiv="content-type" content="text/html; charset=gb2312">
3.在頁面加載事件中加入下句：
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
原因是如果js寫在asp.net中，一般是不會出現亂碼的問題。因為他們具有相同的編碼。如果需要引用外部的javascript代碼就會有亂碼的風險了。一般情況下Asp.net和Javascript的頁面編碼不是GB2312就是Utf-8 ，如果兩者的編碼不一致就會產生亂碼。解決方法就是想兩者的編碼進行統一。由于一般情況下Asp.net接受發送請求的編碼是Utf-8的，javascript編碼默認是Gb2312，故容易出現問題。
