    调用代码:

     <mce:script language="javascript" type="text/javascript"><!-- var msg1 = new msnMessage("aa",200,120,"短消息提示:","您有1封消息","今天请我吃饭哈","11.htm"); msg1.rect(null,null,null,screen.height-50); msg1.speed = 10; msg1.step = 5; //alert(msg1.top); msg1.show(); //同时两个有闪烁,只能用层代替了,不过层不跨框架 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(); // --></mce:script>   

    注意:如果是在asp.net中,js文件中包含的字符通过innerHTML输出后会显示乱码,作如下改动:

    1.Web.config中加入 <system.web> <globalization requestEncoding="utf-8" responseEncoding="utf-8" /> </system.web> 2.Aspx页面文件中加入 <META http-equiv="content-type" content="text/html; charset=gb2312"> 3.在页面加载事件中加入下句: Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");

    原因是如果js写在asp.net中,一般是不会出现乱码的问题。因为他们具有相同的编码。如果需要引用外部的javascript代码就会有乱码的风险了。一般情况下Asp.net和Javascript的页面编码不是GB2312就是Utf-8 ,如果两者的编码不一致就会产生乱码。解决方法就是想两者的编码进行统一。由于一般情况下Asp.net接受发送请求的编码是Utf-8的,javascript编码默认是Gb2312,故容易出现问题。
