这是别人写的代码，很好用，效果很好。作为一个学习教材也很好。
为了方便使用，我把上述js放到一个js文件中，以后使用的话，引入它就可以了。

MSG1.speed = 5;
MSG1.step = 1;
MSG1.show();

调用页面：
pop.html
<script type="text/javascript" src="poplittle.js"></script>
<input type="button" value="右下角弹出" onclick="tanchu()">
<SCRIPT language=JavaScript>
function tanchu(){
var MSG1 = new CLASS_MSN_MESSAGE("msg",200,120,"xxxxx在线服务!","欢迎您访问我们的网站，有什么需要我们帮忙的么？","提示:您有(1)条信息，请查收!");
MSG1.rect(null,null,null,screen.height-50);
MSG1.speed = 5;
MSG1.step = 1;
MSG1.show();
}
</SCRIPT>
这样使用起来就很方便，我们只要传入显示的内容就可以了。
