用javascript作消息提示框（类似于QQ用户上线的消息提示）

在开发项目的时候，需要在有用户消息的时候提醒用户，刚好自己的QQ好友上线，QQ自动弹出一个消息提示，觉得不错。所以用javascript利用popup作了一个类似的功能。
<html>
<head>
<title>HTMLPage1</title>
<meta name="vs_defaultClientScript" content="javascript">
<meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5">
<meta name="GENERATOR" content="Microsoft Visual Studio .NET 7.1">
<meta name="ProgId" content="VisualStudio.HTML">
<meta name="Originator" content="Microsoft Visual Studio .NET 7.1">
</head>

<script language =javascript>
   var titlePopup
   var len;

   function InitMsgBox()
   { len = 0;
    titlePopup=window.createPopup();
    var titlePopupBody = titlePopup.document.body;
    titlePopupBody.style.border ="solid black 1px";
    var titleContent = "";
    titleContent = titleContent + "<table cellPadding='5' bgcolor='#65c1ff' width='100%' height='100%' border=0 cellspacing=0 cellpadding=0>";
    titleContent = titleContent + "<tr><td align=center><font size = 2>消息提醒</font></td></tr>";
    titleContent = titleContent + "<tr><td><font size = 2>内容</td></font></tr>";
    titleContent = titleContent + "<tr><td><font size = 2>内容</td></font></tr>";
    titleContent = titleContent + "<tr><td><font size = 2>日期</td></font></tr>";
    titleContent = titleContent + "</table>";
    titlePopupBody.innerHTML = titleContent;

    ShowMsgBox();
   }

   function MsgBox()
   {
    len += 4;
    if (len > 110)
    {
     window.clearInterval(tID);
    }
    else
    {//170固定了消息提示框的宽度
     titlePopup.show(document.body.clientWidth - 170, document.body.clientHeight - len, 170, len, top.document.body);
    }
   }

   var tID
   function ShowMsgBox()
   {
    tID = window.setInterval("MsgBox()",15);
   }
</script>

<body MS_POSITIONING="GridLayout">
<INPUT onclick="InitMsgBox()" id="Button1" style="Z-INDEX: 101; LEFT: 296px; POSITION: absolute; TOP: 344px" type="button"
   value="Button" name="Button1">
</body>
</html>
