<script type="text/javascript">
function showp(){

<p style="padding-top: 20px;">

附加一个好看的样式
代码如下:
<html>
<head><title></title>
<style>
.mesWindowTop {
font-size: 12px;
font-weight: bold;
text-align: left;
}
.mesWindowContent {
font-size: 12px;
}
.mesWindow {
background: none repeat scroll 0 0 #FFFFFF;
border: 1px solid #666666;
}
</style>
</head>
<body>
<p id="mesWindow" class="mesWindow" style="top: 180px; position: absolute; width: 600px; margin-left: -300px; left: 50%; z-index: 9999;"><p class="mesWindowTop"><table width="100%" height="100%"><tbody><tr><td>窗口标题</td><td style="width:1px;"><input type="button" value="关闭" class="close" title="关闭窗口" onclick="closeWindow();"></td></tr></tbody></table></p><p id="mesWindowContent" class="mesWindowContent"><p style="padding:20px 0 20px 0;text-align:center">消息正文</p></p><p class="mesWindowBottom"></p></p>
</body>
