简单，漂亮，动画效果，用户体验好！ 
这个效果是在页面头部出现的，出现一下会自动隐藏，上面有x那个提示就要手动关闭一下，其他的都是自动隐藏的！
温馨提示：基于jquery 1.6.2 版本！
复制代码 代码如下:
<div id="message-dock">
<div id="message-sleeve" class="group">
<p><span class="sprite message-icon"></span><span id="message-text"></span><a class="dismiss"></a></p>
</div>
</div>
调用方式：
复制代码 代码如下:
<script type="text/javascript" src="sysmsg.js"></script>
<script type="text/javascript">
ZENG.SysMsg.show('邮件格式错误！', "error");
ZENG.SysMsg.show('请重新来过！', "alert");
ZENG.SysMsg.show('保存成功！');</script>
jquery版：

if (!window.ZENG) var ZENG = {};
ZENG.add = function(d, f) {

if ($.isFunction(f.init)) {
