簡單，漂亮，動畫效果，用戶體驗好！ 
這個效果是在頁面頭部出現的，出現一下會自動隱藏，上面有x那個提示就要手動關閉一下，其他的都是自動隱藏的！
溫馨提示：基於jquery 1.6.2 版本！
代碼如下:
<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>
調用方式：
代碼如下:
<script type="text/javascript" src="sysmsg.js"></script>
<script type="text/javascript">
ZENG.SysMsg.show('郵件格式錯誤！', "error");
ZENG.SysMsg.show('請重新來過！', "alert");
ZENG.SysMsg.show('保存成功！');</script>
jquery版：
代碼如下:
/*!
* jQuery JavaScript SysMsg v1.0
* http://zengxiangzhan.cnblogs.com/
* jQuery.sysmsg.js
* Copyright 2011, 曾祥展
* Date: 2011-8-1 20:00 2011 -2210
*/
if (!window.ZENG) var ZENG = {};
ZENG.add = function(d, f) {
var j;
if ($.isFunction(f.init)) {
j = f.init;
delete f.init;
$.extend(true, j.prototype, f);
this[d] = j
} else this[d] = f
};
ZENG.add("SysMsg", function() {
function d(u, D, v) {
D || (D = "success");
v = v || D == "error";
if (o) {
h.push(function() {
d(u, D)
});
f()
} else {
m.html(u);
i.removeClass().addClass(D).show().animate({
top: 0
}, 200, function() {
v || j()
});
o = 1
}
}
function f() {
i.animate({
top: "-50px"
}, 200, function() {
i.hide();
o = 0;
h.length && h.shift()()
})
}
function j() {
setTimeout(function() {
f()
}, 2E3)
}
var o, h = [],
i = $("#message-dock"),
m = i.find("#message-text");
$(".dismiss", "#message-dock").live("click", function(u) {
f();
u.preventDefault()
});
return {
show: d
}
}());
