+## 更新记录
+
+### 5.0.4

+2.	取消鸡肋的 esc 参数
+3.	给关闭按钮增加 title，以便让读屏器正常发音(感谢 @杨永全 老师的建议)
+4.	解决 iframe 页面中上一版报错问题(ie8,9)#26 #21
+
+### 5.0.3
+
+1.	**支持信息无障碍（ARIA）**

+3.	对话框关闭后焦点将恢复至原来的元素
+
+### 5.0.2
+
+1.	修复居中可能导致左边框显示不出的问题
+2.	取消点击遮罩对话框恢复居中的特性
+
+### 5.0.1
+
+1. 修正重复调用 close 方法出现的错误
+2. 修正设定了follow后再使用content()方法导致其居中的问题
+
+### 5.0.0
+
+[重新回到当初的理念：简单、优雅]
+
+1.  follow 不再支持 String 类型
+2.  button 参数只支持 Array 类型
+3.  button name 成员改成 value
+4.  button 增加 id 成员
+5.  okVal 参数更名为 okValue, 默认值由 '确定' 改为 'ok'
+6.  cancelVal 参数更名为 cancelValue, 默认值由 '取消' 改为 'cancel'
+6.  close 参数更名为 beforeunload
+7.  init 参数更名为 initialize
+8.  title 参数默认值由 '消息' 改为 'message'
+9.  time 参数与方法参数单位由秒改为毫秒
+10. hide 参数方法更名为 hidden
+11. 内部为皮肤增加动态样式 d-state-visible 类
+12. 给遮罩增添样式 d-mask 类
+13. background 参数被取消, 由 CSS 文件定义
+14. opacity 参数被取消, 由 CSS 文件定义
+15. **取消拖动特性，改由插件支持**

+25. content 方法不支持空参数
+26. button 方法的参数不支持数组类型
+27. 判断 DOCTYPE, 对 xhtml1.0 以下的页面报告错误
+28. 修复 IE8 动态等新内容时没有撑开对话框高度，特意为 ie8 取消 .d-content { display:inline-block }
+29. show 参数与方法更名为 visible
+
+### 4.0.0
+
+[严谨的跨浏览器支持、对框架应用提供强大的api支持]
+
+源码：<http://code.google.com/p/artdialog/>
+
+1.	修复刷新框架后脚本报错的问题
+2.	修复异步加载 artDialog.js 导致锁屏无法使用的问题
+3.	双击遮罩不再直接关闭，而是等同于关闭按钮与取消按钮
+4.	修复 IE6 在特殊情况下可能因为 fixed 定位出现 body 背景图片异常
+5.	修复部分皮肤在 firefox7.0 版下，标题栏出现省略号的问题
+6.	修复 v4.0.5 之后版本在浏览器窗口调节的时候可能出现对话框变形问题
+7.	top 参数黄金比例不再采用单独的关键字，可使用 '38.2%' 表示
+8.	**新增 content 扩展方法写入消息后，让对话框以自身为中心放大的特性**
+9.	增加高亮按钮的样式：确定按钮默认高亮（自定义按钮可使用focus参数高亮）
+10.	解决IE浏览器按钮字体模糊问题
+11.	jQuery版本最低兼容jQuery 1.3.2
+12.	新增artDialog 基本版本；它只拥有核心功能，文件只有常规版本的一半大小，可被客户端快速载入
+13.	精简内嵌事件系统，进一步减少体积(压缩版比上一版本少近了3kb)
+14.	iframeTools: open方法默认不再强制锁屏
+15.	增强icon参数自由度，不再依赖对话框样式文件定义。可存入任意图标到“skins/icons/”并使用它们
+16.	iframeTools: 拖拽操作增加透明遮罩，防止鼠标指针落入框架而导致监听失败，提高拖拽流畅性
+17.	iframeTools: 对open方法增加一个私有的iframe扩展方法，用来引用其创建的iframe对象
+18.	新增点击内容部分也可以如点击标题一样置顶对话框的特性
+19.	iframeTools： 增加父页面刷新与关闭后子对话框也将关闭的特性。（由于iframe注销后其产生的对象会被大多数浏览器在内存中移除，增加此特性可以有效的解决对话框报错）
+20.	**DOM底层api兼容jQuery api，同步发行jQuery版本**
+21.	**消息内容支持传入DOM元素**
+22.	增加title标题接口
+23.	增加button自定义按钮接口
+24.	增加lock与unlock接口
+25.	新增data方法用来在iframe之间共享数据
+26.	重定义zIndex配置参数
+27.	重新支持调节对话框大小
+28.	支持用第三方框架加载自身
+29.	**配置参数全部为可选，如果没有content，它将出现loading动画**
+30.	left与top关键字用百分比代替，同时增加width与height传递百分比参数
+31.	更好的支持iframe
+32.	修复若干BUG
+
+### 3.0.0
+
+[初次支持框架]
+
+1.	修复iPad或iPhone下使用锁屏焦点自动弹出的问题
+2.	修复移动设备使用手势缩放页面带来的漂移问题
+3.	修复fixed在移动设备中支持不完整的问题
+4.	修复window.top是框架集(frameset)页面可能会带来无限循环递归的问题
+5.	增加art.dialog.get()方法获取指定ID对话框API
+6.	修复框架集（frameset）页面不能植入artDialog而产生js报错的问题，并增加了其支持
+7.	公开默认配置的读写
+8.	重写IE6 fixed实现
+
+### 2.0.0
+
+[进一步封装]
+
+1.	**支持多对话框共存**
+2.	支持返回扩展方法关闭对话框
+3.	解决v1已知的一些BUG
+
+### 1.0.0
+
+[诞生]
+
+1.	**高度与宽度支持原生自适应内容，自适应文本对齐**
+2.	支持拖动、Esc关闭对话框、坐标定位
+3.	**支持自适应位置**
+4.	**支持IE6无抖动静止定位**
