实现功能：
1.修改标题样式。把jquery ui的标题样式放上去。支持换肤。
2.修改按钮样式，换成jqueryui的button按钮样式。
3.将模式化窗口的背景换成了jqueryui的模式化背景。
代码：
//首先要引入jquery，以及ui的包和皮肤的样式如：
(function($) {
$.alerts = {
// These properties can be read/written by accessing $.alerts.propertyName from your scripts at any time
verticalOffset: -75, // vertical offset of the dialog from center screen, in pixels
horizontalOffset: 0, // horizontal offset of the dialog from center screen, in pixels/
repositionOnResize: true, // re-centers the dialog on window resize
overlayOpacity: .01, // transparency level of overlay
overlayColor: '#FFF', // base color of overlay
draggable: true, // make the dialogs draggable (requires UI Draggables plugin)
okButton: ' 确认 ', // text for the OK button
cancelButton: ' 取消 ', // text for the Cancel button
dialogClass: null, // if specified, this class will be applied to all dialogs
// Public methods
