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： <script src="https://www.jb51.net/js/ui/jquery-1.11.0.min.js"></script> <script src="https://www.jb51.net/js/ui/jquery-migrate-1.1.0.min.js"></script> <script src="https://www.jb51.net/js/ui/minified/jquery.ui.core.min.js"></script> <script src="https://www.jb51.net/js/ui/minified/jquery.ui.widget.min.js"></script> <script src="https://www.jb51.net/js/ui/minified/jquery.ui.mouse.min.js"></script> <script src="https://www.jb51.net/js/ui/minified/jquery.ui.button.min.js"></script> <script src="https://www.jb51.net/js/ui/minified/jquery.ui.draggable.min.js"></script> <link type="text/css" href="https://www.jb51.net/js/ui/themes/humanity/jquery-ui.css"></link> (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 alert: function(message, title, callback) { if( title == null ) title = 'Alert'; $.alerts._show(title, message, null, 'alert', function(result) { if( callback ) callback(result); }); }, confirm: function(message, title, callback) { if( title == null ) title = 'Confirm'; $.alerts._show(title, message, null, 'confirm', function(result) { if( callback ) callback(result); }); }, prompt: function(message, value, title, callback) { if( title == null ) title = 'Prompt'; $.alerts._show(title, message, value, 'prompt', function(result) { if( callback ) callback(result); }); }, // Private methods _show: function(title, msg, value, type, callback) { $.alerts._hide(); $.alerts._overlay('show'); $("BODY").append( '<div>' + '<h2></h2>' + '<div>' + '<div></div>' + '</div>' + '</div>'); if( $.alerts.dialogClass ) $("#popup_container").addClass($.alerts.dialogClass); // IE6 Fix //var pos = ($.browser.msie && parseInt($.browser.version) <= 6 ) ?
