事先声明：项目在Firefox和Chrome上完美运行，在MSIE9、MSIE10上基本没问题，但是放在MSIE8上面运行问题就出来了。登录系统后，系统页面跳动，导致系统无法使用；我使用的是Easyui1.3.3。经过网上查找N久，最终解决MSIE8的兼容性问题（客户是国企，他们都是使用的MSIE8没办法必须解决问题）。
Jquery EasyUI 怎么使用这里就不做介绍了，官网地址：。
1、常见错误提示如下
详细内容如下：
用户代理: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.2; Trident/4.0; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; InfoPath.2; MS-RTC LM 8; .NET4.0C; .NET4.0E)
时间戳: Fri, 22 Nov 2013 05:46:30 UTC消息: 对象不支持此属性或方法行: 4字符: 6102代码: 0URI: http://localhost/wtms/jquery.min.js消息: 'jQuery' 未定义行: 12字符: 1代码: 0URI: http://localhost/wtms/jquery.easyui.min.js消息: 缺少对象行: 19字符: 1代码: 0URI: http://localhost/wtms/demo/dialog/toolbarbuttons.html
2、确认使用正确的Jquery版本。
Easyui下有个jquery.min.js，这个不能使用，需替换为jquery-1.10.2.min.js文件。
jquery-1.10.2.min.js:
3、EasyUI的主题切换cookie.
changeTheme = function(themeName) { var $easyuiTheme = $('#easyuiTheme'); var url = $easyuiTheme.attr('href'); var href = url.substring(0, url.indexOf('themes')) + 'themes/' + themeName + '/easyui.css'; $easyuiTheme.attr('href', href); var $iframe = $('iframe'); if ($iframe.length > 0) { for ( var i = 0; i < $iframe.length; i++) { var ifr = $iframe[i]; $(ifr).contents().find('#easyuiTheme').attr('href', href); } } $.cookie('easyuiThemeName', themeName, { expires : 7 }); //location.reload();//注释掉是因为页面在MSIE8中跳动，无法正常显示}; 此文件需要jquery-1.5.2.min.js支持，另外还需要：jquery.coner.js和jquery.cookie.js支持。
jquery.cookie.js的代码如下：
