解决Easyui1.3.3 IE8兼容性问题

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：http://www.jeasyui.com/。

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)

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:   jquery官方下载1.10.2最新版本

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：

                if (cookie.substring(0, name.length + 1) == (name + '=')) {
                    cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                    break;
                }
            }
        }
        return cookieValue;
    }
};

注：页面显示脚本报错主要的原因是jquery存在问题，这里面使用到了两个jquery版本。
