相信很多使用IE10的童鞋们已经发现了这个问题,以下是本人在IE10标准模式下发生的问题,声明:IE10不只有一个版本。
1.服务器控件属性丢失,在aspx页面定义的TextBox:
<asp:TextBox ID="txt" runat="server" Width="200" />
在IE10标准模式下浏览发现宽度不对,遂打开源代码发现成这样了:
<input name="txt" type="text" id="txt" /> width属性没了
2.偶尔发现页面报错__doPostBack找不到
目前就发现以上两点,第一反应就是兼容性问题,查了一些资料,果然是IE10的bug,不禁对微软的产品不满,新的浏览器尽然连自己的服务器控件都存在兼容性问题。
一般用户只需要设置浏览器在兼容模式下运行就可以解决了,但是开发人员怎么去解决这个问题呢?
VS项目里加App_Browsers文件夹,加ie.browser文件,文件内容帖下面的内容:
<browsers> <!-- Mozilla/5.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4325) --> <browser id="IE6Plus" parentID="IE"> <identification> <capability name="majorversion" match="^[6-9]|\d{2,}$" /> </identification> <capabilities> <capability name="ecmascriptversion" value="3.0" /> <capability name="jscriptversion" value="5.6" /> <capability name="javascript" value="true" /> <capability name="javascriptversion" value="1.5" /> <capability name="msdomversion" value="${majorversion}.${minorversion}" /> <capability name="w3cdomversion" value="1.0" /> <capability name="ExchangeOmaSupported" value="true" /> <capability name="activexcontrols" value="true" /> <capability name="backgroundsounds" value="true" /> <capability name="cookies" value="true" /> <capability name="frames" value="true" /> <capability name="javaapplets" value="true" /> <capability name="supportsCallback" value="true" /> <capability name="supportsFileUpload" value="true" /> <capability name="supportsMultilineTextBoxDisplay" value="true" /> <capability name="supportsMaintainScrollPositionOnPostback" value="true" /> <capability name="supportsVCard" value="true" /> <capability name="supportsXmlHttp" value="true" /> <capability name="tables" value="true" /> <capability name="supportsAccessKeyAttribute" value="true" /> <capability name="tagwriter" value="System.Web.UI.HtmlTextWriter" /> <capability name="vbscript" value="true" /> </capabilities> </browser> <!-- Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0;) --> <browser id="IE6to9" parentID="IE6Plus"> <identification> <capability name="majorversion" match="^[6-9]$" /> </identification> </browser> <!-- Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0;) --> <browser id="IE7" parentID="IE6to9"> <identification> <capability name="majorversion" match="^7$" /> </identification> <capabilities> <capability name="jscriptversion" value="5.7" /> </capabilities> </browser> <!-- Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729) --> <browser id="IE8" parentID="IE6to9"> <identification> <capability name="majorversion" match="^8$" /> </identification> <capabilities> <capability name="jscriptversion" value="6.0" /> </capabilities> </browser> <!-- Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729) --> <browser id="IE9" parentID="IE6to9"> <identification> <capability name="majorversion" match="^9$" /> </identification> <capabilities> <capability name="jscriptversion" value="6.0" /> </capabilities> </browser> <!-- Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0) --> <browser id="IE10Plus" parentID="IE6Plus"> <identification> <capability name="majorversion" match="\d{2,}" /> </identification> <capabilities> <capability name="jscriptversion" value="6.0" /> </capabilities> </browser> <gateway id="IEbeta" parentID="IE"> <identification> <capability name="letters" match="^([bB]|ab)" /> </identification> <capture> </capture> <capabilities> <capability name="beta" value="true" /> </capabilities> </gateway> </browsers>
这是一种基于站点的修复方式,参考微软官方资料:
.NET 4 浏览器更新 NuGet 包 - http://nuget.org/List/Packages/App_BrowsersUpdate
.NET 2.0 浏览器更新 NuGet 包 - http://nuget.org/List/Packages/App_BrowsersUpdate.net20
还有一种是打补丁,能解决服务器上所有站点的兼容性问题
.NET 4 - http://support.microsoft.com/kb/2600088
.NET 2.0 - http://support.microsoft.com/kb/2600100
另外博主在项目里用了大量的devexpress服务器控件,苦不堪言,虽然按照以上方式进行修复,VS自带的控件倒是没出现问题,但是dev控件却一大堆错误,最终还是没有修复,只能让用户使用兼容性模式。
只希望微软发布下一版本浏览器时能修复这个问题
