IE10、IE11使用 __doPostBack 出现未定义问题

时间:2021-02-20 01:51:38

  在公司的老项目中分页控件使用了 __doPostBack 方式,在IE兼容模式下正常,在IE10、IE11中 __doPostBack 出现未定义问题。

  百度查阅资料得知,这是微软NET环境下的一个BUG,官方已经发布了新的补丁包,可直接通过下载最新Framwork补丁得到修改。

  除此办法以外,还可以在项目中直接修改,方法如下:

  1、项目根目录下,建App_Browsers文件夹

  2、在文件夹中新建文件ie.browser文件,文件内容粘贴如下内容:

<browsers>
<browser id="IE11" parentID="Mozilla">
<identification>
<userAgent match="Trident\/7.0; rv:(?'version'(?'major'\d+)(\.(?'minor'\d+)?)(?'letters'\w*))(?'extra'[^)]*)" />
<userAgent nonMatch="IEMobile" />
</identification>
<capture>
<userAgent match="Trident/(?'layoutVersion'\d+)" />
</capture>
<capabilities>
<capability name="browser" value="IE" />
<capability name="layoutEngine" value="Trident" />
<capability name="layoutEngineVersion" value="${layoutVersion}" />
<capability name="extra" value="${extra}" />
<capability name="isColor" value="true" />
<capability name="letters" value="${letters}" />
<capability name="majorversion" value="${major}" />
<capability name="minorversion" value="${minor}" />
<capability name="screenBitDepth" value="8" />
<capability name="type" value="IE${major}" />
<capability name="version" value="${version}" />
</capabilities>
</browser>
<!-- Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11,0) like Gecko -->
<browser id="IE110" parentID="IE11">
<identification>
<capability name="majorversion" match="11" />
</identification> <capabilities>
<capability name="ecmascriptversion" value="3.0" />
<capability name="jscriptversion" value="5.6" />
<capability name="javascript" value="true" />
<capability name="javascriptversion" value="1.5" />
<capability name="msdomversion" value="${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>
</browsers>

  3、重启IIS尝试是否修正错误,如未修正,把上述代码粘贴到%WinDir%\Microsoft.NET\Framework64\v4.0.30319\CONFIG\Browsers文件夹

再次尝试。

  4、如果还不行,请安装NET插件:http://www.microsoft.com/zh-cn/download/details.aspx?id=28936
