IE11出现“__doPostBack未定义”的解决办法。

时间:2024-07-10 14:03:26

方法一:浏览器设置成兼容模式,这个是超级掩耳盗铃方法,你就没想过其他人也会出这个问题。

方法二、安装服务器版的.Net40的补丁。http://download.****.net/detail/5653325/6642051

方法三、点击VS的工具菜单--》库程序包管理器--》程序包管理器控制台(如果没有“库程序包管理器”的菜单,就先点那个“扩展管理器”,安装一个叫“NuGet程序包管理器”,然后就会有了。),点击后下面会出现一个连接PowerShell的控制台,等控制台加载完毕后输入

install-package App_BrowsersUpdate 回车

等待安装完成后,网站根目录下面会出现一个App_BrowsersUpdate目录。然后再访问就不会出现“__doPostBack未定义”的错误提示了。

使用VS2010的话,根目录会出现App_Browsers这个目录,如果使用IE11的还是会出现“__doPostBack未定义”的错误提示了。

打开App_Browsers=》ie.browser=》

加上如下这段代码:
