最近我们运营的网站有用户反馈在 IE 11 下<asp:LinkButton> 点击出现 “__doPostBack”未定义”,经过一番google,终于知道了原因:ASP.NET 可能无法辨识出一些浏览器的最新版本,还会经常把它们看做是低级的浏览器。(也就是: 不支持JavaScript。)
详见: http://blogs.msdn.com/b/scott_hanselman/archive/2011/10/28/asp-net-ie10-dopostback-javascript-ff5.aspx
本人按照该文所提供的解决办法始终未能得到解决,于是按提示尝试用单个站点的方式修复。
在项目根目录 App_Browsers 下新建 浏览器文件(.browser),让其与IE11的 UserAgent 匹配,使 .net framework 认识这是一个已知的浏览器,可以正常地向客户端输出脚本。
在文件里输入以下内容,保存即可。
