　　最近項目在 IE 11 下<asp:LinkButton> 點擊出現 「__doPostBack」未定義」，通過一番google,終於知道了緣由：ASP.NET 可能沒法辨識出一些瀏覽器的最新版本，還會常常把它們看作是低級的瀏覽器。（也就是： 不支持JavaScript。）javascript
詳見： http://blogs.msdn.com/b/scott_hanselman/archive/2011/10/28/asp-net-ie10-dopostback-javascript-ff5.aspx
本人按照該文所提供的解決辦法始終未能獲得解決，因而按提示嘗試用單個站點的方式修復。
在項目根目錄 App_Browsers 下新建 瀏覽器文件(.browser)，讓其與IE11的 UserAgent 匹配，使 .net framework 認識這是一個已知的瀏覽器，能夠正常地向客戶端輸出腳本。java
在文件裏輸入如下內容，保存便可。瀏覽器
