真的檢測瀏覽器支持Javascript是由C＃.NET 2.0或更高版本？

Question

我需要通過C＃.NET 2.0代碼來檢測瀏覽器是否支持Javascript。但Request.Browser.Javascript現在不適用於所有瀏覽器。

我真的需要其他的方式來檢測它，誰可以告訴我也知道這裏的每個人都有同樣的問題。

感謝:-)

Answer 1

請使用new HttpBrowserCapabilities().JavaScript代替

Answer 2

當你說C＃.NET 2.0的代碼，你指的是ASP.NET或Silverlight？我假設ASP.NET。無論如何，瀏覽器檢測是關於客戶端功能的相當不可靠的信息來源。你真的想找出什麼？如果您需要確保客戶端啓用了Javascript，則一種方法是包含像<noscript>This page requires javascript</noscript>這樣的html代碼。這是提供回退錯誤信息的一種非常常見的方式（即您的代碼需要使用Javascript才能正常工作）。

檢查此鏈接Scott Hanselman博客，它描述了您建議的問題。也可以看看這個MSDN鏈接。從MSDN

代碼示例：

private void Button1_Click(object sender, System.EventArgs e) 
{ 
    System.Web.HttpBrowserCapabilities browser = Request.Browser; 
    string s = "Browser Capabilities\n" 
     + "Type = "     + browser.Type + "\n" 
     + "Name = "     + browser.Browser + "\n" 
     + "Version = "     + browser.Version + "\n" 
     + "Major Version = "   + browser.MajorVersion + "\n" 
     + "Minor Version = "   + browser.MinorVersion + "\n" 
     + "Platform = "    + browser.Platform + "\n" 
     + "Is Beta = "     + browser.Beta + "\n" 
     + "Is Crawler = "    + browser.Crawler + "\n" 
     + "Is AOL = "     + browser.AOL + "\n" 
     + "Is Win16 = "    + browser.Win16 + "\n" 
     + "Is Win32 = "    + browser.Win32 + "\n" 
     + "Supports Frames = "   + browser.Frames + "\n" 
     + "Supports Tables = "   + browser.Tables + "\n" 
     + "Supports Cookies = "  + browser.Cookies + "\n" 
     + "Supports VBScript = "  + browser.VBScript + "\n" 
     + "Supports JavaScript = "  + 
      browser.EcmaScriptVersion.ToString() + "\n" 
     + "Supports Java Applets = " + browser.JavaApplets + "\n" 
     + "Supports ActiveX Controls = " + browser.ActiveXControls 
       + "\n" 
     + "Supports JavaScript Version = " + 
      browser["JavaScriptVersion"] + "\n"; 

    TextBox1.Text = s; 
} 

我強烈希望能解決你的問題。
