问题

I need to separate IE and FF browsers from others

it\'s a pseudo-code :

If (CurrentBrowser == IE(6+) or FF(2+) )
{
...
}
else 
{
...
}

in protected void Page_Load() event (think so)

if ((Request.Browser.Type == \"IE\") || (Request.Browser.Type == \"FF\"))
{
    WebMsgBox.Show(\"1111\");
}

no effects :-/ what is IE and FF types?

回答1:

if (Request.Browser.Type.Contains("Firefox")) // replace with your check
{
    ...
} 
else if (Request.Browser.Type.ToUpper().Contains("IE")) // replace with your check
{
    if (Request.Browser.MajorVersion  < 7)
    { 
        DoSomething(); 
    }
    ...
}
else { }

Here's a way you can request info about the browser being used, you can use this to do your if statement

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";

Try the below code

HttpRequest req = System.Web.HttpContext.Current.Request
string browserName = req.Browser.Browser;

回答4:

    private void BindDataBInfo()
    {
        System.Web.HttpBrowserCapabilities browser = Request.Browser;
        Literal1.Text = "<table border=\"1\" cellspacing=\"3\" cellpadding=\"2\">";
        foreach (string key in browser.Capabilities.Keys)
        {
            Literal1.Text += "<tr><td>" + key + "</td><td>" + browser[key] + "</tr>";
        }
        Literal1.Text += "</table>";
        browser = null;
    }

回答5:

I would not advise hacking browser-specific things manually with JS. Either use a javascript library like "prototype" or "jquery", which will handle all the specific issues transparently.

Or use these libs to determine the browser type if you really must.

Also see Browser & version in prototype library?
