I've never done javascript before but I need to be able to detect which browser the user is running. I've searched the net and copied some code to do this. It's simple and I understand what it does but I can't get the .html page to display different text per browser. This is what I have in my html:
<br />
<script language="JavaScript" type="text/JavaScript"><br />
<!--<br />
if(BrowserDetect()!="Internet Explorer")<br />
{<br />
document.write('Other');<br />
}<br />
else<br />
{<br />
document.write('Internet Explorer');<br />
}<br />
</script><br />
and this is the code that I found on the internet:
<br />
function BrowserDetect() {<br />
var detect = navigator.userAgent.toLowerCase();<br />
var OS,browser,version,total,thestring;<br />
<br />
if (checkIt('konqueror'))<br />
{<br />
browser = "Konqueror";<br />
OS = "Linux";<br />
}<br />
else if (checkIt('safari')) browser = "Safari"<br />
else if (checkIt('omniweb')) browser = "OmniWeb"<br />
else if (checkIt('opera')) browser = "Opera"<br />
else if (checkIt('webtv')) browser = "WebTV";<br />
else if (checkIt('icab')) browser = "iCab"<br />
else if (checkIt('msie')) browser = "Internet Explorer"<br />
else if (!checkIt('compatible'))<br />
{<br />
browser = "Compatible"<br />
version = detect.charAt(8);<br />
}<br />
else browser = "An unknown browser";<br />
<br />
if (!version) version = detect.charAt(place + thestring.length);<br />
<br />
if (!OS)<br />
{<br />
if (checkIt('linux')) OS = "Linux";<br />
else if (checkIt('x11')) OS = "Unix";<br />
else if (checkIt('mac')) OS = "Mac"<br />
else if (checkIt('win')) OS = "Windows"<br />
else OS = "an unknown operating system";<br />
}<br />
<br />
document.rs_browser=browser;<br />
document.rs_OS=OS;<br />
document.rs_version=version;<br />
<br />
return browser;<br />
}<br />
<br />
function checkIt(string) {<br />
place = detect.indexOf(string) + 1;<br />
thestring = string;<br />
return place;<br />
}
When I view my page in either FireFox or IE it doesn't generate any errors but it also doesn't display any sort of text.
Please Help,
Rob Tomson

Try moving the first two lines of the BrowserDetect function -
var detect = navigator.userAgent.toLowerCase();
var OS,browser,version,total,thestring;
- (ie the variable declarations) outside of the function - they are global variables (at least 'detect' and 'thestring' are also used in the checkIt function, so...)
cheers

That worked. Thanks! I guess I should keep an eye on what scope the variables are in.
Thanks,

Hi, I want to open a new browser window, let the user use that window for several minutes, and when they close, I'd like to change the page displayed in the original window.
According to numerous articles found Googling, this should work, but on my WinXP system, using Firefox and IE, I get nothing (when allowing pop-ups, if pop-ups are disabled, IE reports the window is closed, Firefox gives a JS error on checking the window handle). No JS errors, no notifications, nothing. Any pointers would be appreciated.
File 1 contains the code I'm using to open the window, to check for closure, and a form textarea that I update with the time (mostly so I know my timer is firing properly).

Dont know too much about FF, but very easy to get working for you in IE:

Thanks, but this requires modifying the remote page, which is not an option. I have no control over the pages being displayed in the remote window.

Hi, this will work in IE...
It is not a public standard so I don´t know how it works with FF.
<br />
var gRemoteWin<br />
function openWindow() {<br />
gRemoteWin = window.open("Test2.aspx", "remote");<br />
timer = setTimeout("checkClosed()", 5000);<br />
}<br />
<br />
function checkClosed() {<br />
if (!gRemoteWin.closed) {<br />
alert('exists...' + gRemoteWin);<br />
timer = setTimeout("checkClosed()", 5000);<br />
}<br />
else {<br />
alert('does not exist ...');<br />
}<br />
}<br />

It works fine with FireFox. My code would have worked also, if I used remoteWin.closed instead of remoteWin.Closed.
Thanks for pointing that out.

Hi,
I have a web page which has some table rows having background color. When I'm printing the page its not printing. I'm using IE 5.5 as the web browser. When I checked the Internet Options, the checkbox for Print background images and colors are not checked and when I checked this option and printed the page, the background color is printing. I need help for how to set the value of Print background images and colors checkbox to checked when I'm printing. I'm using only Javascript as the scription language and no database is used. If any of you have some ideas please send immediate response.

In what conditions the dialog ask for user name, password and domain will be triggered, after open IE for browing?
|

Hi there,
When the anonymous access is disabled for the web application, and the authentication mode is set to Windows, here I assume i'm talking about an ASP.NET application. For more information, you can see IIS Authentication[^]

Thanks for your reply!;)
Here I am just remake the environment. Our customer's environment.
In our development environment we have the direct access to internet, So there's no problem getting data from internet. But when it comes to our customer's environment it just didn't works, because the the way they gain access to internet. They have domain , they have proxy server, kind of complex environment.
They need to type the user name, password and which domain they're in in order to gain access to internet, but I just don't know how to remake it in our own environment!

How does your application access the resources on the internet? Does it use the WebRequest to create HttpWebRequest?
|
|
|
|
|
through the
CInternetSession
CHttPFile
|
|
|
|
|
I'm not familiar with the MFC stuff, but in this case you need to specify the proxy server before accessing the resources on the internet. You may look at the parameters in the object constructor, or you can post this question in the C++ forum.
|
|
|
|
|
Actually the implement is not urgent, What I need the most is to mimic the environment!That is when everything set up, once I open IE for browing, I'll get a dialog box asking for user name, password and which domain you're in!
|
|
|
|
|
|
|
There is a setting in the Http stuff you are using to tell it to use the existing IE settings when connecting. That would do the trick.

Hey minhpc_bk,
If the user is already logged on to the network and authenticated, is there some way to set it up so that Windows authentication doesn't pop up the login dialog?
Matt Gerrans

Hi Matt,
It all depends on the browser the user uses to browse the application and the windows authetication mode applied to the application. For example, the ASP.NET application is using the Integrated Windows Authentication (best suited for an intranet environment), if the client uses the IE browser, then the login dialog does not pop up as the IE will first use the current Windows logon information to send to the server. If the authetication fails, the browser then prompt the user for a user name and password. For non-Microsoft browsers like FireFox ..., you may need to check their documentation, but AFAIK the FireFox by default prompts the user with the login dialog box.

Hi:
Later I find out that our customer's web environment is exactly the same as you said. They used ISA Server, your reply did help me thanks.
And now I trying to configure the our environment using ISA, in which I install the ISA Server on Win 2k Advanced Server(two network adapters installed, one is connected to the internet, one is connected to the Lan). The internal networks' IP range is (..167.0 - ..167.255) in ISA, the Lan network adapter's IP is ..167.10. . I pointed the client's proxy server to ISA's Lan IP. When everything is done, I really get promoted for a username and password under the basic authentication method!
But I wonder How to configure the client's username and password!
|

One of the scenarios here is to set up an ISA server in a domain, and what you need to do is to configure the system policy for the ISA server 2004. There are a couple of rules which can apply to the Authentication services, for example the Active Directory rule is selected. When a client in the domain wants to access the resources on the internet through the web proxy server(ISA server), he first needs to provide his account in the domain(username and password). The ISA validates this info against the domain controller to see if this is a valid account in the domain or not, then the client can proceed or has to provide a valid account. So the ISA server needs to be set up in a domain so that it can access the list of all accounts in the domain, then you can configure the rule in the way you want. You can take a look at this document for more information.
ISA Server 2004 System Policy[^]
Also, you can find the resources from the sites provided in my previous reply:

I have a mainpage that will load a ascx and within this ascx I have also a few RequiredFieldValidator. This work fine until I try to load a button server control to acts as a close window button ('X'). This button will try to dispose off the ascx but due to RequiredFieldValidator it does not postback and unload the ascx. How can I achieve this task with Javascript? Can anyone help?
TIA
