I want to detect a users browser type IE, Mozilla firefox, or Opera and display the correct icon next to the user name. If its not one of the three above, Display another icon.

I have this so far document writing the name of the browser, but I want the icon then username only.
no sure how to write it.please help.

<tr>
           <td class='pformstrip' colspan='2'>$active[TOTAL] 
{ibf.lang.active_users}</td>
    	</tr>
    	<tr>
          <td width="5%" class='row2'><{F_ACTIVE}></td>
          <td class='row4' width='95%'>
            <b>{$active[GUESTS]} </b> {ibf.lang.guests}, <b> $active[MEMBERS] </b> {ibf.lang.public_members} <b>$active[ANON]</b> {ibf.lang.anon_members}
            <div class='thin'>
<SCRIPT language="JavaScript"> 
<!-- 
document.write(" "
+navigator.appName+ "+{$active[NAMES]}"); 
//--> 
</SCRIPT> </div>
            {$active['links']}


        </td>
        </tr>
        <!--IBF.WHOSCHATTING-->

PLease Assist with IF and Else Statements?

Have this so far, displays nicely in IE but not working in Firefox (not sure about opera or netscape)

Why is it not ok for Firefox?

<script type="text/javascript">

if ((navigator.userAgent).indexOf("Mozilla Firefox")!=-1) 
{
document.write("<img src='http://firefox.iprakash.com/images/browser_icons/firefox'></img>{$active[NAMES]}"); 
}
else if ((navigator.userAgent).indexOf("Netscape")!=-1) 
{
document.write("<img src='http://ca.ku.ac.th/images/netscape-icon.gif'></img>{$active[NAMES]}"); 
}
else if ((navigator.userAgent).indexOf("Opera")!=-1) 
{
document.write("<img src='http://www.dw-bg.com/img/opera_23_20.jpg'></img>{$active[NAMES]}"); 
}
else if ((navigator.userAgent).indexOf("MSIE")!=-1) 
{
document.write("<img src='http://www.aulapublica.com/categorias/Internet%20explorer.jpg'></img> {$active[NAMES]}"); 
}
</script>

My Firefox identifies itself as:

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1) Gecko/20061010 Firefox/2.0

So if you remove the 'Mozilla' or the 'Firefox' from your first if condition; it works ok. To be sure; go with:

if ((navigator.userAgent).indexOf("Mozilla")!=-1 && (navigator.userAgent).indexOf("Firefox")!=-1)

That will check for the navigator string containing the word 'Mozilla' and the word 'Firefox', but not neccessarily the phrase "Mozilla Firefox".

Thankyou Again Matt! I dont know how you found time to Learn so much, but Im glad You did Mate! :D

OK it works But momentarily, After a bit It Ceases Working For Some Reason? Help?

look like this now

<script type="text/javascript">

if ((navigator.userAgent).indexOf("Mozilla")!=-1 && (navigator.userAgent).indexOf("Firefox")!=-1) 
 
{
document.write("<img src='http://firefox.iprakash.com/images/browser_icons/firefox'></img>{$active[NAMES]}"); 
}
else if ((navigator.userAgent).indexOf("Netscape")!=-1) 
{
document.write("<img src='http://ca.ku.ac.th/images/netscape-icon.gif'></img>{$active[NAMES]}"); 
}
else if ((navigator.userAgent).indexOf("Opera")!=-1) 
{
document.write("<img src='http://www.dw-bg.com/img/opera_23_20.jpg'></img>{$active[NAMES]}"); 
}
else if ((navigator.userAgent).indexOf("MSIE")!=-1) 
{
document.write("<img src='http://www.aulapublica.com/categorias/Internet%20explorer.jpg'></img> {$active[NAMES]}"); 
}
</script>

Fails after next member logs on.

Personally, I'd lose the document.write():

<html>
<head>
<script type="text/javascript">
  function showBrowserLogo()
  {
    var strBrowserId = navigator.userAgent;
    var strImage = "";
    
    alert(strBrowserId);
    
    if (strBrowserId.indexOf("Mozilla")!=-1 && strBrowserId.indexOf("Firefox")!=-1) 
    {
      strImage="http://firefox.iprakash.com/images/browser_icons/firefox";
    }
    else if (strBrowserId.indexOf("Netscape")!=-1) 
    {
      strImage="http://ca.ku.ac.th/images/netscape-icon.gif";
    }
    else if (strBrowserId.indexOf("Opera")!=-1) 
    {
      strImage="http://www.dw-bg.com/img/opera_23_20.jpg";
    }
    else if (strBrowserId.indexOf("MSIE")!=-1) 
    {
      strImage="http://www.aulapublica.com/categorias/Internet%20explorer.jpg";
    }
  
    var objImage = document.getElementById('browser_logo');
  
    objImage.src = strImage;
  
    return;
  }
</script>
</head>
<body>
<img src="" id="browser_logo"/>
<script type="text/javascript">
showBrowserLogo();
</script>
</body>
</html>

I would also try and get the 'script' section I've put within the body into the body onload event (on that example it's easy =

<body onload="showBrowserLogo();">
<img src="" id="browser_logo"/>
</body>

)

That may come out better because (most) browsers always call the onload event when a page loads or reloads, (and browsers that don't remember the JS/DOM state of pages)

ok but how to associate it with each username, so the correct icon shows for each user? eg
Inny+IE icon
Fred+Firefox icon
Wilma+ opera icon etc ???

ah.. it wont do that for you automatically. it will only be able to work out the person viewing a page's browser..

if you want to asociate forum users with their browsers... you'll have to hack your forum program.

Matt, this one, seems to do that

<script type="text/javascript">

if ((navigator.userAgent).indexOf("Mozilla")!=-1 && (navigator.userAgent).indexOf("Firefox")!=-1) 
 
{
document.write("<img src='http://firefox.iprakash.com/images/browser_icons/firefox'></img>{$active[NAMES]}"); 
}
else if ((navigator.userAgent).indexOf("Netscape")!=-1) 
{
document.write("<img src='http://ca.ku.ac.th/images/netscape-icon.gif'></img>{$active[NAMES]}"); 
}
else if ((navigator.userAgent).indexOf("Opera")!=-1) 
{
document.write("<img src='http://www.dw-bg.com/img/opera_23_20.jpg'></img>{$active[NAMES]}"); 
}
else if ((navigator.userAgent).indexOf("MSIE")!=-1) 
{
document.write("<img src='http://www.aulapublica.com/categorias/Internet%20explorer.jpg'></img> {$active[NAMES]}"); 
}
</script>

but stops working after a new user logs on....??
