JavaScript - Redirect If Browser And Browser Version Is Safari 4 Or Newer.

Hello,

I have a question what is the best way to identify a browser, browser version and OS in javascript.

I have try a few scripts but they all fail. This will help me out formating the code for diferent browsers.

Thanks

i don't know what has changed in last releases of Firefox and Opera
but before i used this script to detect browser versions (IE, Opera, FF)
and block or redirect depending on version

Code:

 <script language="javascript">
 <!--

//Detect IE greater than 1 - we are blocking it completely
version=0
if (navigator.appVersion.indexOf("MSIE")!=-1){
temp=navigator.appVersion.split("MSIE")
version=parseFloat(temp[1])
}
if (version>1)
window.location="ie-error.html"


//Detect Opera less than 10 (9.80)
if (navigator.userAgent.indexOf("Opera")!=-1){
var versionindex=navigator.userAgent.indexOf("Opera")+6
if (parseInt(navigator.userAgent.charAt(versionindex))<9.8)
window.location="op-error.html"
else (window.location="index2.html")
}

//Detect Firefox less than 3.6
if (navigator.userAgent.indexOf("Firefox")!=-1){
var versionindex=navigator.userAgent.indexOf("Firefox")+8
if (parseInt(navigator.userAgent.charAt(versionindex))<3.6)
window.location="ff-error.html"
else (window.location="index2.html")
}

// -->
</script>

it worked last with Opera 9.5, FF 3.0
but after that it doesnt work at all
Firefox'es version (3.6) doesn't get detected and is redirected to error page
same goes with Opera (9.8 which is 10.0-10.5)

can anyone tell me why this happens ?
or can anyone "fix it"

i know many people are against this kind of scripts (blockers and redirecters)
but i do it so people who come with older and less compatible browsers with
W3C standards to get warned so they don't load deformed page

I can't seem to get any scrollbars on my Safari Windows Browser to display. I've tried removing my image height and width parameters but it doesn't make any difference.

I'm trying to popup a window and when the image is larger than the window, I want to be able to use the scrollbars to see the image.

My javascript code (pretty standard I think):

PHP Code:
 function popup_window(url,w,h)
 {
  var width=w;
  var height=h;
  var from_top=10;
  var from_left=10;
  var toolbar='no';
  var location='no';
  var directories='no';
  var status='no';
  var menubar='no';
  var scrollbars='yes';
  var resizable='yes';
  var atts='width='+width+'show,height='+height+',top='+from_top+',screenY=';
  atts+= from_top+',left='+from_left+',screenX='+from_left+',toolbar='+toolbar;
  atts+=',location='+location+',directories='+directories+',status='+status;
  atts+=',menubar='+menubar+',scrollbars='+scrollbars+',resizable='+resizable;
  window.open(url,'win_name',atts);
 } 



My calling PHP code as a link on the thumbnail image to be clicked on to popup the window:

PHP Code:
<A HREF="https://www.mysite.com/<?php echo $php_photo_filename?>" onClick="return popup_window('https://www.mysite.com/<?php echo $php_photo_filename?>', <?php echo $php_popup_width?>, <?php echo $php_popup_height?>)"><IMG SRC="<?php echo $php_small_photo_filename?>" WIDTH="<?php echo $php_small_width?>" HEIGHT="<?php echo $php_small_height?>" BORDER="1"></A>

Thanks for any help...

Hello forum! This script is supposed to redirect IE 5 to a page on my site.
However, the code is not doing the redirect part.
Take a look:

Code:

/*******************************************************************************
	OLDIE - or Old IE. A script that finds the version of IE you're using,
	and redirects if lower than the set parameter.
	[[ Created by Ryan McLaughlin, www.DaoByDesign.com ]]
*******************************************************************************/
var browser		= navigator.appName
var ver			= navigator.appVersion
var thestart	= parseFloat(ver.indexOf("MSIE"))+1 //This finds the start of the MS version string.
var brow_ver	= parseFloat(ver.substring(thestart+4,thestart+7)) 

if ((browser=="Microsoft Internet Explorer") && (brow_ver < 5)) //Change to suite
	{
	window.location="../oldie.html"; //URL to redirect to.
	}

I also would like to point out that the code belongs in a .js file.
NOT <script type="javascript".........

Hi all,

How could I make a web page redirect if the user is browsing in Internet Explorer 9.

Thanks in advance.
