Our last article and badBrowser Script are very frequently visited and today i found this:

IE6 No more / Samples

A very nice warning for all Internet Explorer Users < Version 7.0

Nice but I think our script with browser detecting ist much better of course.
Anyway – nice roadmap in web 2.0

Hi there,

in the last days we relaunched our website (www.team-noir.net). We used the CSS Framework YAML and create a small website (6 pages). But i spent 4 hours just for bugfixing the  fxxxx Internet Explorer 6.0 and 5.5

They don’t know variables heights or transparent png’s … certainly you know this!

I was so angry about loosing this time for old, silly and unsecure browers …

So we decided to implement a small but important WARNING to all users with old browsers. I found a very nice script on think2loud.com

I just extended the browser-detection, you will find the hole skript >>here<<:

function badBrowser(){
if($.browser.msie && parseInt($.browser.version) <= 6){ return true;}
if($.browser.opera && parseInt($.browser.version) <= 9) { return true;}
if (/Firefox[\/\s](\d+\.\d+)/.test(navigator.userAgent)){
var ffversion=new Number(RegExp.$1)
if (ffversion<=2) { return true;}}
if ($.browser.safari && (navigator.appVersion.indexOf("1") != -1) ){return true;}
if ($.browser.safari && (navigator.appVersion.indexOf("2") != -1) ){return true;}
if ($.browser.safari && (navigator.appVersion.indexOf("3") != -1) ){return true;}
return false;
}

There are a few ways to detect the browser and correct version. Most problems i had with Safari – because i cant’t find any stand-alone Version-Code – so i had to workaround … and built 3 queries.

If you have an better an easier idea – please let me know!

You can check our Sites now with “old” Browsers (IE <=6, Opera <9, Safari <=3, Firefox <=2) and see what happens …

UPDATE (25.06.2009):

I have a new version for browser detecting. Now the “Opera Problem” is solved, every Opera <= Version 9.5 gets now the Warning-Popup, and not all 9.x versions.
(Thanks to Ulf )

function badBrowser(){
    if($.browser.msie && parseInt($.browser.version) <= 6){ return true;}                  //IE ab ver. 6.0

    if($.browser.opera && ($.browser.version *10) <= 95) { return true;}                //Opera ab ver. 9.5

  if (/Firefox[\/\s](\d+\.\d+)/.test(navigator.userAgent)){
    var ffversion=new Number(RegExp.$1)
    if (ffversion<=2) { return true;}}                                                   //Firefox ab ver. 2.0

    if ($.browser.safari && (navigator.appVersion.indexOf("1.") != -1) ){return true;}    //Safari ver. 1.0
    if ($.browser.safari && (navigator.appVersion.indexOf("2.") != -1) ){return true;}    //Safari ver. 2.0
    if ($.browser.safari && (navigator.appVersion.indexOf("3.") != -1) ){return true;}    //Safari ver. 3.0

    return false;
}
