Showing a message to IE 5+ users (yes, the browser detection question again)

[petermichaux]

Hi,

I would like to display a message to Internet Explorer clients to
encorage them to get Firefox. Yes they may like Internet Explorer but
it is my site :)

http://www.explorerdestroyer.com/ uses navigator.userA gent

If ((ua.indexOf('m sie') != -1) &&
(ua.indexOf('op era') == -1) &&
(ua.indexOf('we btv') == -1)) {
/* show message to IE users*/
}

I'm sure there is a better way to do this general detection. I vaguely
remember seeing a post with a huge long if conditional testing many
different objects to determine a very specific version of IE. I think
Richard Cornford wrote it. I just spent an hour (literally!) searching
the archives and couldn't find the post unfortunately. It may have been
along the lines of the following but very extended.

if (window.ActiveX Object &&
document.all) {
/* show message to IE users*/
}

I wish I had bookmarked that post because I am generally curious to
learn more about different versions of Internet Explorer and which
features distinguish it.

I would like to detect IE 5 and newer. Any suggestions or anyone know
about this post?

Thank you,
Peter

in header's javascript :

var IE = false; /*@cc_on IE = true; @*/
if(IE &&
confirm('Be careful you don't use correct browser !\n'+
'Won't you try to get the most out of the Web ?\n'+
'FireFox is for you'))
window.open('ht tp://www.mozilla.com/firefox/');
or in the page :

<div style="display: none" id=IE>
<h1>Be careful you don't use correct browser !</h1>
<h2>Won't you try to get the most out of the Web ?</h2>
<p><a href="http://www.mozilla.com/firefox/" target="_blank" >
FireFox is for you</a></p>
</div>
<script type="text/javascript">
var IE = false; /*@cc_on IE = true; @*/
if(IE) document.all['IE'].style.display= 'block';
</script>
nota :
/*@cc_on IE = true; @*/
detect all IEs even IE Mac
@cc_on ... @
is code in exclusive M$ script !
hidden to other browsers with /* ... */

Hi ASM,

var IE = false; /*@cc_on IE = true; @*/

/*@cc_on IE = true; @*/
detect all IEs even IE Mac
@cc_on ... @
is code in exclusive M$ script !
hidden to other browsers with /* ... */

This is very cool. What does @cc_on ... @ mean? @ is some special
thing? Do those letters cc_on stand for something meaningful?

It successfully detects IE 4, IE 5, IE 5.5, IE 6 on XP and IE 5 on OSX.
It also leaves the IE var false for Opera 8.5, Opera 9, Firefox 1.5 on
XP and Opera 9, Safari 1.3, Safari 2, Firefox 1.0, Firefox 1.5 on OS X.

Do you know if this will continue to work in IE 7?

Thank you,
Peter

Conditional Comment

It successfully detects IE 4, IE 5, IE 5.5, IE 6 on XP and IE 5 on OSX.
It also leaves the IE var false for Opera 8.5, Opera 9, Firefox 1.5 on
XP and Opera 9, Safari 1.3, Safari 2, Firefox 1.0, Firefox 1.5 on OS X.

Yes, Conditional Comments still work in IE 7.

@cc_on starts Jscript language (Jscript statement)

It successfully detects IE 4, IE 5, IE 5.5, IE 6 on XP and IE 5 on OSX.

XP and Opera 9, Safari 1.3, Safari 2, Firefox 1.0, Firefox 1.5 on OS X.

No reason it will not.
because, as I said, there you speak Jscript (M$ javascript) unknown by
other browsers.

ask to google : @cc_on

No, it doesn't. To quote your own resource:

<quote>
The @cc_on statement activates conditional compilation in the scripting
engine.
</quote>

It does not start JScript language.

Something like that, but it sure as heck doesn't "starts Jscript language".

Seems to me that wherever dates are inserted into news messages that
the timeszone should be included. If other posters insert similar
unqualified data, I expect the times as represented in text to be out
of sync with the actual flow of events.

Perhaps you could add a timezone? That might also give a hint on how
to interpret the date where the day date value is less than 13 - an ISO
format would reduce confusion further.
