How can I identify Safari?

[Giuseppe Chielli]

Hi to everyone? Can someone tell me if there is a way to identify
Safari...I found out that navigator.appNa me returns "Netscape" and I
didn't found any option to change the browser's definition...
I can use document.all for IE, and so on but what can I do with Safari?
I need to distinguish Safari from other browsers...

Thanks to everyone.

Reliably? I doubt you can. Why do you want to, anyway?

No, you can't. Opera and IceBrowser both support the all collection.
Other user agents might, too.

I very much doubt that. Your time would probably be better spent
learning how to implement feature detection. See section 4.26 of the
group FAQ, and its linked articles.

Safari can masquerade as many browsers, you can't reliably identify
it (nor most browsers) using appName.
didn't found any option to change the browser's definition...
A Safari user can change the user agent that Safari masquerades as,
but you, as an HTML/script author, can't.

Changing the browser that Safari pretends to be will not change its
support (or lack thereof) for Microsoft's proprietary (but sometimes
copied) document.all. There are DOM methods that provide the same
functionality that are implemented across a much wider range of
browsers, including Safari.

IE 6 implements pretty much all of them, IE 5 does most and 4 quite a
few. There are simple ways to allow for both MS proprietary and DOM
interfaces - read the FAQ:

You haven't provided any reasonable reason for needing to do so.

Thanks to everyone.

No problem. :-)

Because I need to prevent the bug of not getting window.innerWid th
property when a document is loaded in a frame... I see now that I can
test if this property is null or undefined... I just had to pay more
attention... ;)
Thanks anyway.

I told about that in a post and now I'll explain it better: I have a GIS
web application and the map image is in a frame; when the window is
resize, the Javascript code works for arranging the size of the image
and it does it using window.innerWid th property.
Because of a bug, in Safari this property doesn't return the correct
value if a document is loaded in a frame (it works properly only without
frames) so I'd like to prevent from resizing window when Safari is used.
I hope to have been clear...

Thanks.

Just fyi, you shouldn't need to fetch the 'pre-document' from the
server; a locally assembled one should do:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/str*ict.dtd">
<html>
<head>
<style type="text/css">

iframe {
display: block;
width: 500px;
height: 400px;
margin: 100px auto;
overflow: auto;
}

</style>
<script type="text/javascript">

function if_dummy(redir_ url)
{
//var HTML = '<body onload=location ="@"></body>'; <-- use this
var HTML = '<body
onload=setTimeo ut(\'location=" @"\',1000)>wait </body>'; /* demo only */
return HTML.replace(/@/, redir_url);
}

</script>
</head>
<body>
<iframe
src="javascript :parent.if_dumm y('http://www.google.com' )"></iframe>
</body>
</html>

Make that...

function if_dummy(redir_ url)
{
var HTML = '<body onload=location .replace("@")></body>';
return HTML.replace(/@/, redir_url);
}

Don't. It is not supposed to work and it is inefficient.
Make it

function if_dummy(redir_ url)
{
return '<body onload="locatio n.replace(\''
+ redir_url + '\')"><\/body>';
}

If that.
