Browser Detection Code
Jul 20, 2005
I want to know the height of the viewable portion of a page (minus scrollbar)
in Opera and Mozilla.
For Opera, I could use document.body.clientHeight. Unfortunately, this won't
work in Mozilla because Mozilla also subtracts the sizes of the top and bottom
margins.
For Mozilla, I could use document.documentElement.clientHeight.
Unfortunately, this won't work in Opera because Opera returns the height of
the entire page, not just the viewable portion.
So I have two options:
1) Use browser detection code to determine if the user is running Opera or
Mozilla, and then use the appropriate clientHeight code.
2) Use window.innerHeight. This is supported by both Opera and Mozilla,
however it returns the height of the viewable portion of the page *including*
the scrollbar. Is there any way to determine the width of a scrollbar? If
not, then I would have to make an assumption and subtract the hardcoded width
of the scrollbar from window.innerHeight... but only if the scrollbar is
present, is there a way to determine that?

I am writing an application that (unfortunately) will work only with certain browsers and operating systems. Does anyone have a link to a good "browser/OS detection script"?
I'm looking for something simple that I can just include in each page of my html code, and us it like this:
if (! IE5.5+ for windows) {
fail
}

Simple JavaScript code for browser detection:
/**
* Browser detection
* @Created-On 2007-11-27 23:46:51
*/
function detectBrowser(){
if(navigator.userAgent.indexOf("Opera")!=-1){
return "Opera";
}else if(navigator.userAgent.indexOf("MSIE")!=-1){
return "MSIE";
}else if(navigator.userAgent.indexOf("Navigator")!=-1){
return "Netscape";
}else if(navigator.userAgent.indexOf("Firefox")!=-1){
return "Firefox";
}else if(navigator.userAgent.indexOf("Safari")!=-1){
return "Safari";
}
}

I'm going to make an attempt at coding a nice tree menu that is decent with browser support.
I want the tree to be displayed on all browsers (well, within a decent range). Of course, on older browsers, the menu won't be as functional.
Now, I'm going to be combining the javascript with a server-side language (asp.NET) and I'll be able to do some basic browser detection on the server.
But, I read about javascript object detection and am wondering how well that works exactly.
Like, what if a browser that doesn't support objects period tries to run some object detection code? Also, which browsers support user defined objects?
See, I'm thinking of breaking down the script in 3 categories. Browsers that won't get any javascript... these would be the browsers that don't support object detection, browsers with basic javascript... with these I would be able to code my own object and I would test for different features. And then there would be the browsers that can run it all.
So, basically, my question is what browsers support what features and how should I break down my code between them? A long time ago (back in the Netscape 4 / IE4 days) I did some javascripting, but since then I haven't really done any. I remember that NS4 didn't support div tags but supported layers... anyway, it got really messy.

So I need script, which will detect users browser, and if browser will be IE, then show some link in content, if browser is FireFox or Opera, then hide that link. Link looks like:
<tr>
<td align='center' valign='top'><a href='/' target='_blank'>link</a></td>
</tr>

I have some html code i would like to be printed to the page only if the
browser has javascript enabled. I have tried to use document.writeln()
but the string i want to print bot contains some ' and " in it. I don't
know how to set the delimiters of the string that is passed as argument
so that i don't get an error in the page.

I've have got this script, the only thing I want to be changed is the first part. It has to detect IE version 6 instead of just "Microsoft Internet Explorer". Can somebody help me out? I tried "Microsoft Internet Explorer 6" but that doesn't work.
<SCRIPT LANGUAGE="Javascript">
<!--
bName = navigator.appName;
if (bName =="Microsoft Internet Explorer") {
document.write('<link media="screen" rel="STYLESHEET" type="text/css"
href="stylesheet1.css">')
} else {
document.write('<link media="screen" rel="STYLESHEET" type="text/css"
href="stylesheet2.css">')
}
//-->
</SCRIPT>

Well after playing around a little I have created a solution that works although it appears a little chunky. The problem was finding the browser size to use the width as a variable for size conditional aspects to a site. Code:

I am looking for a detailed and correct browser detection script. Preferable a one that does not detect based on the UA string, but detects using DOM model or tests for functions, etc...
I'd like it to return OS, Browser and version as a separate variables.

I'm relatively new to jQuery and have just been learning the basics/playing around with plugins etc. I'm building a site that uses a jQuery page easing (where is scrolls smoothly down to an anchor element on the same page) - however, the script isn't working great in opera despite me trying all suggested fixes, so i have decided to have opera just page jump as per the default browser action.
My question is - Is there a way of a) detecting which browser the user is using and then if it's NOT Opera, writing the pageEase script to the page?
[Code]...

I have an html form where IE and Firefox work very differently. So, it'd be useful to know what browser is in use. I found this script and put it in my html code...
In the php I do a echo code... but it's always empty... I figure I've got something obvious goofed up, but what?
ALSO, when I run it in IE 8.0, on screen it says "Microsoft Internet Explorer", but it SAYS Browser version: 4 - But I'm using version 8.
AND, when I run it in Firefox version 3.5.5 it SAYS "Netscape" and Browser Version: 5.

I voluntarily contribute on eBay's member-to-member Photos/HTML community forums along with a handful of other contributors.We often have eBay members that post on the forums that have trouble uploading images to eBay for the items that they want to sell. To properly help and diagnose these member's issues, we need to know information about their system, such as the browser that they are using, browser version, Adobe flash version, etc.
I've been seeking for an online tool that can detect info regarding one's system. There are various tools online to detect detailed info about one's system, such as this one, but they either give out too much information, or does detect everything I'd like to see answered.
I would like to have a custom script made that will detect the following information:web browser
browser version, including sub-version
OS platform
adobe flash version, including sub-version
[code]....
the tool will detect the above information automatically, or upon user input, and send the info to a text box where the user can copy the generated info regarding their system and paste it on the forums for volunteer helpers to look at.

i've designed a site using firefox as my primary browser. (note: i'm on an old mac so limited to only what i can run on 10.2.8) i tweaked it for safari, and then took the stuff on a jump drive to the library and tweaked it for IE6 on a pc.
what i need to do now is either hack the CSS for safari and ie (and eventually others once i get some feedback); or, use javascript to load the correct style sheet.
i've just spent two days--thursday and today since since 10 a.m.--trying to figure out first the js, and then the hack methods to no avail. (well, more, really over the past few weeks, but the two-day immersion has me totally fried.)
i'm reached the point where time is extremely critical. once i get this out in an acceptable form, i can spend more time on the learning curve.
here is the document head code:

I am getting differences in the rendering between Safari and Firefox. I've tried to come up with a JS script to sort them out but I am not having much luck. Safari always produces "red", the same as FF or nothing at all (where I substitute 'vendor' for 'userAgent', etc). Here's my little test program to isolate the basic code:
<link href="testcss/ff.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" >
window.onload=detectbrowser;
function detectbrowser()
{
var browser_type=navigator.userAgent;
alert("the user agent is:" + browser_type);
var browser_type=navigator.userAgent.indexOf("AppleWebKit");
if(browser_type != -1)
{
document.write('<link rel="stylesheet" href="testcss/saf.css" type="text/css" >');
}else{
alert("no useragent verified");
}}
</script>
<!--[if lte IE 7]>
<link type="text/css" rel="stylesheet" href="testcss/ie.css" />
<![endif]-->
<title>Untitled Document</title>
</head>
<body>
<div id="testbox"></div><br />
<ul>
<li>Red is for Firefox</li>
<li>Green is for Internet Explorer</li>
<li>Yellow is for Safari</li>
</ul>
</body>
</html>
What's even odder, Safari won't even execute the ....else part of the if statement when I'm trying to detect using 'userAgent'.

[URL]If you go to that site on Firefox, the "Return Code #" expands. But if you use IE, you'll see that it doesn't.I could add a fix in there for the fields if they were static, but if you see my javascript, they are dynamically loading fields.
This "class":"wide" is not working:
Code:
invoiceInput.appendChild(createElement("input", {"type":"text", "name":"invoice[]", "size":"8", "class":"wide;"}));
I am using a script I found on a jQuery board [URL] and it works for them, but not for me because my syntax is probably wrong. And they also are just using 1 field and not near-unlimited dynamically loading fields like I am.How would I add in a fix to have the browser 'only' use the expansion if the user is using IE6 or IE7?

I'll be the first to admit, I am not skilled with javascript, but I can do a little work here and there. I remember learning there is a way to detect a user's/viewer's browser. Is there a possible javascript that allows me to detect a viewer's browser, the based on the browser, selects css/html to use so that the website is viewed correctly?

I have a chunk of jquery that is working in all browsers except IE.
I know it's possible to target a piece of code AT a specific browser but is there any way to EXCLUDE it from a certain browser?
I'd be happy for IE to just not see this chunk of code...?

I have a site where I'm using a home-grown social bookmarking tool. The user has an option to "Bookmark this page" to their browser.
My code works, but the problem is that when I dynamically grab the document.title, the browser (both IE and FF) tries to resolve any spaces or special characters so that when the favorite is stored in the browser, the bookmark reads:
"This%20Site%20Bookmark"
instead of:
"This Site Bookmark"
I feel like there must be a simple function to resolve spaces, but I'm coming up blank, no pun intended...:)
