Js Browser Detection & Correct Style Sheet Loading Help, Please
Jan 5, 2007
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'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.

I'm writing a reusable JavaScript library which needs to set certain styles in a document. The document may have an existing stylesheet definition either by a link or by an existing stylesheet declaration in the documents head section.
How can I use JavaScript to append my own style sheet information to a possibly already existing stylesheet definition?

It seems it's impossible to get a css style position from an external style sheet with JS, no?
<p id="testParagraph"></p>
if external css was:
p {
position: relative;
left: 20px;
}
apparently js cannot get
document.getElementById("testParagraph").style.left;
It seems it must be set as an inline css in the html or set by js explicitly in order to return the value. I don't get WHY it doesn't work.

I have a script that works perfectly on a live site that basically has a menu that reveals a hidden DIV and when you click a link, and then when you click a new link it hides the previous div and reaveals the new one. It is as follows:
Javascript Code:
Original - javascript Code
LastLayer = "nothing"; // the first div/layer
function openObject(theLayer){
// pass the name of the layer you want to bring to the top
// Then hide the last layer, and make the layer passed visible. This could have been done using the z-index property
if (document.getElementById) { // if it's IE5 or NS6 use this syntax to access the visiblity attribute
eval("document.getElementById(LastLayer).style.visibility = 'hidden'")
eval("document.getElementById(theLayer).style.visibility = 'visible'")
LastLayer = theLayer;
}
if(document.layers) { // if it's NS4 use this syntax to access the visiblity attribute
eval('document.layers[LastLayer].visibility = "hidden"')
eval('document.layers[theLayer].visibility = "visible"')
LastLayer = theLayer;
} .....
Now I am redesigning the site to work with a new style sheet, (There wasn't one before, it was all inline styles. Anyway, it broke my script. The CSS has a class that gives certain DIV's visibility attribute the 'hidden' value by default. I was planning on using the above script to reveal/hide them, but it does nothing. Here is the CSS that affects the divs I am referring to.
CSS Code:
Original - css Code
.job {
border: thin solid #000000;
float: right;
margin-right: 25px;
padding-left: 10px;
width: 40%;
display: none;
}
.job { border: thin solid #000000; float: right; margin-right: 25px; padding-left: 10px; width: 40%; display: none;}
As you can see there is nothing fancy in the css that would cause any concern.

I would like to create a function that will change the colour of a button when clicked then change it back at the end of the function. It works by capturing the backgroun color an then storing it as a variable. However it refuses to capture the original background color if the style is set via an external CSS style sheet. It only works if i set the style via the element markup. Am i doing something wrong and is there any way of capturing the style set by a external stylesheet?
Code:
function myFunction(el)
{
[code]....

I have found a solution for showing an element on page load (it should be hidden if JS is blocked), but the CSS and the JS go into the <head>. I prefer to keep all such code in external files, so how do I adapt it to support that approach? Found code is as follows (if it can be improved on, feel free to say so):
Code:
<script type="text/javascript">
document.write('<style type="text/css">#myDiv {display: block;}</style>');
</script>

I am using the stylesheet switcher on dynamic drive . Is there a way to change stylesheets based on a querystring parameter? Basically, if the query string includes "&StyleSheet=BlueStyle" then call and set the BlueStyle.css and cookie on page load.

I thought I'd try to begin with the accordion and tab, but I have had no success yet. I must be missing something simple. Here is the first test page:[code]Instead of getting tabs, I get my pages (generated by cgi perl scripts) displayed in tiny little scrollboxes at the top left.Equally bad, Firefox is telling me, in the error console, that jQuery.Tabs is undefined.FireFox doesn't like the filter and zoom properties in your style sheet.So, then, what do I need to do to get the tabs to work in the first instance. And then, how do I modify it to use an Accordion to display the same material. Are there any issues I need to be aware of when I start having my perl scripts (using predominantly the Perl packagesCGI and CGI::Session)create these pages?As far as possible, I am trying to keep this all valid HTML5, so that I can eventually make this interface mobile device friendly.

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>

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?

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 find I often have to change links in templates. I work for someone who is always wanting to alter their links. Is it possible to create a global template, or "master document" to link to as you would in a style sheet? This is what I want to do: Have 1 document that contains links. When I make changes to this document, all links on all pages would change also.

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) {

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?

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.
