Differences Between Firefox And IE?
Feb 7, 2011
I'm familiar with Java so I shouldn't be too lost. What I'm about to do is add support for a web app from Firefox to IE that uses OpenLayers.
I've searched and found a link to this site from another thread which had a list of supported functions and what not here: [URL]
From what I've read in the last hour it seems as though I will have to use some browser sniffing (isMozilla, isIE8, etc) and have multiple conditions (if-else's) in my functions to use the proper calls. Does anyone have extra material that contains differences between IE and firefox? Someone mentioned to me that in lists IE doesn't support trailing commas but ff does..

Does anyone know why the following code would work perfectly in FireFox but error out in IE7?
function readPageNumber() {
var split1 = document.cookie.split("=");
var split2 = split1[1].split("/"); <-- This is the line that errors
var split3 = split2[4].split(".");
var page = split3[0];
return page;
}
The error reads:
Error: Ƈ' is null or not an object.
So why does FireFox execute the code correctly and IE7 does not?

This is what im trying to achieve. At the top of my page there is some
search functionality, through which you cause to be loaded a string
representing an HTML page. Below this and occuupying about 80% of the
window real estate, there is a DIV. There is also a toggle button with
two options "Code View" and "Text View" as I have named them. Depending
on which mode you are in, you can see the block of HTML either as code
(in other words the tags are not rendered. You see the HTML as it
exists.) or as text (rendered HTML). Consider the following code, which
is a simplified version of the page.
<script language="javascript">
var mode = "code";
var s = "<html><head>
<style type="text/css">
My Stylesheet
</style>
<title>
MyTitle
</title>
</head>
<body>";
function ViewDoc()
{
if(mode == "code")
document.getElementById("docArea").innerText = s;
else
document.getElementById("docArea").innerHTML = s;
}
function ChageMode()
{
if(mode == "code")
mode == "text";
else
mode == "code";
}
</script>
<HTML><BODY>
<table>
<tr>
<td>
<input type='button' onclick='ViewDoc()' value='View Document'>
<input type='button' onclick-='ChangeMode() value='Change Mode'>
</td>
</tr>
</table>
<div id='docArea'/>
</BODY></HTML
The variable s contains an actual example of some HTML im trying to
load here (with the contents of the stylesheet omitted.)
Now, the following works fine in Internet Explorer. It does not work at
all in Mozilla Firefox. In firefox, for example, I have to cut out the
stylesheet, or the entire page goes fubar. Without the embedded
stylesheet, the "text" view (rendered html) works just fine. But the
"innerText" does not work in Firefox, and im not sure how to replicate
it.

In Firefox 2, document.getElementById is returning an HTMLDivElement,
in IE 7, it is returning an Object.
For example:
<div id="errorTableDiv">
</div>
....
errorTableDiv = document.getElementById("errorTableDiv");
alert(errorTableDiv);
errorTableDiv.appendChild(someTableNode);
Firefox prints HTMLDivElement and lets me appendChild() later on
IE prints Object and gives an error on the appendChild()
I do not understand why this happens or what the most socially
acceptable way to fix it is.

Mozilla/Firefox seems to be wrong when rendered elements with sizes
given in percents and that are placed into another elements with
percentage sizes, if the content overflows them (of course, overflow is
set to the value of "scroll")
To check the written above please use the given below code:

The following code results in the exact same output. Is there an advantage to using i++ over ++i (or visa-versa) in the loop? :confused:
<script type="text/javascript">
var tarr1 = []; for (var i=0; i<10; i++) { tarr1.push(i); }
var tarr2 = []; for (var i=0; i<10; ++i) { tarr2.push(i); }
alert(tarr1.join(',')+'
'+tarr2.join(','));
</script>

I am having a problem with a script that I am writing and I believe it is centered within a piece of jQuery code. I have some code like this (simplified slightly):
$.get('news/testfeed.xml', function(data) {
$('record', data).each(function() {
var $link = $('<a></a>')
.attr('href', $('link', this).text())
[Code].....

I'm seeing a difference in behaviour between
window.onload = f();
and
<body onload="f();">
Specifically, window.onload appears to fire before all the elements of
the page have been rendered. As the difference is consistent across
IE/Moz/Opera, I'm assuming it's deliberate - can anyone point me
towards where this behaviour of window.onload is defined in the
documentation? TIA. Code:

I use the code below to show the year on my sites e.g. this page.
However, instead of 2005 it shows 105 in Firefox.
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
var year=time.getYear();
document.write("" + year + "");
// End -->
</SCRIPT>
Works fine in Internet Explorer.
How can I show the correct year in Firefox as well please?

First the code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<title></title>
<script type="text/javascript">
function TextScroll(scrollname, div_name, up_name, down_name, top_name){
[Code]...
When I use mouse wheel in Firefox to scroll contents of the DIV, memory usage in Firefox goes through the roof. Code above is a fully working page, if anyone would like to see what's up, just load it up, and start moving your mouse wheel in the area with text. You don't actually have to scroll the text, just moving the wheel back and forth in that DIV will do. Memory usage will start going up quite fast, and after you stop moving the wheel, it will finally come down a bit after a short while. I've highlighted in red the line where mousewheel event is registered for Firefox. I'm not sure if it's really a problem, but since Opera and IE don't have any strange memory usage, and Firefox does, maybe I did something wrong. In everyday use it shouldn't matter [don't expect to have kilometers of content to scroll], but anyway, it is a bit unsettling.

if ((window)&&(window.netscape)&&(window.netscape.security)) {
// OK, this is Gecko/Firefox or someone mimicing it so well
// that there is no way to catch it on the act.
}
But I need Firefox *1.5 or higher* or another (but sure) way to know
that this browser has native SVG support. Here I'm stock.
It seems there is window.navigator.productSub and on my Firefox 1.5
it's 20051111
But I'm not sure: this "build version" is going up guaranteed or it's
random like CLASSID? Also is the same Firefox release has the same
build for all platforms or not? mozilla.org seems silent.

I have a BETA site that I'm testing. It looks good/works fine in IE, but Firefox has some troublesome breakages that I can't figure out how to fix without breaking IE. The one I'm most concerned about is that I have a video player that was working a couple of weeks ago, and several revisions to the page later (not the video iframe), it's not. Works great in IE, but in Firefox, the controls in the video player are either sticky or do not work altogether. The video is called through an iframe (needs to be done that way by request) and the embed is as such:
<head>
<script type="text/javascript" src="swfobject.js"></script>
</head>[code]....
I have also tried it with the following parameter, and it still didn't work in FF, but it didn't seem to affect it in IE:
so.addParam("type", "application/x-shockwave-flash");
What kind of front page revision (the page containing the iframe) might have changed this? Is it a recent FF update?

The problem is every example, I find that it will work in IE but not Firefox
or visa versa, could someone please point me to a how to that will work with
both browsers. I just spent two weeks reading the Microsoft Press Book "XML

When I set the background colour of an element using
tdRef.style.backgroundColor and then read it back, Firefox always
gives rgb(r, g, b) regardless of whether I've used rgb(...) or #rrggbb
to set it.
If I use tdRef.bgColor to set/read the value, I always get #rrggbb
regardless of whether I've used rgb(...) or #rrggbb.
IE, on the other hand, when using style.backgroundColor reports back in
whatever format was used (either rgb(...) or #rrggbb), but, like
Firefox, always gives #rrggbb for the bgColor method.
My question is which method is most consistent across various browsers?
I want to use style.backgroundColor (since some browsers don't support
bgColor, I guess it's a legacy from the ver 4 browser days). If I
decide to use rgb(...), is it consistently supported by other browsers
or do some report in #rrggbb regardless? Code:

I have the script below, which is supposed to populate a text box
on a form which opened this popup window - it should then call a
function 'PostThisPage' on the opener document, and then close the
current window/popup.
This works ok in IE - can anyone please help me by pointing out what it
needs to become cross-browser compatible? It doesn't work in Firefox
1.0.
<script>
window.opener.document.forms(0).tbGoToDate.value = 񟭄-11-11'
window.opener.PostThisPage();
window.close();

Here is my problem in a nutshell: a script to model dynamic table
extension. It works under Firefox. But IE just aborts, complaining about
an "unknown runtime error" in the line with "innerHTML". Why?
<html><head></head><body>
<script language="javascript">
function extend() {
var tb = document.getElementById('thetable').tBodies[0];
var newrow = document.createElement('tr');
tb.insertBefore(newrow,tb.rows[tb.rows.length-1]);
tb.rows[tb.rows.length-2].innerHTML =
'<td>A</td><td>dummy</td><td>row</td>'
}
</script>
<table id="thetable">
<tr><td>1-1</td><td>1-2</td><td>1-3</td></tr>
<tr><td>2-1</td><td>2-2</td><td>2-3</td></tr>
<tr><td>3-1</td><td>3-2</td><td>3-3</td></tr>
<tr><td colspan="3"><a href="javascript:extend();">extend</a></td></tr>
</table>
</body>

JavaScripties:
On the HTML side, we load an IFRAME with a blank page:
<iframe frameborder="0" marginwidth="0" marginheight="0" scrolling="off"
src="about:blank" id="iframe_xml1!format_text"
name="iframe_xml1!format_text" width="90%" height=" 180 ">Your browser is
inferior and doesn't support IFRAMEs.</iframe>
Later, a button click populates this frame:
var iframe = window.frames[iframeName];
iframe.src = outputUrl;
That works on IE but not FireFox. Any tips?
