How Much Effort To Put Into Supporting Pre-DOM Browsers?
Jul 23, 2005
I went through the past six months or so of entries
in c.l.javascript, and found a couple where people
had expressed opinions about the value of supporting
much older versions of Netscape and IE. The entries
included incidental mention of server logs showing
how many pages had been retrieved by such browsers.
I'd like to get some sort of communal variety of
opinions on how much effort it's worth to put in the
support, or in some cases, the "graceful degradation"
allowing partial capabilities to remain in a page
under the old browser.
My situation is that I have no access to server side
capabilities or CGI, have yet to buckle down and learn
Java, but have a fairly complex application I'd like
accessible via the web.
Are there links answering:
1. How many commercial sites still insist on full
compatibility? Allow significant degradation? Give
up on NN < 6? Ignore browsers with small market
shares?
2. How do developers feel about coding for browsers
older than, say, two years?
3. Are there statistics from a variety of sites
showing use by different browsers?

I just tested all the browsers I have for support of
document.documentElement.scrollLeft to determine how many pixels the
window has been scrolled to the right. I'm trying to determine if I
really need to go to all the trouble of feature detection for determine
page scroll amount of if the old browsers are old enough now just to
ignore them.
Below are the OS-browser combinations that worked in my test.
OS X 10.4
Safari 2.0.4
Opera 9.00
Firefox 1.5.0.6
OS X 10.3
Safari 1.3.2
Opera 9.00
Firefox 1.5.0.6
(Failed in Internet Explorer 5.2)
Windows XP
Internet Explorer 6.0.2600.000.xpclient.010817-1148
Firefox 1.5.0.6
Opera 9.01
IE 6 was released in August 2001 which is a long time ago so worrying
about IE 5 seems unnecessary for some kinds of web sites. And IE 5 on
OS X is a tiny fraction of people surfing the web.
Does anyone know which are the most recent browsers that would not
support document.documentElement.scrollLeft? Any mobile devices or are
they all running something based on Mozilla or Opera?

I want the list of browser which is not supporting Java Script.
So far I am thinking only JavaScript is the standard scripting language
supports in most the browser. Is any scripting language supports in all
browsers.

I'm programming a function that breaks a massive string (2 million + characters) into "manageable" chunks of 500,000 characters. The function goes as follows [code]...
As you can see, everything should work fine, and the function should return a stringified json array (which would be parsed and sent to a server) but the loop stops after the first interval. When I decrease the length of "v" using substr to 5 characters, the loop works fine. What could the problem be?

Why this code is not working on Webkit browsers:
Only jquery and the plugin printed above are loaded, so there shouldn't be any conflicts.
HTML:
Chrome gives the following error: Uncaught TypeError: Object #<an Object> has no method 'followUser

I have created a small application that lists all the
softwares that I created. This app was made using
Javascipts' DOM support of XML.
I am new to XML so I created this to get some experiance
in it. To problem is that the page only works with
Microsoft Internet Explorer.
Is it possible to modify the program so that it will
work with other Browsers? If yes, how? Code:

I used the DOM for mozilla to write some javascript. And naturally it doesn't work with IE and I haven't tried it on Opera type browsers. Is there any website that spells out the DOM's for IE and Opera individually like the mozilla one? Ie: http://developer.mozilla.org/en/docs/DOM:document.createElement
I would like to get the selection of the dom (meaning a highlighted area), then get the range. From the range I cloneContents in order to get a document fragment. Is there equivalent functions for IE and Opera etc? Code:

Why is it that most (well, honestly all that I have seen) the JS based modals, those that use frameworks like MooTools and JQuery, and what have you, why are most of the nifty visual effects like drop shadows and rounded corners, they don't work in Internet Explorer, but do work in FF, WebKit based browsers like Safari and Chrome, and Opera?
For an example, have a look at MooTools based MediaBox ( a LightBox "clone" ):[URL]..

On my site, I would like to open a centred pop-up with thumbnails. Clicking on them you get the full image with navigation arrows leading to new photos, etc.
I want to have pop-up dimensions suited to what's in the page and if the photo is vertical or horizontal.
Now, the code here under works well with FF2.0 and NS 8.0, but IE6 and Opera 9 just make the window.close() in func_aperta() and closes the pop-up.
What's wrong? Any ideas? Code:

I'm currently modifying a php controlled website and wish to distinguish between javascript and non-javascript browsers in order to decide which pages to display. I have a single php controller script which "includes" a number of html pages. I want to ensure that I cater for both javascript and non-javascript browsers (so functionality is the same, only the javascript pages have a far better look and feel to them).
Therefore I would like to code something along the lines of :
Code:
if (javascript_browser=='true')
{
include './javascript_page1.html.php';
exit();
[Code].....

I have a nice Javascript code which allows users to HTML format code in a textarea, similar to the code of Post New Thread page. It works great in Internet Explorer but it does nothing in other browsers.
It seems the problem resides in this two lines:
Code:
a=document.selection.createRange();
seleccio = a.text;
How can I arrange this lines in order to make them cross-browser? I really need this code to work, at least, in current versions of Netscape, Mozilla and Opera.

Does anyone see anything wrong with this code? It's a mystery to me why it works fine in all browsers but IE6/Win. Not getting any JS errors or anything to help debug.
<script type="text/javascript">
function submitGeoSelect ( geositeID )
{
var geoURL = "https://<?= $_SERVER['SERVER_NAME']?>";
switch ( geositeID )

I have been using document.cookie to write and read cookies.
Unfortunately, when I open my page in Internet Explorer, I don't see
what I wrote to my cookie while in Netscape Navigator. Similarly, my
page that I opened in Netscape doesn't see what I wrote to the cookie
while in IE.
Surely there must be away for IE and Netscape to read the same
cookie information ??. Otherwise, what happens if a user just happens
to be browsing my page in both browsers? They'll expect things to be
there, and they won't be there because one browser doesn't see what
was written in the other.
Any ideas on how to get Netscape to read cookies written by IE, and
visa versa?

First off by let me stating that I am not a great web devloper nor am I a good with css / javascript. I am creating this website for a friend of mines company and I have one problem.The problem is that the navigation menu on the right side will not remain fixed how i want it to be. I spoke with many people and they all said that this cannot be done with css considering your layout and because it needs to dodge the headers and the footer. I basically want this div (sidenav on the right) to scroll along the page as users scroll up or down but it can not interfere with the header or footer. I do not want the right side navigation to go over the content or out of the wrapper. I want it to stay in the same position in all aspects - left / right / top / bottom. Here is a link to the site [URL].

My navigation buttons have rollovers and are working fine in FF, Safari, Netscape, Camino but not in IE.
Not only that but there are some weird dashes appearing between some of the buttons. I do notice that the dashes disappear when I hover the cursor over some of the buttons. Can't figure it out... Code:
