Internet Explorer Vs. Firefox Javascript Array Performance

Oct 10, 2006

I am trying to complete a javascript application and am having problems
with code similar to that show below.

Much testing has shown that Firefox finishes the code shown in around
0.25 secs but Internet Explorer 6 takes a massive 3.5 secs! Internet
Explorer 7 gets it down to around 2 seconds - but that's still 8 times
slower than Firefox and way unacceptable for my userbase.

Looking through the newsgroups there is some discussion around the
differences between the way the two browsers handle arrays - but a
performance differential such as this is just unbelievably dismal.

Unfortunately I need to continue to use arrays of objects and have to
support the Internet Explorer client base. I have already added
specification of the array size and also removed the use of array
"push"ing - flattening the array is not really an option. Code:

SetInterval Working In Firefox But Not In Internet Explorer

Apr 2, 2009

I am entering the so far very exciting world of javascript. However, I am perplexed at the following. I am setting a function to run every second with 'setInterval("runMonitor()", 1000)'. This works magically in Firefox, however works exactly one time in IE6 and then stops.

Code:
function runMonitor(){
var rflag = <?php echo $jsonopt; ?>;
if (rflag == "1"){
return 0;
}

updateSystemUptime();
updateInstanceStatus();
/* updateSystemStatus(); */
} setInterval("runMonitor()", 1000);

Simulating Internet Explorer Behavior On Firefox

Mar 4, 2010

I've recently transitioned from kubuntu to slackware 13.0. I find that although crossover could "run" a fully functional Internet Explorer session on kubuntu, there are all kinds of problems getting IE working correctly on slackware. (with wine or crossover). This begs the question: Is there a firefox plugin that would enable me to test javascript on firefox as if the javascript were on IE? If not, I'll be that I am not the only developer that could use such a feature.

AJAX :: Working With Firefox But Not With Internet Explorer

Mar 28, 2009

Here's another cross-over issue between the two browsers: IE and Firefox Please, take the time to view my test website: www seemyinvestments dot com I suggest you use Firefox first, Note the first page will be the index.php for the very website itself. Please, scroll down the source code file until you see the following line: $mainframe =& JFactory::getApplication('site');

Note the word, JFactory, is underlined, and the word, getApplication, is in green. Clicking on either word will successfully invoke a AJAX function in Firefox. For example, a popup window will appear in the upper-righthand corner of the browser if you click on the green word, getApplication. (The popup has test data in it so it doesn't make any sense right now.) Clicking on the word, JFactory, will display that source code file using AJAX....quick and clean.

With Internet Explorer, this is all suddenly broken! I swear it worked as good as in Firefox, and now suddenly nothing happens. With IE, two runtime errors occur. One Syntax Error, Line 214, and the other is a 'Expected Identifer' error, Line 4114. How the heck can I track down these errors? (What's out there an IE equalvent to FireFox's Error Console??)

Play A Sound In Firefox 8 And Internet Explorer 9

Dec 16, 2011

I wrote the following small HTML page, trying to play a sound in Firefox 8 and Internet Explorer 9. The button and the <a></a> link work fine, but calling from the <script></script> tag does nothing. Does anybody know, what can be wrong, and what I can do? I'm sorry, you have to supply the oef.wav file, since I can't upload it.

Document Object Is Not Set In Internet Explorer - Works In Firefox

Jan 11, 2007

I have a script that works in Firefox but not IE6-

<script language="JavaScript" type="text/javascript">
document.Params.ThisPageURL.value=document.URL;
var x = new Date ();
document.Params.TimeZoneOffset.value =x.getTimezoneOffset();
document.Params.submit ();
</script>

The form is set this way:
<FORM ACTION="<?php echo("$Action"); ?>" METHOD="POST" NAME="Params"
<input type="hidden" NAME="ThisPageURL" value=""><input type="hidden"
Name="$ERR" value=""><input type="hidden" name ="TimeZoneOffset"
value=""><input type="hidden" Name="$U" value=""><input type="hidden"
Name="$R" value=""><input type="hidden" Name="$T" value="">

I get the following error in IE:
document.Params.ThisPageURL is null or not an object

Any idea what the problem is ?

Jquery :: Nivo Slider - Firefox Versus Internet Explorer 9

Apr 7, 2011

I have used the Nivo Slider on my website: [URL]. It displays just fine on Firefox but not on IE9, it displays it as if all the images are stacked on top of one another going down the page, but the images don't actually display. Only when I turned on compatibility view on IE9 that the page works properly. I have tried placing the javascript:
Code:
<script src="[URL]" type="text/javascript"></script>
<script src="[URL]" type="text/javascript"></script>
<script src="[URL]" type="text/javascript"></script>

Between the <head> tags but then it doesn't load. It only loads if I add them into the page. Above my slider:
Code:
<div id="slider" style="width: 400px ! important; height: 300px ! important;"><img src="[URL]frontpage1.jpg" border="0" alt="frontpage1" /> <img src="[URL]frontpage2.JPG" border="0" alt="frontpage2" /> <img src="[URL]frontpage3.jpg" border="0" alt="frontpage3" /> <img src="[URL]frontpage4.jpg" border="0" alt="frontpage4" /> <img src="[URL]frontpage5.jpg" border="0" alt="frontpage5" /><img src="[URL]frontpage6.jpg" border="0" alt="frontpage6" /><img src="[URL]frontpage7.jpg" border="0" alt="frontpage7" /><img src="[URL]frontpage8.jpg" border="0" alt="frontpage8" /><img src="[URL]frontpage9.jpg" border="0" alt="frontpage9" /><img src="[URL]frontpage10.jpg" border="0" alt="frontpage10" /></div>

Ajax :: Working In Google Chrome But Not FireFox And Internet Explorer?

Nov 17, 2010

It works in Google Chrome but not Firefox and Internet Explorer. My computer has blocked Opera and I don't know how to change that. Too much energy to investigate now, I'll do so later.I'm assuming GoogleChrome is fixing a syntax error that FF and IE don't.

var request;
request=false;
try {

[code]....

has the problem. When I set up alerts to see what works and what doesn't, this code seems to be causing the FF and IE to not work, but I can't tell what it is that's causing them to fail.This is javascript that is suppose to check if a name has been taken by another user.

I'm working on a fairly large project that I wish to be the new formspring, (size wise) I procrastinated for 2 weeks of my 12 week break and now that I'm just getting started on it I'm running into an ishness load of problems...

[Internet Explorer] Cache Pbl With A Popup

Jul 23, 2005

I have a problem, and maybe someone knows the solution.

Context :
- Browser : IE 6.0
- Application server : Livewire Pro
- Client OS : Windows 98 SE
- Server OS : NT4
- I have a frameset, including several pages, but only one will be
used for the example.
--------
| a |
--------
| b |
--------
- a form on the main page (a.html i.e.)
- a data is manually typed, then I submit the form => the action will
redirect to a new page (c.html)
- on this new page, I do a history.go(-1), so I'm back on the a.html
page, and the data is still there (it's ok)
- cache parameters : "check on every page visited"

Problem :
- From the main page, if a popup gives the data to the form, so after
the submit and the history.go(-1), the form contains NO data !!!

So, the data is lost when the data input is not made by hand.

I have no troubles with Netscape/Mozilla, but only with IE.

Maybe someone would have an idea ?

Internet Explorer And Radio Problem

Jul 23, 2005

I have a radiobutton group in HTML in a form:

Sex: <input type="radio" name="Sex" value="male">Male

<input type="radio" name="Sex" value="female">Female

<input type="radio" name="Sex" value="unknown">Unknown<br>


When I call document.forms[0].elements['Sex'].type I don't get "radio" but
"undefined" instead.

For all other kinds ("text", "textarea", ... etc) of input fields the type
is returning a correct string.

It only seems to happen with Internet Explorer (using version 6).

What am I doing wrong?

Mozilla Faster Than Internet Explorer

Jul 23, 2005

I've developed a calendar program in javascript, and up until now I've
done most of my testing using Mozilla and Firefox. Everything works
fine, but when I try to use Internet Explorer my response time is
sometimes 50 times slower than using Mozilla.

I know I haven't given you much to go by, but I'm not looking for an
answer so much as an approach to debugging the problem. For example,
does anyone here know of a good web site which deals with
browser-specific javascript performance issues?
