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:

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();
</script>

All this time I was testing my sites only in IE6 until my friend told me it wasn't working in FireFox. So I have to make changes in my Javascript code. In the Javascript console all the errors are pointed at the window object in all lines. alert(event.type) gives event undefined. Then I tried Event.type because I read somewhere that mozilla reads it as Event while IE as event. But then it gives:
Error: document.Event has no properties
Source File: http://localhost/xxx/xxx/xxx.js
Line: 3
Any idea of what I should be doing for it to work in FireFox ? The site works perfectly fine in IE until someone told me that IE doesn't follow w3c rules.

I use the following script in order to show/hide a section, and at the same
time to change a companion .gif with another:
function doExpand(paraNum,arrowNum){
if
(paraNum.style.display=="none"){paraNum.style.display="";arrowNum.src="../../images/arrOn.gif"}
else {paraNum.style.display="none";arrowNum.src="../../images/arrOff.gif"}
}
and then in the body:
<div id="reltpc"><a href="javascript:;" onClick="doExpand(xplan1,ico1)"><img
id="ico1" src="../../images/arrOff.gif" alt="" width="10" height="9"
border="0"> Show Info</a></div>
<div id="xplan" style="display:none" onClick="doExpand(xplan,ico1)">
<p>text here</p>
<p>some more text here</p>
</div>
Furthermore, two more scripts are used in order to show/hide a section
without the image:
function doSection (secNum){
if (secNum.style.display=="none"){secNum.style.display="block"}
else{secNum.style.display="none"}
}
function noSection (secNum){
if (secNum.style.display=="block"){secNum.style.display="none"}
}
and then in the body:
<div id="more"><a href="javascript:;" onClick="doSection(dtails1)">More
Info</a></div>
<div id="dtails1" style="display:none" onClick="noSection(dtails1)">
<p>text here</p>
<p>some more text here</p>
</div>
All three of them are working good in IE and Ffox, however the second claims
to use "gelElementById" instead.
Well, how could it be done? Would you help me please, to get that
conversion?

I have a php page with a drop down list, and the default selected
option is "Select a location" (without quotes).
Using the drop down initiates a database query. One of (3) things
should happen:
1. If an option is selected for which results are available, they
should be displayed on the same page beneath the drop down list in a
table.
2. If an option is selected for which results are NOT available, a
message should be displayed informing the visitor that there were no
results for that query.
3. If the default selected option has not yet been changed (ie: when
the page first loads), no message should display.
#1 and #2 work, but the message described in #2 is still displayed when
the page first loads before the default selected option is changed (#3)
but in Internet Explorer only. Firefox displays the page correctly
under all three conditions.
The message that I want hidden on page load is wrapped in a div named
"infobox" and I'm using the following script to hide it which is at the
bottom of the page:
<script language="javascript" type="text/javascript">
function ClearDiv()
{
if
(document.form2.name.options[document.form2.name.selectedIndex].value=="Select
a location")
{
document.getElementById("infobox").style.display =
"none";
}
}
ClearDiv();
</script>
I've also included the php code that writes out the message and the
table below....

I have a section of Javascript code that works a treat in IE but does nothing in Firefox. If we remove the doctype it appears to work, put the doctype back in and it breaks. We need the doctype to remain in so the page renders correctly cross-browser. Code:

Usually it's the other way (IE works, Firefox not working)... but here it is. IE does render something, although it puts the advert script (starting on line 9) at the very end, after the close of the last table. Firefox displays it as I have intended it (Ad inside the table). Code:

I have some code, using all the DOM documentation in the developer.mozilla.org website. For some reason it's only working in the newest Firefox 2 versions, and not 1.5.0.x
I'm having a hard time finding any documentation of what's not supported.
Can you guys help me? Here are the functions I'm calling:
getRangeAt();
range.collapsed
document.createElement("div");
range.cloneContents();
element.appendChild(clone);
document.getElementById("divid");
do you think it's createElement div? Maybe I can't create a div element?

I've got a page that creates an iframe and uses javascript to write to it.
Works like a charm in IE but not Firefox.
<script language="JavaScript"><!--
document.write ('<iframe width="100" height="100" name="myframe" src="blank.htm" FRAMEBORDER="1" scrolling="no"></iframe>');
document.frames[0].document.open();
document.frames[0].document.writeln('<html><head></head><body>');
document.frames[0].document.writeln('YO!</body></html>');
document.frames[0].document.close();
//--></script>
What I get in IE is the "YO!" written to the iframe. What I get in Firefox is the 404 not found page of the site where the original "jstest.html" page and script are hosted.

I have a page with words within TH tags. When you put your mouse over the entire table, it is supposed to change an image source location to the one in the onmouseover as well as a block of text. I keep getting undefined errors though. I've been unsuccessful googling for the past hour for the proper syntax for accessing the span and image properties in mozilla. I tried adding document in front of each monument, mainimg, and maintxt without any luck. It has worked fine in IE6.....

I've been using the very cool Transmenu javascript drop down menu that I heard about on this forum. Below the menu is a flash movie that I set to 'transparent' so that the menu will display on top of the movie. This works GREAT on internet explorer, however I've recently become a big fan of firefox and the menu still seems to fall behind the flash movie in that browser.
Has anyone had experience with this issue? I could really use a solution here to get the menu to display on top of the flash.

I have a DataTable that I created in C# that looks like.
Column1 - Column2 - Column3
1 - a - b
2 - c - d
3 - e - f
Now if I want to get the value of column 3 with id 3 I simply need to
do something like this (pseudo-code):
string value = dt.rows[3]["Column3"].ToString();
Is there a javascript object that mimics this same functionality? I am
going to use my C# DataTable to create a javascript object that I can
use for client-side functionality before posting back to the server.

Is it possible to have a JavaScript object that works just like a
standard Array, except that when the array is modified, a function
gets called which can then do some processing on the array?
Like this:
// SpecialArray has a function called Notify
function Notify()
{
// process the array with changes made
}
var myarray = new SpecialArray("zero", "one", "two", "three");
myarray[1] = "ein"; // after this change is made, function "Notify"
is called
I know you can derive a new object from Array, but you cannot directly
override the [] operator.
Can you add a function or event handler to a regular Array object that
gets called when the array changes?
