Strange Behavior When Changing Select's Value
Jul 20, 2005
I expect to see "foo" for the 2nd alert. Instead, the value of select is
cleared. Am I missing something?
<html>
<head><title>Foo</title>
<script language="javascript">
<!--
function foo()
{
alert('Before change: ' + document.control.titleFont.value);
document.control.titleFont.value = 'foo'
alert('After change: ' + document.control.titleFont.value);
}
-->
</script>
</head>
<body>
<form name="control" method="POST">
<select name="titleFont">
<option value="sans-serif">Arial</option>
<option value="serif">Times</option>
</select>
<input type="submit" name="control" value="Submit" onclick="return
foo()"/>
</form>
</body>
</html>

Is there a way, besides writing another method, to make Date.setMonth() do something more useful than nothing when the month in question creates an invalid date? If I try
d=new Date();
d.setMonth( 1 );
today, I'd really like to get some kind of an error rather than silent failure.

I'm trying to create an array of dates two weeks apart from an arbitrary startDate, and I've noticed some odd behavior in my variables. I did a little experiment on my JS console and here's what I got. My inputs are in blue, the output is in black.
Code:
Everything's good so far, but here's where it gets odd. I try to add 14 days to cur.
Code:
Why is it that when I make changes to cur, the same changes are made to startDate?

It's the first time I read the following code.
A few js files like the one below, but I don't know how to make them
readable by a human ( me ).
Is it a strange character set ? an obfuscation ? both ?
Firefox or IE detects no errors, so the following code is run with no
problem.

I'm trying to send a byte array (JPG image) from javascript to a servlet for processing. I'm using Base64 to encode the byte array in javascript, and then a base64 decoder in the servlet to decode it.
The thing is, that even though the String has the same length on both sides, the decoded byte array is shorter then the original one. I've tried a couple of different implementation on both sides, with the same results.

Dont know how to put this. In my application i had one jsp where i did some modifications in the java script function and increased the maxlength of a field.
Just these two major modifications i did.But strangely everything got screwed up the function is not being called and many other java scripts func are not being called. Many buttons are not behaving strangely. That jsp is a very big one and a part of a major colossal application so i am not pasting it.

I have the following algorithm
1. Show message DIV
2. Long Loop Function
3. Hide message DIV
Opera shows DIV well. Firefox and IE don't show the DIV.
If to rewrite the algorithm like this Firefox and IE will show DIV
1. setTimeout(Long Loop Function,500)
2. Show message DIV
I also tried to debug the first algorithm in Firebug, and in step by
step mode I see that Firefox shows the DIVs.
Is it standart behaviour? What prevents browsers from showing the DIV?

I have javascript calculating the total price of all the products in a shoppping cart. The prices are in the format of 10.99 or 5.50 or 10 ete.g if there are five items bought for 10.99 and 1 bought for 10, the script will multiply 10.99 by 3, then multiply 10 by one, then add the two results.
The resulting number is sometimes right, but quite often it ads an extra '000000002' or so to the amount??

I've used the following simple javascript in a link to open a new window:
<a href="javascript:void(0)" onclick="window.open('images/tshirtback.jpg','TShirtBack','width=540,height=660')">
This works and does as intended in all browsers other than (you've guessed it) MS IE wherby a 403 Forbidden error is generated. Anyone got any idea why this is the case and how I can get around it?

Yesterday I discovered a problem on one of my sites: escape function was encoding the same string Salò in two different ways:Sal%F2Sal%C3%B2
This was happening on Firefox 2.0.0.3. In Opera 9.20 was encoded ok every time.
So, in Firefox was a russian roulette . Sometimes was encoding the string like I wanted to, sometimes not. As a solution I use encodeURIComponent(), but the behavior of escape() seems strange to me.

I have a program that creates dinamically a web page. In the page I have the following function to check how many checkbox are checked.
function tarInfo(info) {
var i=0;
var c=0;
var l=document.forms[0].selected_files.length;
alert(l);
for (i=0; i<document.forms[0].selected_files.length;i++) {
if (document.forms[0].selected_files[i].checked) {
c++
}
}
..
..
The problem is that if I have only one checkbox, the alert(l) write
undefined. If I have more than 2 checkbox, the function works well.
Here a part of the webpage with one checkbox.
<form name="form1" action="filemanager" method="POST"
enctype="multipart/form-data" >
..
..
<td>
<input type="checkbox" value="pbsrun.o100"
name="selected_files">
</td>
..
..
<input type="submit" class="button" name="tar" value="Tar"
tarInfo('tar')">
Where is the problem?

I have set up a disclaimer page for our public access PCs at our Libraries which has the following function:
function breach() {
alert("Proceeding beyond these Conditions is..................... If you have read the Conditions, scroll to the bottom and press the 'Yes I
agree' button.")
window.location="disclaim.htm"
and then in the body tag I have onunload=breach()
This works fine for all websites entered into the address bar except if
you enter www.google.com
What it is supposed to do is bring up the prompt and when you click on the OK button it will go back to the disclaimer page. They should only be able to get to the web by clicking on the 'Yes I
agree' button at the bottom of the disclaimer page. Does anyone out there know why google doesn't fire up the disclaim.htm page like all the other sites? It is very frustrating.

We use WebSphere 6.1 as web server and the project is in ear file. After deployment, sometimes access server, the page was load incomplete, such as logo image (.gif) disappeared, and JavaScript error appeared. But after press on Refresh button from browser (IE), the page is loaded completed, all images are loaded and the JavaScript is gone.
[Code]...
We have tried to optimize the JSP page, however the page loaded is faster but this issue still occurred once in a while. Does anyone encounter the same issue before?

This is a support ticket, stating the fact if that IE not support the characte encoding or somehow misinterprets the encoding you will get a strange javascript error called:00ce56e.This will apply on all your ajax transfers for one.For example i had a text/html;charset=utf8 header returned from a php-webservice i wrote. Nice i though, charencoding is the "plant-shit" (Crank quote) and code along and thought to myself, "Damn i'm a witty one". until i started the "IE" beast.. the beast throw out all my claims and the lookout for actually winning this went down. Until i found the above URL.. That is some crackhed shit right there. (Crank anyone?!).What it's stating more or less is that if IE 7 or 8 (or any program that uses whatever that is located in what dll) would more or less shit its pants when it run over an unspported encoding.. In this case UTF-8..
Ok, i'm a swedish guy and uses windows iso latin craptastic charsets more or less everyday but when coding for internationally webpages that are targeting multiple countries you cant get to be staring blindly at your own chars by altering my header to a text/html instead of a text/html;charset=utf8 response to my ajax script i solved alot of strange error shit. (but not my previous post with the fact that IE dont succed even if it would want to, thats a total other question but related but not directly if you get my drift.)..

I'm creating a tabbed menu navigation for a site. I'm using javascript to to give the tabs a mouseover effect. I also have a function that decides whether the tab has been selected or deselected by the user, and uses that info to determine which image file to use in the img swap.
The page works fine in IE 6, however in Netscape 6.2, when I mouseover the tabs, a thin border quickly flashes around each image as it swaps. It looks like the placeholder that's displayed for a broken image in IE, only with only the border and no red "x". I'm not sure why this is happening, as all the images have been preloaded.
The markup is XHTML 1.0 Transitional. Here's the js I'm using:

I am playing with malsup's corners and I am getting strange nudges on both top corners in Opera, IE6 and Konquerer when applied to nested elements (to achieve a cornered border). I am using exactly the same code as on the demo page: "$(this).corner("round 8px").parent().css ('padding', '4px').corner("round 10px")". Strangely this only appears when the radius is more than 10px and
div.outer's padding is less than 3px. All corners are rounded, just at the top div.outer still seems to have little develish horns.

I have to change dynamically all hyperlinks, when the html-page is
loaded at the client. This works fine, except in the following scenario:
When the innerText of an anchor contains an '@', the InternetExplorer
changes the innerText-Property to the HREF-Property. I have checked this
with MoZilla/FireBird and Opera and there is no problem!
To explain, what i mean, see following example:
function atTest(){
for(var i=0; i < document.links.length; ++i)
{
document.links[i].href = document.links[i].href;
}
}
Now you need some anchor tags - notice the '@' as inner Text:
<a href="http://www.somelink.org/">Text before @ and after</a><br>
<a href="http://www.somelink.org/">Text before @</a><br>
<a href="http://www.somelink.org/">@ before text</a><br>
<a href="http://www.somelink.org/">Text before at and after</a>
If you load the page, InternetExplorer will display the HREF-Property
instead of "Text before @ and after" - all other elements are shown
correctly! It doesn't bother other browsers: Opera/MoZilla shows _even_
the first element with innerText.
My system: Windows XP SP1, InternetExplorer SP1, Firebird0.7, Opera 7.23
Has anybody out there an idea, why IE behaves like this? And how I can
work around this?

The point is, the combobox that receive the data from mysql, if I have a name with special character like "~" or "^" any other accent in the mysql, the combobox that receive this data appear a strange symbol like as in the file attached in the place of the letter that is with accent. The code that I have here is
$(document).ready(function(){ $("select[name=Empresas]").change(function(){
$("select[name=Unidades]").html('<option value="0">Carregando...</option>');
$.post("unidades.php",
{Empresas:$(this).val()},
function(valor){
$("select[name=Unidades]").html("<option>Selecione...</option>" + valor);
})})})

I've got a div, and it has an onMouseOver handler attached to it which makes a second div visible. The second div shares part of one side with the first, but not all.
The first div also has an onMouseOut handler which, you guessed it, makes the second div invisible.
However, if the user rolls out of the first div and into the second, I'd like to keep the second div visible. Any ideas how to accomplish this?

My question is regarding the behavior of Supersubs in IE6. It seems to adjust to the correct width, but, it applies the new width to all of
the parent UL's of the widest LI. In IE7 and FF the new width is only applied to the containing UL of the LI.
