FAQ - Why was my post not answered?
-----------------------------------------------------------------------
This could be for several reasons:
*
It was a variation of a frequently asked question and was
therefore ignored by everyone
*
No one knows the answer
*
The person with the answer has not seen the post
*
It might not be possible to do what you want to do but
perhaps readers of clj are reluctant to answer your post
in the negative when they are not convinced that it
cannot be done.
*
The question was not asked clearly enough, or included enough
information to be answered.
*
The questioner did not realise the need to read the group, for
a few days, to see the answers posted there
If it is not one of these, then after a few days consider
reposting after checking
http://groups.google.com/
for
replies. Make sure the post is phrased well, and everything
needed to answer is correct, and the subject is appropriate.

| Replace text in text box with innerhtml type thing Bobd314@Gmail.Com 16:18:44 |
| | Currently, I am having a problem replacing the value of a input box
with something else using the innerHTML thing. Right now I have
something going
<script type="text/javascript"><!--
function changeText(newText){
document.getElementById("WHATEVER").innerHTML=newText
}
//-->
</script>
and a link with
<a href='javascript:changeText("Hola Mi Amigo")'>Dont know</a>
and the text box like
<INPUT TYPE="TEXT" NAME="WHATEVER" id="WHATEVER" VALUE="TESTING"
SIZE=60">
and I am trying to replace what is enterd in the text box with "Hola Mi
Amigo." However, it doesnt seem to want to do it. Maybe I am doing
something wrong, but I have no idea what my problem is.

| can someone explain the cross domain security re AjAX in IE? Adrian 14:29:36 |
| | can someone explain the cross domain security re AJAX in IE?
I have a page that calls a web service (WS) from another domain (the target
browser is only IE6) and displays it's results! all works fine when the page
is run from my hdd, however when run from the web I get "Access denied" due
to the cross domain security (I assume).
So I set the browser setting to allow cross domain but this did not seem to
work, I got the same error!
Next I tried adding an "A" record to my domain for the WS, so I had
www.mydomain.com = IP of web server and added ws.mydomain.com = IP of the
server
providing the WS. But I still got the same error even though they are called
using the same domain name!
So what does IE check to establish if its cross domain before allowing the
call using XMLHttpRequest to a domain that is different from where the
calling page is hosted?
thanks

| window.open() problem in Firefox Rick Brandt 13:40:42 |
| | I am using window.open in an AJAX page and it works in both IE and FF but in the
latter the hourglass stays up and both the progress bar and the small animated
circle-of-dots graphic keep on running indefinitely in the new window.
I can press the STOP button to get them to stop, but I'm wondering if there is
something else I can do to get rid of this behavior. The page is most
definitely loading properly and completely.
If it matters what I am writing to the new document is an XML document after
being passed through an XSL sheet. Sometimes the XML doc is large enough to
fill several pages of the viewport, but often it is just a few lines and the
problem is the same regardless.
TIA

| ie javascript bug problem in this.options TKapler 11:58:37 |
| | i got this simmple function, It stays on onChange on select and on
change it hides all objects with ID equal to select name plus the
optionvalue. It works perfectly in Opera and FF, but IE crashes because
says that options object is null
the problem is in for (optionId in what.options)
It seems that IE does NOT return the list of options, but only some
other objects: language scrollheight, istextedit, currentstyle,
document, and onmouseup
Please can you help me how can I go throuth that cycle? I need to get
the values of all options in select. Thank you
function showHide (what) {
selectedId=what.options.selectedIndex;
selectedValue=what.options[selectedId].value;
selectedObject = document.getElementById(what.name+selectedValue);
selectedObject.className="";
for (optionId in what.options)
{
optionValue=what.options[optionId].value;
if (optionValue) {
optionObject = document.getElementById(what.name+optionValue);
if (optionId!=selectedId) {
optionObject.className="hidden";

| draw grid lines over an image in Javascript Guest 11:12:51 |
| | Hey there,
I have a large image in a browser window, and I would like a way to
overlay grid lines on top of the image, so a user can show the grid or
hide the grid lines. The grid would cover 100% of the image, and all I
would need is a set of horizontal and vertical lines over the image to
create a grid overlay
Is there a way I can leverage some functionality in Javascript to do
this? I can't use any server side 3rd party components, and I would
rather not do this using something on the server side like GDI+ through
ASP.NET.
Thanks,
Christian

| Modify Script to change background color based on Array Index DavidB 09:39:26 |
| | Greetings
I don't know if this is possible, but this group should be able to tell me.
I have a webpage with a changing message board (I understand the problems
with having changing text, but this was a nice victory over the demand for
a scrolling message). The messages are updates on community information.
What I would like to be able to do is have the background color (and
possibly font color) change based on the Array Index. For example, if the
pool is going to be closed for chemical treatment, I would like the display
to have a red background. If there is going to be street cleaning
requiring the removal of vehicles, I would like a yellow background. For
all other messages, a default blue background.
The code I am working with and abbreviated CSS & HTML are:
<script type="text/javascript">
var msgIX = 0;
var msgs = [
" Notices and Messages", \* RED *\
"Chemical Treatment August 21", \* RED *\
"Pool Closed", \* RED *\
" Notices and Messages", \* YELLOW *\
"Street Cleaning August 12 ", \* YELLOW *\
"Remove your Vehicles from the street ", \* YELLOW *\
" Notices and Messages", \* BLUE here down *\
"Family Movie Night is ",
"August 25 ",
" Notices and Messages",
"Pub Night and Quiz is ",
"October 14 or 21 (TBD) ",
" Notices and Messages",
"Pot Luck Dinner is ",
"November--Exact Date TBD ",
" Notices and Messages",];
function scrollMessages(milliseconds) {
window.setInterval ("displayMessage()", milliseconds);
}
function displayMessage() {
if (document.getElementById != null) {
var heading = document.getElementById("scrollme");
heading.firstChild.nodeValue = msgs[msgIX];
}else{
if(navigator.appName == "Microsoft Internet Explorer") {
var heading = document.all.item("scrollme");
heading.innerText = msgs[msgIX];
}
}
++msgIX;
msgIX %= msgs.length;
}
</script>
<style>
#noticebox {
padding:"2px";
border-width:"2px";
border-style:inset;
border-color:blue;
width:174px;
height:"42px";
z-index:30;
text-align:-moz-center;
text-align:center;
background-color:"#ceg";
left:0;
}
</style>
<body onload="scrollMessge(2000)">
<div id="noticebox">
<p class="mainbold" id="scrollme"> Notices and Messages</p>
</div>
Any assistance would appreciated--even if it entails telling me it cant be
done.
Thanks
DB.

However, When one of result returned false, that is rtn=false,

| Misleading cellIndex values with rowspan/colspan Matt Kruse 04:25:48 |
| | Using the .cellIndex property of a TH element to find out which table column
it is over can cause misleading results when the table has cells which have
rowspans or colspans greater than 1.
See example: http://www.javascripttoolbox.com/temp/table_cellindex.html
(code pasted below for reference)
This behaves according to specs and expectations, however the value of the
cellIndex property becomes less useful when using it to determine which
column to sort onclick, etc.
I plan to write some code to calculate the "actual" column index of each
cell in a <thead> of a table. But if anyone has already done this exercise,
please do share so I can perhaps use my time working on something else 
Thanks!
EXAMPLE CODE:
<html>
<head>
<title></title>
<script type="text/javascript">
window.onload = function() {
var ths = document.getElementsByTagName('TH');
for (var i=0; i<ths.length; i++) {
ths[i].innerHTML = ths[i].parentNode.rowIndex + "," + ths[i].cellIndex;
}
}
</script>
<style>
th {
vertical-align:top;
text-align:left;
width:50px;
}
</style>
</head>
<body>
<table border="1">
<thead>
<tr>
<th rowspan="2"> </th>
<th> </th>
<th> </th>
<th> </th>
<th> </th>
</tr>
<tr>
<th colspan="2"> </th>
<th rowspan="2"> </th>
<th> </th>
</tr>
<tr>
<th colspan="2"> </th>
<th> </th>
<th> </th>
</tr>
</thead>
</table>
</body>

| Stopping/starting WMA Andrew Poulos 03:08:05 |
| | I'm using Windows Media Audio, via a WAX file, and I have some custom
controls to start and stop the audio. While it works in IE, FF gives an
error. The HTML looks like this:
<object id='obj' type='audio/x-ms-wax'
style='position:absolute; left:0px; top:0px;'
classid='CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95'
codeBase='http://activex... blah
width='100' height='100'>
<param name='FileName' value='wma_sample.wax'>
<param name='AutoStart' value='0'>
<embed id='objff' type='audio/x-ms-wax'
src='wma_sample.wax' autostart='0' width='100' height='100'></embed>
</object>
and the relevant FF JavaScript look like this:
if (typeof document.getElementById('objff').Play != "undefined") {
document.getElementById('objff').Play();
} else {
alert("An error occurred and the audio could not be played.");
}
If I change the type and the sample to an MP3 file then the custom
controls work in FF. Is there a way to get FF to control WMA?

| Any way to override submit behavior for input img? Christopher.Secord@Gmail.Com 00:28:56 |
| | Normally, a button like <input type="image"> is also a submit button.
Is there any way to override that so that it has an onclick event but
does not submit the form?
For what I'm trying to do, I cannot use an <img> element with onclick.
I have to use a form element (and I'd rather have an image than a
button)
Thanks in advance for any insight.

| Public static method accessing private method Guest 22:00:52 |
| | Hi there,
I'm trying to do something, but I don't know if it's possible.
Basically, I want to have a public static class method that could
access a private object's method. I would like to be able to do :
Class.method(InstanceOfClass);
The method would then access a private function from Class by doing
something like
function method(param) {
param.privateMethodOfClass();
}
I've done a lot research and experimentations but just can't come up
with a solution... I don't even know if what I'm trying to do is
possible.
Any help would be appreciated.
Thanks.
