JavaScript In HTML: Unexpected Outputs
Jul 23, 2005
I'm learning/experimenting with some simple JS/html markup, running
an apache daemon and mozilla firefox browser in RH 9.
Let's say I run the following markup with one or more of lines 6-10
commented out:
1 <html>
2 <head>
3 <script type="text/javascript">
4 function showinfo()
5 {
6 width = window.screen.availWidth;
7 document.write("<br>screen width=
");
8 document.write(width);
9 document.write("<br>Date: ");
10 document.write(Date());
11 }
12 </script>
13 </head>
14 <body onload="showinfo()">
15 <p>
My question: is there a simple explanation to account for the 'unexpected'
behaviours below (Runs 1, 3, 5)?
Run 1: nothing in 6-10 commented out; output (expected more):
screen width=
Run 2: line 7 commented out; output (as expected):
1024
Date: Wed Apr 14 2004 20:55:58 GMT-0400 (EDT)
Run 3: lines 7, 9, 10 commented out; output (as expected, but unfinished loading):
1024
[ongoing hourglass indicating loading in progress]
Run 4: lines 7, 10 commented out; output (as expected):
1024
Run 5: lines 7-9 commented out; output (as expected, but unfished loading):
Date: Wed Apr 14 2004 22:46:49 GMT-0400 (EDT)

I'm having a problem showing the output of this code in the textfield.
<html>
<head>
<script language="JavaScript">
<!--
var url = document.URL;
-->
</script>
</head>
<body>
<textarea style="overflow: auto;" rows="1" cols="70" wrap="off" readonly>
<script language="JavaScript">document.write(url);</script>
</textarea>
<br><br>
<script language="JavaScript">document.write(url);</script>
</body>
</html>
The output isn't showing the browsers current URL which is the desired effect, instead it is only showing the raw JavaScript code.

anybody knows a way to buffer the outputs from document.write?
We want to reload the advertising banners on the page when an user browses trough the pictures in our AJAX-Gallery, but the scripts from our advertising partners uses document.write, so we can't call the addBanner() function from inside the gallery-script.

I have resorted to using a forum after 2 days of head scratching. What I need is some script to monitor the output of a php file that outputs "yes" or "no" depending on weather it is your turn in a multiplayer game.I would like it to just check every few seconds (in order to not crash the server) if it has changed. While the PHP file is showing "yes" I want it to show some buttons to make a move and when it is showing "no" for it to just say something like "enemy's turn". I hear that this kind of thing could be achieved with jQuery and AJAX but I have never used JavaScriptI already feel like I'm making a big ask but if you don't mind I would also like a way of submitting your move to a php file to make the move (submitting something to MySql)

I need to use string split to get two outputs for an email address, one output the user name and the second to be the domain name, for example xxxxx@xxxx.com needs to be seperated at the @ symbol so one output would be the xxxx and the second would be xxxx.com. How to get the second output right.
<html> <body>
<script type="text/javascript">
function convertEmail(inEmail) {
var atPosition;
var stringLength;
var username;
var domain;
username = inEmail.indexOf("@");
stringLength = inEmail.length;
domain = inEmail.substr(0,atPosition);
username = inEmail.substr(atPosition+1, stringLength);
domain = inEmail.substr(atPosition+1, stringLength);
return username ;
return domain;
}emailIn = prompt("Enter username@domain", "Doe@Jane");
alert (convert (inEmail))
alert (convert (inEmail))
</script></body></html>

How would you go about writing a function that returns a string that outputs a branched bulleted list using <ul> and <li> tags of all the html elements in a page? The html elements don't all have id's or names, so I cannot reference them directly. I would like to do it recursively so that I can grab all the elements, not just those two or three levels deep.

I'm working on some code and am running into brick walls. I'm trying
to write out Javascript with Javascript and I've read the clj Meta FAQ
and didn't see the answer, read many similar posts (with no luck
though), and searched through the IRT.ORG Faqs
(www.irt.org/script/script.htm).
The Javascript is designed to open an popup window and then inside that
window call another script which will resize that window. There may be
another way around this but the reason I tried this approach initially
was that I wanted to call the onload handler in the popup window to
resize the image only after the image had completely loaded. I've had
some code in the primary Javascript file (showimage.js) before that
works if the image has been cached but on the first load, it doesn't
resize properly which tells me it is probably because it is trying to
resize the window based on the image size but it isn't completely known
at that point. So I removed that code and tried placing the resizing
code in the second Javascript file (resizewindow.js). BTW I've tried
other code to open a popup image and automatically size it ie Q1443 at
irt.org but that doesn't do exactly what we need.
Even if there is another way to do this with one file, I still want to
figure out why this isn't working in case I run into it in the future.
I thought what I would need to do to use document.writeln to write
Javascript would be to escape any special characters and to break
apart the script tag ie
document.writeln('</SCRIPT>');
would become
document.writeln('</SCR' + 'IPT>');
I have a HTML page and 2 Javascript files. All files are in the same
directory and have permissions set correctly.
Here are the 3 files (keep in mind wordwrap has jacked up the
formatting):
index.html
----------
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Test</title>
<SCRIPT type="text/javascript" LANGUAGE="JavaScript1.1"
SRC="showimage.js">
</SCRIPT>
</head>
<body>
Click the house<BR>
<A ONCLICK="newWindow1('house1.jpg','Nice House')"><IMG
SRC="house1thumb.jpg"></A>
</body>
</html>
showimage.js
------------
function newWindow1(pic,sitename)
{
picWindow=window.open('','','width=25,height=25,sc rollbars=1,resizable=1');
picWindow.document.writeln('<html> <head>');
picWindow.document.writeln('<SCR' + 'IPT type="text/javascript"
LANGUAGE="JavaScript1.1" SRC="resizewindow.js"></SCR' + 'IPT>');
picWindow.document.writeln('</head>');
picWindow.document.writeln('<body onload="resizewindow();">');
picWindow.document.writeln('<img src=' + pic + '>');
picWindow.document.writeln('</body> </html>');
picWindow.document.close();
}
resizewindow.js
---------------
function resizewindow()
{
// Do resizing here.
// Right now this isn't being executed
alert("resizing window");
}
Can anyone provide some pointers as to why this javascript is failing?
I'm using IE6 on Win2k and when I click on the image to open the popup
window, it does open the window but it is white with no content and the
system immediately goes from about 4% CPU usage to 100% and
consistently stays there until I kill that window with the task
manager.

Considering the following list how do I get a reference to the ul just below
the li with id products? nextSibling gives me a reference to the #text# node
inside the li tag?
<ul>
<li id="products">products</li>
<ul>
<li id="child">child</li>
<li id="chair">chair</li>
</ul>
</ul>
I want to create several functions to add or remove items from the list.

I am having a problem with internet explorer 7. I am working on a site that maps google maps to show .gpx files, and it is working fine in IE8, firefox (v2 and 3) and safari. However in IE 7 i am getting the following error when running the following line
Code JavaScript:
$(document).ready(function() { initialize(); $("#player_controls a img").tooltip(); });
Line: 45
Error: Expected Identifier, string or number;
The funny thing is that initialize is a clearly and previously defined function, I had some problems before with IE due to variables being out of scope, so I am afraid this may be something related, but I am not very familiar with IE inner workings so,

In the below, I would expect this to return the number of milliseconds since the epoch. Instead, it's generating a massive negative number. I presume I've gone wrong with the set[Blah] methods.
javascript Code:
var date_text = '2009-03-06 12:00:00';
var d_tried = new Date();
d_tried.setYear(parseInt(date_text.substr(0,3)));
d_tried.setMonth(parseInt(date_text.substr(5,6)));
d_tried.setDate(parseInt(date_text.substr(8,9)));

I am having some troubles with arrays. I am using Chrome 12 beta.
Here is a brief version of the code I am having trouble with
I do not want to use "array[0][1][n]" because my array has too many items to do that and it is just plain annoying to change the numbers that way.
I get an error on the "var buffers[0][1]=[" line saying: "Uncaught SyntaxError: Unexpected token ["

This error ONLY occurs in IE. "Unexpected call to method or property access."
I pinpointed it to this line:
o.appendChild(e);
The full function is:
function aO(d, t, src, p, id ){
alert('aO has begun.');
var o, e, i;
if (!ie){ o = cE('object');o.data = src; }
else { o = cE('embed');o.src = src; } .....

I am experiencing unexpected behavior using $(document).ready() on a page where I inject jQuery after the page has loaded and then attach listeners to the ready event. The ready() event is never called using Firefox and Safari however it is called using IE. Is this a jQuery bug? Is it working as designed?

I have an XML file that among other things has the following node.
As you can see it contains HTML tags.
<description lang="en">
<![CDATA[
<div class="descrBoxRight" style=" top:250; left:200">
ENGLISH <b>ENGLISH</bENGLISH ENGLISH
</div>
]]>
</description>
With javascript, in Mozilla, I easily retrieve the content of the
XML "description" tag using the following line of code
var myStuff = myDescrNode.textContent;
However, in IE (6.0)
var myHTML = myDescrNode.textContent;
and
var myHTML = myDescrNode.innerText;
do not work, resulting in myHTML being undefined.
Alternative solutions? Should I remove the CDATA tag
and use a completely different method?

On the time sheet page i have created a years worth of entries in the
database for a user so that they may create entries ahead of time(for
holidays etc.).
My problem is that when i load the page, i display the current month
for that user and it displays:
Date Month Day TimeInMorning TimeIn Evening etc..
What i would like is that a user may update any field and click on a
save button which will update the field(s) that they have changed. I
ahve attempted in javascript to do this but i am failing.
