Dynamically Writing Html/javascript From A Javascript Function

Jul 23, 2005

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.

Writing Out To A Text File With Javascript

Jul 23, 2005

What I want to do is create a HTML form that allows the user to enter data
into about 10 fields, and then based on the entered data, writes out data
strings to a text file. I am attempting to create a form for entering
simple rectangle CAD data via a HTML form, which will be written to a text
file, and then imported into a CAD program.

The form would contain prompt boxes for things like length, width, radius
size, step/repeat, etc. When the user hits the "SUBMIT" button, the data
strings would be written out to the filename the user specified. Below is
an example of data strings to be ouputted. Variables are &L, &W, &R,
&STEPX, &STEPY, &XN, &YN.

Writing A PHP And Javascript Generated Page To A PHP Variable...

Sep 3, 2006

I have a form that posts data to a PHP mailer page I have created. When
it goes to the PHP mailer page it reads some of the data and modifies
the page accordingly using Javascript (hiding certain divs, etc...). My
goal, is to take all this data after it has been processed by
Javascript and send it through my PHP mailer as it is currently
formatted.

If it helps any, the track I am on right now involves encapsulating the
Javascript processed block in a div. I am then trying to take the
..innerHTML data from that div and store it in the PHP $message variable
for my mailer. This won't work because PHP is server side. So, I moved
on to generate some Javascript code (with PHP) that sends all that
messy HTML data that its processed through a URL variable to then be
read by PHP. This doesn't really accomplish what I want as it cuts off
about a quarter of the way through my data......

Any ideas??

One thing I thought of but don't know how to do or whether it's even
possible is using PHP to view the source of the current page and store
that as the HTML to be e-mailed. Or, is it possible to do something
similar to .innerHTML with PHP?

Writing To Firefox/Mozilla Javascript Console

Apr 13, 2005

Firefox has a Javascript Console that has 3 panels besides "All" and "Clear": "Errors", "Warnings", "Message".

Does anyone know a way to log a message in the Message panel with JavaScript? That would really help debugging. I know there's a way involving XPCOM, but that only works with "trusted" scripts, and scripts loaded thru html aren't trusted.

Writing To Head Using Js And Dom

May 10, 2006

i've been reading up on access to the dom via js (i'm new to this dom
stuff)

i understand tutorials and info such as
http://developer.mozilla.org/en/doc...t.createElement

my problem: i'd like js to create the code for a stylesheet in the head
of the docuement!

i'm not sure how do do this (or if it can be done)

can i create the following...

<link rel="stylesheet" type="text/css"
href="mystyle.css" />

OR

<style type="text/css">
hr {color: sienna}
p {margin-left: 20px}
body {background-image: url("images/back40.gif")}
</style>

using the dom or anything else in js alone?...or am i fighting a losing
battle.

(what i really want at the end of the day is to detect the browser and
use a css file according to that file, either with js or php)...

Writing To An IFrame

Jul 20, 2005

I have an existing page that dynamically creates data in a popup
window. I am trying to change it to use an iFrame. Is the following
code valid:

The iFrame is as follows
<iframe src="theframe.html" name="theframe"></iframe>
"theframe.html" is an existing file initially with instructions.

In a script I do
thewindow=window.open("","theframe");
thewindow.document.open();
thewindow.document.write("Some Requested Data");
thewindow.document.close();

This is done multiple times depending on what the user requests each
time. Sometimes this works and sometimes it doesn't. I'm probably doing
someing very wrong but I don't know where to look for reference.

I'm not really opening a window so there must be another way to do it.

What is the best way to write to an iFrame or should I not even try?
Code:

Writing Tic-Tac-Toe Program?

I'm trying to write a Tic-Tac-Toe program in JavaScript. I have an array containing the state of the grid. For some reason when I update the "O" for the computer's move, it doesn't show this in the updated grid. I don't understand why.[URL].. I'm brand new to JavaScript, and sometimes I accidentally use syntax from C++ or PHP when writing, so it could be something as simple as that. I just can't figure it out.

Jul 23, 2005

I trying to but buttons for the users to write special characters to a text area in a form by clicking in a button.

Clicking on any button doesn't do anything but if I put just one button it works, can anyone suggest what did I do wrong?

Writing A ToFixed Function

Jul 20, 2007

I'm not that familiar with javascript, and I am trying to write a
toFixed function.

The function takes two arguments, the number and the number of decimal
places we're interested in.

If the number of decimal places is negative, it's interpreted as the
number of significant digits.

Thus:

toFix(12345.6789,2) -12345.67
toFix(12345.6789,0) -12345
toFix(12345.6789,-2) -12000

I've hacked up a solution that so far works on all tested browsers for
the first 2 cases.

It's the last one I'm having trouble with... How do I get only the
significant digits?

It has to work for all of the following cases:
toFix(12345.6789,-2) -12000
toFix(12345.6789,-5) -12345
toFix(12345.6789,-7) -12345.67
