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

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


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

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<SCRIPT type="text/javascript" LANGUAGE="JavaScript1.1"

Click the house<BR>
<A ONCLICK="newWindow1('house1.jpg','Nice House')"><IMG

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('<body onload="resizewindow();">');
picWindow.document.writeln('<img src=' + pic + '>');
picWindow.document.writeln('</body> </html>');

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

Javascript Function Has No Properties In Javascript Console

May 25, 2005

I'm getting errors in Firefox everytime I try to run this frame resize code, but it works fine in IE. I can't seem to figure out what the problem is with it.

The error is: Error: theFrame has no properties
Line: 8

The line that the javascript console is showing an error for is in italics.

code from page:

<script type="text/javascript">
var defaultCols="100px,*";
var hiddenCols="0px,*";
function ShowHideMenu(){
theFrame = document.getElementById("framed");
if(theFrame.cols == defaultCols) theFrame.cols=hiddenCols;
else theFrame.cols=defaultCols;
<frameset cols="100px,*" name="framed">
<frame src="lframe.htm" name="frameMenu">
<frame src="mframe.htm" name="content">

Come someone let me know what I'm doing wrong here?

Too Many Characters In A JavaScript Function?

Nov 19, 2007

In IE, it looks like you can have to many characters in a javascript function.

The content of an entire html page is put into this function...

function updateTemplate(content) {
content=content.replace(/'/g, ''');
content=content.replace(/"/g, '"');
content=content.replace(/&lt;/g, '<');
content=content.replace(/&gt;/g, '>');
it seems to cut off the content after about 2060 characters. is that an IE thing or is there something wrong with my code. FF does it fine...

If it is an IE thing, is there anyway around it?

DOM Javascript - Imbed Javascript In Dynamically Added Row

Jul 23, 2005

Attached is a simple HTML file that adds and delete rows. In the add
row function I set an attribute "onClick" this triggers the
testMessage() function. When I try this in Firefox it works just fine
however on IE it just refuses to work.

What is interseting is the ROW that already exists has a similar
'onClick' event which works when the page is loaded, but subsequent
"row" additions to the table to not work in IE. Code:

'Javascript Anthology' Or 'Professional Javascript For Web Developers'?

Mar 30, 2006

I'm already past the basics of Javascript, and i need something that takes me to the other level and teaches me the new technologies and cool stuff (drag&drop, AJAX, OOP in javascript, maybe XUL...etc). So far i found these two books:

1. Sitepoint's "The JavaScript Anthology: 101 Essential Tips, Tricks & Hacks".
2. Worx's "Professional JavaScript for Web Developers (Wrox Professional Guides)"

Both seems to cover very insteresting topics, but i can only buy one of them. So which one do you suggest?

and by the way, i've read the sample chapter 5 of Sitepoint's book, and it seems like the author(s) just put the solutions/codes there and let you figure them out on your own. Is this how the rest of the chapters are?

Prevent A Javascript Function From Executing Twice

I have a select dropdown and 5 text fields. based on the option

the values in the text fields using javascript to the corresponding

my problem is that when the options are selected very quickly(for eg
using the keyboard's up/down keys) then quickly, the text field values
lose their connection with the select box and the values become

earlier execution has not terminated. I tried using a global variable and using it as a lock, but still no success.

Port Of PHP's Date() Function To Javascript

Dec 7, 2002

Okay, this an attempt to port PHP's date() function as much as possible to JavaScript. Could use some refactoring though. Any critique, comments, appraisal and any other opinion is very welcome. Feel free to discuss and also take a look at beetles code here: http://www.codingforums.com/showthread.php?s=&threadid=11069

Oh, and the date() function is described here: http://www.php.net/manual/en/function.date.php
