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(/</g, '<');
content=content.replace(/>/g, '>');
Element.update('template',content);
}
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?

I have a custom object named #cdata-section, however I am unable to
access this object and get a run time "Illegal Character" javascript
error. my object looks like this:
data.news.story[i].body.#cdata-section
The pound sign is causing problems. How can I use this object in my
javascript source? Right now I'm trying something like this to escape
the pound sign:
summaryNode.appendChild(document.createTextNode(da ta.news.story[i].body.u0023cdata-section));
however, that doesn't work, any ideas?

I've been looking at this for a while now and I just can't get my head around it. What i need to do is put together a program which allows the user to type in a sequence of letters and then tells the user how many times they have included the letter 'a' in their sequence. So far i have put this together but the output is totally wrong at the moment and it often either just says 1 or 4. Code:

I have built a page on a recruitment website which allows users to upload their CV via ASPUpload i.e a browse button. However I want to limit the file type to just MS Word documents as I do want them uploading large PowerPoint files etc. My idea is to have some javascript which evaluates the last 4 characters of the file name to ensure it is .doc
So if they try to upload anything other than a .doc file a dialogue box will appear stating that they must only upload MS Word Document (when they click the ‘Upload CV’ button).
Does anyone know how I can evaluate the last 4 characters of the file name? Once the user has browsed to their CV on their PC the path & file name will appear in a text field called ‘CV’.

My question is:
I'm adding character 253 to a javascript string this way:
var str = ''
str += 'a'
str += unescape('%FD');
str += 'b'
Is there another way to do this. Is there a function like: str += char(253)?

Initially the form is loaded using ASP and HTML and the ü codes
display the characters correctly. I have the values stored in a
javascript array so that I can more easily and dynamically change the
state/region dropdown when the country changes. However, when my
javascript code tries to add the new option and print out new region
the literal value such as "Würrtemberg" is displayed instead of
the special character.
Can this be done in javascript?

i have checkbox to call function
<INPUT TYPE = "checkbox" NAME = "AttributeValue[1]" VALUE = "Yes"
The function itself has this:
if (form.AttributeValue[1].checked) {
(more script) }
That doesn't work because I believe it is interpreting the [ ] characters
as representing array (I think).
How is syntax for AttributeValue[1] as literal value in function?
Does this make sense?

I'm trying to write a function that takes a word and adds a space between each letter e.g space becomes s p a c e. I have written below but when I call the function it says the argument is not defined.
Code:
function insertSpaces(string){
var currentCharacter;
var resultString;
resultString = ''
//a line to loop through each charcther in the string agument
for (var position = 0; position < string.length; position =
position + 1){
// set current characther as the first charcter in the string and add a space
currentCharacter = (string.charAt(position) + ' ')
//store the currentcharcter and add followng characthers
resultString = currentCharacter + resultString
} return resultString
}

I'm just wandering, how can you stop the replace() function from replacing characters inside a word, such as, if I try to replace 'x' with 'and', then my string would go from 'example, x' to 'eandample, and'.

I am having problems with the code below (obviously) coming up with illegal character for various characters within the field name
which is: S_Gift Finder1_0
I have tried various ways of escaping the characters but to no avail.
I am unable to change the name of the field as it it comes from an external off-the-shelf package. Code ....

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.

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:
<html>
<head>
<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;
}
</script>
<frameset cols="100px,*" name="framed">
<frame src="lframe.htm" name="frameMenu">
<frame src="mframe.htm" name="content">
</frameset>
</head>
<body>
</body></html>
Come someone let me know what I'm doing wrong here?

I have three different web pages with different domains, and I want to
show some pages of one of the webs in the others.
I use an iframe for this and it shows it good until I have to call a

So, the cuestion is:
Is there some way to call the javascript function of the iframe from
the parent page?

I have a select dropdown and 5 text fields. based on the option
selected (which are the units - cm/mm/inches/ft/yard etc), i change
the values in the text fields using javascript to the corresponding
units.
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
illegal.
I suspect that the javascript function is being called even before the
earlier execution has not terminated. I tried using a global variable and using it as a lock, but still no success.

I am coding an AJAX DHTML whatever application and I was fed up with
always typing a lot of appendChild() functions.
I created a custom one called append_children() and wanted to share it
if anyone need such a function.
function append_children() {
var a = append_children.arguments;
for ( var i = a.length - 1; i > 0 ; i-- ) {
try {
a[i-1].appendChild(a[i]);
} catch(e) {
for ( var j = 0; j < a[i].length; j++ ) {
append_children(a[i-1], a[i][j]);
}}}}
