Hi, ya'll:

I've got a situation I can't fathom.

I have a simple js function:

var region = new Array();
var region = new Array();
region["11"]="the upper-outer quadrant";
region["13"]="the upper-inner quadrant";
.

function decodeRegion(score,target1) {
if (score > 100) {score -= 100;}
mV = score.toString(10);
document.getElementById(target1).innerHTML = region[mV];
}

In a plain vanilla HTML page, I call the above with either an
onLoad="decodeRegion(11,'insert_here') or with a checkbox using the same
syntax, but with an onClick event, e.g., as follows:

<input type=checkbox onClick="decodeRegion(11,'insert_here');">ClickMe
<span id="insert_here"></span>.

Either the onLoad or onClick events work fine; however, when I create then
HTML page wirth Perl, upon calling exactly the same function (cut and
paste and adding appropriate escapes ''), I get an error. Using Opera,
the js console error displayed is:

ReferenceError message: Statement on line 1: Reference to undefined
variable: decodeRegion.

In IE, I get 'object expected' error.

What is happening, and what can I do to resolve the issue?

TIA,

Follow up:

I should have mentioned that I'm using a linked external javascript file.

I also just discovered if I put the function and array on the HTML page
generated by my Perl script, it works. WT...?

Does your Perl script use:

use strict;
use warnings;

if not, add them.

Also, if you output several lines of something, use:

print <<'EOT';
.....
.....
.....
.....
EOT

with single qoutes around EOT you don't have to escape a thing.

If you want string interpolation to work, use "" around EOT, e.g.

my $msg = 'hello, world!';

print <<"EOT";
....
....
$msg
....
EOT


Make sure there is *nothing* after the ending EOT (which is just a random
name, you can probably think up a better end of text marker), just a
return.

Common mistakes: - white space other then end of line after EOT
- a ; after EOT

(the ending one I mean).

I'm not. Short lines.

Everything looks fine, codewise. Using exactly the same syntax, but
including the js and array on the generated page works fine. It's only
when I link to an external js file do I run into the problem. So...I now
have the js on the created page.

Thanks.

Odd, odd. I thought that somehow you got Perl to interpolate something
that it shouldn't.

What happens if you compare the HTML source between the two pages?

The HTML page that works is different than the one generated by Perl. I'll
try it today. Thanks for the idea.

Problem solved. There was another script in the linked file that was
problematic. Had nothing to do with what I was trying to do, but it killed
all subsequent function calls. My app comprises several Perl-generated
HTML pages. The errant function is used on an early page and it's error
wasn't noted.

Thanks for your help.
