Firefox yielding unexpected results with document.scripts

I've been encountering a puzzling issue trying to debug a script that won't work in Firefox, even though it runs smoothly in other programs. In the code snippet from chirp.js, there's a line that reads:

script = document.scripts[document.scripts.length-1]

This line is throwing an error saying: document.scripts is undefined

When I check document.scripts in the Firebug console, it comes up as undefined, as expected. I checked Mozilla's documentation and found information on how to access it. Surprisingly, when I tried the same thing in the Chrome console, it displayed a list of loaded scripts.

This issue isn't limited to my own computer; it's also happening on my client's machine. Could this be related to a plugin or addon problem?

The same error occurs on the chirp project page as well.

Has anyone else encountered this issue before? I tried searching online, but couldn't find any relevant solutions among the pages of results about the document.scripts object.

Answer №1

There seems to be an issue here that needs addressing. Simply typing out the code below will result in a length of 1:

<!DOCTYPE html>
<html>
<head>
</head>
<body>
<script>alert(document.scripts.length);</script>
</body>
</html>

Give it a try on your Firefox browser. If it functions correctly, then there may be another underlying problem.

Disclaimer: This was tested on the most recent version of Firefox for Mac as of January 23, 2013.
