How to write to Firefox's JavaScript console?

kj

How can a script send (non-fatal) warnings and other such messages
to Firefox's JavaScript console?

Thanks!

I suggest you install the Firebug extension for Firefox:
https://addons.mozilla.org/firefox/1843/

Once you install, the Firefox javascript console replaces the built-in
javascript console. Then you can write to the Firebug console using
this syntax:
console.debug(" hello world");
or to print the values of variables foo, bar and baz, you can use
printf syntax:
console.debug(" First value is %s, second is %
s and the last is %s", foo, bar, baz);

The documentation for Firebug can be found here:
http://www.getfirebug.com/docs.html

Firebug has a rich debugging syntax, but also a JavaScript debugger(!)
and a DOM inspector.
I've found it to be a wildly useful development tool.

If you're interested in all that as well, here are a couple of links:

Better yet, show warning, errors, debugging info, value of variables,
whatever, right on the page you're debugging, with fvlogger:

(Sorry if this is a repost...my newsreader keeps crashing on the posting--I don't know if the message going out or not) For some reason this javascript just won't work in Firefox. It works fine in IE, though. I know, IE is a bit more permissive than IE, and sometimes lets errors work when they shouldn't. But from what I can see, I just don't see what's wrong.

I have a web application that uses xsl and javascript which runs smoothly on IE. Recently i decided to try it on FireFox 1.0 .

I have given a code of a xsl page. Can someone point what possibly could be the problem. <?xml version="1.0"...

I came across a third party script I want to learn how to configure as well as learn more dhtml in the doing. I'm not much of a JS guy yet but I'm working on it. This script works fine in IE6 but is a dead fish in FireFox. There is no support offered on the site where it came from. I'd really appreciate help with this as it will not only to get it working but to learn how it all works so I can add it to my repertoire. Thanks!
