[ubuntu-uk] Testing websites

[Mark Harrison]

Not particularly Ubuntu related, but a couple of comments for web 
developers:

1: I've found the "Firebug" plugin for Firefox is a very, very good tool 
for testing for potential JavaScript errors.

2: There are some standard JavaScript objects that exist as part of the 
DOM in some browsers, but not in others. You can't rely on JavaScript 
version checking OR Browser version checking to identify them - it's 
better practice to wrapper them in an "if object exists" loop.
