First of all, you need to verify that your code is not the problem.

Things that might cause your code to be the problem:

1) Browser specific code. If you're doing any form of browser or feature 
sniffing in your code, then you need to check that the result of that 
browser or feature sniffing is valid.

2) Any errors in markup that might affect the dom that it presents to the 
javascript, especially if the javascript is then making assumptions about 
the dom element tree that are invalid due to an inconsistency between 
(for example) the declared dtd and the actual markup.

3) A change in a non ratified "standard" such as html 5 that means that 
something that used to work doesn't any more.

I doubt that a chrome update would break previously working javascript 
unless that javascript and / or the dom it was manipulating were in some 
way flaky to begin with, and it's very unlikely that it would happen in a 
manner that only broke your system (I haven't noticed widespread 
complaints of broken chrome javascript, nothing seems to have been 
prominent on eg slashdot) unless the underlying issue was with your 
system.

So this brings us back to:

Please provide a url for a publicly accessible web page that contains the 
minimal html and javascript required to demonstrate the problem.
