Indexing for discovery is one thing. Using the data to pass PageRank or influence ranking is something else.

I got a very different impression after listening to this Matt Cutts video: [youtube.com...]

That still falls short of saying JS links flow PR. Depends on the context in which it was said. It could only be a reference to stopping the JS links from being used for discovery.
I haven't listened to that but will later tonight after I've finished with my evening parental duties.

This statement was made as part of a big post made in May 2009 on SearchEngineLand (not linked to as not sure if it would be allowed) following the Google May 2009 I/O conference.
The way the article reads to me is that she's quoting an announcement made at the conference but I can't find anything in writing from Google on the subject.

I've read that essay [searchengineland.com] from last year and it's not clear. Here is the relevant quote from a Googler (with emphasis added):
|Our onclick processing is becoming more widespread, but keep in mind it’s still an area where we’re constantly improving. We already detect many ads generated by onclick events. |
To prevent PR [PageRank] flow, it remains a good practice to do things like have the onclick-generated links in an area that’s blocked from robots, or to use a url redirector that’s robots.txt disallow’d. Penalties for spam techniques have been and will continue to be enforced, but as you know, we work extremely hard to minimize false positives.

In this situation pop.htm was indexed, however anchor text (a unique two word gibberish phrase) was not passed.
As far as I remember onClick events in img tags do pass anchor text from the img alt tag. I've set up a test to check this.
If Google indexes content at the end of a link that cannot be reached any other way I'd say that means that PR is being passed. However when they announced in 2008 that they were crawling GET forms and indexing content discovered that way they mentioned that pages discovered wouldn't be seen to be part of a site's index allocation - which is based on PR.

Re: that article, this was the bit I was referring to:
Googlebot is now able to construct much of the page and can access the onClick event contained in most tags. For now, if the onClick event calls a function that then constructs the URL, Googlebot can only interpret it if the function is part of the page (rather than in an external script).
Some examples of code that Googlebot can now execute include:
<tr onclick="myfunction('index.html')"><a href="#" monclick="myfunction()">new page</a>
These links pass both anchor text and PageRank.
It's not explicitly stated, but that looks to me like a report of a statement given at the conference by a Googler.

You're right, but it's not a direct quote. The statement itself looks like it's coming from Vanessa Fox herself, not a quote attributed to a specific Googler.
I searched all the Google blogs for a statement, as well as on the web for a direct quote of a Googler that confirms the year old statement by Vanessa Fox but there is nothing there.
I tried to find evidence to substantiate this rumor but I can't find anything.

Sorting out anchor text, trust and other possible link juice factors is more complex. I can't confirm or refute any of that.
Along these lines, I also had an emergency call last year from someone whose website had a penalty. Their widely distributed widget included an embedded js link to their website. When they removed that link from the widget and requested reconsideration, their rankings returned.
Just a couple of data points there. I can't point to anything Google officially published on the web to firm it up any further.

Hey thanks Ted. There is informal confirmation that JS passes PR.

Here's something relevant on video from Matt Cutts [youtube.com].

I'll let the experiment go a while longer just to make sure, but it seems if JS if followed it is the exception, not the norm.

This statement is inaccurate. Google crawls nofollow links and finds content on the other side, but the link value itself is not added to the link graph and does not impact the link profile of the destination page, so assuming that because Google can find and even index content via a link does not conclude that the link passes pagerank.

You're right, I didn't mean that to be such an assertion. I sort of qualified it with the next sentence.
"However when they announced in 2008 that they were crawling GET forms and indexing content discovered that way they mentioned that pages discovered wouldn't be seen to be part of a site's index allocation - which is based on PR."
