tedster is wrong. My testing shows that Google currently ignores <a href="#" onclick="fn()"> links and <span onclick="fn()"> psuedo links. They DO NOT count towards the number of links in the page in the denominator of the percentage of pagerank passed to other links.
Google may however update their algorithms at any time. In addition, it looks spammy. You are trying to hide something from the algorithm. I'm not confident that such tricks would pass a manual review by a Google engineer.
