As you may know Google may or may not(yet) crawl javascript code and respectfully get more links from/to the site from such code.

Many good SEOs like the Hijax’s site or the Google Webmaster Blog suggests to have html links as well as javascript built links so the spider can crawl the “old fashioned” html “hard” links with no problems and still people to have javascript code on the site such as Ajax and other dynamic content.

But this still alerts me with the question: “What will happen when Google and the other search engines start to crawl javascript code and find the same links as the html ones that point to the same pages but from (if may say it that way) different sources?” .

At this moment Google has its algorithms to get the most appropriate page from duplicating links with session id in them or links with random placed variables like: ?var=something&var2=something2 <–> ?var2=something2&var=something.

What about JavaScript?
