Javascript void and PageRank

[LCNetwork]

Do javascript void links to on-page elements (not to a new page) consume PageRank?

I'm paring down links on a client's homepage, and we have javascript void links (wrapped in <a href="">) that load videos, elements of a slider, etc. on the page itself.</a>

<a href="">Basically, if I have a bunch of these, is it going to weaken the power of the other links on the page?</a>
