How do java consoles in head tags affect your ranking?

do exit consoles and onUnload in body tag affect in any way?

I wonder whether window blur, exitcnsl()and other types of exit consoles might get you in troble or lower your ranking?

I have seen no evidence that using a javascript event handler will hurt your rankings.

The way I usually look at things like that - if Major websites (news and authority sites) use them and get their PR9's, then I doubt Google is looking at that as a problem.
