Huh? JDAMs are GPS guided bombs. You enter in the location you want to hit and it is guided there. You can't hit a moving target (like with a laser guided bomb) unless you get lucky enough to have it driving over the target location at exactly the right time or you find some way of constantly updating the target location on the bomb after it has been let loose.
We now have laser-guided JDAMS.
New in 2008, IIRC.

“Huh? JDAMs are GPS guided bombs.”
Yep, they’re called the GBU-54
They come with an optional laser seeker package to give the ability to strike a wider array of targets to include moving ones.
