CSS link query

Hello all

I'm putting together a banner ad.
I'm creating a bit of simple animation and there is a link for the user to click to go to an external site.

Now I just usually insert a href link.

But now the client as asked I just include a standard click tag as the URLs will be added at a later stage once they go to the client. It needs to be built as a https.
The reference I have been given is 'on(release):{ getURL(_root.clickTag,”_blank”); }

Sorry but this means nothing to me. I'm presuming this is jQuery??
Not sure how I use this?? I sense this is pretty simple, but I am new to this area.

Can anyone help?? Would be so grateful.

Thanks

Sean
