Getting current iframe URL problem

Hi I am having a problem getting current URL of an iframe on one of my pages, the only thing I have tried that remotely works is document.getElementById("frame_id").src << and with this it only returns the original domain of the frame, not the current. I have also tried all of the following and none have even come close to working:
window.frames["frame_name"].location.href
window.frames["frame_name"].location
window.frames["frame_name"].src

If you know any solution I would greatly appreciate your help, thanks.

I have a correction to make, when I use:
window.frames["frame_name"].location.href
it returns "about:blank" no matter what URL is open, including google and yahoo. What should I do?????

Thanks.

Maybe
window.frames["frame_name"].src

naa man I had already tried that b4 and it didn't work. I think I have tried pretty much everything, I don't know if this is even possible, the only lead I have is window.frames["frame_name"].location.href
which returns "about:blank" everytime I use it, is there something I can do to get this to work? Thanks.

Sorry, I didn't notice that that was one you tried. Can you give an example of exactly how you want it to look? If not www.site_domain.com/page.html what?

here is something you could try...

it probly doesnt really work right now but if the iframe is loaded as a window object you could use something like...

window.[objectname].location;
or
window.document.[objectname].location;
or
window.document.all.[objectname].location;

im sorry i cant test any of these but i am on vacation and i forgot my windows disks and, using msdos, complete screwed up my computer, i have to reformat my systemdrive and jumpdrive, i can only browse, edit, save and create files, i cant delete, move, copy, paste, rename, exc. it sucks but anyway this thread isnt about me so good luck with the above coding!!
