macOS running javascript from obj-C

(I posted this to the cocoadev mailing list, but thought id post it here also)

Hi,

I am currently trying to implement element blocking into my opensource Safari adblocker project:
http://code.google.com/p/safariadblocker/


And I was thinking of taking the approach, of feeding a javascript function to Safari:

function hide_elements(id)
{
document.getElementById(id).style.display="none";

}

where id would be fed to the script from the adblock list(An NSArray of NSStrings). I don't know javascript, so need to figure out how to do this also)

What I was wanting to know, is how do I apply the javascript to Safari?
any help would be appreciated.

thanks in advance

I found this:

its actually quite easy!
