Is it possible to run a code or a function on link click to manipulate the clicked link url?
Thanks

You need to attach an event handler to the link (element.addEventListener). Then you can do whatever you want.

See Pitfall #2 here: http://www.oreillynet.com/pub/a/network/2005/11...

Thanks for the reply.
Can I set this event handler to all links without parsing and identifying each one of them?
Doing so will make my script process links that the user would never click.

Some events can be intercepted by an element that contains the element that's actually clicked. You could try adding a click event listener on the page and see whether you can detect it there.

function gotClicked(e){
  if (e.target.nodeName.toLowerCase() = "a"){ // it's a link!
    // some actually useful code
  }
}
