[HELP]someone knowledgable in jQuery

[Dr.CustUmz]

so we have a html link

<a href="http://google.com">Google</a>

and we target the google.com part like this

return this.each(function(){
    var link = $(this);
    var url = settings.service
    .replace("__URL__" , link.attr("href"))
    .replace("__DOMAIN__", link.attr("href")
    .replace("http://","").replace("https://", ""));.......more code

and this works, for my normal href's

but i want to target a link like this

<a href="out.php?link=http://google.com">Google</a>

so the end __URL__ is only "google.com"

i have tried many ways, and looking at this code the obvious replace has been done
replace("out.php?link=http://","").replace("out.php?link=https://", "")

im stuck, i set a demo up HERE

Might be easier to make use of split like this:

"out.php=?link=http://google.com".split('//')[1]

will output "google.com".

[Dr.CustUmz]

did you take a look at the demo dave? i implemented the split but im still not getting the desired results

this is the full code

jQuery.fn.favicons = function(config){
  var settings = jQuery.extend({
    "classname": "favicon",
    "service": "http://api.byi.pw/favicon?url=__URL__"
  }, config);

  return this.each(function(){
    var link = $(this);
    var url = settings.service
                .replace("__URL__" , link.attr("href"))
                .replace("__DOMAIN__", link.attr("href")
                .replace("http://","").replace("https://", ""));
    link.css("background-image", "url(" + url + ")")
                .addClass(settings.classname);
  });
};
