Multiple urls in ignore field, still not working.

I had the same problem on version 1.3.1 and I have the following code that works on multiple urls (not so different where @mads_boll refers to:

(in file: open-external-links-in-a-new-window.php)

function external_links_in_new_windows_loop() {
    if (!document.links) {
	document.links = document.getElementsByTagName('a');
    }
    var change_link = false;
    var force = '".get_option("external_links_in_new_windows_force")."';
    var ignore = '".get_option("external_links_in_new_windows_ignore")."';

    var force_split = force.split(';');
    var ignore_split = ignore.split(';');

    for (var t=0; t<document.links.length; t++) {
	var all_links = document.links[t];
	change_link = false;

	if(document.links[t].hasAttribute('onClick') == false) {
	  // forced if the address starts with http (or also https), but does not link to the current domain
	  if(all_links.href.search(/^http/) != -1 && all_links.href.search('" . $blogdomain['host'] . "') == -1) {
              // alert('Changeda '+all_links.href);
	      change_link = true;
	}

	var found_force = -1;
        for (var i = 0; i < force.length; i++) {
              if (all_links.href.search(trim(force_split[i])) != -1) {
                 found_force = 0;
             }
        }

	var found_ignore = -1;
        for (var i = 0; i < ignore.length; i++) {
            if (all_links.href.search(trim(ignore_split[i])) != -1) {
                found_ignore = 0;
            }
        }

	if(force != '' && found_force != -1) {
	   // forced
	   // alert('force '+all_links.href);
	   change_link = true;
	}

	if(ignore != '' && found_ignore != -1) {
	  // alert('ignore '+all_links.href);
	  // ignored
	  change_link = false;
	}

	if(change_link == true) {
	  // alert('Changed '+all_links.href);
  	  document.links[t].setAttribute('onClick', 'javascript:window.open(\\''+all_links.href+'\\'); return false;');
	 document.links[t].removeAttribute('target');
	}
     }
  }
}
