Automatically setting link's TARGET to _blank if it doesn't point to my site

[stickynote427]

Is there some way in PHP (or some other language maybe?) that I can automatically set a link's TARGET attribute to _blank if that link does not point to a page on my site?

 

For example, if I have <a href="http://www.mysite.com/">My Site</a>, it should be left alone, but if I have <a href="http://www.phpfreaks.com">PHP Freaks</a>, it should automatically open in a new window when clicked.

 

Any information is helpful.

 

Thanks.

How are you generating these mysterious links? Are they all generated using PHP? Or, are you manually, statically placing them in various positions throughout your site?

there definitely is possible with php because I used this method before on my old websites, although! Its much easier with javascript!

 

<Script>
// change your domain name:
var yourURL = "localhost";
function outLinks() {
  var outLink;
  if (document.getElementsByTagName('a')) {
    for (var i = 0; (outLink = document.getElementsByTagName('a')[i]); i++) {
      if (outLink.href.indexOf(yourURL) == -1) {
        outLink.setAttribute('target', '_blank');
      }
    }
  }
}
window.onload = function() {
    outLinks();
}
</script>

(also I take no credit for this found this online)

just place anywhere in header section of file, and change localhost to youwebsite.com

@BK87: The method you provided is acceptable, I believe. Thank you very much.
