Open Link in an External Window via Javascript

/ Published in: JavaScript
Save to your folder(s)

Rather than using target="_blank", which is deprecated by the W3C in XHTML, you should use rel="external" for links that you want to pop out in a new window. This is the javascript that makes it happen.

Copy this code and paste it in your HTML
  1. function externalLinks() {
  2. if (!document.getElementsByTagName) return;
  3. var anchors = document.getElementsByTagName("a");
  4. for (var i=0; i<anchors.length; i++) {
  5. var anchor = anchors[i];
  6. if (anchor.getAttribute("href") &&
  7. anchor.getAttribute("rel") == "external")
  8. = "_blank";
  9. }
  10. }
  11. window.onload = externalLinks;
