Loading ...rel=”external”
February 2nd, 2006
for those who did not know this trick (someone emailed me and asked), I will share it with you here. since xhtml 1.0 strict does not allow the tag target=”_blank” you can still open links in new windows by using the tag rel=”external” to accomplish the same thing. but you will need to link an external js.
create a .js file with the content
function externalLinks() {
if (!document.getElementsByTagName) return;
var anchors = document.getElementsByTagName("a");
for (var i=0; i<anchors.length; i++) {
var anchor = anchors[i];
if (anchor.getAttribute("href") && anchor.getAttribute("rel") == "external") anchor.target = "_blank";
}
}
window.onload = externalLinks;
save & upload it. then link it in your header like any other external javascripts. that’s all 
Thanks! is the desired information - has long searched…
