Barrierfree Links in new window

XHTML Strict denys the use of target=„_blank“ in <a> elements. With the following code in the head-part of your html-files you can use <a href=„#“ rel=„external“>Link</a> in a barrierfree way.

<!-- Javascript -->
<script type="text/javascript">
<!--
function setExternalLinks() {
	if (!document.getElementsByTagName) {
       		return null;
	}
	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.setAttribute("target", "blank");
       			}
		}
	}
window.onload = setExternalLinks;
-->
</script>
