Add target _blank to all links

targeting.js

// All links pure JS solution
var anchors = document.getElementsByTagName('a');
for (var i=0; i < anchors.length; i++) {
  anchors[i].setAttribute('target', '_blank');
}

// All links w. jQuery
$('a').attr('target', '_blank');

// All outgoing links w. jQuery
$('a[href^="http://"]').not('a[href*=gusdecool]').attr('target','_blank');
