Is it possible to automatically make target blank for external links?

Question

JavaScript

Actually a question. Is it possible to have automatic behavior for ALL external links target blank, preferably by means of HTML? It seems there was a similar tag in the head that specifies this behavior? If you can’t use HTML, then what would you advise on JS (this is probably more difficult, because Vue is used, and even the content comes via the API as JSON and is rendered via v-html)

Answer 1

I haven't heard that about html.
Jquery

$(document).ready(function(){
  $('#content a').attr('target', '_blank');
});

js

window.onload = function(){
  var anchors = document.getElementById('content').getElementsByTagName('a');
  for (var i=0; i<anchors.length; i++){
    anchors[i].setAttribute('target', '_blank');
  }
}

+ Checking for a domain and adding:

$('#content a').each(function() {
   var linky = new RegExp('/' + window.location.host + '/');
   if (!linky.test(this.href)) {
      $(this).attr("target","_blank");
   }
});
