title: How to stay in a tab while opening a new one (open a file)?
body: <p>I have a link to open a <code>pdf</code> in a browser. But, It gets focused on the new tab (the tab with the <code>pdf</code>. How to prevent this behavior?</p>
  
  <p>This is the link:  </p>
  
  <pre><code>&lt;strong&gt;&lt;a style="text-decoration:none" class='row_link' href='javascript:void(0)' target="_blank" onFocus="false"&gt;Open File&lt;/a&gt;&lt;/strong&gt;
  </code></pre>
  
  <p>This is the jquery:  </p>
  
  <pre><code>$("#myTable tbody").on('click','.row_link', function(e) {
      var no_s    = $(this).find('.filename').val().replace(/\//g , '');
      var b_url   = $('#base_url').val()+"assets/uploads/file/";
  
      var url     = b_url + no_s;
      window.open(url);
  });
  </code></pre>
  
  <p>I've tried adding <code>onfocus="false"</code> in the anchor. But, It's no effect</p>
