[adiaz]

Lot of thanks!

$(function() {
  function seturl(url) {
    $('#widget-2 iframe').prop('src', url);
  }

  $('.btn-1').on('vclick', function() {
    seturl('https://forum.logicmachine.net');
  });

  $('.btn-2').on('vclick', function() {
    seturl('http://openrb.com');
  });
});

Modified code for my use!

Which is the event to trigger On/Off the Widget?
