body: <p>How can I remove a selected Object in Fabric js </p>
  
  <p>Currently I can remove one selected object like following:</p>
  
  <pre><code>function removeCurrentObject(canvas) {
      $('#remove-current-object').click(function() {
          canvas.getActiveObject().remove();
      });
  }
  </code></pre>
  
  <p>But how can I check wether the user selectes more objects and remove them on an Event(click)</p>
