title: Loop over html table and get checked checkboxes (JQuery)
body: <p>I have an HTML table with a checkbox in each row.<br>
  I want to loop over the table and see if there are any checkboxes that are checked.<br>
  The following does not work:  </p>
  
  <pre><code>$("#save").click( function() {
      $('#mytable tr').each(function (i, row) {
          var $actualrow = $(row);
          checkbox = $actualrow.find('input:checked');
          console.log($checkbox);
  });
  </code></pre>
  
  <p>This prints in the console the following:  </p>
  
  <p><code>[prevObject: jQuery.fn.jQuery.init[1], context: tr, selector: "input:checked", constructor: function, init: function…]</code>  </p>
  
  <p>per row regardless of whether any checkbox is checked.  </p>
  
  <p><strong>Update</strong><br>
  Same issue with:  </p>
  
  <pre><code>$('#mytable tr').each(function (i, row) {                                                                                                 
     var $actualrow = $(row);
      $checkbox = $actualrow.find(':checkbox:checked');
      console.log($checkbox);  
  });
  </code></pre>
