title: JQUERY get list of checkboxes that are checked by ID
body: <p>I currently have a list of checkboxes all with the same ID which are hidden and I want to grab the list of the ones that are checked, is this possible? I am currently using this format:</p>
  
  <pre><code>selected_list = $("#ID").attr("checked", "true");
  </code></pre>
  
  <p>this however is only returning the top one when I read them into a variable with a loop like this:</p>
  
  <pre><code>list = '';
  $(selected_list).each(
      function() {
            list += $(this).val() + " ";
      } 
  );
  
  alert(list);
  </code></pre>
  
  <p>Anyone know of a better way of doing this or why my version is only returning the first checkbox? Thanks</p>
