title: How to get a count of checkboxes checked on pagination Jquery dataTables
body: <p>Below is my code, I want to get the count of checked checkboxes of all pages in my DataTable. Please advice how to proceed</p>
  
  <pre><code> &lt;td align="center"&gt;&lt;input type="checkbox" align="center" id="all" class="groupCheckBox" name="emails[]" value=' . $user['id'] . '&gt;&lt;/td&gt;
  </code></pre>
  
  <p>Below code I used for get the values of checked boxes in all pages on button click</p>
  
  <pre><code> $('#merge_button').click(function () {   
           var id = ""; 
           var oTable = $("#userTable").dataTable(); 
           $(".groupCheckBox:checked", oTable.fnGetNodes()).each(function () { 
  
               if (id != "") { 
                   id = id + "," + $(this).val(); 
               } else { 
                   id = $(this).val(); 
               } 
  
               document.getElementById("email").value = id; 
           }); 
      }); 
  </code></pre>
