may please seek help? want highlight or blink row when value in trem (third column) reaches 00:00. css right basic/simple : https://jsfiddle.net/8lfj3h0j/

really need help.

since cannot yet comment, going ask way. can please bit more specific. trem value looks counter. want checking value of row javascript, , if value 00.00 change css class javascript.

$('#elementid').toggleclass('yourcssclass'); 

if not mean means feel free correct me or clarify question:)

edit: in php function "current" can check if value 00.00 if statement. call javascript function if value 00.00 should this:

function current() { if(parent::current()=="00.00"){ echo '<script type="text/javascript">'    , '$('#elementid').toggleclass('yourcssclass');'    , '</script>' ;}else{}      return "<td style='width: 100px; border: 1px solid black;'>" . parent::current(). "</td>";     } 

note: have little experience recursiveiterator classes can not tell certaincy parent::current()=="00.00" work, should general idea of checking value , calling js function.

edit: copy pasted comment

<?php   $i=0; while($array=sqlsrv_fetch_array($data)){   $countervariable=parent::current();   //not sure if above line works theory  ?>  <tr data-id="<?php echo $i; ?>">       <td><?php echo $array['product_id']; ?></td>        <td><?php echo $array['product_name']; ?></td>       <td><?php echo $countervariable ?></td>  </tr>  <?php $i=$i+1; }?>
