  <p>Now I want to get the id of first row from . The id in this case is <code>reb1_1</code>. For getting it I tried below code but it didn't work.</p>
  
  <pre><code>$(document).ready(function() {
  $('.products').click(function () {
  var row = $(this).closest('table tbody:tr:first').attr('id');
      alert(row);
  });
  
  });
  </code></pre>
