title: Retrieve Table Row Index of Current Row
body: <p>I am trying to validate a text input when it loses focus.  I would like to know which row of the table it is in.  This is what I have so far and it keeps coming back as undefined.  Any ideas?</p>
  
  <pre><code>$("div#step-2 fieldset table tbody tr td input").blur(function() {
      var tableRow = $(this).parent().parent();
      if ($.trim($(this).val()) == "") {
          $(this).addClass("invalid");
          alert(tableRow.rowIndex);
          $(this).val("");
      } else {
          $(this).removeClass("invalid");
          checkTextChanges();
      }
  });
  </code></pre>
