Question

I have a table with an input field in a table row and an option boxe and I want, that the <tr> with the input field only appears when a specific value in the option box are selected. So far I have the following coding, it hides my <tr> with the input field, but never displays it again.

 $script = <<< EOF
<script type='text/javascript'>
    jQuery(document).ready(function($) {
        $('#row_sports').hide(); //works


         if($('#sel_rugby').is(':selected') || $('#sel_climbing').is(':selected')){
             $('#row_sports').show();

         }else{
            $('#row_sports').hide();
         }

    });
</script>
EOF;
        echo $script;


    echo '<table border="1">';
    echo '  <tr>';
    echo '      <td>';
    echo '          <select name="sports">';
    echo '              <option>Baseball</option>';
    echo '              <option id="sel_rugby">Rugby</option>';
    echo '              <option>Soccer</option>';
    echo '              <option>Sailing</option>';
    echo '              <option id="sel_climbing">Climbing</option>';
    echo '          </select>';
    echo '      </td>';
    echo '  </tr>';
    echo '  <tr id="row_sports">';
    echo '      <td>';
    echo '          <input name="sports_cl_rg" />';
    echo '      </td>';
    echo '  </tr>';
    echo '</table>';

<script type='text/javascript'>
    jQuery(document).ready(function($) {
        $('#row_sports').hide(); //works

        $('select').change(function() {
         if($('#sel_rugby').is(':selected') || $('#sel_climbing').is(':selected')){
             $('#row_sports').show();

         }else{
            $('#row_sports').hide();
         }
        });

    });
</script>

use change function too.. here it works
