show table row if select menu equals 1

I have previously used the javascript code below to show / hide a table based a check box:

<script language="javascript">
      $("document").ready(function() {
            if (!$("#phone_support").attr('checked')) $(".captionRow").show();
            $("#phone_support").click(function(){
                  if ($("#phone_support").attr('checked')) $(".captionRow").hide();
                  else $(".captionRow").show();
                  })
            });
</script>

How do I change it so the captionRow class only shows if the value of the below select menu is 1?

<select name="ink_brand_id" id="ink_brand_id">
        <?php
do {  
?>
        <option value="<?php echo $row_rs_ink_brand['id']?>"><?php echo $row_rs_ink_brand['ink_brand']?></option>
        <?php
} while ($row_rs_ink_brand = mysql_fetch_assoc($rs_ink_brand));
  $rows = mysql_num_rows($rs_ink_brand);
  if($rows > 0) {
      mysql_data_seek($rs_ink_brand, 0);
        $row_rs_ink_brand = mysql_fetch_assoc($rs_ink_brand);
  }
?>
      </select>

Thanks, but it's not working for me. Can you please check:

<script language="javascript">
      $("document").ready(function() {
                  if( $('#ink_brand_id option:selected').attr('value')==1 )$(".captionRow").show();
            $('#ink_brand_id option:selected').click(function(){
                  if( $('#ink_brand_id option:selected').attr('value')!=1 )$(".captionRow").hide();
                  else $(".captionRow").show();
                  })
            });
</script>

my guess you want to show/hide upon change. If so, try:
<!DOCTYPE html>
<html>
<head>
  <style>
  div { color:red; }
  .captionRow{display:none;}
  </style>
  <script src="http://code.jquery.com/jquery-1.4.4.js"></script>
</head>
<body>
  <select name="ink_brand_id" id="ink_brand_id">
    <option value="0">Flowers</option>
    <option value="1" selected="selected">Shrubs</option>
    <option value="2">Trees</option>
    <option value="3">Bushes</option>
    <option value="4">Grass</option>
    <option value="5">Dirt</option>
  </select>
  <div></div>
<script language="javascript">
      $("document").ready(function() {
	 	$('#ink_brand_id').bind('change',function(){
			if( this.selectedIndex > -1  && this.options[this.selectedIndex].value==1)
				$(".captionRow").show();
			else
				$(".captionRow").hide();
		});
		$('#ink_brand_id').change();
      });
</script>
<div class="captionRow">Hi</div>
</body>
</html>
