You may try something like this

<script>
function validate()
{
 
  if (document.forms['myform'].elements['text1'].value.length)
  {
     // text1 has something in it
     if (document.forms['myform'].elements['select1'].selectedIndex == 0)
     {
        alert('You must pick an option if you\'ve typed text');
        return false;
      }
  }
  return true;
}
</script>
<form onsubmit="return validate()" name="myform">

<input type="text" name="text1">
<select name="select1">
  <option value="">Pick one</option>
  <option value="1">opt 1</option>
</select>

<input type="submit">
</form>
