我需要限制单击按钮，并且在下拉列表中选择的值将被禁用

<script type="text/javascript">
 function getVote(int)
 {
 if (window.XMLHttpRequest)
   {// code for IE7+, Firefox, Chrome, Opera, Safari
   xmlhttp=new XMLHttpRequest();
   }
  else
   {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
   }

    if(confirm("Your vote is for "+int))
     {
    xmlhttp.open("GET","save.php?vote="+int,true);
    xmlhttp.send();
      }
      else
    {
      alert("Choose another candidate ");   
        }

    }

    function getPosition(String)
    {
     if (window.XMLHttpRequest)
      {// code for IE7+, Firefox, Chrome, Opera, Safari
       xmlhttp=new XMLHttpRequest();
       }
     else

      xmlhttp.open("GET","vote.php?position="+String,true);
      xmlhttp.send();

     echo "</tr>";
     }

      mysql_free_result($result);
    mysql_close($link);
     //}
         }
     else
    // do nothing
            ?>

保存PHP：

<?php require('connection.php'); 
$vote = $_REQUEST['vote'];
mysql_query("UPDATE tbCandidates SET candidate_cvotes=candidate_cvotes+1 WHERE candidate_name='$vote'"); mysql_close($con); ?>

如何限制用户投票。我是否需要禁用用户单击的下拉列表值并禁用已禁用的单选按钮？请帮帮我。谢谢你希望我能完成这个。：（
