  <script type="text/javascript">
      window.onload=function(){
          var send=document.getElementById('send'),
              times=59,
              timer=null;
          send.onclick=function(){
            send.value="60秒后重试"
            send.disabled="false";  
      timer=setInterval(function(){
            send.value=times+"秒后重试"
            send.disabled="false";  
            times--;
            if(times<=0){
                clearInterval(timer);
                send.removeAttribute("disabled");
                send.value="发送验证码";
                times=10;
            }
      },1000);   
          } 
      }
      </script>

  这样就不会有任何延迟了
