java中的簡單驗證碼音頻設置

我有一個表格，我已經實現了Simple captcha每件事情都很好，但我希望當用戶點擊播放按鈕時播放音頻驗證碼。在我的情況下音頻播放默認在頁面加載。java中的簡單驗證碼音頻設置

下面是我的音頻驗證碼

public class MyAudioCaptcha extends AudioCaptchaServlet { 

/** 
* 
*/ 
private static final long serialVersionUID = 1L; 

public void doGet(HttpServletRequest req, HttpServletResponse resp) 
     throws ServletException, IOException { 
    try { 

     MyTextProducer myTextProducer = (MyTextProducer) req.getSession().getAttribute("myTextProducer"); 
     if(myTextProducer == null){ 
      myTextProducer = new MyTextProducer(); 

     } 
     AudioCaptcha ac = new AudioCaptcha.Builder(). 
       addAnswer(myTextProducer). 
       addNoise(). 
       build(); // Required 

       CaptchaServletUtil.writeAudio(resp, ac.getChallenge()); 
       req.getSession().setAttribute("audioCaptcha", ac); 
    } catch (Exception e) { 
     Util.AppendExceptionToLog(e); 
    } 

    } 
}

JSP代碼代碼：

<script> 
     $(document).ready(function(){ 
      reloadCaptcha(); 
     }); 
     function reloadCaptcha(){ 
     var d = new Date(); 
     $.ajax({ 
      url:"captcha.jsp", 
      type :"POST", 
      async:true, 
      data: { 
      'action': 'generateCaptcha' , 
      }, 
     success:function(response){ 
      $("#captcha_image").attr("src", "../../simpleCaptcha.png?"+d.getTime()); 
      $("#captcha_audio").attr("src", "../../audio.wav?"+d.getTime()); 

     }, 
    });  

    } 
    </script> 
<body> 
    <td> 
    <div class="inputfield" style="margin-left: 10px;"> 
     <img id="captcha_image" /> 
     <img src="../../images/reload.jpg" onclick="reloadCaptcha()" style="cursor: pointer;" alt="reload"width="30" height="30"/> 
    </div> 
    </td> 
    <td> 
     <audio controls autoplay id="captcha_audio" autoplay = "false"></audio> 
    </td> 
</body>

有沒有在上面的代碼中的任何配置的，因此音頻不會在頁面加載播放，要播放的只有用戶點擊音頻captcha
