Google reCAPTCHA（如果按F5鍵）

如果按F5鍵，我想啓用Google reCAPTCHA。我有此代碼的那一刻：Google reCAPTCHA（如果按F5鍵）

<html> 
 
<head> 
 
<title>HELLO</title> 
 
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<script src='https://www.google.com/recaptcha/api.js'></script> 
 
<script type="text/javascript"> 
 
document.onkeydown = fkey; 
 
document.onkeypress = fkey 
 
document.onkeyup = fkey; 
 

 
var wasPressed = false; 
 

 
function fkey(e){ 
 
     e = e || window.event; 
 
     if(wasPressed) return; 
 

 
     if (e.keyCode == 116) { 
 
      alert("f5 pressed"); 
 
      // here the Google reCAPTCHA code have to come. 
 
      wasPressed = true; 
 
     }else { 
 
      alert("Window closed"); 
 
     } 
 
} 
 
</script> 
 
</head> 
 
<body> 
 
<p>If you press F5 you will get a Google reCAPTCHA</p> 
 
</body> 
 
</html>

<div class="g-recaptcha" data-sitekey="6LehRSETAAAAAIl2C3nRFguErdFn02smPN_vtPro"></div>

這是展示了谷歌驗證碼的代碼。

我希望有人能幫助我，所以我可以走得更遠。謝謝：d

我已經加入了e.preventDefault（），以阻止刷新瀏覽器。您可以根據需要修改上述內容。 – Siddharth
