Question

我有這個代碼倒計時，應該打開captcha： 我找不到問題！請幫忙！

<script> 
    var seconds_left = 2; 
    var interval = setInterval(function() { 
     document.getElementById('timer_div').innerHTML = --seconds_left; 

     if (seconds_left <= 0) 
     { 
      document.getElementById('timer_div').innerHTML = "<div class='g-recaptcha' data-sitekey='mykey' style='transform:scale(0.77);-webkit-transform:scale(0.77);transform-origin:0 0;-webkit-transform-origin:0 0;'></div>"; 
      clearInterval(interval); 
     } 
     }, 1000); 
    </script> 
<div id="timer_div"></div> 

Answer 1

您可以從頭開始將reCaptcha div放入HTML中，但使其可見。然後從JavaScript，當2秒通過，使div可見。如下面的代碼：

HTML：

<div id="timer_div"></div> 

<div id="captcha" class='g-recaptcha' data-sitekey='mykey' style='display:none;transform:scale(0.77);-webkit-transform:scale(0.77);transform-origin:0 0;-webkit-transform-origin:0 0;'> 
RECAPTCHA 
</div> 

的JavaScript：

var seconds_left = 2; 
var timerDiv = document.getElementById('timer_div'); 
var captcha = document.getElementById('captcha'); 
timerDiv.innerHTML = seconds_left; 

var interval = setInterval(function() { 
    timerDiv.innerHTML = seconds_left; 
      seconds_left--; 


    if (seconds_left < 0) 
    {   
     timerDiv.style.display = "none"; 
     captcha.style.display = "block"; 
     clearInterval(interval); 
    } 

    }, 1000);
