There are several ways to load reCAPTCHA using javascript such as below:
<html>
<head>
<title>Loading captcha with JavaScript</title>
<script src="https://code.jquery.com/jquery-1.12.0.min.js"></script>
<script type='text/javascript'>
var captchaContainer = null;
var loadCaptcha = function() {
captchaContainer = grecaptcha.render('captcha_container', {
'sitekey' : 'Your sitekey',
'callback' : function(response) {
console.log(response);
}
});
};
</script>
</head>
<body>
<div id="captcha_container"></div>
<input type="button" id="MYBTN" value="MYBTN">
<script src="https://www.google.com/recaptcha/api.js?onload=loadCaptcha&render=explicit" async defer></script>
</body>
</html>
This code load captcha on pageload. I want load reCAPTCHA just when clicked on "MYBTN". So the code changes into:
<html>
<head>
<title>Loading captcha with JavaScript</title>
<script src="https://code.jquery.com/jquery-1.12.0.min.js"></script>
<script type='text/javascript'>
$('#MYBTN').on('click',function(){
var captchaContainer = null;
var loadCaptcha = function() {
captchaContainer = grecaptcha.render('captcha_container', {
'sitekey' : 'Your sitekey',
'callback' : function(response) {
console.log(response);
}
});
};
});
</script>
</head>
<body>
<div id="captcha_container"></div>
<input type="button" id="MYBTN" value="MYBTN">
<script src="https://www.google.com/recaptcha/api.js?onload=loadCaptcha&render=explicit" async defer></script>
</body>
</html>
But this code didn't work when I click on "MYBTN" and reCAPTCHA not load. Help me plz. Thanks.

Launch Google Chrome and go to the three-dot menu. Now, click on the Help > About Chrome option. It will now search for the latest update automatically and install it. After updating Chrome, restart it and go to the reCAPTCHA site to see if it is working fine now.
You just need to call loadCaptcha()
$('#MYBTN').on('click',function(){
var captchaContainer = null;
var loadCaptcha = function() {
captchaContainer = grecaptcha.render('captcha_container', {
'sitekey' : 'Your sitekey',
'callback' : function(response) {
console.log(response);
}
});
};
loadCaptcha(); // THIS LINE WAS MISSING
});<script src="https://code.jquery.com/jquery-1.12.0.min.js"></script>
<div id="captcha_container"></div>
<input type="button" id="MYBTN" value="MYBTN">
<script src="https://www.google.com/recaptcha/api.js?onload=loadCaptcha&render=explicit"></script>Simple situation
Html
<input type="button" id="MYBTN" value="create captcha">
<div id="captcha_container"></div>
JS
var testSitekey = '6LeLzA4UAAAAANNRnB8kePzikGgmZ53aWQiruo7O';
$('#MYBTN').click(function() {
$('body').append($('<div id="captcha_container" class="google-cpatcha"></div>'));
setTimeout(function() {
grecaptcha.render('captcha_container', {
'sitekey': testSitekey
});
}, 1000);
});
