Javascript 如何重置Google reCaptcha？

这是我的PHP代码：

    function post_captcha($user_response) {
    $fields_string = '';
    $fields = array(
        'secret' => '',
        'response' => $user_response
    );
    foreach($fields as $key=>$value)
    $fields_string .= $key . '=' . $value . '&';
    $fields_string = rtrim($fields_string, '&');
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://www.google.com/recaptcha/api/siteverify');
    curl_setopt($ch, CURLOPT_POST, count($fields));
    curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, True);
    $result = curl_exec($ch);
    curl_close($ch);
    return json_decode($result, true);
}
$res = post_captcha($_POST['g-recaptcha-response']);
if (!$res['success']) {
      die('MF005');
} else {
if ($mail->send()) { 
$send_arEmail = $autoresponder->Send();
}}

<script src="https://www.google.com/recaptcha/api.js" async defer></script>
<script>
function onSubmit(token) {
    document.getElementById("i-recaptcha").submit();
}
</script>

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

<button class="button rounded" type="submit" data-callback="onSubmit">Send</button>

这是我的JavaScript代码：

    function post_captcha($user_response) {
    $fields_string = '';
    $fields = array(
        'secret' => '',
        'response' => $user_response
    );
    foreach($fields as $key=>$value)
    $fields_string .= $key . '=' . $value . '&';
    $fields_string = rtrim($fields_string, '&');
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://www.google.com/recaptcha/api/siteverify');
    curl_setopt($ch, CURLOPT_POST, count($fields));
    curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, True);
    $result = curl_exec($ch);
    curl_close($ch);
    return json_decode($result, true);
}
$res = post_captcha($_POST['g-recaptcha-response']);
if (!$res['success']) {
      die('MF005');
} else {
if ($mail->send()) { 
$send_arEmail = $autoresponder->Send();
}}

<script src="https://www.google.com/recaptcha/api.js" async defer></script>
<script>
function onSubmit(token) {
    document.getElementById("i-recaptcha").submit();
}
</script>

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

<button class="button rounded" type="submit" data-callback="onSubmit">Send</button>

提交函数（令牌）{
document.getElementById（“i-recaptcha”）.submit（）；
}

这是我的验证码：

    function post_captcha($user_response) {
    $fields_string = '';
    $fields = array(
        'secret' => '',
        'response' => $user_response
    );
    foreach($fields as $key=>$value)
    $fields_string .= $key . '=' . $value . '&';
    $fields_string = rtrim($fields_string, '&');
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://www.google.com/recaptcha/api/siteverify');
    curl_setopt($ch, CURLOPT_POST, count($fields));
    curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, True);
    $result = curl_exec($ch);
    curl_close($ch);
    return json_decode($result, true);
}
$res = post_captcha($_POST['g-recaptcha-response']);
if (!$res['success']) {
      die('MF005');
} else {
if ($mail->send()) { 
$send_arEmail = $autoresponder->Send();
}}

<script src="https://www.google.com/recaptcha/api.js" async defer></script>
<script>
function onSubmit(token) {
    document.getElementById("i-recaptcha").submit();
}
</script>

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

<button class="button rounded" type="submit" data-callback="onSubmit">Send</button>

这是提交按钮：

    function post_captcha($user_response) {
    $fields_string = '';
    $fields = array(
        'secret' => '',
        'response' => $user_response
    );
    foreach($fields as $key=>$value)
    $fields_string .= $key . '=' . $value . '&';
    $fields_string = rtrim($fields_string, '&');
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://www.google.com/recaptcha/api/siteverify');
    curl_setopt($ch, CURLOPT_POST, count($fields));
    curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, True);
    $result = curl_exec($ch);
    curl_close($ch);
    return json_decode($result, true);
}
$res = post_captcha($_POST['g-recaptcha-response']);
if (!$res['success']) {
      die('MF005');
} else {
if ($mail->send()) { 
$send_arEmail = $autoresponder->Send();
}}

<script src="https://www.google.com/recaptcha/api.js" async defer></script>
<script>
function onSubmit(token) {
    document.getElementById("i-recaptcha").submit();
}
</script>

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

<button class="button rounded" type="submit" data-callback="onSubmit">Send</button>

发送

这也是我的表单id:

<form id="i-recaptcha">

**

上述功能正在运行，但在提交表单后，仍会验证码 如果选中，我想在用户单击提交后将其重置为未选中 按钮

提前感谢

您可以这样使用它。它是基于版本的

第3版

grecaptcha.ready(function() {
    grecaptcha.execute('SITE_KEY', {action: 'homepage'}).then(function(token){
        $('#token').val(token);
    });
});

第2版

grecaptcha.reset();

第1版

Recaptcha.reload();

我添加了这两个JavaScription，但它不起作用。我如何添加它？你使用的是哪个版本？我不知道哪个版本，你可以看到我上面的代码。请给我一个解决办法。感谢you@Zam85我认为这个grecaptcha.reset（）；可以为您工作。@Zam85请访问此网站了解有关v2和v3的更多信息。有什么幸运的事情吗？
