我只是在提交表单后尝试让Google Invisible ReCaptcha工作 . 我的问题是,ReCaptcha不是看不见的,看起来像是“旧的”重新出现了 . 我不明白为什么 . 我的网站密钥是无形的recaptcha . 请帮我 .
首先,我正在加载API:
<script src='https://www.google.com/recaptcha/api.js?render=explicit&onload=onScriptLoad' async defer></script>
我的表单看起来像这样:
<form method="post" id="contact-form-face" class="clearfix" onsubmit="return false">
<input type="text" required name="name" value="name" onFocus="if (this.value == 'name') this.value = '';" onBlur="if (this.value == '') this.value = 'name';" />
<button type="submit" id="sendButton" data-size="invisible" class="g-recaptcha contact_btn" onclick="onSubmitBtnClick()" value="send" >send</button>
</form>
JS:
window.onScriptLoad = function () {
// this callback will be called by recapcha/api.js once its loaded. If we used
// render=explicit as param in script src, then we can explicitly render reCaptcha at this point
// element to "render" invisible captcha in
var htmlEl = document.querySelector('.g-recaptcha');
// option to captcha
var captchaOptions = {
sitekey: 'XXXXXXX',
size: 'invisible',
// tell reCaptcha which callback to notify when user is successfully verified.
// if this value is string, then it must be name of function accessible via window['nameOfFunc'],
// and passing string is equivalent to specifying data-callback='nameOfFunc', but it can be
// reference to an actual function
callback: window.onUserVerified
};
// Only for "invisible" type. if true, will read value from html-element's data-* attribute if its not passed via captchaOptions
var inheritFromDataAttr = true;
console.log("render now!");
// now render
recaptchaId = window.grecaptcha.render(htmlEl, captchaOptions, inheritFromDataAttr);
};
// this is assigned from "data-callback" or render()'s "options.callback"
window.onUserVerified = function (token) {
alert('User Is verified');
console.log('token=', token);
};
// click handler for form's submit button
function onSubmitBtnClick () {
var token = window.grecaptcha.getResponse(recaptchaId);
// if no token, mean user is not validated yet
if (!token) {
// trigger validation
window.grecaptcha.execute(recaptchaId);
return;
}
var xhrData = {
'g-recaptcha-response': token
// more ajax body/data here
};
};
为了使事情更清楚:这个reCaptcha工作正常,回调加载,验证工作也正常....唯一的问题是,这个recaptcha必须是invisibile,而不是:/

我认为你的问题是你明确地调用了render()方法
};
如果您希望它不可见,则必须包含此自定义DIV
https://developers.google.com/recaptcha/docs/invisible
recaptcha脚本将查找div类元素并将其绑定在那里,然后在调用recaptcha验证时执行回调 .
调用recaptcha验证使用grecaptcha.execute();
按照googledev页面中的示例,非常简单 .
我希望有帮助=)
我想你错过了"captchaOptions"中的badge参数 .
有3个可能的值:bottomright(默认值),bottomleft和 inline (可让您自定义recaptcha的css) .
查看JavaScript API文档,https://developers.google.com/recaptcha/docs/invisible#js_api您需要添加一个带有要呈现的id的div,当您使用JavaScript呈现验证码时,按钮元素上不需要类和数据属性 .
你的HTML应该是:
你的JS应该更新为:
