有谁知道如何使Google ReCAPTCHA (v2)中的“form”成为“必需”？
我的意思是在重新填写之前没有表格提交？
我在我的形式中使用ParsleyJs，但没有找到一种方法使它与divs一起使用...
您必须使用reCaptcha验证响应回调。像这样：<script src='https://www.google.com/recaptcha/api.js?onload=reCaptchaCallback&render=explicit'></script>
var RC2KEY = 'sitekey',
doSubmit = false;
function reCaptchaVerify(response) {
if (response === document.querySelector('.g-recaptcha-response').value) {
doSubmit = true;
}
}
function reCaptchaExpired () {
/* do something when it expires */
}
function reCaptchaCallback () {
/* this must be in the global scope for google to get access */
grecaptcha.render('id', {
'sitekey': RC2KEY,
'callback': reCaptchaVerify,
'expired-callback': reCaptchaExpired
});
}
document.forms['form-name'].addEventListener('submit',function(e){
if (doSubmit) {
/* submit form or do something else */
}
})
对于ParsleyJS，您将做一些解决方法：
1.添加隐藏的输入字段，使用data-parsley-required="true"，value = ""，如下所示：
<input id="myField" data-parsley-errors-container="#errorContainer" data-parsley-required="true" value="" type="text" style="display:none;">
2.添加错误容器（在g-recaptcha div下方或下方）：
<span id='errorContainer'></span>
3.在你的js代码中的某处添加这个简单的函数：
function recaptchaCallback() {
document.getElementById('myField').value = 'nonEmpty';
}
4.使用自定义函数的值添加属性data-callback：
<div class="g-recaptcha" data-sitekey="***" data-callback="recaptchaCallback"></div>
你可以在这里找到另一个有效的例子：https://codepen.io/reactionmedia/pen/JVdmbB
在本例中，我将在表单中创建两个HTML元素：
<div id="botvalidator"></div>
<div id="captchaerrors"></div>
botvalidator将包含google recaptcha iframe，其中包含“我不是机器人”复选框。检查用户未单击“我不是机器人”复选框后，captchaerrors将包含错误。
重要提示：我们正在使用arri.js库，以便了解google recaptcha何时在DOM中添加新的g-recaptcha-response textarea元素，因为先前的DOM新节点插入验证不再有效。将recaptcha加载到页面中几分钟后会发生此事件。
您可以从：https://github.com/uzairfarooq/arrive/下载arri.js库
或直接从CDN提供商处插入，例如：https://cdnjs.cloudflare.com/ajax/libs/arrive/2.4.1/arrive.min.js
请记住在加载JQUERY库后插入所有库以避免错误。我正在使用Jquery 2.2.4版本
<script src="https://code.jquery.com/jquery-2.2.4.min.js" integrity="sha256-BbhdlvQf/xTY9gja0Dq3HiwQF8LaCRTXxZKRutelT44=" crossorigin="anonymous"></script>
另一个重要的事情是要记住以这种方式加载recaptcha库，以便在加载recaptcha后执行onloadCallback函数并“手动”渲染recaptcha
<script src="https://www.google.com/recaptcha/api.js?onload=onloadCallback&render=explicit"></script>
这是代码片段：
var onloadCallback = function() {
/**
* If we try to load page to show the congrats message we don't need to load recaptcha.
*/
if($("#botvalidator").length > 0) {
grecaptcha.render('botvalidator', {
'sitekey' : '6LeIxAcTAAAAAJcZVRqyHh71UMIEGNQ_MXjiZKhI',
'callback': cleanErrors
});
addCaptchaValidation();
/**
* We are going to use arrive library in order to check new google recaptcha
* element added after the current one is expired and then we will create new attributes for that element.
* Expires-callback google recaptcha is not working, probably it is executed before element creation.
* https://github.com/uzairfarooq/arrive/
*/
$(document).arrive("#g-recaptcha-response", function() {
// 'this' refers to the newly created element
addCaptchaValidation();
});
}
};
/** We are going to remove all errors from the container. */
var cleanErrors = function() {
$("#captchaerrors").empty();
};
var addCaptchaValidation = function() {
console.log("Adding captcha validation");
cleanErrors();
$('#myform').parsley().destroy();
$('#g-recaptcha-response').attr('required', true);
// We are going to create a new validator on Parsley
$('#g-recaptcha-response').attr('data-parsley-captcha-validation', true);
$('#g-recaptcha-response').attr('data-parsley-error-message', "We know it, but we need you to confirm you are not a robot. Thanks.");
$('#g-recaptcha-response').attr('data-parsley-errors-container', "#captchaerrors");
$('#myform').parsley();
};
/** We are going to add a new Parsley validator, this validation is called from
#g-recaptcha-response after clicking the submit button*/
window.Parsley.addValidator('captchaValidation', {
validateString: function(value) {
if(debug) console.log("Validating captcha", value);
if(value.length > 0) {
return true;
} else {
return false;
}
},
messages: {en: 'We know it, but we need you to confirm you are not a robot. Thanks.'}

创建一个规则https://laravel.com/docs/5.7/validation#custom-validation-rules
然后在您的控制器中使用它
// validation
$this->validate( $request, array(
'g_recaptcha_response' => ['required', 'string', new Captcha()]
));
