Question

有谁知道如何制作＆＃34; Google ReCAPTCHA (v2)＆＃34; be＆＃34;必需＆＃34;在form？

我的意思是在重新填写后才会提交表单？

我在我的表单中使用ParsleyJs，但没有找到一种方法使其与div一起使用...

Answer 1

您必须使用reCaptcha验证响应回调。这样的事情：<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，您需要做一些解决方法：

1.添加隐藏的输入字段，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（位于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>

您可以在此处找到另一个可行的示例：https://codepen.io/reactionmedia/pen/JVdmbB

在此示例中，我将在表单内创建两个HTML元素：

<div id="botvalidator"></div>
<div id="captchaerrors"></div>

botvalidator 将包含带有“我不是机器人”复选框的google recaptcha iframe。确认用户未点击“我不是机器人”复选框后，验证码错误将包含错误。

重要提示：我们正在使用到达.js库，以了解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，就会发生此事件。

您可以从以下位置下载到达库： https://github.com/uzairfarooq/arrive/

或直接从CDN提供程序插入它，例如： https://cdnjs.cloudflare.com/ajax/libs/arrive/2.4.1/arrive.min.js

请记住在加载JQUERY库之后插入所有库，以避免发生错误。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”呈现Recaptcha。

<script src="https://www.google.com/recaptcha/api.js?onload=onloadCallback&render=explicit"></script>

这是代码段：

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()]
));
