javascript - Formvalidation.io - 无法读取 null 的属性 'classList'

Question

使用 formvalidation.io 时，我的控制台总是出现错误。

我不知道这个错误的原因是什么。我在某些网站上仍然会收到垃圾邮件，即使我正在使用 backendVerificationURL。我正在使用 Invisible ReCaptcha ( https://formvalidation.io/guide/plugins/recaptcha/ )

我的 HTML 表单:

                                <form id="contact" method="post" action="/vendor/contact-form.php">
                                <div class="card-body">
                                    <div class="row">
                                        <div class="col-md-6">
                                            <div class="form-group label-floating is-empty">
                                                <label class="bmd-label-floating">Naam</label>
                                                <input type="text" name="naam" id="naam" class="form-control">
                                                <span class="material-input"></span>
                                            </div>
                                        </div>
                                        <div class="col-md-6">
                                            <div class="form-group label-floating is-empty">
                                                <label class="bmd-label-floating">Telefoonnummer</label>
                                                <input type="text" name="telefoon" id="telefoon" class="form-control">
                                                <span class="material-input"></span>
                                            </div>
                                        </div>
                                    </div>
                                    <div class="form-group label-floating is-empty">
                                        <label class="bmd-label-floating">Mailadres</label>
                                        <input type="email" name="email" id="email" class="form-control">
                                        <span class="material-input"></span>
                                    </div>
                                    <div class="form-group label-floating is-empty">
                                        <label for="bericht" class="bmd-label-floating">Uw bericht</label>
                                        <textarea name="bericht" class="form-control" id="bericht" rows="6"></textarea>
                                        <span class="material-input"></span>
                                    </div>
                                </div>
                                <div class="card-footer justify-content-between">
                                    <div class="form-check">
                                        <!-- De captcha container -->
                                        <div id="captchaContainer"></div>
                                    </div>
                                    <button type="submit" class="btn btn-brown">Aanvragen</button>
                                </div>
                            </form>

这是我的验证脚本 (validation-contact.js):

document.addEventListener('DOMContentLoaded', function(e) {
FormValidation.formValidation(
    document.getElementById('contact'),
    {
    fields: {

        naam: {
            validators: {
                notEmpty: {
                    message: 'Vul alstublieft uw naam in'
                }
            }
        },
        telefoon: {
            validators: {
                phone: {
                    country: 'NL',
                    message: 'U heeft een ongeldig telefoonnummer ingevuld'
                },
                notEmpty: {
                    message: 'Vul alstublieft uw telefoonnummer in'
                }
            }
        },
        email: {
            validators: {
                notEmpty: {
                    message: 'Vul alstublieft uw emailadres in'
                },
                emailAddress: {
                    message: 'U heeft een ongeldig emailadres ingevuld'
                }
            }
        },
    },
    plugins: {
        trigger: new FormValidation.plugins.Trigger(),
        bootstrap: new FormValidation.plugins.Bootstrap(),
        submitButton: new FormValidation.plugins.SubmitButton(),
        defaultSubmit: new FormValidation.plugins.DefaultSubmit(),
        icon: new FormValidation.plugins.Icon({
            valid: 'fa fa-check',
            invalid: 'fa fa-times',
            validating: 'fa fa-refresh',
        }),
        recaptcha: new FormValidation.plugins.Recaptcha({
            element: 'captchaContainer',
            message: 'The captcha is not valid or expired',
            // Replace with the site key provided by Google
            siteKey: 'MYSITEKEY',
            badge: 'bottomleft',
            theme: 'light',
            size: 'invisible',
            backendVerificationUrl: '/vendor/verification-url.php',
        }),
    },
})

});

我在 FormValidaiton.io 的 1.3 版中遇到了一个非常相似的问题。为了它的值(value)，为了防止它对你有帮助，我通过将任何 form-check DIV 元素嵌套在 form-group DIV 中解决了我的问题。

<div class="form-group"><div class="form-check"></div></div>

另一种有效的替代方法是使用 rowSelector 选项 - 如此处示例中所指定。
