我集成了新的隐藏reCAPTCHA(v2)框架,该框架默认使用提交按钮的click
事件验证用户。但是在内置HTML5表单验证之前触发此事件。我正在寻找一种方法来按预期的顺序进行:首先是表单验证,然后是reCAPTCHA。
答案 0 :(得分:31)
由于采用了新的v2 grecaptcha
方法,您必须以编程方式执行此操作:grecaptcha.execute()
以便recaptcha不会替换按钮的默认点击事件,这会阻止默认的HTML5表单验证。
事件路径是:
grecaptcha.execute()
$('#form-contact').submit(function (event) {
event.preventDefault();
grecaptcha.reset();
grecaptcha.execute();
});
function formSubmit(response) {
// submit the form which now includes a g-recaptcha-response input
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://www.google.com/recaptcha/api.js"></script>
<form action="?">
<div class="g-recaptcha"
data-sitekey="your-key"
data-size="invisible"
data-callback="formSubmit">
</div>
<button type="submit">Submit</button>
</form>

你在这里得到了一个有效的解决方案。使用隐形Recaptcha。
jQuery(document).ready(function() {
var commentform = jQuery("#commentform");
commentform.on("click", "#submit-comment", function(e) {
if(commentform[0].checkValidity()) {
e.preventDefault();
grecaptcha.execute();
}
});
});
function submitCommentForm(data) {
document.getElementById("commentform").submit();
}
<form action="blaba.php" method="post" id="commentform" class="comment-form">
<div class="form-submit">
<div data-callback="submitCommentForm" data-sitekey="yourkey" class="g-recaptcha" data-size="invisible">
<button id="submit-comment">Leave a comment</button>
</div>
</form>

我想要同样的行为,但是使用新的recaptcha,看不见的那个。在查看了一些代码并测试了一些内容后,我深入研究了这个问题。主要区别在于此还使用默认浏览器验证:
var contact_form;
$(function() {
contact_form = $('#contact-form');
contact_form.submit(function (event) {
if ( ! contact_form.data('passed')) {
event.preventDefault();
grecaptcha.execute();
}
});
});
function sendContactForm(token) {
contact_form.data('passed', true);
contact_form.submit();
}
它基本上将jquery表单对象存储在全局var中,包括使用sendContactForm
作为回调,但是当由recaptcha调用时,它设置一个名为passed
的数据var,它允许形式不被阻止。这与recaptcha通常会做的完全相同,但是具有这种条件。
更新:重新查看我的代码,提醒我可能需要一种方法来恢复grecaptcha执行后传递给false
的数据。如果您要实现这一点,请考虑一下。

这是我的解决方法。
根据需要添加任意多个表单,只需在两个位置更改“ UNIQUE_FORM_ID”,然后更新该表单的POST_URL。 确保在“ RECAPTCHA_SITE_KEY”的位置中使用自己的密钥。
<form id="UNIQUE_FORM_ID" method="post" action="POST_URL">
<!-- ** Notice ** this hidden input field that will later send our g-recaptcha token back to our server -->
<input type="hidden" name="g-recaptcha-response" value="">
<!-- Add other hidden nonce fields -->
<!-- Required field -->
<input name="fullname" type="text" placeholder="Full Name" required>
<!-- Submit button -->
<!-- ** Notice ** the 'form' attribute; using SAME value as it's parent's form id, above. -->
<!-- ** Notice ** the 'onclick' attribute; be sure to pass event -->
<button type="submit" form="UNIQUE_FORM_ID" onclick="formSubmitBtn(event)">Send</button>
</form>
<!-- Only add scripts once -->
<!-- ** Notice ** to manually call grecaptcha, our site key must be included when loading api.js using the 'render' query param -->
<script src="https://www.google.com/recaptcha/api.js?render=RECAPTCHA_SITE_KEY"></script>
<script>
/**
* Handles form submissions for Google recaptcha v3.
* Allows for HTML5 form validation to complete before processing.
*/
function formSubmitBtn($event) {
/**
* Checks the validity of the form.
* Return if invalid; HTML5 validation errors should display.
*/
if (!$event.target.form.checkValidity()) {
return;
}
/**
* Form is client-side valid; taking over the remainder of processing.
*/
$event.preventDefault();
grecaptcha.ready(function() {
grecaptcha.execute("RECAPTCHA_SITE_KEY", { action: 'submit' }).then(function(token) {
/**
* Adds the token g-recaptcha-response token to our hidden form element.
* ** Notice ** we our referencing the specific form's input element by name here (do not use IDs).
*/
$event.target.form.elements['g-recaptcha-response'].value = token;
/**
* Use the form API directly to submit the form.
*/
$event.target.form.submit();
});
});
}
</script>

let siteKey = "...";
$("form").submit(function (eventObj) {
var myForm = this;
eventObj.preventDefault();
grecaptcha.execute( siteKey, {
action: "submit"
})
.then(function (token) {
$('<input />').attr('type', 'hidden')
.attr('name', "g_recaptcha_response")
.attr('value', token)
.appendTo(myForm);
myForm.submit();
});
});
这将执行recapcha,等待响应,并在浏览器尝试提交然后实际提交时将隐藏属性g_recaptcha_response添加到任何表单。您需要全局变量siteKey

我遇到了这个问题,因为默认方法似乎覆盖了html5表单验证。我还希望所有代码都是通用的,而不是硬编码任何函数/元素名称。最后,我使用v3 api提出了以下代码-
HTML
<form method="post" action="?" class="ui-recaptcha" name="my_form_name">
...
<input type="submit" value="Submit">
</form>
<script src="//www.google.com/recaptcha/api.js?render={key}" async defer></script>
JavaScript(我使用的是jQuery,但是很容易适应普通js)
$('.ui-recaptcha').submit(e => {
var form = e.target;
if( $(form).data('recaptcha-done') )
return;
e.preventDefault();
grecaptcha.execute('{key}', {'action': $(form).attr('name')}).then(token => {
$(form).append($('<input>').attr({'type': 'hidden', 'name': 'g-recaptcha-response', 'value': token}));
$(form).data('recaptcha-done', true);
$(form).submit();
});
});
我发现像上面的某些示例中那样仅调用submit
会给我造成一个循环,当recaptcha处理程序在submit
事件上运行时,这很有意义。
这将为任何ui-recaptcha
表单运行recaptcha,将表单name
属性作为操作在reCaptcha控制台中可见,然后将令牌插入表单。运行后,它将在表单上设置一个data属性,因此递归调用提交不会尝试再次运行recaptcha。
