我刚刚将无形的recaptcha实现到网络表单中。一切都适用于Chrome。但是对于Microsoft Edge，每次提交表单时都会出现图像质询。这对网站用户来说很尴尬。一个想法？
非常感谢您的见解和建议：o）

Javascript代码：
window.onScriptLoad = function () {
var htmlEl = document.querySelector('.g-recaptcha');
var captchaOptions = {
'sitekey': 'xxxxxxxxxxxxxxxxxxxxxxxxxxx',
'size': 'invisible',
'badge': 'inline',
callback: window.onUserVerified
};
var inheritFromDataAttr = true;
recaptchaId = window.grecaptcha.render(htmlEl, captchaOptions, inheritFromDataAttr);
};
window.onUserVerified = function (token) {
$.ajax({
url: 'process.php',
type: 'post',
dataType: 'json',
data : {
'lastname' : $("#lastnameField").val(),
'firstname' : $("#firstnameField").val(),
'city' : $("#cityField").val(),
'postalCode' : $("#postalcodeField").val(),
'g-recaptcha-response' : token
},
success:function(data) {
// informs user that form has been submitted
// and processed
},
error: function(xhr, textStatus, error){
// informs user that there was a problem
// processing form on server side
}
});
};
function onSubmitBtnClick () {
window.grecaptcha.execute;
}
HTML code：
<html>
<head>
<script src="https://www.google.com/recaptcha/api.js?render=explicit&onload=onScriptLoad" async defer></script>
<script type="text/javascript" src="js/petition.js"></script>
...
</head>
<body>
<form id="petitionForm" onsubmit="return false;">
<input id="lastnameField" type="text" name="lastname" placeholder="Lastname" required value="Doe">
<input id="firstnameField" type="text" name="firstname" placeholder="Firstname" required value="John">
<input id="postalcodeField" type="text" name="postalCode" placeholder="Postal Code" required value="ABCDEF">
<input id="cityField" type="text" name="city" placeholder="City" value="Oslo">
....
<input type="submit" name="login" class="g-2" data-sitekey="xxxxxxxxxxxxxxxxxxxxxxx" id="signButton" data-callback='' value="Signer" onclick="onSubmitBtnClick();">
<div class="g-recaptcha" id="recaptchaElement" style="align-content: center"></div>
</form>
