I am trying to find out a way in javascript to check if browser has Third-party cookie enabled or not , following apporach i’ve used but still there is no luck .
There are two files 1) Indec.html which contains following code:
<!doctype html>
<html>
<head>
</head>
<body>
<script>
function cookieTest(iFrameUri, callBack) {
function messageHandler(event) {
// Check for trusted origins here
const data = JSON.parse(event.data);
callBack(data["result"]);
window.removeEventListener("message", messageHandler);
document.body.removeChild(frame);
}
window.addEventListener("message", messageHandler);
var frame = document.createElement("iframe");
frame.src = iFrameUri;
frame.sandbox = "allow-scripts allow-same-origin";
frame.style = `display:none`;
frame.onload = function(e) {
frame.contentWindow.postMessage(JSON.stringify({ test: "cookie" }), window.location.origin);
};
document.body.appendChild(frame);
}
// Call the cookieTest function
cookieTest('iframe.html', function(result) {
// Callback function to handle the result
console.log('Cookies enabled:', result);
// Display the result on the page
var resultElement = document.getElementById('result');
resultElement.textContent = 'Cookies enabled: ' + result;
});
</script>
<h1>Cookie Test</h1>
<div id="result"></div>
</body>
</html>
Another one is iframe.html which contains the following code:
<!doctype html>
<html>
<head>
</head>
<body>
<script>
const checkCookiesEnable = () => {
let isCookieEnabled = (window.navigator.cookieEnabled) ? true : false;
if (typeof window.navigator.cookieEnabled == "undefined" && !isCookieEnabled) {
document.cookie = "testcookie";
isCookieEnabled = (document.cookie.indexOf("testcookie") != -1) ? true : false;
}
return isCookieEnabled;
}
(function () {
window.addEventListener('message', event => {
try {
let data = JSON.parse(event.data);
if (data['test'] !== 'cookie')
return;
let result = checkCookiesEnable();
parent.postMessage(JSON.stringify({ 'result': result }), event.origin);
} catch (e) {
console.error(e);
}
});
})();
</script>
</body>
</html>
Yet i am still getting third-party cookie enabled in incognito mode. Please help here.
