This was my last attempt, and I haven't been successful.
if(document.querySelectorAll("input[name='myRadioButton']").checked) {
alert("checked");
}
It must be something simple for JavaScript experts. Why is JavaScript so difficult?
PLEASE no jQuery.
you can use event listener to handle the input change like this :
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
</head>
<body>
<input type="radio" name="myradio" />
<input type="radio" name="myradio" />
<input type="radio" name="myradio" />
</body>
</html>
<script>
let radio = document.getElementsByName("myradio");
for (let i = 0; i < radio.length; i++) {
radio[i].addEventListener("input", () => {
alert("checked");
});
}
</script>
