<title>Checkbox demo</title>
</head>
<body>
<span>Checkbox:</span>
<input type="checkbox" id="my-checkbox" onclick="myFunction()">
<p id="result">Page loaded</p>
<script>
function myFunction() {
var checkBox = document.getElementById("my-checkbox");
var result = document.getElementById("result");
if (checkBox.checked == true){

尝试这个:
<!DOCTYPE html>
<html>
<head>
<style>
input:checked {
height: 50px;
width: 50px;
}
</style>
</head>
<body>
<form action="">
<input type="radio" checked="checked" value="male" name="gender"> Male<br>
<input type="radio" value="female" name="gender"> Female<br>
<input type="checkbox" checked="checked" value="Bike"> I have a bike<br>
<input type="checkbox" value="Car"> I have a car
</form>
</body>
</html>
