confirm function is not working

*<html>
<head>
<title>practise</title>
<script type="text/javascript">
function confirm() {
    var r = confirm("Press the button");
    if (r == true) {
        alert("You are right");
    } else {
        alert("You are wrong");
    }
}

</script>
</head>

<body>
        <input type="button" name="submit" value="showtime" onclick="confirm()"/>
    </div>
</body>
</html>*

I want to know what's the problem. It is not working but it is the same as in http://www.w3schools.com/js/js_popup.asp

Solution

You are recursively calling confirm() and it's in an infinite loop
You have a * at the beginning and end of the document
As kennebec pointed out, you're overwriting window.confirm
You have a hanging end </div> in the <body>

            if (r == true) {
               alert("You are right");
            } else {
               alert("You are wrong");
