find the leap year by using for loop

You don't need for loop to determine if leap year or not. Try this code I made.

Code:

<html>
<head>
<title>Zick Sample</title>
<script>
function leapyear()
{
	var year = document.getElementById("inputyear").value;
	if(year != "")
	{
		if ((year % 4 == 0) && year % 100 != 0)
	    {
	        alert(year + " is a leap year.");
	    }
	    else if (year % 400 == 0)
	    {
	        alert(year + " is a leap year.");
	    }
	    else
	    {
	        alert(year + " is not a leap year.");
	    }
	}
}
</script>
</head>
<body>
<form method="post" action="javascript:;">
	<input type="text" id="inputyear" placeholder="Enter the year."><br>
	<input type="submit" value="Submit" onclick="leapyear()">
</form>
</body>
</html>

one of the best leap year calculations I found:

Code:

(new Date(year, 1, 29).getDate() === 29)
