如题，不废话了，直接代码走起

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title></title>
		<script language="javascript">
			window.onload = function() {
				var arr = ["1", "2", "3", "4", "5", "6", "7", "8", "9"]
				for(var i = 0; i <= 10; i++) {
					var index = Math.floor((Math.random() * arr.length));
					document.write(arr[index] + ",");
				}
			}
		</script>
	</head>
	<body>
	</body>
</html>
