<!DOCTYPE html>
<html>
<head>
	<title>数字随机生成器</title>
	<meta charset="UTF-8">
	<meta name="viewport" content="width=device-width, initial-scale=1.0">

<body>
	<h1>数字随机生成器</h1>
	<p>请点击下面的按钮随机生成6个数字：</p>
	<button onclick="generate()">生成</button>
	<p id="result"></p>
	<script>
		function generate() {
			var numbers = [];
			while (numbers.length < 6) {
				var number = Math.floor(Math.random() * 33) + 1;
				if (!numbers.includes(number)) {
					numbers.push(number);
				}
			}
			document.getElementById("result").innerHTML = numbers.join(", ");
		}
	</script>
</body>
