抽奖代码

// 从页面提取参与用户的函数
function getValidUsers() {
  // 获取所有回复

  // 存储有效用户(剔除重复用户和楼主)
  const validUsers = new Map();
  const op = 'yuzo555';

  replies.forEach(reply => {
    const username = reply.querySelector('strong a').textContent;
    if(username !== op && !validUsers.has(username)) {
      validUsers.set(username, true);
    }
  });

  return Array.from(validUsers.keys());
}

// 抽奖函数
function drawLuckyUsers(seeds) {
  let users = getValidUsers();
  const winners = [];

  // 使用每个种子抽取一位获奖者
  seeds.forEach(seed => {
    if(users.length === 0) return;

    // 用种子除以当前用户数取余
    const winnerIndex = seed % users.length;
    winners.push(users[winnerIndex]);

    // 移除已中奖用户,重新计算序号
    users = users.filter((_, index) => index !== winnerIndex);
  });
