工具介绍
名单粘进左边，点一下就能抽人。默认开启不重复，抽过的人不会再出现，适合一节课把全班点一遍；关掉之后就是纯粹的随机抽奖，同一个人可能连续中。 Paste the list on the left and press draw. No-repeat is on by default so nobody appears twice — good for calling on a whole class; turn it off for a plain draw where the same name can win twice.
每轮结果都会记在右边，带轮次编号，方便事后核对。名单里的重复名字不会被去重，等于变相提高了权重。 Every round is recorded on the right with a round number for later checking. Repeated names in the list are not deduplicated, which effectively raises their weight.

常见问题
抽签公平吗？Is the draw fair?
用浏览器的加密安全随机源打乱顺序后取前几位，没有隐藏权重；名单里重复写同一个名字会提高概率。It shuffles with the browser’s secure random source and takes the first entries, with no hidden weights; writing a name twice raises its chance.
不重复抽完了怎么办？What happens when no-repeat runs out?
会提示名单已抽完，点重置记录即可恢复完整名单，历史也会一并清空。It says everyone has been drawn; reset the record to restore the full list, which also clears the history.
刷新页面名单还在吗？Does the list survive a refresh?
不在，工具不写入本地存储，刷新后回到默认示例名单。No, nothing is stored locally — a refresh restores the default sample list.
可以按权重抽吗？Can I use weights?
没有单独的权重输入，需要提高某人的概率就把他多写几行。There is no weight field; add extra lines for the name that should have a higher chance.
