这是公司年会抽奖的一个程序，其中特等奖，1等奖，2等奖设置了12个空格符占位，目的是为了让刚到不久的员工排除在外，又不让他们看到，怎么让程序不抽到这12个空格，请教了一个6年的老司机，没搞定，哪位前端大神帮忙看下，按空格键执行程序，谢谢

正常逻辑不应该是直接抽出中奖的号码吗，跑马灯什么的只是前端的展示效果而已，实际上在轮转的时候中奖号码早就确定了才对
最简单的思路,如果命中到''了,就再递归执行一次抽奖方法,直到非''的号命中为止.理论上有几毫秒的延迟,实际上人类是无法感知的.
实话讲,你这代码看得太累了,不是很方便调整,只能简单列下.
我大致了解题主的思路了.
用两个数组去存就可以了:
抽前三个的时候 以secMember去抽, 同时修改其中奖状态, 以及
allMember中对应那个人的isGolded补充说明:
首页的显示中奖信息的, 遍历allMember即可, 判断是否已经中过奖(isGolded);
抽奖顺序任意, 只要考虑当前要抽的奖项是 部分人secMember 还是所有人allMember,
抽奖时, 先filter出未中奖的人(评论中给出了方法). 然后随机抽取.
选人结束后 同时修改其在 secMember 和 allMember中对应的isGolded字段为true.
跑马灯不是可以指定抽奖位号吗，比如排除2，4后的1，3，5，然后你随机数的时候就在这几个里边随机就好了。
终于知道宝宝年会为什么总是抽不到奖了，每次都从我身边滑过，泪牛满面。
这想法有问题啊
前端的代码随便看了，要是不想让他们看到，得借助后端了吧
如果不能让别人看到得结合后端来写了啊...
中奖号码本来就是后端搞定的，前端就只是负责展示效果而已，最多加点特效之类的。
之前也做了公司的一个年会抽奖的展示的页面，号码之类的根本就没前端啥事，都是通过数据请求从后端来的。
到时候年会的时候现场解析代码就爽了。非要做这种奇葩事
