js实现按座位号抽奖

Posted in Javascript onApril 05, 2017

最近一个项目需要实现一个按座位号抽奖的效果，抽奖现场有多个区域，抽奖时随机选取其中一个区域，再在这个区域中随机选取一排，最后在这排中随机选取一个座位号，区域、排号及座位号都不固定。

实现思路如下：

<!DOCTYPE html>
<html lang="zh-CN">
<head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <title>抽奖</title>
</head>
<body>
  <p id="result"></p>
  <script>
    // 获取两个数之间的随机数
    function getRandom(min, max){
      var num = min + Math.floor(Math.random() * (max - min + 1));
      return num;
    }

    // 列举可以参加抽奖的座位号（第几区，第几排，第几列）
    var obj = {
      '001': [
        [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12],
        [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12],
        [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12],
