如何基于数组随机值实现网站跳转？

首先你需要建立城市与对应目标网址的映射关系，用对象存储是最直观的方式，之后就能根据随机选中的城市，取出对应的网址完成跳转。修改后的代码如下：

// 建立城市和对应网址的键值对映射
const cityUrls = {
  "Bhutan": "https://example.com/bhutan",
  "London": "https://example.com/london",
  "Paris": "https://example.com/paris",
  "Dubai": "https://example.com/dubai",
  "New York City": "https://example.com/new-york",
  "Singapore": "https://example.com/singapore"
};

// 获取所有城市名称的数组
const cities = Object.keys(cityUrls);
// 随机选中一个城市
const selectedCity = cities[Math.floor(Math.random() * cities.length)];

function myCities() {
  // 根据选中的城市匹配对应网址
  const targetUrl = cityUrls[selectedCity];
  // 确认网址存在后跳转，避免无对应值的错误
  if (targetUrl) {
    location.assign(targetUrl);
  }
}

补充说明： #

• 用对象存储映射比单独的城市数组更易维护，能直接关联城市和网址
• 如果你需要每次调用myCities函数时都重新随机选择城市，把随机逻辑移到函数内部即可：

const cityUrls = {
  "Bhutan": "https://example.com/bhutan",
  "London": "https://example.com/london",
  "Paris": "https://example.com/paris",
  "Dubai": "https://example.com/dubai",
  "New York City": "https://example.com/new-york",
  "Singapore": "https://example.com/singapore"
};

function myCities() {
  const cities = Object.keys(cityUrls);
  const selectedCity = cities[Math.floor(Math.random() * cities.length)];
  const targetUrl = cityUrls[selectedCity];
  if (targetUrl) {
    location.assign(targetUrl);
  }
}
