const shortCode = {
  DA: ['934', '986', '879'],
  BA: ['914', '926', '849'],
  AD: ['911', '900', '899']
};


如何在该短代码对象上获取密钥。假设我有“ 879”值并搜索对应的密钥?

用Java语言编写。

最佳答案

您可以在findObject.keys上使用shortCode



const shortCode = {
  DA: ['934', '986', '879'],
  BA: ['914', '926', '849'],
  AD: ['911', '900', '899']
};

const res = Object.keys(shortCode)
                  .find(k => shortCode[k].includes('879'));

console.log(res);
