Question

我有2个数组，我想组合两个数组，这将导致第三个数组，就像在第二个图像中一样。我怎么能这样做？

＆＃13;

const mapper = {
  characters: {
    'onepiece': {
      'luffy': 'pirate king',
      'sanji': 'cook'
    },
    'deathnote': {
      'ryuk': 'shinigami',
      'lee': 'weirdo :)'
    }
  },
  animes: {
    'onepiece': 'one piece',
    'deathnote': 'death note'
  }
}

＆＃13;

我想得到这样的结果：

＆＃39;路飞：海贼王海贼王＆＃39;，
＆＃39; Sanji：海贼王烹制＆＃39;，
＆＃39; Ryuk：死亡笔记中的Shinigami＆＃39;，
＆＃39; Lee：Weirdo :) in Death Note＆＃39;

Answer 1

Javascript实施

const mapper = {
  characters: {
    'onepiece': {
      'luffy': 'pirate king',
      'sanji': 'cook',
    },
    'deathnote': {
      'ryuk': 'shinigami',
      'lee': 'weirdo :)',
    },
  },
  animes: {
    'onepiece': 'one piece',
    'deathnote': 'death note',
  },
};

const result = Object.assign({}, mapper.characters.onepiece, mapper.characters.deathnote);
console.log(result);

Answer 2

您可以为此嵌套经典 for / in循环。

＆＃13;

const mapper = {
  characters: {
    'onepiece': {
      'luffy': 'pirate king',
      'sanji': 'cook'
    },
    'deathnote': {
      'ryuk': 'shinigami',
      'lee': 'weirdo :)'
    }
  },
  animes: {
    'onepiece': 'one piece',
    'deathnote': 'death note'
  }
};


let result = [];
for (var key in mapper.characters) {
  for (var key2 in mapper.characters[key]) {
    result.push(jsUcfirst(key2) + " : " + jsUcfirst(mapper.characters[key][key2]) + " in " + jsUcfirst(mapper.animes[key]));
  }
}

//Capitalize first letter of each word on a string
function jsUcfirst(string) {
  let arr = [];
  string = string.split(" ");
  for (var key in string) arr.push(string[key].charAt(0).toUpperCase() + string[key].slice(1));
  return arr.join(" ");
}

console.log(result);
