将数组转换为单独的对象数组

Question

我有一个数组，我想将此数组转换为单独的对象，很高兴帮助我，谢谢array = ["January", 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, "February", 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29]我想result  = [   {     month:'January',     days:[ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31]   },   {     month:'February',     days:[ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29]   }]

Answer 1

    首先找出数组中字符串的索引，以便可以拆分数组。

const process = (arr) => {

  const result = [];

  let last = -1;

  for (let i = 0; i <= arr.length; i++) {

    if (typeof arr[i] === "string" || !(i in arr)) {

      if (last !== -1) {

        result.push([last, i]);

      }

      last = i;

    }

  }

  return result.map(([start, end]) => ({

    month: arr[start],

    days: arr.slice(start + 1, end),

  }));

};

const array = ["January", 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, "February", 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29]

console.log(process(array));
