我有一個數組，我想將此數組轉換為單獨的對象，很高興幫助我，謝謝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] }]

首先找出數組中字符串的索引，以便可以拆分數組。

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));
