将数组的某些元素排序为其他数组

将数组的某些元素排序为其他数组

对于项目，我必须对包含字符串和数字的数组进行排序。该字符串用作将数字存储到哪个数组的指示符。

let myArray = [22, 'talk', 31, 'perfo', 35, 'init', 42, 'talk']
let talk = []
let perfo = []
let init = []

for (let i = 0; i < myArray.length; i + 2) {
    if (myArray[i + 1] == 'talk') {
        talk.push(myArray[i])
    } else if (myArray[i + 1] == 'perfo') {
        perfo.push(myArray[i])
    } else if (myArray[i + 1] == 'init') {
        init.push(myArray[i])
    } else {}
}

预期结果：

talk [22, 42], perfo [35], init [42]

但是不知何故它似乎不适合for循环。

回答如下：

您可以将所需数组作为对象，然后将值压入该对象。

let data = [22, 'talk', 31, 'perfo', 35, 'init', 42, 'talk'],
    talk = [],
    perfo = [],
    init = [],
    temp = { talk, perfo, init },
    i = 0;

while (i < data.length) {
    let [value, key] = data.slice(i, i += 2);
    temp[key].push(value);
}

console.log(talk);
console.log(perfo);
console.log(init);
