JavaScript添加键值对的值

我有这样一个数组：

[
0:{20: 24, 30: 37, 40: 17, 50: 16, 60: 5, 70: 2, day: "1"}

20:{20: 91, 30: 170, 40: 77, 50: 45, 60: 18, 70: 2, -1: 54, day: "21"}

21:{20: 126, 30: 284, 40: 134, 50: 68, 60: 41, 80: 2, -1: 11, day: "22"}

22:{20: 101, 30: 238, 40: 100, 50: 50, 60: 29, 80: 1, -1: 5, day: "23"}

]

我想按行添加数组中的所有值 示例：0:{20:24，30:37，40:17，50:16，60:5，70:2，day:1}

剩余值也一样，并存储它们

---

101，…所有的附加值

如果这个JSON是有效的，我会尝试这样的方法

function addValues(object) {
  let total = 0
  for (const [key, value] of Object.entries(obj)) {
    total += parseInt(value)
  }
  return total
}

然后，插入对象

addValues(myArray[0])

…编辑： 我将遍历数组中的所有项，对每个对象调用addTotals并返回最终值。大概是这样的：

function() {
  let total = 0
  myArray.forEach(obj => {
    total += addValues(obj)
  })
  return total
}

在我公开时，提供JSON是有效的，您希望在另一个数组中得到结果：

var foo = [

let bar = [];
for (let i = 0; i < foo.length; i++) {
  let sum = 0;
    for (let property in foo[i]) {
    if (foo[i].hasOwnProperty(property) && property != 'day') {
        // do stuff
        sum += foo[i][property];
    }
  }
  bar.push(sum);
  console.log(bar[i]);
}

您可以使用函数reduce和map

使用每个对象的总和创建一个新数组

var数组=[{20:24,30:37,40:17,50:16,60:5,70:2，day:1}，{20:69,30:163,40:88,50:42,60:27,80:2，-1:3，day:2}，{20:78，30:220，40:88，50:49，60:22，70:1130:2，-1:9，第3天，{20:14，30:18，40:7，50:10，60:3，第4天，{20:21，30:63，40:22，50:9，60:5，-1:1，第5天}，{20:12，30:38，40:10，50:13，60:1，-1:1，日：6}，{20:23，30:39，40:21，50:5，60:1，-1:1，日：7}，{20:57，30:156，40:67，50:19，60:17，70:1，80:1，-1:5，日：8}，{20:67，30:169，40:86，50:56，60:30，-1:6，日：9}，{20:101，30:209，40:99，50:56，60:34，-1:10，日：10}，{10:1，20:108，30:223，40:134，50:60，60:40，70:3，80:2130:3，-1:10，日：11}，{10:2，20:73，30:158，40:72，50:39，60:22，-1:11，日：12}，{20:66，30:126，40:59，50:26，60:12，70:2，-1:11，日：13}，{10:1，20:36，30:85，40:34，50:10，60:11，-1:14，day:14}，{10:1，20:57，30:146，40:43，50:33，60:12，70:1，-1:4，day:15}，{20:91，30:209，40:132，50:56，60:30，70:1，80:1，-1:5，日：16}，{20:74，30:185，40:73，50:34，60:21，70:1，80:1，-1:13，日：17}，{20:78，30:208，40:101，50:41，60:34，80:1，-1:7，日：18}，{20:85，30:244，40:111，50:53，60:35，70:1，-1:13，日：19}，{20:87，30:191，40:113，50:49，60:26，70:2130:1，-1:37，日期：20}，{20:91，30:170，40:77，50:45，60:18，70:2，-1:54，日期：21}，{20:126，30:284，40:134，50:68，60:41，80:2，-1:11，日：22}，{20:101，30:238，40:100，50:50，60:29，80:1，-1:5，日：23}，{20:131，30:265，40:125，50:54，60:27，80:1，-1:12，day:24}，{20:91，30:244，40:138，50:66，60:29，70:1，80:1，130:2，-1:13，day:25}，{20:95,30:269,40:123,50:53,60:33,130:1，-1:14，第26天}，{20:110,30:221,40:83,50:42,60:23,80:2，-1:26，第27天}，{20:70，30:130，40:38，50:33，60:13，80:1，-1:2，day:28}，{20:122，30:310，40:160，50:53，60:31，80:2130:1，-1:15，day:29}，{20:91，30:204，40:97，50:59，60:21，-1:13，日：30}，{20:97，30:206，40:125，50:53，60:27，130:1，-1:16，日：31}]； var result=array.mapo=>Object.keyso.reducea，k=>a+k==day？0:o[k]，0； console.logresult； .作为控制台包装{最大高度：100%！重要；顶部：0；}和wha

这正是你的问题？这不是一个代码编写服务。尝试一些东西，并询问你有什么问题。请在这里发布之前尝试一些东西！此外，这是一个无效的JSON，其索引位于obj旁边。
