let rows = function1();

rows 看起来像:

"rows": [
    {
    "Hostname": "abc123",
    "name": "name1",
    "Status": "PASS",
    "Heading": "Not Applicable"
    },
    {
    "Hostname": "abc123",
    "name": "name2",
    "Status": "FAIL",
    "Heading": "Not Applicable"
    }
]

排 可以有任意数量的Json元素:

"rows": [
    {
    "Hostname": "abc123",
    "name": "name1",
    "Status": "PASS",
    "Heading": "Not Applicable"
    },
    {
    "Hostname": "abc123",
    "name": "name2",
    "Status": "FAIL",
    "Heading": "Not Applicable"
    },
    {
    "Hostname": "abc123",
    "name": "name3",
    "Status": "FAIL",
    "Heading": "Not Applicable"
    },
 ...
]

Hostname 会留下名字,

我想修改 rows array

"rows": [
    {
    "Hostname": "abc123",
    "name1Status": "PASS",
    "name1Heading": "Not Applicable"
    "name2Status": "FAIL",
    "name2Heading": "Not Applicable"
    "name3Status": "FAIL",
    "name3Heading": "Not Applicable"
     ...
]

如果你理解正确,那么你需要达到这个结果。为此使用reduce,使用数组非常方便

const rows = [
    {
    "Hostname": "abc123",
    "name": "name1",
    "Status": "PASS",
    "Heading": "Not Applicable"
    },
    {
    "Hostname": "abc123",
    "name": "name2",
    "Status": "FAIL",
    "Heading": "Not Applicable"
    }
]
const res = rows.reduce((acc, rec) => {
	let result = { ...acc, [`Hostname`]: rec.Hostname,  [`${rec.name}Status`]: rec.Status, [`${rec.name}Heading`]: rec.Heading  }
	return result
}, [])
console.log(res)
