将值从不同的数组推送到不同的键

Question

我有 2 个这样的数组：

let payrollname = [{"code": "a1", "name": "Loan A"}, {"code": "a2", "name": "Loan B"}, {"code": "a3", "name": "Loan C"}, {"code": "a4", "name": "Loan D"}, {"code": "a5", "name": "Loan E"}]

和

let payrollbalance = [{"a1": 0, "a2": 100000, "a3": 500000, "a4": 300000, "a5": 45900}]

如何将值从 payrollbalance 推送到 payrollname？

我的意思是像这样推送，来自 payrollbalance.a4 的值意味着 300000 推送到 payrollname.code == a4

我希望最后的结果能像这样：

let result = `[{"code": "a1", "name": "Loan A", "values": 0}, {"code": "a2", "name": "Loan B", , "values": 100000}, {"code": "a3", "name": "Loan C", "values": 500000}, {"code": "a4", "name": "Loan D", "values": 300000}, {"code": "a5", "name": "Loan E",  "values": 45900}]`

我们会提供任何帮助，我已经搞砸了一整天了。

提前致谢

Answer 1

使用 Array.map() 并添加值为 payrollbalance[0] 的 values 键，并通过 [] 为动态指示 json 键。

let payrollname = [{"code": "a1", "name": "Loan A"}, {"code": "a2", "name": "Loan B"}, {"code": "a3", "name": "Loan C"}, {"code": "a4", "name": "Loan D"}, {"code": "a5", "name": "Loan E"}]

let payrollbalance = [{"a1": 0, "a2": 100000, "a3": 500000, "a4": 300000, "a5": 45900}]

let result = payrollname.map(item => ({
  ...item,
  values: payrollbalance[0][item.code]
}));

console.log(result);

Answer 2

做一个array seach，找到索引后改

let payrollname = [{"code": "a1", "name": "Loan A"}, {"code": "a2", "name": "Loan B"}, {"code": "a3", "name": "Loan C"}, {"code": "a4", "name": "Loan D"}, {"code": "a5", "name": "Loan E"}]
let payrollbalance = [{"a1": 0, "a2": 100000, "a3": 500000, "a4": 300000, "a5": 45900}]
var result = [];
let pblance = payrollbalance[0]
for(let p in pblance)
{
  let index = payrollname.findIndex(el => el.code==p)
  let pname = payrollname[index]
  pname.values = pblance[p];
  result.push(pname)
}
console.log(result);

Answer 3

此代码可以工作！

let payrollname = [{"code": "a1", "name": "Loan A"}, {"code": "a2", "name": "Loan B"}, {"code": "a3", "name": "Loan C"}, {"code": "a4", "name": "Loan D"}, {"code": "a5", "name": "Loan E"}]
let payrollbalance = [{"a1": 0, "a2": 100000, "a3": 500000, "a4": 300000, "a5": 45900}]
let result = []
let i = 0
payrollname.forEach(element => {
    let value = payrollbalance[0][element.code]
    element.values = value;
    result[i] = element
    i=i+1
});
console.log(result)
