如何在nodejs中拼接数组object？

Question

I m getting following result through query in nodejs.

data = [
    {
        AValuv: 6,
        BValuv: 8928,
        CValuv: 2553
    }
];

now I through forEach how to split them in two array and push them in the to get the required result.

let name=[];
let value=[];
name=[AValuv, BValuv, CValuv]
value=[6, 8928, 2553]

Answer 1

That is pretty easy in JavaScript you can use Object.keys() and Object.values() to get the keys and the values of the object.

 data=[ { AValuv: 6, BValuv: 8928, CValuv: 2553 } ] data.forEach((elem) => { let vals = Object.values(elem); let keys = Object.keys(elem); console.log(vals) console.log(keys) })

Answer 2

You can do the following,

 let data = [{'AValuv': 6, 'BValuv': 8928, 'CValuv': 2553}] let name = []; let value = []; data.forEach(item => { Object.keys(item).forEach(key => { name.push(key); value.push(item[key]); }); }); console.log(name); console.log(value);

Answer 3

You could use Array.prototype.forEeach() once on the array, and then parse the objects with Object.entries() and use Array.prototype.forEeach() once again.

 const data = [{ AValuv: 6, BValuv: 8928, CValuv: 2553 } ]; const name = []; const value = []; data.forEach(x => Object.entries(x).forEach(([k, v]) => { name.push(k); value.push(v); }) ); console.log(name); console.log(value);

Answer 4

 data = [ { AValuv: 6, BValuv: 8928, CValuv: 2553 } ]; let name = []; let value = []; data.forEach(o => { name.push(...Object.keys(o)); value.push(...Object.values(o)); }); console.log(name, value);

Answer 5

You can write the following

 data = [ { AValuv: 6, BValuv: 8928, CValuv: 2553 } ] let name = Object.keys(data[0]) let value = Object.values(data[0])

Answer 6

Like this:

const data = [{
  AValuv: 6,
  BValuv: 8928,
  CValuv: 2553
}];


let name=[];
let value=[];

for (const [key, value] of Object.entries(data[0])) {
  name.push(key);
  value.push(value);
}
