如何遍历对象数组并从对象中获取值-ES6

Question

I need to loop over this and add this to form data.

"SHOCKS" = [{
  $type: "Scenar",
  CCY_PAIR: "GBPUSD",
  D0: 0.3,
  D1: 0.3,
  …
}, {
  $type: "Scenar",
  CCY_PAIR: "KRWUSD",
  D0: 0.3,
  D1: 0.3,
  …
}, {
  $type: "Scenar",
  CCY_PAIR: "AUDJPY",
  D0: 0.08,
  D1: 0.08,
  …
} {
  $type: "Scenar",
  CCY_PAIR: "AUDKRW",
  D0: 0.08,
  D1: 0.08,
  …
}, {
  $type: "Scenar",
  CCY_PAIR: "AUDMXN",
  D0: 0.08,
  D1: 0.08,
  …
}],

I'm doing like below.

let FxShock = FxList["FXVOLBUMP"].SHOCKS;
let FxShocksAll1 = Object.entries(FxShock).forEach(([key, value]) => console.log(`${key}: ${value}`));

But I'm getting undefined .

Loop through the array, and then through the key -> value pairs of each object:

 let SHOCKS = [{ $type: "Scenar", CCY_PAIR: "GBPUSD", D0: 0.3, D1: 0.3, }, { $type: "Scenar", CCY_PAIR: "KRWUSD", D0: 0.3, D1: 0.3, }, { $type: "Scenar", CCY_PAIR: "AUDJPY", D0: 0.08, D1: 0.08, }, { $type: "Scenar", CCY_PAIR: "AUDKRW", D0: 0.08, D1: 0.08, }, { $type: "Scenar", CCY_PAIR: "AUDMXN", D0: 0.08, D1: 0.08, }]; SHOCKS.forEach((obj, idx) => { console.log("object " + (idx + 1)); for (var key in obj) { if (obj.hasOwnProperty(key)) { console.log(key + " -> " + obj[key]); } } });
