JavaScript更新多个对象属性

Question

I have this code below that finds the index of specific object using findIndex method and Update object's name property. Is there anyway i can update mutiple object's name property? Eg

var rofl = ["0"]; 

// Instead of ["0"] how do i update multiple object by putting var rofl = ["1","2","3"];

let myArray = [
  {id: 0, name: "Jhon"},
  {id: 1, name: "Sara"},
  {id: 2, name: "Domnic"},
  {id: 3, name: "Bravo"}
],

objIndex = myArray.findIndex((obj => obj.id == rofl));

console.log("Before update: ", myArray[objIndex]) // {id: 0, name: "Jhon"}

myArray[objIndex].name = ("Jerry");

console.log("After update: ", myArray[objIndex]) // {id: 0, name: "Jerry"}

Answer 1

Use forEach instead:

 const myArray = [ {id: 0, name: "Jhon"}, {id: 1, name: "Sara"}, {id: 2, name: "Domnic"}, {id: 3, name: "Bravo"} ]; ["1","2","3"].forEach(findId => myArray.find(({ id }) => id == findId).name = 'Jerry' ); console.log(myArray); 

If the IDs have a chance of not existing in the array, you'll have to add a test for that as well:

 const myArray = [ {id: 0, name: "Jhon"}, {id: 1, name: "Sara"}, {id: 2, name: "Domnic"}, {id: 3, name: "Bravo"} ]; ["1","2","3", "10"].forEach(findId => { const foundObj = myArray.find(({ id }) => id == findId); if (foundObj) foundObj.name = 'Jerry'; }); console.log(myArray); 

Answer 2

Use Array.forEach

 let myArray = [{id: 0, name: "Jhon"},{id: 1, name: "Sara"},{id: 2, name: "Domnic"},{id: 3, name: "Bravo"}]; let rofl = ["1","2","3"]; myArray.forEach((obj) => {if(rofl.includes(obj.id.toString())) obj.name = 'Jerry'}) console.log(myArray);
