循环拼接以更新新的对象数组

Question

let index = findIndex(existingObjs, { '_id': data.id });
if (index > -1) {
    existingObjs.splice( index, 1, newObj );
}

Above code is working to replace updated obj after a PUT. But I have problem doing so if the newObj is an array and has multiple object.

Answer 1

From what it seems you are trying to remove one and add multiple objects from the obj array newObj , you can do that using the spread operator .

Do it in the following manner

let index = findIndex(existingObjs, { '_id': data.id });
if (index > -1) {
    existingObjs.splice( index, 1, ...newObj );
}
