检查对象键具有空值

Question

我有对象＆amp;它的关键空值;

喜欢var obj = {newData : {}};

我想把if条件返回true或false。如何检查obj.newData是否有空对象？

Answer 1

const obj = {newData : {}};
const obj2 = {newData : {x: 'x'}};
const isEmpty = testObj => Object.keys(testObj).length === 0;
console.log(isEmpty(obj.newData));
console.log(isEmpty(obj2.newData));
