javascript - 仅当所有对象中的值为空时，才从对象数组中删除空值

Question

我正在尝试删除数组中的空字符串。

这是我的数组:

let array = [{name:'John',age:'18',address:''},{name:'George',age:'',address:''},{name:'Kevin',age:'25',address:''}]

只有在所有对象中为空时，我才想删除空字符串值。

期望的结果:

[{name:'John',age:'18'},{name:'George',age:''},{name:'Kevin',age:'25'}]

这就是我所做的，但它删除了每个空字符串值:

 for (let i = 0; i < array.length; i++) {
 array[i] = Object.fromEntries(Object.entries(array[i]).filter(([_, v]) => v != ''));
 }

提前致谢，

如果您不介意改变原始 array 对象。这是一个利用一些数组函数的解决方案。

let array = [
  { name: 'John', age: '18', address: '' },
  { name: 'George', age: '', address: '' },
  { name: 'Kevin', age: '25', address: '' }
]

Object.keys(array[0])
  .filter(k => array.every(obj => !obj[k]))
  .forEach(k => array.forEach(obj => delete obj[k]));

console.log(array);
