如果对象的所有属性为空，则从对象数组中删除对象

Question

我有一个对象数组，其中每个对象都有某些属性。我想从数组中删除为对象内所有属性分配了空字符串的对象。

示例：

var x = [{
   "userName" : "XYZ",
   "age": 22,
   "gender": "M"
}, {
   "userName" : "ABC",
   "age": 23,
   "gender": "M"
}, {
   "userName" : "Mohan",
   "age":"",
   "gender": ""
}, {
   "userName" : "",
   "age":"",
   "gender": ""
}]

结果应为

[{
   "userName" : "XYZ",
   "age": 22,
   "gender": "M"
}, {
   "userName" : "ABC",
   "age": 23,
   "gender": "M"
}, {
   "userName" : "Mohan",
   "age":"",
   "gender": ""
}]

Answer 1

您可以结合使用filter，every和Object.values：

const x = [{
   "userName" : "XYZ",
   "age": 22,
   "gender": "M"
}, {
   "userName" : "ABC",
   "age": 23,
   "gender": "M"
}, {
   "userName" : "Mohan",
   "age":"",
   "gender": ""
}, {
   "userName" : "",
   "age":"",
   "gender": ""
}]

const y = x.filter(z => !Object.values(z).every(w => w ===""))

console.log(y)
