对象数组去重

对象数组去重

直接看代码，不多解释

let objArray = [
  { value: '1', lable: '1xxx' },
  { value: '1', lable: '1xxx' },
  { value: '2', lable: '2xxx' },
  { value: '2', lable: '2xxx' },
  { value: '3', lable: '3xxx' },
  { value: '3', lable: '3xxx' },
  { value: '3', lable: '3xxx' },
  {value: '4',lable: '4xxx'},
  {value: '4',lable: '4xxx'},
];

const unique = (arr, atter) => { 
  const res = new Map();
  return arr.filter((arr)=> !res.has(arr[atter]) && res.set(arr[atter],1))
}
//                 数组名，要去重的对象属性
console.log(unique(objArray,"value"))

//

[
{ value: '1', lable: '1xxx' },
{ value: '2', lable: '2xxx' },
{ value: '3', lable: '3xxx' },
{ value: '4', lable: '4xxx' }
]
