lodash uniqWith与一组对象

Question

我有一系列的对象,如:

[{id: '123', name: 'John', someKey:'1234'}, {id: '123', name: 'John', someKey:'12345'}]

这只是一个基本的例子,数据要复杂得多,所以_.isEqual不起作用.

我该如何处理比较器？我想比较id它们是否相等.

_.uniqWith(myArray, function(something) {return something})

Answer 1

比较比较_.uniqWith()器功能中的ID 或使用_.uniqBy():

var myArray = [{
  id: '123',
  name: 'John',
  someKey: '1234'
}, {
  id: '123',
  name: 'John',
  someKey: '12345'
}]

var result = _.uniqWith(myArray, function(arrVal, othVal) {
  return arrVal.id === othVal.id;
});

console.log(result);

/** using uniqBy **/

var result = _.uniqBy(myArray, 'id');

console.log(result);
