javascript - 比较两个列表并将一个列表值更新为其他 angular5

Question

我有两个对象列表

list 1: 总雇主-

 [{EmployerId: 1,Name:"Rick", Checked :false}, {EmployerId: 2,Name:"John", Checked :false},{EmployerId: 3,Name:"Maddy", Checked :false}]

list 2: 更新雇主

[{EmployerId: 1,Name:"Rick"},{EmployerId: 2,Name:"John"}]

如何根据list2中的记录将list1的checked值更新为true

最终输出:

list 1: 总雇主-

[{EmployerId: 1,Name:"Rick", Checked :true}, {EmployerId: 2,Name:"John", Checked :true},{EmployerId: 3,Name:"Maddy", Checked :false}]

Answer 1

这可能是最紧凑的代码:

TotalEmployers.forEach(x => {
   x.Checked = UpdatedEmployer.some(y => y.EmployerId === x.EmployerId);
});
