如何根據鍵：值對從數組中刪除對象？

Question

假設我有這個對象數組：

[{name: "John", age: "30"},
 {name: "Jane", age: "20"}]

我可以根據鍵值對從該數組中刪除一個對象嗎？ 例如刪除名稱為：“John”的對象？

Answer 1

您可以拼接包含名稱“John”的對象

 var a=[{name: "John", age: "30"}, {name: "Jane", age: "20"}]; a.forEach((e)=>{ if(e.name=="John") a.splice(a.indexOf(e),1) }) console.log(a)

Answer 2

您還可以使用reject ：

var people = [{name: "John", age: "30"},
 {name: "Jane", age: "20"}]
people = people.reject(person => person.name === "John")
