如何根据键：值对从数组中删除对象？

Question

Lets say I have this array of objects:

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

Can I remove an object from that array based on a key value pair? For example remove object with name: "John"?

Answer 1

You can splice the object containing the name "John"

 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

You can also use reject :

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