javascript - 从包含特定关键字的 json 数据中删除所有对象

Question

我只是在寻找从包含特定术语/关键字的 json 数据中移除所有对象的最佳实践。

我的 json 数据是这样的

json = [{
 "name":"John",
 "age":30,
 "cars":"BMW"
},
{
 "name":"Micheal",
 "age":30,
 "cars":"Ford,BMW"
},
{
 "name":"Andy",
 "age":29,
 "cars":"Ford"
},
{
 "name":"Andy",
 "age":29,
 "cars":"Ford,Toyota"
}];

我想删除具有关键字“BMW”的对象。

Answer 1

您可以简单地使用Array.filter():

var arr = [{ "name":"John", "age":30, "cars":"BMW" }, { "name":"Micheal", "age":30, "cars":"Ford,BMW" }, { "name":"Andy", "age":29, "cars":"Ford" }, { "name":"Andy", "age":29, "cars":"Ford,Toyota" }];

var result = arr.filter(({cars})=> !cars.includes("BMW"));

console.log(result);
