怎么将json 对象的里面的value 值 形成一个新的对象json对象 然后传给后端 ？

Question

例如：
源数据：let oldList=[{code:2001,name:张三，}{code:2002,name:李四，
},{code:2003,name:王五，}]

期望得到： let newList=[{code:2001,2002,2003}]

Answer 1

let oldList=[{code:2001,name:'张三'},{code:2002,name:'李四'},{code:2003,name:'王五'}]

const list = oldList.map(item => { return { code: item.code } });

console.log(JSON.stringify(list));
