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 ?

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}]

回答

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));

可参考:

    let oldList = [{ code: 2001, name: '张三' },

{ code: 2002, name: '李四' },

{ code: 2003, name: '王五' }]

let codeAll = oldList.reduce((prev, item) => {

prev.push(item.code)

return prev

}, [])

let newList = [{ code: codeAll.join(',') }]

console.log('newList==>', newList)

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 ?

var newList = [{

code: [{code:2001,name:'张三'},{code:2002,name:'李四'},{code:2003,name:'王五'}].map(({ code }) => code).join(',')

}]
