循环

let arr = [
                {
                    name: {
                        cun: 'name',
                        val: 123
                    },
                    id: {
                        cun: 'id',
                        val: 234
                    }
                },
                {
                    name: {
                        cun: 'name',
                        val: 111
                    },
                    id: {
                        cun: 'id',
                        val: 222
                    }
                }
            ]
            let arr2 = []
            arr.forEach(item=>{
                const obj = {}
                for(let i in item){
                    obj[item[i].cun] = item[i].val
                }
                arr2.push(obj)
            })
            console.log(arr2)
