这段代码能帮忙简化一下吗                        

                        for(let i=0;i<ajaxData.length;i++){
                            userData.key=i;
                            userData.order=i+1;                            
                            userData.nickname=ajaxData[i].userId;
                            userData.username=ajaxData[i].username;
                            userData.sex=ajaxData[i].sex;
                            userData.phone=ajaxData[i].tele;
                            userData.email=ajaxData[i].email;
                            userData.state=ajaxData[i].status;
                            for(let t=0;t<ajaxData[i].role.length;t++){
                                role.push(ajaxData[i].role[t].roleId+' ')
                            };
                            userData.select=role;
                            num=i+1;
                        };

Answer 1

ajaxData.forEach((   { userId:nickname,      username,      sex,      tele:phone,      email,      status:state,      role    }, i)=>{     userData = {     nickname, username, sex, phone, email, state,     key: i,      order: i + 1,     select: role.map(r=>`${r.roleId} `)   };   num = i + 1; })主要是你的key竟然不是相同的，要不然直接{...data}就好了。。。
