Answer 1

亲测可以，只要给的数据按姓名排好            var emm=[];var k=0;var msl = oarr[0].name;             $.each(oarr,function(i,j){                if(i){                    if(msl!=j.name) k++;                 }                  if(!emm[k]){                     emm[k]={};                                      }                                  emm[k]['name']=j.name;                if(!emm[k]['info']) {                     emm[k]['info']=[];                 }                delete j.name;                 emm[k]['info'].push(j);                              })                 console.log(emm)
