var aa = [    {        id: 1,        imei: '',        store_name: '合肥店'    },    {        id: 3,        imei: '3',        store_name: '合肥店'    },    {        id: 2,        imei: '1',        store_name: '芜湖店'    },    {        id: 4,        imei: '34343',        store_name: '上海店'    }];

　　

分类 一var list = aa,    flag = 0,    data = [];          for(var i = 0; i< list.length; i++) {    var az = '';    for (var j = 0; j < data.length; j++) {        if(data[j][0].store_name == list[i].store_name) {            flag = 1;            az = j;            break;        }    }    if(flag == 1){        data[az].push(list[i]);        flag = 0;    } else if (flag == 0) {        wdy = new Array();        wdy.push(list[i]);        data.push(wdy);    }}console.log(data)

　　

分类二for(var i = 0; i < list.length; i++) {    if(!data[list[i].store_name]) {        var arr = [];        arr.push(list[i]);        data[list[i].store_name] = arr;    }else {        data[list[i].store_name].push(list[i])    }}console.log(data);

　　结果如下:

分类三var moth = [],    flag = 0,    list = aa;var wdy = {    title: '',    sur_name: ''}for (var i = 0; i < list.length; i++) {    var az = '';    for (var j = 0; j < moth.length; j++) {        if (moth[j].title == list[i]['store_name']) {            flag = 1;            az = j;            break;        }    }    if (flag == 1) {        var ab = moth[az];        ab.sur_name.push(list[i]);        flag = 0;    } else if (flag == 0) {        wdy = {};        wdy.title = list[i]['store_name'];        wdy.sur_name = new Array();        wdy.sur_name.push(list[i]);        moth.push(wdy);    }}console.log(moth);
