Assembling commodity attributes and corresponding optional parameter array data

1 vararr = [{2"id": 1,3"Name": "Memory",4"Sid": 1,5"Sname": "16G"6 }, {7"id": 1,8"Name": "Memory",9"Sid": 2,Ten"Sname": "32G" One }, { A"ID": 2, -"Name": "Color", -"Sid": 5, the"Sname": "White" - }, { -"ID": 2, -"Name": "Color", +"Sid": 6, -"Sname": "Gold" + }, { A"ID": 2, at"Name": "Color", -"Sid": 7, -"Sname": "Yellow" -}];

Today do mall backstage management system, the background to pass over the format of data. Presumably, a property of a commodity, such as "memory", corresponds to n specific values. I need to assemble the data into the following format:

{    "1": {        "id": "1",        "Name": "Memory",        "Res": [{            "id": 1,            "Name": "Memory",            "Sid": 1,            "Sname": "16G"        }, {            "id": 1,            "Name": "Memory",            "Sid": 2,            "Sname": "32G"        }]    },    "2": {        "id": "2",        "Name": "Color",        "Res": [{            "ID": 2,            "Name": "Color",            "Sid": 5,            "Sname": "White"        }, {            "ID": 2,            "Name": "Color",            "Sid": 6,            "Sname": "Gold"        }, {            "ID": 2,            "Name": "Color",            "Sid": 7,            "Sname": "Yellow"        }]    }}

This allows me to iterate through the array data in the Res property of each property in the for-in traversal of the large object, and finally each row shows data in the format "color: white, gold, yellow".

Recently the brain is not enough, and finally under the guidance of the manager, successfully wrote out, the method is as follows:

varOutobj = {}; for(vari = 0, len = arr.length; i < Len; i++) {    varTMP =Arr[i]; if(!Outobj.hasownproperty (tmp.sku_param_id)) {outobj[tmp.sku_param_id]= {}; varInobj = {}; varInarr = []; inobj["id"] =tmp.sku_param_id; inobj["Name"] =Tmp.param_web_name;        Inarr.push (TMP); inobj["res"] =Inarr; OUTOBJ[TMP.SKU_PARAM_ID]=Inobj; } Else {        varInobj =outobj[tmp.sku_param_id]; varInarr = inobj["res"];        Inarr.push (TMP); inobj["res"] =Inarr; }}
