Rearranging a Json object

Rearranging a Json object

Rearranging a Json object

I am trying to convert a json object that contains:


var dataold = [{
    "DateGroup": "05/15/2012",
    "Product": "Var1",
    "Duration": 0
    "DateGroup": "05/15/2012",
    "Product": "Var2",
    "Duration": 53.999700
    "DateGroup": "05/15/2012",
    "Product": "Var3",
    "Duration": 86.999580

to this format:


var datanew = [{
    "DateGroup": "05/15/2012",
    "var1": 0,
    "var2": 53.999700,
    "var3": 86.999580
    "DateGroup": "06/17/2012",
    "var1": 32.999880,
    "var2": 59.999700,
    "var2": 59.999700
    "DateGroup": "07/19/2012",
    "var1": 37.999880,
    "var2": 0,
    "var3": 83.999580

but am not sure how to go about parsing the object and making the necessary changes.

RE: Rearranging a Json object

it will probably be easier to do this in whatever server side software you use to generate the input. If you must do it in javascript then you will need to constuct some nested loops or tweak your structure a little bit (in which case you can probably get it done in a single loop).

RE: Rearranging a Json object

I need to do it in Javascript. I've been trying to do it with nested loops, but without much success.

RE: Rearranging a Json object

i have not tested it but something like this might work. it's not exactly the same output format, but close.


<!DOCTYPE html>

<p id="demo"></p>

var nO = {};
var oO = [{
    DateGroup: "05/15/2012",
    Product: "Var1",
    Duration: 0
    DateGroup: "05/15/2012",
    Product: "Var2",
    Duration: 53.999700
    DateGroup: "05/15/2012",
    Product: "Var3",
    Duration: 86.999580
for(var i = 0; i < oO.length; i++){ 
for(var i = 0; i < oldO.length; i++){ 
 if(!(oldO[i].DateGroup in nO))nO[oldO[i].DateGroup] = {};
 nO[oldO[i].DateGroup][oldO[i].Product] = oldO[i].Duration;
document.getElementById('demo').innerHTML = JSON.stringify(nO);

RE: Rearranging a Json object

and just in case you don't know how to retrieve the data


for(var dateGroup in nO){
 for(var Property in nO[DateGroup]){
   var Duration = nO[DateGroup][Property];
   // you now have the dategroup, the property and the duration for that property
