Order JSON data by month in a chronological manner

My current json data is disordered and needs to be converted into a better format resembling the "expected" JSON object. The months are not in order which makes it difficult to filter out accordingly in the DOM. I require a complete reordering of the data like this: 2015-01, 2015-02, 2015-03...


Var myJson = [{"month":"2015-03", "name":"sg"},
              {"month":"2015-03", "name":"pi"},
              {"month":"2015-06", "name":"sg"},
              {"month":"2015-06", "name":"pi"},
              {"month":"2015-01", "name":"sg"},
              {"month":"2015-01", "name":"pi"},
              {"month":"2015-02", "name":"sg"},
              {"month":"2015-02", "name":"pi"}
             ];
var expected = [{"month":"2015-01", "name":"sg"},
              {"month":"2015-01", "name":"pi"},
              {"month":"2015-02", "name":"sg"},
              {"month":"2015-02", "name":"pi"},
              {"month":"2015-03", "name":"sg"},
              {"month":"2015-03", "name":"pi"},
              {"month":"2015-06", "name":"sg"},
              {"month":"2015-06", "name":"pi"}
             ];

Answer №1

To sort the array myJson, which contains objects with month values, you can utilize the Array.sort method in JavaScript like this:

myJson.sort(function(a, b) {
  return a.month > b.month;
});

By using this code snippet, you will be able to arrange the array according to your desired order.

Keep in mind that this sorting is based on string values and not numerical ones. For more accurate results, it is recommended to split the month values by "-" and then convert them into integers using parseInt. After parsing the month and year values separately, you can proceed to perform a numeric sorting operation based on year and month as per your requirements.
