JSON Question

Add data to JSONObject

I'm trying to figure out how to add the following data to my json object. Could someone show me how to do this.

Website Example

$(document).ready(function() {
$('#example').dataTable( {
"aoColumnDefs": [
{ "aDataSort": [ 0, 1 ], "aTargets": [ 0 ] },
{ "aDataSort": [ 1, 0 ], "aTargets": [ 1 ] },
{ "aDataSort": [ 2, 3, 4 ], "aTargets": [ 2 ] }
]
} );
} );


My JSONObject that needs to incorporate the above example.

JSONObject json = new JSONObject();
json.put("aoColumnDefs", );

Answer

In order to have this result:

{"aoColumnDefs":[{"aTargets":[0],"aDataSort":[0,1]},{"aTargets":[1],"aDataSort":[1,0]},{"aTargets":[2],"aDataSort":[2,3,4]}]}

that holds the same data as:

  {
    "aoColumnDefs": [
     { "aDataSort": [ 0, 1 ], "aTargets": [ 0 ] },
     { "aDataSort": [ 1, 0 ], "aTargets": [ 1 ] },
     { "aDataSort": [ 2, 3, 4 ], "aTargets": [ 2 ] }
   ]
  }

you could use this code:

    JSONObject jo = new JSONObject();
    Collection<JSONObject> items = new ArrayList<JSONObject>();

    JSONObject item1 = new JSONObject();
    item1.put("aDataSort", new JSONArray(0, 1));
    item1.put("aTargets", new JSONArray(0));
    items.add(item1);
    JSONObject item2 = new JSONObject();
    item2.put("aDataSort", new JSONArray(1, 0));
    item2.put("aTargets", new JSONArray(1));
    items.add(item2);
    JSONObject item3 = new JSONObject();
    item3.put("aDataSort", new JSONArray(2, 3, 4));
    item3.put("aTargets", new JSONArray(2));
    items.add(item3);

    jo.put("aoColumnDefs", new JSONArray(items));

    System.out.println(jo.toString());
