为了得到这个结果:
{"aoColumnDefs":[{"aTargets":[0],"aDataSort":[0,1]},{"aTargets":[1],"aDataSort":[1,0]},{"aTargets":[2],"aDataSort":[2,3,4]}]}
包含与以下相同的数据:
{
"aoColumnDefs": [
{ "aDataSort": [ 0, 1 ], "aTargets": [ 0 ] },
{ "aDataSort": [ 1, 0 ], "aTargets": [ 1 ] },
{ "aDataSort": [ 2, 3, 4 ], "aTargets": [ 2 ] }
]
}
您可以使用以下代码:
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());
