获取list，有内容就赋值,根据ID显现NAME,没有显现list

function onTOWN() {

    var town=mini.get("TOWN_ID");

    var town_id =town.getValue();

    $.ajax({

        url:"${ctx}/aUTHDEPARTMENT/onTOWN",

        data:{"town_id":town_id},

        dataType:"json",

        async:false,

        success:function(json){

            town.setData(json);

        }

    })

}

java代码

List<Record> list = Db.find("SELECT * FROM AUTH_DEPARTMENT WHERE DEPARTMENT_LEVEL='2'");

if(list!=null){

    for(Record re:list){

        Map a = new HashMap();

        a.put("id", re.get("ID"));

        a.put("text", re.get("NAME"));

        STATEList.add(a);

    }

}

renderJson(STATEList);
