ajax json struts2
1 前台通过jquery 与struts2 action 交互$.ajax({
url: "<%=rootPath%>/index!comInitGroupEdit.action?groupId="+groupId,
type:"post",
dataType:"json",
success: function(json){
var allGroupArray = json.allGroupArray;
var groupByIdArray = json.groupByIdArray;
$.each(allGroupArray, function(i){
//window.alert("groupByIdArray.PARID: "+groupByIdArray.PARID+ "allGroupArray.ID: "+allGroupArray.ID);
if(groupByIdArray.PARID==allGroupArray.ID){
tempHTML1=" <optionselected value="+ allGroupArray.ID+ ">"+allGroupArray.NAME ;
}else{
tempHTML1=" <option value="+ allGroupArray.ID+ ">"+allGroupArray.NAME ;
}
});
$("#groupName").val(groupByIdArray.NAME);
$("#oldGroupName").val(groupByIdArray.NAME);
}
});
2 后天通过struts2 action 取数据
publicString comInitGroupEdit(){
String queryAllGroup =" SELECT tg.group_id ID,tg.group_name NAME FROM tb_iap_tgt_grouptg ORDER BY tg.group_id ASC";
String queryGroupById ="SELECT tg.group_id ID ,tg.group_id_parent parId ,tg.group_name NAME FROM tb_iap_tgt_grouptg WHERE tg.group_id="+groupId;
Map<String,Object> map = new HashMap<String, Object>();
map.put("querySql",queryAllGroup);
List<Map<String,Object>> results = indexService.getCommonQuery("getCommonQuery",map);
JSONArray allGroupArray=JSONArray.fromObject(results);
jsonObject.put("allGroupArray", allGroupArray);
map.put("querySql",queryGroupById);
results = indexService.getCommonQuery("getCommonQuery",map);
JSONArray groupByIdArray=JSONArray.fromObject(results);
jsonObject.put("groupByIdArray", groupByIdArray);
return "jsonObject";
}
