Type Conversion in Java and JS (Jsonarray, JsonObject, JSON)

1, Java List <map <string, object >> Type Corresponding to the object array in JS

<%@page import="net.sf.json.JSONArray"%>
List<Map<String, Object>> dataList = xxxxx;
// js code
var allCollectedRecords =<%=JSONArray.fromObject(dataList)%>;   // [{"OID":"12345","NAME":"test"},{"OID":"659","NAME":"yuwang"}]
var refMap = <%=JSONArray.fromObject(dataList).getJSONObject(0)%>;
var OID = refMap["OID"];

2, JSON character string turn object in Java

import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;

String data = (String)params.get("data");    // "[{\"OID\":\"12345\",\"NAME\":\"test\"},{\"OID\":\"659\",\"NAME\":\"yuwang\"}]"
JSONArray jsonArray=JSON.parseArray(data);
JSONObject partObj = jsonArray.getJSONObject(0);
String partOid = (String) partObj.get("OID");

3, JS object turns JSON string

var obj = {"name":"test", "site":"aaaaa"}
var str = JSON.stringify(obj);
alert(str);
