Serialize multiple forms together?

戏子无情 提交于 2019-11-26 19:23:12
问题 Can you serialize multiple forms into one so that only one post or ajax request is made? I have searched around and it is all for submiting each form separently via post/ajax. 回答1: When you use the jQuery serialize() function, it simply turns your form into a string in the format a=1&b=2&c=3 . So you can certainly apply this function to two forms and concatenate the result, with an & between them, and use the result in your ajax call. You'd want some checks to make sure neither string is

Unable to Loop through dynamic json string recursively in android

余生长醉 提交于 2019-11-26 18:01:59
This is my JSON String (this changes dynamically): This is one json object from the entire json string which is an array. If the JSON object has value greater than 1 for "ChildExists" (for example 4 like below), an array called "Categories" appears and 4 objects will be shown. If the childExist value of any of those objects become greater than 1, a json array called "Categories" will appear. This will happen over and over again if the object's value for "childExists" is greater than 0. I created 2 model classes for this with the following attributes : public class Menu implements Serializable{

使用 net.sf.json.JSONObject;进行JSONObject、JSONArray、Map、JavaBean的相互转换

1,JSONObject json对象,就是一个键对应一个值,使用的是大括号{ },如:{key:value} 2,JSONArray json数组,使用中括号[ ],只不过数组里面的项也是json键值对格式的 Json对象中添加的是键值对,JSONArray中添加的是Json对象 1 import net.sf.json.JSONArray; 2 import net.sf.json.JSONObject; 3 import org.junit.Test; 4 5 import java.util.ArrayList; 6 import java.util.HashMap; 7 import java.util.Iterator; 8 9 public class JsonTest { 10 11 public static void main(String[] args) { 12 //----------------JsonObject创建的方法----------------------------------------------------------- 13 //创建JsonObject第一种方法 14 JSONObject jsonObject = new JSONObject(); 15 jsonObject.put("UserName", "kobi");

convert ArrayList<MyCustomClass> to JSONArray

本秂侑毒 提交于 2019-11-26 17:09:13
I have an ArrayList that I use within an ArrayAdapter for a ListView. I need to take the items in the list and convert them to a JSONArray to send to an API. I've searched around, but haven't found anything that explains how this might work, any help would be appreciated. UPDATE - SOLUTION Here is what I ended up doing to solve the issue. Object in ArrayList: public class ListItem { private long _masterId; private String _name; private long _category; public ListItem(long masterId, String name, long category) { _masterId = masterId; _name = name; _category = category; } public JSONObject

hive 将hive表数据查询出来转为json输出

纵饮孤独 提交于 2019-11-26 16:11:25
一、思路 1、将查询出来的数据转为一行一行,并指定分割符的数据 2、使用UDF函数,将每一行数据作为string传入UDF函数中转换为json再返回 1、准备数据 2、查询出来的数据转为一行一行,并指定分割符的数据 3、准备UDF函数 package com.laotou; import org.apache.hadoop.hive.ql.exec.UDF; import org.json.JSONException; import org.json.JSONObject; /** * @Author: * @Date: 2019/8/9 */ public class HiveJsonOut extends UDF{ private String delimiter="|"; public static String evaluate(String jsonStr) throws JSONException { String[] split = jsonStr.split("|"); JSONObject result = new JSONObject(); result.put("key", split[0]); result.put("value", split[1]); return String.valueOf(result); } } 4、测试 来源: https:/

多层嵌套json类型数据解析

徘徊边缘 提交于 2019-11-26 14:47:54
前段时间写了一个多层嵌套json数据对象,费了半天劲,记录一下 前端数据类似淘宝多条件搜索,json数据类型为key-value嵌套数组 前端为ajax传值 function searfunc(arr) { //arr为查询按钮之后输出的搜索条件 console.log(arr); $.ajax({ url:'/conprob/titleList', type:'post', contentType: "application/json", traditional: true, async : true, data:JSON.stringify(arr), 后台controller层用JSONArray接收数据类型   @RequestMapping(value = "titleList",produces = "application/json;charset=UTF-8") @ResponseBody public Object titleList(@RequestBody JSONArray jsonParam){ } service层进行拆分解析 for(int i = 0;i<jsonParam.size();i++){ JSONObject jsonObject=jsonParam.getJSONObject(i); String key = jsonObject

RestTemplate 发送post请求

醉酒当歌 提交于 2019-11-26 12:21:55
springboot使用restTemplate post提交值 restTemplate post值 post提交有 FormData和Payload 两种形式: 第一种是formdata形式,在header参数里可以直接看到 payload则封装成json格式post过去,获取以后需要再解析成实体。 restTemplate post json格式 使用阿里巴巴的json包 com.alibaba.fastjson 代码demo如下: url=' http://posturl ';JSONObject postData = new JSONObject(); postData.put("shopid", 1); JSONObject json = restTemplate.postForEntity(url, postData, JSONObject.class).getBody(); 如果要使用post formdata形式则需要 使用RestTemplate发送multipart/form-data格式的数据 复制代码 String url = ' http://posturl '; MultiValueMap<String, String> map= new LinkedMultiValueMap<String, String>(); map.add("shopid",

JSON中put、accumulate、elemate的区别

孤街浪徒 提交于 2019-11-26 07:27:20
JSONObject.put():将value映射到key下,加入在JSONObject对象之前存在一个value存在key下,当前的value会替换之前的value。 JSONObject.accumulate():累计这个vlue到这个key下,这个方法同elemate()方法类似,特殊的是,如果当前已存在一个value在这个key下,那么一个JSONArray将会存储在这个key下,来保留所有累计的value,如果已存在一个JSONArray,那么当前的value就会添加到这个JSONArray中。相比之下,replace方法会替代先前的value。 JSONObject.elemate():将键/值对放在这个JSONObject对象里,如果当前value为空(null),那么如果这个key存在的话,这个key就会移除掉,如果这个key之前由value值,那么此方法就回去调用.accumulate()方法。 来源: https://www.cnblogs.com/bai123/p/11316971.html
