json合并数据问题请教

[lihan6839]

现在有一组JSON，格式如下

[{"id":"1","stationName":"金华测试1","2017/10/11":"2017/10/11","2017/10/11values":"79"},{"id":"1","stationName":"金华测试1","2017/10/11":"2017/10/11","2017/10/11values":"88"},{"id":"1","stationName":"金华测试1","2017/10/11":"2017/10/11","2017/10/11values":"66"},{"id":"2","stationName":"金华测试1","2017/10/11":"2017/10/11","2017/10/11values":"89"}]

我想根据ID进行合并，想要变成这种格式

[{"id":"1","stationName":"金华测试1","2017/10/11":"2017/10/11","2017/10/11values":"79","2017/10/11":"2017/10/11","2017/10/11values":"88","2017/10/11":"2017/10/11","2017/10/11values":"66"},{"id":"2","stationName":"金华测试1","2017/10/11":"2017/10/11","2017/10/11values":"89"}]

没有什么头绪 希望大神解答一下 谢谢

都没看懂，是要去重复嘛？

哎，先格式化 json1: [ { "id":"1", "stationName":"金华测试1", "2017/10/11":"2017/10/11", "2017/10/11values":"79", "2017/10/11":"2017/10/11", "2017/10/11values":"88", "2017/10/11":"2017/10/11", "2017/10/11values":"66" }, { "id":"2", "stationName":"金华测试1", "2017/10/11":"2017/10/11", "2017/10/11values":"89" } ] [ { "id":"1", "stationName":"金华测试1", "2017/10/11":"2017/10/11", "2017/10/11values":"66" }, { "id":"2", "stationName":"金华测试1", "2017/10/11":"2017/10/11", "2017/10/11values":"89" } ] json2： String parse JS eval [ { "id":"1", "stationName":"金华测试1", "2017/10/11":"2017/10/11", "2017/10/11values":"79", "2017/10/11":"2017/10/11", "2017/10/11values":"88", "2017/10/11":"2017/10/11", "2017/10/11values":"66" }, { "id":"2", "stationName":"金华测试1", "2017/10/11":"2017/10/11", "2017/10/11values":"89" } ] [ { "id":"1", "stationName":"金华测试1", "2017/10/11":"2017/10/11", "2017/10/11values":"66" }, { "id":"2", "stationName":"金华测试1", "2017/10/11":"2017/10/11", "2017/10/11values":"89" } ]

发现格式化前格式化后一个样。 我猜一下你的需求，可能是把json数组中的符合id的对象的各个属性合并。 你可以这样 1、用hashmap构建一个集合 2、循环：把json中的对象一个一个解析出来。 2.1、判断hashmap中有这个对象没，有的话，取出来，把当前json中的对象的属性一个一个对，hashmap中对象有这个属性，就处理一下（替换或者合并），没有就赋值。更新hashmap中对象。 2.2、如果没有这个对象，则直接存入hashmap。 3、把hashmap中对象全部取出，另存为json。
