You need to convert your first JSON string to object and add a new property to it.

您需要将第一个 JSON 字符串转换为对象并向其添加新属性。

If it is Java, you can use Google's Gsonlibrary

如果是Java，可以使用谷歌的Gson库

Gson gson = new Gson();
JsonObject jsonObj = gson.fromJson (jsonStr, JsonElement.class).getAsJsonObject();
jsonObj.add("criterias", "Location");

If it is JavaScript,

如果是 JavaScript，

var jObj = JSON.parse(jsonString);
jObj.criterias = "Location";  //jObj.NewItem = "NewValue";

I believe the original question is how to merge these 2 JSON objects within javascript. Assuming that, the answer is simple.

我相信最初的问题是如何在 javascript 中合并这 2 个 JSON 对象。假设，答案很简单。

var firstJson = {  
  "categoryId":"Painting",  
  "subCategoryId":"Residential",  
  "alternatives":    [1,2,3,4,5],  
  "criterias":["price","quantity","yom","company"],  
  "answerss":[["1000","12343","4543","","4645646"],["12","23","34","","45"],["2014","","2000","1990","2005"],["xyz","","Abc","jkl","mno"]]  
};

var secondJson = {"criterias":"Location"};

firstJson.criterias = $.extend({},firstJson.criterias,secondJson.criterias);

The simplest way to include one file in another is to use cpp (C preprocessor).

将一个文件包含在另一个文件中的最简单方法是使用 cpp（C 预处理器）。

For example, if I have test.json as

例如，如果我有 test.json 作为

{"name":"NAME",
#include "another.json"
}

and another.json as

和 another.json 作为

"inner":"value"

you should be able to obtain

你应该能够获得

$ cpp -P test.json
{"name":"NAME",
"inner":"value"
}

Of course, you will need to make sure that resulting syntax is correct by properly formatting both pieces.

当然，您需要通过正确格式化这两部分来确保生成的语法是正确的。

Here is the example of how you write nested JSON

这是你如何写作的例子 nested JSON

{"menu": {
   "id": "file",
   "value": "File",
   "popup": {
       "menuitem": [
           {"value": "New", "onclick": "CreateNewDoc()"},
           {"value": "Open", "onclick": "OpenDoc()"},
           {"value": "Close", "onclick": "CloseDoc()"}
        ]
   }
 }}
