Tutorial: Adding an Array Value Type to a JavaScriptObjectNotation Object

This tutorial tells you how to add an array value to a JavaScriptObjectNotation (JSON) object

Adding an Array Value Type to a JavaScriptObjectNotation Object

In this tutorial we will create an array using JavaScriptObjectNotation which we will call “array.” We will use "array" as a corresponding value for the key name “detail” in a JavaScriptObjectNotation object called “json.” We will then output the final result. We begin by adding the necessary JavaScriptObjectNotation library and creating our JavaScriptObjectNotation object "array" to be used as a value in our JavaScriptObjectNotation object "json".

use Libraries.Data.Formats.JavaScriptObjectNotation

class Main
   action Main
        //creates a JavaScriptObjectNotation object "array"
       JavaScriptObjectNotation array
        //sets the JavaScriptObjectNotation object "array" to type Array.
       array:SetArray()
        //Adds the values of "project1" and "project2" to "array"
       array:Add("arrayValue1")
       array:Add("arrayValue2")

Finally, we need to “Add” the JavaScriptObjectNotation object value “array” to the JavaScriptObjectNotation object “json”.

       JavaScriptObjectNotation json
       json:Add("data1", 10)
       json:Add("data2", 11)
       json:Add("myArray", array)

Here is the complete code section which will add an array value to a JavaScriptObjectNotation object and output the { name : value } pairs in JavaScript Object Notation format.

use Libraries.Data.Formats.JavaScriptObjectNotation

class Main
   action Main
       JavaScriptObjectNotation array
       array:SetArray()
       array:Add("arrayValue1")
       array:Add("arrayValue2")
       JavaScriptObjectNotation json
       json:Add("data1", 10)
       json:Add("data2", 11)
       json:Add("myArray", array)
       json:SetPrettyPrint(true)
       output json:ToText()
   end
end

The final result should look like this, with the “array” values separated by commas and enclosed within square brackets:

{
       "data1": 10,
       "data2": 11,
       "myArray": ["arrayValue1", "arrayValue2"]
}
