Lua Requires Chilkat v9.5.0.82+

JSON AddArrayCopyAt Example

Demonstrates the AddArrayCopyAt function. Lua

local chilkat = require("chilkat")

local json = chilkat.JsonObject.new()
json:load("{ \"name\": \"John\", \"marbles\": 100 }")

local jarr = chilkat.JsonArray.new()
jarr:load("[ 1, 2, 3, \"apple\", \"orange\", [ 10, 20, 30 ], { \"name\": \"Luther\"} ]")

-- Copy the contents of jar to a new array member named "stuff".
-- Insert the array at the 2nd position
json:add_array_copy_at(1, "stuff", jarr)

print(json:emit())
-- Expected output is:  {"name":"John","stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Luther"}],"marbles":100}

-- Note: The contents of the array were copied.
-- If we modify the contents of jarr, it does not modify the array contained within "json" because it is a separate copy.
-- For example:
jarr:add_int_at(-1, 2020)
print(jarr:emit())
-- Expected output: [1,2,3,"apple","orange",[10,20,30],{"name":"Luther"},2020]

print(json:emit())
-- Remains unchanged: {"name":"John","stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Luther"}],"marbles":100}
