JSON Iterate Members

See more JSON Examples

Demonstrates how to loop over the immediate members of a JSON object. Lua

local chilkat = require("chilkat")

local json = chilkat.JsonObject.new()

local jsonStr = "{ \"id\": 1, \"name\": \"A green door\", \"tags\": [\"home\", \"green\"], \"price\": 125 }"

local success = json:load(jsonStr)
if not success then
    print(json.last_error_text)
    return
end

local numMembers = json.size
for i = 0, numMembers - 1 do
    local name = json:name_at(i)
    local value = json:string_at(i)

    print(name .. ": " .. value)

    local iValue = json:int_at(i)
    print(name .. " as integer: " .. iValue)
end

-- Note: The StringAt method returns the value as a string regardless of the type.
-- If the value is a JSON array (such as for ["home", "green"]), then the JSON encoding
-- of the entire array is returned.

-- The IntAt method returns the value as an integer.  If the value does not convert to
-- an integer, then 0 is returned.
