This function parses a JSON formatted string into variables. You can use toJSON to encode variables into a JSON string that can be read by this function.

Syntax

var fromJSON ( string json )

Required Arguments

json: A JSON formatted string

Returns

Returns variables read from the JSON string.

Note: Indices of a JSON object such as "1": "cat" are being returned as string, not as integer.

Example

This makes data equal: { ["1"] = "cat", ["2"] = "mouse", ["3"] = 5, ["4"] = null, ["cat"] = 5, ["mouse"] =1 }

local data = fromJSON ( '[ { "1": "cat", "2": "mouse", "3": 5, "4": null, "cat":5, "mouse":1 } ]' )

Example 2

local name, weapon, ammo = fromJSON("[\"Desert Eagle\", 24, 147]")
