json.path.put() Function
• Introduced in version 1.5.5
Create or update the key with the given value at the given path of a nested JSON Object. json.path.put() is only used creating/updating name/value pairs in JSON Objects. See json.path.set() for creating/updated values in arrays. Additional information on how to specify the path is available here.
Usage
json.path.put(json, path, key, value)Parameters
json- The json element in which the JSON Object is nested.path- The path to the JSON Object.key- The key of the JSON Object.value- The value to associated with the key.
Examples
Suppose we have the following nested json:
[h:troll = json.set("{}", "name", "Troll", "HP", 75, "Attacks", json.append("Claw", "Bite"))]
[h:orc = json.set("{}", "name", "Orc", "HP", 13, "Attacks", json.append("Sword", "Punch"))]
[h:monsters = json.set("{}", "Troll", troll, "Orc", orc)]Which looks like this:
{
"Troll": {
"name": "Troll",
"HP": 75,
"Attacks": [
"Claw",
"Bite"
]
},
"Orc": {
"name": "Orc",
"HP": 13,
"Attacks": [
"Sword",
"Punch"
]
}
}
To add a new "AC" value to the troll, we could write
[h: monsters = json.path.put(monsters, "Troll", "AC", 12)]
<pre>[r: json.indent(json.get(monsters,"Troll"),2)]</pre>And see this:
{
"name": "Troll",
"HP": 75,
"Attacks": [
"Claw",
"Bite"
]
"AC": 12
}
