What is the process for updating a variable within a JSON file?

I am looking to update the state value in my json data. I am creating a game using HTML and JavaScript, and within my JSON file, I have players with attributes such as name, password, and state.

The task at hand is to specifically target the state property and change it from 1 to 3 if necessary.

How can I write code that will only modify the player.state from 1 to 3?

Below is an example of the JSON file:

[
    {"pseudo":"player1","password":"player","state":"1"},
    {"pseudo":"player2","password":"player","state":"0"}
]
javascriptjson

Answer №1

Here is a simple way to achieve this:

function updatePlayerState(playersArray, playerToFind, newState){
     playersArray.find(function(player) {return player.pseudo == playerToFind}).state = newState;
}

var playersList = [
    {"pseudo":"player1","password":"player","state":"1"},
    {"pseudo":"player2","password":"player","state":"0"}
]

updatePlayerState(playersList,"player2",3);
