如何更改JSON文件中的变量？

Question

我需要更改json文件中的state， 我必须在我的json中使用HTML和javascript进行游戏，我的玩家拥有名称，密码和状态等属性。

我的请求只需要查看state个数字，并在必要时进行更改。

如何编写仅更改player.state的代码，从1到3？

这是JSON文件

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

您可以执行以下操作：

＆＃13;

＆＃13;

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

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

changeState(players,"player2",3);

＆＃13;
