Question

我是JavaScript的新手，我编写了调用虚拟用户的代码：

function User(){
    this.name = ""
    this.life = 100
    this.givingLifeToAplayer = function(PlayerName){
        PlayerName.life += 1
        console.log(this.name + " gave 1 life to " + PlayerName.name)
    }

}
var Yani = new User()
var jenny = new User()
var Robert = new User()
Yani.name = "Yani"
jenny.name = "Jenny"
Robert.name = "Robert";
Yani.givingLifeToAplayer(jenny)
console.log("Yani has " + Yani.life + " Jenny has " + jenny.life)
jenny.givingLifeToAplayer(Robert)
console.log("Jenny has " + jenny.life + " is the biggest score to " + Robert.life)

每当用户将life传递给其他用户时，如何将life增加1？

Answer 1

你做得对。 PlayerName是User.givingLifeToAplayer中调用参数中对象的引用。编辑引用时，编辑两个对象（参数中的对象和PlayerName）。编辑原始对象时也一样。

所以......你做到了。但是你的代码更具可读性：

function User(name) {
    this.name = name;
    this.life = 100;
    this.addLifeTo = function(player) {
        player.life ++; // increment operator
        console.log(this.name + " gave 1 life to " + player.name);
    }
}
var Yani = new User("Yani"),
    Jenny = new User("Jenny"),
    Robert = new User("Robert");

Yani.addLifeTo(Jenny);
console.log("Yani has " + Yani.life + ". Jenny has " + Jenny.life);
Jenny.addLifeTo(Robert);
console.log("Jenny has " + Jenny.life + "; it's the biggest score to " + Robert.life);

Answer 2

Klaider Klai感谢您的回答每当玩家将分数传给另一位玩家时，我想提高+1分，因为我可以看到Jenny正在将1分传递给Robert，但Robet的分数没有增加1分。非常感谢

Javascript增加1
