数组内对象中的整数不减少

问题描述

我制作了这段代码，当运行时向 mzone 添加一个值，最大为 3，五秒后应该减少添加的值，但最后一部分不起作用。我还在学习，所以我不知道可能有什么问题。

    clubsList[playerCountry].mzone = (clubsList[playerCountry].mzone + 1) || 1; //This works perfectly. It adds 1 to the mzone everytime it's run.
    console.log(clubsList[playerCountry].mzone)
    setTimeout(function(){ (clubsList[playerCountry].mzone - 1 ) },5000); //This isn't working
    setTimeout(function(){ (console.log(clubsList[playerCountry].mzone)) },6000);

完成的代码：

clubsList = []

onNet('verifyMeetingzone',(playerCountry) => {
    if (!clubsList[playerCountry]) {
        clubsList[playerCountry] = {}
        clubsList[playerCountry].mzone = 0
    }
    // HERE
    if (clubsList[playerCountry].mzone <= 2) {
        console.log("Mzone Criado")  
        clubsList[playerCountry].mzone = (clubsList[playerCountry].mzone + 1) || 1; 
        console.log(clubsList[playerCountry].mzone)
        setTimeout(function(){ (clubsList[playerCountry].mzone - 1 ) },5000);
        setTimeout(function(){ (console.log(clubsList[playerCountry].mzone)) },6000);
    }
    else {
        console.log("Ja existe")  
    }
})

解决方法

我应该改变这个：

    setTimeout(function(){ (clubsList[playerCountry].mzone - 1 ) },5000);

为此：

    setTimeout(function(){ (clubsList[playerCountry].mzone = clubsList[playerCountry].mzone - 1) },5000);

,

我认为您没有将更改后的值重新分配给对象，这就是对象没有接收减量的原因：

 setTimeout(function(){ clubsList[playerCountry].mzone = clubsList[playerCountry].mzone - 1  },5000);

试试这个，应该可以解决问题。
