cocos creator TS类型

Question

public countDownShow(): void {
let baseSecond = EnergyManager.reduiseTime;
baseSecond = baseSecond - 1;
EnergyManager.reduiseTime = baseSecond;
let hour = Math.floor(baseSecond / 3600);
let residue = baseSecond - hour * 3600;
let minute = Math.floor(residue / 60);
residue = residue - minute * 60;
TS 中 下面判断报错 类型'''不能分配''number' 应该如何修改
if (minute < 10) {
minute = "0" + minute;
}
if (residue < 10) {

    residue = "0" + residue;
    }
    this.label.getComponent(cc.Label).string = minute + ":" + residue;
}

Answer 1

代码不完整 ，首先你问什么要把number类型的转换为string类型的 其实你可以另外定义一个string类型的变量，判断之后对string类型的变量进行赋值
