TypeScript 此表达式不可调用。 类型 "Number" 没有调用签名。ts(2349) Snake.ts(64, 22): 是否缺少分号?

TS 报错：

类型 "String" 没有调用签名。ts(2349)

Snake.ts(67, 63): 是否缺少分号?

let XX = (this.bodies[i-1] as HTMLElement).offsetLeft
let YY = (this.bodies[i-1] as HTMLElement).offsetTop
            
// 将值设置为当前身体上
(this.bodies[i] as HTMLElement).style.left = XX + 'px'
(this.bodies[i] as HTMLElement).style.top = YY + 'px'

 

解决方案：

在每一个后面加上 ;

            let XX = (this.bodies[i-1] as HTMLElement).offsetLeft;
            let YY = (this.bodies[i-1] as HTMLElement).offsetTop;
            
            // 将值设置为当前身体上
            (this.bodies[i] as HTMLElement).style.left = XX + 'px';
            (this.bodies[i] as HTMLElement).style.top = YY + 'px';
