// 设置实时时间
function setTime() {
// 获取当时时间
const now = new Date()
// 获取当时的秒数
const seconds = now.getSeconds();
// 设置秒针的实时视点
// 加90是将秒针初始方位就设置在0秒
const secondsDegrees = seconds * 6 90
secondHand.style.transform = `rotate(${secondsDegrees}deg)`
// 设置分针的实时视点
// 加90也是为了让分钟初始方位在0分处

const minsDegrees = mins * 6 90
