js解析

先通过document.querySelector('.xxx') 获取元素secondHand，minHand 和hourHand ，通过new Date() 获取当前时间，并命名now 为其值，再分别通过now.getSeconds()，now.getMinutes()，now.getHours() 来获取秒，分，时，并分别命名为seconds，mins，hours ，再分别通过seconds/60*360+90 获取秒针的度数secondsDegrees ，mins/60*360+90 获取分针的度数 minsDegrees 和hours/12360+90+(mins/60)/12360 获取时针的度数hoursDegrees ，最后通过xxx.style.transform=rotate(${ xxx}deg) 将度数转化为带deg单位的数值。
