How to use js to get the local time as a local pointer

Make a mechanical clock, clock background, and create an animation effect of three-hand deflection

1. Get the local time

Get the three-hand Object (no details about the style)

var h = document.getElementById("h");
var m = document.getElementById("m");
var s = document.getElementById("s");

Get local time

function setTime(){
var date = new Date();

1)

//思路：设置秒针旋转角度;60 = 360deg; 1 = 6deg;
var seceonds = date.getSeconds();//获取当前秒数
s.style.transform=" rotate("+6*senconds+"deg)";
//(style中的样式transform =rotate(x deg))旋转多少度；
// 60分钟 = 360deg 1分钟=6deg;
var minutes = date.getMinutes();
m.style.transform = "rotate(" + 6 * minutes + "deg)";
//设置时针
//12小时 = 360deg 1小时=30deg
var hours = date.getHours();
h.style.transform = "rotate(" + 30 * hours + "deg)";
}
setTime();函数调用执行
setInterval(setTime,1000);
