vue3 获取格式化当前时间 一秒钟执行一次

const data = reactive({
  time: "",
});
// 定时器间隔一秒执行一次
const intervalId = setInterval(() => {
  data.time = nowDate();
}, 1000);
// 清除定时器
onUnmounted(() => {
  clearInterval(intervalId);
});
const nowDate = () => {
  var time: any = new Date(); //获取到当前时间戳
  var year = time.getFullYear(); // 年
  var month = (time.getMonth() + 1).toString().padStart(2, "0"); // 月
  var date = time.getDate().toString().padStart(2, "0"); // 日
  var hour = time.getHours().toString().padStart(2, "0"); // 时
  var minute = time.getMinutes().toString().padStart(2, "0"); // 分
  var second = time.getSeconds().toString().padStart(2, "0"); // 秒
  console.log(
    year + "-" + month + "-" + date + " " + hour + ":" + minute + ":" + second
  );
  return (
    year + "-" + month + "-" + date + " " + hour + ":" + minute + ":" + second
  );
};
