JS代码段：VUE下的时间，星期和年月日

不为别的，只为以后复制粘贴方便

data() {
    return {
      date: "",
      time: "",
      week: ""
    };
  },

//vm.timeOffset是与服务器时间的偏移量，不用的话自行删掉

methods: {
    //获取当前时间
    getNowTime: function() {
      let vm = this;
      var nowLocalTime = Date.parse(new Date());
      var nowTime = new Date(nowLocalTime + vm.timeOffset);
      var year = nowTime.getFullYear();
      var mounth =
        nowTime.getMonth() + 1 < 10
          ? "0" + (nowTime.getMonth() + 1)
          : nowTime.getMonth() + 1;
      var date =
        nowTime.getDate() < 10 ? "0" + nowTime.getDate() : nowTime.getDate();
      vm.date = year + "-" + mounth + "-" + date;
      var hour =
        nowTime.getHours() < 10 ? "0" + nowTime.getHours() : nowTime.getHours();
      var minute =
        nowTime.getMinutes() < 10
          ? "0" + nowTime.getMinutes()
          : nowTime.getMinutes();
      vm.time = hour + ":" + minute;
      if (nowTime.getDay() == 0) {
        vm.week = "星期天";
