這篇文章主要為大家詳細(xì)介紹了vue實(shí)現(xiàn)同時(shí)設(shè)置多個(gè)倒計(jì)時(shí)，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了vue實(shí)現(xiàn)同時(shí)設(shè)置多個(gè)倒計(jì)時(shí)的具體代碼，供大家參考，具體內(nèi)容如下

html如下：

<div class="home">
    <tbody>
      <tr v-for="(item, index) in bargainGoods" :key="index">
        <td v-text="item.down + Djs_timeList(item.countDown)"></td>
      </tr>
    </tbody>
</div>

js如下：

export default {
  data() {
    return {
      bargainGoods: [],
      total: 0,
      page: 1,
      serverTime: 0,
      timer: ""
      // hostUrl: this.$hostUrl
    };
  },
  //用于數(shù)據(jù)初始化
  created: function() {
    // 獲取數(shù)據(jù)
    this.goods();
    // 獲取服務(wù)器時(shí)間
    this.findServiceTime();
  },
  methods: {
    goods: function() {
      var _this = this;
      _this.$axios({
        url: "goods/pageGoods",
        data: {
          current: -1,
          activityStatus: "",
          limit: -1,
          status: "SALE"
        },
        success: response => {
          _this.bargainGoods = response.items;
          _this.Djs_time();// 調(diào)用定時(shí)器
          //  以下是我處理的后臺(tái)返回?cái)?shù)據(jù)   開(kāi)始時(shí)間和結(jié)束時(shí)間，頁(yè)面顯示用的
          if (_this.bargainGoods.length != 0) {
            for (var key in _this.bargainGoods) {
              var hour = 0;
              var startime = 0;
              if (_this.bargainGoods[key] != null) {
                _this.bargainGoods[key].countDown = "";
                _this.bargainGoods[key].down = "";

                // 結(jié)束時(shí)間
                hour = _this.bargainGoods[key].overTime;
                startime = _this.bargainGoods[key].activityStartTime;
                hour = hour.replace(/-/g, "/");
                hour = new Date(hour).getTime();
                startime = startime.replace(/-/g, "/");
                startime = new Date(startime).getTime();
                // 如果結(jié)束時(shí)間大于當(dāng)前時(shí)間

                if (hour > _this.serverTime && startime < _this.serverTime) {
                  var hourtime = hour - _this.serverTime;
                  if (hourtime > 0) {
                    _this.bargainGoods[key].down = "結(jié)束倒計(jì)時(shí)：";
                    _this.bargainGoods[key].countDown =
                      _this.bargainGoods[key].overTime;
                  }
                } else if (startime > _this.serverTime) {
                  var starhourtime = startime - _this.serverTime;
                  if (starhourtime > 0) {
                    _this.bargainGoods[key].down = "開(kāi)始倒計(jì)時(shí)：";
                    _this.bargainGoods[key].countDown =
                      _this.bargainGoods[key].activityStartTime;
                  }
                } else {
                  _this.bargainGoods[key].down = "已結(jié)束";
                  _this.bargainGoods[key].countDown = "";
                }
                // console.log(_this.bargainGoods);
              }
            }
            _this.bargainGoods = _this.bargainGoods;
          }
        }
      });
    },
    // 獲取服務(wù)器時(shí)間
    findServiceTime() {
      var _this = this;
      _this.$axios({
        url: "serverTime/getDateTime",
        success: function(res) {
          _this.serverTime = res.item;
        }
      });
    },

    Djs_time: function() {
      this.timer = setInterval(() => {
        this.serverTime = this.serverTime + 1000;
      }, 1000);
    },

    Djs_timeList: function(itemEnd) {
      //  此處 itemEnd 的日期是年月日時(shí)分秒
      var endItem = new Date(itemEnd).getTime(); //獲取列表傳的截止時(shí)間，轉(zhuǎn)成時(shí)間戳
      var nowItem = this.serverTime; //獲取當(dāng)前時(shí)間
      var rightTime = endItem - nowItem; //截止時(shí)間減去當(dāng)前時(shí)間
      if (rightTime > 0) {
        //判斷剩余倒計(jì)時(shí)時(shí)間如果大于0就執(zhí)行倒計(jì)時(shí)否則就結(jié)束
        var dd = Math.floor(rightTime / 1000 / 60 / 60 / 24);
        var hh = Math.floor((rightTime / 1000 / 60 / 60) % 24);
        var mm = Math.floor((rightTime / 1000 / 60) % 60);
        var ss = Math.floor((rightTime / 1000) % 60);
        var showTime = dd + "天" + hh + "小時(shí)" + mm + "分" + ss + "秒";
      } else {
        var showTime = "";
      }
      return showTime;
    },

  },
    //離開(kāi)頁(yè)面后清除定時(shí)器
  destroyed() {
    clearInterval(this.timer);
  }
};

效果如下：
