vue项目增加倒计时功能

需要使用vue-countdown来实现

1. 下载&引入

2. 使用

HTML部分：

<div id="app">
  <countdown :time="time" :interval="100" tag="p">
    <template slot-scope="props">New Year Countdown：{{ props.days }} days, {{ props.hours }} hours, {{ props.minutes }} minutes, {{ props.seconds }}.{{ Math.floor(props.milliseconds / 100) }} seconds.</template>
  </countdown>

  <countdown ="time" tag="p">
    <template slot-scope="props">Christmas Time Remaining: {{ props.totalDays }} days / {{ props.totalHours }} hours / {{ props.totalMinutes }} minutes / {{ props.totalSeconds }} seconds / {{ props.totalMilliseconds }} milliseconds.</template>
  </countdown>

  <button type="button" class="btn btn-secondary" :disabled="counting" @click="startCountdown">
    <countdown v-if="counting" :time="60000" @end="handleCountdownEnd">
      <template slot-scope="props">Fetch again {{ props.totalSeconds }} seconds later</template>
    </countdown>
    <span v-else>Fetch Verification Code</span>
  </button>
</div>

js部分：

window.onload = function () {
    Vue.component(VueCountdown.name, VueCountdown);

    new Vue({
      el: '#app',
      data: function () {
        var now = new Date();
        var newYear = new Date(now.getFullYear() + 1, 0, 1);

        return {
          counting: false,
          time: newYear - now,
        };
      },
      methods: {
        startCountdown: function () {
          this.counting = true;
        },
        handleCountdownEnd: function () {
          this.counting = false;
        },
      }
    });
  };

总结： 是需要将开始的时间戳绑定给time即可
