利用vue做一个倒计时抢购的组件

需求就是如上图,我也是看见朋友在做这个需求,所以想着用vue也实现一下 

其实这里主要就是用到了定时器

用vue实现的话还是比较简单的

以下是我实现的结果,倒计时结束,点击抢购按钮,弹出开始抢购的alert

 实现代码如下

<template>
  <div>
    <div class="container">
      <div class="left">
        <span class="title1">杭州市通用5元券</span>
        <span>杭味面馆</span>
      </div>
      <button class="right" :disabled="isTrue" @click="btnCick()">
        {{ time }}
      </button>
    </div>
  </div>
</template>
 
<script>
export default {
  data() {
    return {
      time: 10, //倒计时
      timer: null, //定时器
      isTrue: true, //控制按钮是否可用
    }
  },
  methods: {
    daoJiShi() {
      this.timer = setTimeout(() => {
        this.time = this.time - 1
        if (this.time == 0) {
          this.time = '开始抢购'
        }
      }, 1000)
    },
    btnCick() {
      alert('可以开始抢购啦')
    },
  },
  mounted() {
    setInterval(() => {
      if (this.time == '开始抢购') {
        this.isTrue = false
        clearInterval(this.timer)
      }
      this.daoJiShi()
    }, 1000)
  },
}
</script>
 
<style lang="scss" scoped>
.container {
  height: 136px;
  width: 430px;
  border-radius: 12px;
  background-color: #fff0f1;
  display: flex;
  justify-content: space-around;
  align-items: center;
  .left {
    display: flex;
    flex-direction: column;
    align-items: flex-start;
    .title1 {
      padding-bottom: 5px;
      font-size: 24px;
      font-weight: bold;
    }
  }
  .right {
    width: 108px;
    height: 45px;
    border-radius: 8px;
    font-size: 20px;
    background-color: #f00;
    color: white;
    border: none;
  }
}
</style>
