vue实现左侧滑动删除

IM截图20190605174729.jpg

直接封装成组件，多处可以调用，话不多说，上代码

<template>
  <div class="container">
    <ul>
      <li class="list-item " v-for="(item,index) in list " data-type="0" :key="index">
        <div class="list-box" @touchstart.capture="touchStart" @touchend.capture="touchEnd" @click="skip">
          <img class="list-img" :src="item.imgUrl" alt="">
          <div class="list-content">
            <p class="title">{{item.title}}</p>
            <p class="tips">{{item.tips}}</p>
            <p class="time">{{item.time}}</p>
          </div>
        </div>
        <div class="delete" @click="deleteItem" :data-index="index">删除</div>
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  props: {
    list: {
      type: Array,
      required: true
    }
  },
  data () {
    return {
      startX: 0,
      endX: 0
    }
  },
  methods: {
    // 跳转
    skip () {
      if (this.checkSlide()) {
        this.restSlide()
      } else {
        this.$router.push({
          path: '/detail'
        })
      }
    },
    // 滑动开始
    touchStart (e) {
      // 记录初始位置
      this.startX = e.touches[0].clientX
    },
    // 滑动结束
    touchEnd (e) {
      // 当前滑动的父级元素
      let parentElement = e.currentTarget.parentElement
      // 记录结束位置
      this.endX = e.changedTouches[0].clientX
      // 左滑
      if (parentElement.dataset.type == 0 && this.startX - this.endX > 30) {
        this.restSlide()
        parentElement.dataset.type = 1
      }
      // 右滑
      if (parentElement.dataset.type == 1 && this.startX - this.endX < -30) {
        this.restSlide()
        parentElement.dataset.type = 0
      }
      this.startX = 0
      this.endX = 0
    },
    // 判断当前是否有滑块处于滑动状态
    checkSlide () {
      let listItems = document.querySelectorAll('.list-item')
      for (let i = 0; i < listItems.length; i++) {
        if (listItems[i].dataset.type == 1) {
          return true
        }
      }
      return false
    },
    // 复位滑动状态
    restSlide () {
      let listItems = document.querySelectorAll('.list-item')
      // 复位
      for (let i = 0; i < listItems.length; i++) {
        listItems[i].dataset.type = 0
      }
    },
    // 删除
    deleteItem (e) {
      // 当前索引
      let index = e.currentTarget.dataset.index
      // 复位
      this.restSlide()
      // 删除
      this.list.splice(index, 1)
    }
