vue项目-圆柱状水波效果实现

1、先在data中定义有关参数和引入数据请求接口

1、字data中定义需要用到的参数

specialList: [
    { value: 0, height: 0, markKey: '' },
    { value: 0, height: 0, markKey: '' },
    { value: 0, height: 0, markKey: '' },
    { value: 0, height: 0, markKey: '' }
]

2、引入数据请求接口

import { getMarks } from '@/api/businessOpetation'

2、再进行真实数据的获取

created() {
    getMarks(22).then((res) => {
      console.log(res)
      if (res.code === 200) {
        res.data.result.forEach((item, index) => {
          const value = JSON.parse(item.markValue).value || 0
          const height = 126 - 126 * (1 - value * 0.01)
          const obj = {}
          obj.markKey = item.markKey
          obj.value = value
          obj.height = height
          this.$set(this.specialList, index, obj)
        })
      }
    })
  },

3、核心代码（主要是html和CSS代码）

HTML代码：

<div class="box1">
    <div
      class="box1-item"
      v-for="(item, index) in specialList"
      :key="index">
      <div class="img-box">
        <div class="lui-column-bg">
          <img
            :src="require('@/assets/images/business/cylinder_bg.png')"
            alt=""/>
          <span class="item-value" :style="{ opacity: item.value }">{{
            item.value
          }}</span>
          <div
            class="lui-inner"
            :class="['lui-inner' + index]"
            :style="{ height: (item.height || 0) + 'px' }">
            <div
              v-show="item.height > 0 && item.height < 142"
              class="gif-box"
              :class="[`gif-box${index}`]"
            ></div>
          </div>
        </div>
      </div>
      <span class="box1-adderss" :class="[`box1-adderss${index}`]">{{
        item.markKey
      }}</span>
    </div>
</div>

4、需要的图片素材

需要用到9张png图片和4张gif图

5、最终效果

说明：图片截的是静态图片，现实柱状图是有水波的
