vue 自己封装 进度条 组件

需要实现的效果是这样的：

直接上代码：

父组件关键代码：

html：

<div class="left-bottom-bar">
        <progress-bar />
      </div>

js：

import progressBar from '@/components/ProgressBar'
export default {
  components:{
    progressBar
  },
}

css：

.left-bottom-bar{
  background: #fff;
  height: 50px;
  margin-top:10px;
  border-radius: 3px;
  display: flex;
  align-items: center;
  padding:0 40px 0 40px;
}

子组件(进度条组件)完整代码：

<style lang="less" scoped>
.progress-bar{
  width:100%;
  position: relative;
  .p-line{
    position: absolute;
    z-index: 1;
    width:100%;
    height: 10px;
    border-radius: 4px;
    background-color: #EEEEEE;
  }
  .p-done{
    position: absolute;
    z-index: 2;
    // width:80%;
    height: 10px;
    border-radius: 4px;
    background: linear-gradient(45deg, #40A9FF 25%, #1890FF 0, #1890FF 50%, #40A9FF 0, #40A9FF 75%, #1890FF 0);
    background-size: 30px 30px;
  }
  .top-num{
    margin-left:-30px;
    margin-right:-80px;
    text-align: left;
    .text-bar{
      font-size: 13px;
    }
    .text-icon{
      color:#008CDB;
      padding-left:20px;
      margin-top:-5px;
      i{
        font-size:18px;
      }
    }
  }
  .bottom-num{
    width:100%;
    padding-top:15px;
  }
}
</style>
<template>
  <div class="progress-bar">
     <div class="top-num" :style="{paddingLeft:doneWidth}">
          <div class="text-bar">药费：￥{
   
   {drugCost}}</div>
          <div class="text-icon"><i class="el-icon-caret-bottom"></i> </div>
     </div>
     <div class="p-line"></div>
     <div class="p-done" :style="{width:doneWidth}"></div>
     <div class="bottom-num">
       <div style="float:left">0</div>
       <div style="float:right">{
   
   {totalCost}}</div>
     </div>
  </div>
</template>
<script>
export default {
  data(){
    return{
      totalCost:271,
      drugCost:0,
    }
  },
  computed:{
    ratio(){
      const r = this.drugCost/this.totalCost
      return r
    },
    doneWidth(){
      return this.drugCost/this.totalCost*100 + '%'
    }
  },
  created(){},
  mounted(){
    console.log('doneStyle:',this.doneWidth)
  },
  methods:{

  }
}
</script>

完成。
