vue柱状进度条图像的完美实现方案

前言

本文是对bar进度条实现的2种方案进行分享，第一种是很简单，纯css的实现，第二种是echart的实现。

css的实现

css实现很简单。代码如下：

<template>
 <div class="haoroomflex">
  <div v-for="(item,index) in bardata" :key="index" class="onebar">
   <div class="bar">
    <span class="progress" :style="{'height':`${item.value*100}%`}" />
   </div>
   <div class="sfont">{{ item.date }}</div>
  </div>

 </div>
</template>
<script>

export default {
 props: {
  bardata: {
   type: array,
   default() {
    return [
     { date: '', value: 0 },
     { date: '', value: 0 },
     { date: '', value: 0 }
    ]
   }
  }
 }

}
</script>
<style rel="stylesheet/scss" lang="scss" scoped>
.haoroomflex{display: flex;margin:0 15px;}
.onebar{
 flex:1;
 text-align: center;
 min-width: 30px;
 max-width: 100px;
 display: inline-block;
 .sfont{
  color:#999;
  font-size:14px;
 }
 .bar{
  height: 160px;
  width:24px;
  margin:5px auto;
  -webkit-border-radius: 24px;
  border-radius: 24px;
  overflow: hidden;
  position: relative;
  background: #e5e5e5;
  span.progress {
   position: absolute;
   bottom:0;
   height: 0;
   width: 100%;
   display: block;
   -webkit-border-radius: 24px;
   border-radius: 24px;
   -webkit-transition: height 2s ease-out;
   -o-transition: height 2s ease-out;
   transition: height 2s ease-out;
   background: #3990ff

  }
 }
}
</style>

效果如下

 

echart实现

<template>
 <div class="linechartwrap">
  <v-chart class="barchart" :options="options" autoresize />
 </div>
</template>

<script>
import echarts from 'vue-echarts'
import 'echarts/lib/chart/bar'
import 'echarts/lib/component/tooltip'
import 'echarts/lib/component/title'
import 'echarts/lib/component/toolbox'

export default {
 components: {
  'v-chart': echarts
 },
 props: {
  bardata: {
   type: object,
   default() {
    return {
     data: [11, 33, 77],
     title: ['07-01', '07-02', '07-03']
    }
   }
  }
 },
 computed: {
  options() {
   return {
    grid: {
     show: 'true',
     borderwidth: '0',
     height: '72%',
     width: '90%',
     x: '12%',
     y: '20%'
    },
    tooltip: {
     trigger: 'axis',
     axispointer: {
      type: 'none'
     },
     formatter: '{b0}: {c0}%'
    /* formatter: function(params) {
      var result = '';
      params.foreach(function (item) {
        result += item.marker + " " + item.seriesname + " : " + item.value +"</br>";
      });
      return result;
    }*/
    },
    backgroundcolor: '#fff', // 背景色
    yaxis: {
     show: false, // 是否显示x轴
     type: 'value'
    },
    xaxis: {
     type: 'category',
     axislabel: {
      show: true,
      textstyle: {
       color: '#666' // y轴字体颜色
      }
     },
     splitline: { show: false }, // 横向的线
     axistick: { show: false }, // y轴的端点
     axisline: { show: false }, // y轴的线
     data: this.bardata.title
    },
    series: [
     {
      type: 'bar',
      itemstyle: {
       normal: {
        barborderradius: 25,
        color: '#3990ff'
       }
      },
      barwidth: 25,
      data: this.bardata.data
     },
     {
      name: '外框',
      type: 'bar',
      itemstyle: {
       normal: {
        barborderradius: 25,
        color: '#e5e5e5' // rgba设置透明度0.14
       }
      },
      bargap: '-100%',
      z: 0,
      barwidth: 25,
      data: [100, 100, 100]
     }
    ]
   }
  }
 }

}
</script>
