echarts组件引入

<template>
  <div>
    <div id="main" style="width: 600px;height:400px;"></div>
  </div>
</template>

<script setup>
import { onMounted, ref } from 'vue';
import * as echarts from 'echarts';
import api from '@/components/utils/api'

const boxlist = ref([])
const mc = ref([])
const jg = ref([])


const chafen = () => {
  boxlist.value.forEach(item => {
    mc.value.push(String(item.name))
    jg.value.push(Number(item.price))
    console.log(mc.value, jg.value);
    // console.log(item);
  });
}

const zhuxing = () => {
  // 基于准备好的dom，初始化echarts实例
  var myChart = echarts.init(document.getElementById('main'));

  // 指定图表的配置项和数据
  var option = {
    title: {
      text: 'ECharts与后台交互示例'
    },
    tooltip: {},
    legend: {
      data: ['销量']
    },
    xAxis: {
      data: mc.value
    },
    yAxis: {},
    series: [
      {
        name: '销量',
        type: 'bar',
        data: jg.value
      }
    ]
  };
  // 使用刚指定的配置项和数据显示图表。
  myChart.setOption(option);
}


onMounted(async () => {
  const { data: { data } } = await api.get('zx')
  boxlist.value = data
  chafen()
  zhuxing()
})
</script>

<style lang="scss" scoped></style>

前端代码

<template>
    <div class="body">
        <div class="box">
            <count-up v-for="(val, index) in endVal" :key="index" :end-val="val" :duration="duration"

<script setup lang="ts">

const count=ref(null)

const data = reactive({
    startVal: 0, // 开始值
    endVal:  computed(()=>([count.value, 5000, 10000])), // 结束值 -- 可以写成动态的
    duration: 5, // 跳动时长 - 单位：秒

    countUp: undefined as ICountUp | undefined, // 跳动的对象
    // countUps: [] as Array<ICountUp> | [], // 跳动的对象数组

</script>

<style lang="less" scoped>
.body {
    .box {
        display: flex;
        justify-content: flex-start;

        // font-weight: bold;
        .count {
            font-size: 20px;
            font-weight: bold;
            margin: 0 30px;
        }
    }
}
</style>
  

后端代码

后端配置参考地址

var express = require("express");
var router = express.Router();
const mongoose = require("mongoose");

const Zhuxing = mongoose.model("zhuxing",{name:String,price:Number},'zhuxing')
// Zhuxing.create({
//   name:'周日',
//   price:6000
// })

router.get("/zx", async function (req, res, next) {
  const data = await Zhuxing.find();
  // console.log(data);
  res.send({ code: "200", message: "zx show ok", data });
});

module.exports = router;
