工作台，是每个后台系统必备的，也是管理系统的首页。这次我们来实现一个工作台，并适配他的响应性

实现效果

代码实现

• 封装echarts组件
• 引入Tailwind CSS，简化我们书写css样式

<script setup>
import { ref, onMounted } from "vue";
import {
  Pointer,
  Tickets,
  DataAnalysis,
  DataLine,
  Monitor,
  Van,
  Guide,
  Calendar
} from "@element-plus/icons-vue";
import BarPie from "@/components/echarts/bar.vue";
import LinePie from "@/components/echarts/line.vue";
import chartPieRef from "@/components/echarts/pie.vue";
const handleClick = (tab, event) => {
  console.log(tab, event);
};
const activeName = ref("first");
//柱状图的数据
const chartData = [
  {
    name: "衬衫",
    value: "5"
  },
  {
    name: "羊毛衫",
    value: "10"
  },
  {
    name: "雪纺衫",
    value: "15"
  },
  {
    name: "裤子",
    value: "20"
  },
  {
    name: "高跟鞋",
    value: "25"
  }
];
const option = {
  title: {
    text: "流量趋势"
  },
  tooltip: {},
  yAxis: {}
};
const option1 = {
  title: {
    text: "访问量"
  },
  tooltip: {},
  yAxis: {}
};
const pieData = [
  { value: 1048, name: "Search Engine" },
  { value: 735, name: "Direct" },
  { value: 580, name: "Email" },
  { value: 484, name: "Union Ads" },
  { value: 300, name: "Video Ads" }
];
</script>


<style scoped>
</style>

组件的封装

• 以饼图为例

<template>
  <div ref="chartPieRef" :style="{ height:height, width }"></div>
</template>

<script>
import {
  unref,
  nextTick,
  watch,
  computed,
  ref,
  defineComponent,
  reactive,
  watchEffect
} from "vue";
import { useEcharts } from "@/hooks/useEcharts";
export default defineComponent({
  name: "bar",
  props: {
    chartData: {
      type: Array,
      default: () => []
    },
    option: {
      type: Object,
      default: () => ({})
    },
    width: {
      type: String,
      default: "100%"
    },
    height: {
      type: String,
      default: "calc(100vh - 78px)"
    }
  },
  setup(props) {
    //创建dom节点的引用
    const chartPieRef = ref(null);
    const { echarts, setOptions } = useEcharts(chartPieRef);
    const COLORS = [
      "#c23531",
      "#2f4554",
      "#61a0a8",
      "#d48265",
      "#91c7ae",
      "#749f83"
    ];
    //默认的配置
    const option = reactive({
      tooltip: {
        trigger: "item"
      },
      legend: {
        top: "5%",
        left: "center"
      },
      series: [
        {
          name: "pie",
          name: "Access From",
          type: "pie",
          radius: ["40%", "70%"],
          avoidLabelOverlap: false,
          itemStyle: {
            borderRadius: 10,
            borderColor: "#fff",
            borderWidth: 2
          },
          label: {
            show: false,
            position: "center"
          },
          emphasis: {
            label: {
              show: true,
              fontSize: 40,
              fontWeight: "bold"
            }
          },
          labelLine: {
            show: false
          },
          data: []
        }
      ]
    });
    //监听父组件传递的属性变化，时时响应变化
    watchEffect(() => {
      props.chartData && initCharts();
    });

    function initCharts() {
      if (props.option) {
        Object.assign(option, props.option);
      }

      console.log(option, "option");
      option.series[0].data = props.chartData;
      setOptions(option);
    }
    return {
      chartPieRef
    };
  }
});
</script>

<style></style>

这样我们就实现了一个大概的dashboard页面，细节需要自己去完善美化了。
