1-需求页面

2-头部需求分析

上面头部有四个card，card分为上中下三部分，其中上都是文字描述和一个小图标；中间部分有文字，折线图，柱状图和类似进度条之类的，中间部分不一样，使用插槽slot进行；下面结构有文字和上下箭头，我们也使用插槽进行。我们将单个card封装为一个组件。

结构代码：

js和样式代码如下：

<script>
export default {
  name: '',
  props:['title','count']
}
</script>

<style scoped>
 .card-header{
    display: flex;
    justify-content: space-between;
    color:#d9d9d9;
 }
.card-content{
  font-size: 30px;
  padding: 10px 0px;
}
.card-charts{
  height: 50px;
}
.card-footer{
  border-top: 1px solid #eee;
  padding-top: 10px;
}
</style>

父组件中使用

card里面使用detail子组件

第二个card里面需要插入折线图

中间部分折线图，柱状图和进度条使用子组件的形式。

折线图组件：src\views\dashboard\Card\lineChart\index.vue

3-中间部分需求分析

中间部分分为左侧和右侧两部分，默认展示销售额数据，切换tab的时候要展示访问量的数据；这部分数据我们通过mock来获取，动态展示。

3.1-mock数据

之前的数据我们都是通过请求后端服务器来获取的，现在首页这块数据我们需要通过mock来获取。
1-准备需要mock的数据；新建文件：mock\data.json；
2-由于首页组件嵌套比较多，我们父子传输数据层次多，我们采用vuex来从仓库获取数据。src\store\modules\home.js新建仓库；注册仓库；

我们发送请求是发送到mock里面

首页挂载完成的时候发送action

3.2-动态渲染数据

销售组件：src\views\dashboard\Sale\index.vue
组件中我们分左右两侧内容，柱状图和排名宽度大小分别占18和6，因为一共是24。默认展示销售额。通过计算和监听来动态渲染数据是销售额还是访问量。

4-底部需求分析

由于底部左侧的折线图，我们上面已经实现了类似的功能，左侧我们忽略；主要看右侧的饼状图。首先需要展示饼状图，然后鼠标移动上去，显示对应的数据。并且圆圈内部显示对应的文本标题。子组件：src\views\dashboard\Observe\Category\index.vue；

<template>
  <el-card>
    <div slot="header" class="header">
      <div class="category-header">
        <span>销售额类别占比</span>
        <el-radio-group v-model="value">
          <el-radio-button label="全部渠道"></el-radio-button>
          <el-radio-button label="线上"></el-radio-button>
          <el-radio-button label="门店"></el-radio-button>
        </el-radio-group>
      </div>
    </div>
    <div>
      <div class="charts" ref="charts"></div>
    </div>
  </el-card>
</template>

<script>
import echarts from "echarts";
export default {
  name: "",
  data() {
    return {
      value: "全部渠道",
    };
  },
  mounted() {
    //饼图
    let mychart = echarts.init(this.$refs.charts);
    mychart.setOption({
      title: {
        text: "视频",
        subtext: 1048,
        left: "center",
        top: "center",
      },
      tooltip: {
        trigger: "item",
      },
      series: [
        {
          name: "Access From",
          type: "pie",
          radius: ["40%", "70%"],
          avoidLabelOverlap: false,
          itemStyle: {
            borderRadius: 10,
            borderColor: "#fff",
            borderWidth: 2,
          },
          label: {
            show: true,
            position: "outsize",
          },
          labelLine: {
            show: true,
          },
          data: [
            { value: 1048, name: "视频" },
            { value: 735, name: "Direct" },
            { value: 580, name: "Email" },
            { value: 484, name: "Union Ads" },
            { value: 300, name: "Video Ads" },
          ],
        },
      ],
    });
    //绑定事件

    mychart.on("mouseover",(params)=>{
        //获取鼠标移上去那条数据
        const {name,value} = params.data;
        //重新设置标题
        mychart.setOption({
          title:{
            text:name,
            subtext:'value'
          }
        })
    });
  },
};
