旅游地图 TravelMap

<template>
  <div class="map-view">
    <div id="main"></div>
  </div>
</template>
<!--
  设置一个标签，标签设置宽高，否则不显示
  引入中国地图的数据
  初始化echarts实例，并挂载到dom中
  注册中国地图，必须在geo或map中
  this.$echarts.registerMap("china", geoJson);
  编写配置项，把配置项添加到实例中（简写）
  配置项：
  背景色
  geo：图层（zoom），长宽比例，样式（itemStyle)：地图区域的颜色，阴影，阴影偏移量，特点区域的样式(region)：南海诸岛
  series：相关数据的各项参数，可以分为好几层，层次显示用图层（zoom）划分，
  1. 基础地图相关的数据参数：显示文字，文字颜色，图层，样式（itemStyle)：地图区域的颜色，背景色，边框，高亮效果（鼠标移入时显示样式）

  请求数据（把请求到的值：points, linesData）给2，3的data

  2. 配置散点图的各项参数：类型（type）：散点图（气泡图），使用地理坐标系，配置何时显示特效(绘制完成后显示特效)，标记的大小(默认为10)
    图层：1，data（数据），涟漪特效相关配置：动画周期，缩放比例，波纹的绘制
  3. 配置线性图的各项参数：类型（type）：线性图，图层：2，线特效的配置（effect）：是否显示特效（show），特效动画的时间，显示方式，特效的大小，
    拖尾的效果，取值范围 0-1，值越大效果越明显，线的样式（透明度，颜色，宽，弯曲度），data（数据）

三、Bread 面包屑

<template>
  <div class="bread">
    <el-card>
      <!-- Breadcrumb 面包屑 -->
      <el-breadcrumb separator-class="el-icon-arrow-right">
        <el-breadcrumb-item :to="{ path: '/home' }">首页</el-breadcrumb-item>
        <!-- $route.matched：获取当前页面的路由信息 -->
        <el-breadcrumb-item
          v-for="(item, index) in $route.matched"
          :key="index"
        >
          <router-link :to="{ path: item.redirect }" class="redirects">
            {{ item.name }}
          </router-link>
        </el-breadcrumb-item>
      </el-breadcrumb>
    </el-card>
  </div>
</template>

<script>
export default {};

    font-weight: 400;
  }
}
</style>

四、Footer

<template>
  <div>
    <el-card> Frontend 2022 Csaey </el-card>
  </div>
</template>

<script>
export default {};
</script>

<style></style>

五 、分页器： Pageing

<!-- 这里整个组件是，组件化封装，面试的时候不要忘了-->
<!-- html，css，js 都用上是组件化封装，大部分都是内部，小部分外部 -->
<template>
  <div class="workMent">
    <el-pagination
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
      :current-page="page"
      :page-sizes="[10, 20, 50, 100]"
      :page-size="size"
      layout="total, sizes, prev, pager, next, jumper"
      :total="total"
      :url="url"
    >
    </el-pagination>
  </div>
</template>

<script>
// 引入模块化封装
import { getTableData } from "@/utils/table";
export default {
  // 接收父组件传递过来的值
  props: {
    url: String,
    total: Number,
  },
  data() {
    return {
      // 当前页数
      page: 1,
      // 每页显示多少条
      size: 10,
    };
  },
  // 课堂任务：getTableData() 调用了三次，能不能封装起来（已完成）
  mounted() {
    // 通过接口请求数据(封装后的接口)
    this.getTableData();
  },
  methods: {
    // 每页的条数改变时触发
    handleSizeChange(val) {
      // 每页显示多少条
      this.size = val;
      // 当前页数回到第一页
      this.page = 1;
      // 通过接口请求数据(封装后的接口)
      this.getTableData();
    },
    // 当前页数改变时触发
    handleCurrentChange(val) {
      // 当前页数
      this.page = val;
      // 通过接口请求数据(封装后的接口)
      this.getTableData();
    },
    // 通过接口请求数据(封装后的接口)
    getTableData() {
      // 模块化封装
      getTableData(
        // 传递的值
        this.$parent,
        this.url,
        { page: this.page, size: this.size },
        ["userId", "completed"],
        // 课堂练习：120分
        // { userId: ["实训", "小实训", "就业"], completed: ["已完成", "未完成"] }
        // 课堂练习：150分
        ["实训", "小实训", "就业", "已完成", "未完成"]
      );
    },
  },
};
</script>

<style lang="scss">
.workMent {
  .el-pagination {
    text-align: left;
    margin-top: 20px;
  }
}
</style>

六、权限管理

user

<template>
  <div class="user">
    <el-tree :data="menus" show-checkbox :props="props" ref="tree"> </el-tree>
    <el-button @click="getCheckenNode">通过node获取</el-button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      menus: [],
      props: {
        label: "name",
        children: "children",
      },
    };
  },
  mounted() {
    // 获取路由的值，渲染标签

    // 权限管理和动态路由的思路
    // 根据不同的用户登录上来，返回对应的路由权限菜单
    // 一般情况下可以通过树形控件达成权限的精准控制，根据不同的菜单权限
    // 前端将收集到的菜单数据，发送给后端，后端保存后
    // 用户在进行登录时，就会查询到该用户所拥有的菜单数据，返回前端，在显示对应的数据

    // 动态添加路由使用 router.addRoutes(vue-router3.x版本方法，已废弃)
    // 后续使用：router.addRoute(进行动态路由添加)
    this.menus = [...this.$router.options.routes];
  },
  methods: {
    getCheckenNode() {
      console.log(this.$refs.tree.getCheckedNodes());
    },
  },
};
</script>

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

users

<template>
  <div class="box">

    randoms() {
      // 循环
      for (var i = 0; i < 24; i++) {
        // 把获取到的值赋值给 Number
        this.Number =
          "#" +
          // 下舍入（0-1随机数 乘以 255）转换为16进制
          Math.floor(Math.random() * 255).toString(16) +
          Math.floor(Math.random() * 255).toString(16) +
          Math.floor(Math.random() * 255).toString(16);
        // 追加到 lists 中
        this.lists.push(this.Number);
      }
    },
    add() {

      this.lists = [];
      // 调用封装函数
      this.randoms();
    },
    addcolor(item) {
      // 颜色在 input 框中显示
      this.input = item;
      // 背景色改变
      this.$refs.top.style.backgroundColor = item;
    },
  },
};
</script>

<style lang="scss" scoped>
.box {
