一、场景效果

二、图标

将图标放到src/assets/icons文件夹中

三、组件封装

在src/components文件夹下新建SizeSelect文件夹，并在SizeSelect文件夹下新建index.vue

<script setup lang="ts">
import { ref } from 'vue';
import { ElMessage } from 'element-plus';

import { useAppStore } from '@/store/modules/app';
import SvgIcon from '@/components/SvgIcon/index.vue';

const appStore = useAppStore();

const sizeOptions = ref([
  { label: '默认', value: 'default' },
  { label: '大型', value: 'large' },
  { label: '小型', value: 'small' }
]);

function handleSizeChange(size: string) {
  appStore.changeSize(size);
  ElMessage.success('切换布局大小成功');
}
</script>

<template>
  <el-dropdown trigger="click" @command="handleSizeChange">
    <div class="cursor-pointerw-[40px] h-[50px] leading-[50px] text-center">
      <svg-icon icon-class="size" />
    </div>
    <template #dropdown>
      <el-dropdown-menu>
        <el-dropdown-item
          v-for="item of sizeOptions"
          :key="item.value"
          :disabled="appStore.size == item.value"
          :command="item.value"
        >
          {{ item.label }}
        </el-dropdown-item>
      </el-dropdown-menu>
    </template>
  </el-dropdown>
</template>

四、使用案例

<!--src/App.vue-->
<script setup lang="ts">
import SizeSelect from '@/components/SizeSelect/index.vue'
</script>

<template>
  <div>
    <size-select></size-select>
  </div>
