基础用法

在 el-breadcrumb 中使用 el-breadcrumb-item 标签表示从首页开始的每一级。 该组件接受一个 String 类型的参数 separator来作为分隔符。 默认值为 ‘/’。

<template>
  <el-breadcrumb separator="/">
    <el-breadcrumb-item :to="{ path: '/' }">homepage</el-breadcrumb-item>
    <el-breadcrumb-item>
      <a href="/">promotion management</a>
    </el-breadcrumb-item>
    <el-breadcrumb-item>promotion list</el-breadcrumb-item>
    <el-breadcrumb-item>promotion detail</el-breadcrumb-item>
  </el-breadcrumb>
</template>

代码

<script setup lang="ts" name="Category">
    import { getCategoryAPI } from '@/apis/category';
    import { onMounted, ref } from 'vue';
    import { useRoute } from 'vue-router';

    const categoryData = ref({})
    const route = useRoute()
    const getCategory = async () => {
        const res = await getCategoryAPI(route.params.id);
        console.log(res);
        categoryData.value = res.data.result;
        console.log(categoryData.value);
    }
    onMounted(() => getCategory())

</script>

<template>
    <div class="top-category">
