    params:{
   
      id
    }

<script setup>
import {

import {
    onMounted, ref } from 'vue'
import {
    useRoute } from 'vue-router'
// 获取面包屑导航数据

二级分类商品列表实现

在这里插入图片描述

基础参数获取基础列表

在这里插入图片描述
准备接口

/**
 * @description: 获取导航数据
 * @data { 
     categoryId: 1005000 ,
     page: 1,
     pageSize: 20,
     sortField: 'publishTime' | 'orderNum' | 'evaluateNum'
   } 
 * @return {*}
 */
export const getSubCategoryAPI = (data) => {
   
  return request({
   
    url:'/category/goods/temporary',
    method:'POST',
    data
  })
}

获取数据列表

<script setup>
  
// 获取基础列表数据渲染
const goodList = ref([])
const reqData = ref({
   
  categoryId: route.params.id,
  page: 1,
  pageSize: 20,
  sortField: 'publishTime'
})
  
const getGoodList = async () => {
   
  const res = await getSubCategoryAPI(reqData.value)
  console.log(res)
  goodList.value = res.result.items
}
  
onMounted(() => getGoodList())

    <!-- 商品列表-->
        <GoodsItem v-for="goods in goodList" :goods="goods" :key="goods.id" />
列表筛选功能实现

在这里插入图片描述
核心逻辑
点击tab，切换筛选条件参数sortField，重新发送列表请求
在这里插入图片描述
列表筛选实现

<script setup>
// tab切换回调
const tabChange = () => {
   
  console.log('tab切换了', reqData.value.sortField)
  reqData.value.page = 1
  getGoodList()
}
</script>
<template>
  <el-tabs v-model="reqData.sortField" @tab-change="tabChange">
    <el-tab-pane label="最新商品" name="publishTime"></el-tab-pane>
    <el-tab-pane label="最高人气" name="orderNum"></el-tab-pane>
    <el-tab-pane label="评论最多" name="evaluateNum"></el-tab-pane>
  </el-tabs>
</template>
列表无限加载功能实现

在这里插入图片描述
核心实现逻辑
使用elementPlus提供的v-infinite-scroll指令监听是否满足触底条件，满足加载条件时让页数参数加一获取下一页数据，做新老数据拼接渲染

基础思路

  1. 触底条件满足之后 page++，拉取下一页数据
  2. 新老数据做数组拼接
  3. 判断是否已经全部加载完毕，停止监听

// 获取面包屑导航数据

const route = useRoute()
const getCategoryData = async () => {
   
  const res = await getCategoryFilterAPI(route.params.id)
  categoryData.value = res.result
}
onMounted(() => getCategoryData())

// 获取基础列表数据渲染

  const res = await getSubCategoryAPI(reqData.value)

// tab切换回调
const tabChange = () => {
   
  console.log('tab切换了', reqData.value.sortField)
  reqData.value.page = 1
  getGoodList()
}

// 加载更多
const disabled = ref(false)
const load = async () => {
   
  console.log('加载更多数据咯')
  // 获取下一页的数据
  reqData.value.page++
  const res = await getSubCategoryAPI(reqData.value)
  goodList.value = [...goodList.value, ...res.result.items]
  // 加载完毕 停止监听
  if (res.result.items.length === 0) {
   
    disabled.value = true

二级分类定制路由scrollBehavior

定制路由行为解决什么问题
在不同路由切换的时候，可以自动滚动到页面的顶部，而不是停留在原先的位置
在这里插入图片描述

// createRouter：创建router实例对象
// createWebHistory：创建history模式的路由

import {
    createRouter, createWebHistory } from 'vue-router'
import Login from '@/views/Login/index.vue'
import Layout from '@/views/Layout/index.vue'
import Home from '@/views/Home/index.vue'
import Category from '@/views/Category/index.vue'
import SubCategory from '@/views/SubCategory/index.vue'


const router = createRouter({
   
  history: createWebHistory(import.meta.env.BASE_URL),
  // path和component对应关系的位置
  routes: [
    {
   
      path: '/',
      component: Layout,
      children: [
        {
   
          path: '',
          component: Home
        },
        {
   
          path: 'category/:id',
          component: Category
        },
        {
   
          path: 'category/sub/:id',
          component: SubCategory
        },
      ]
    },
    {
   
      path: '/login',
      component: Login
    }
  ],
  // 路由滚动行为定制
  scrollBehavior () {
   
    return {
   
      top: 0
    }
  }
})

export default router
