vue后台（五）

一，查看某个spu下的所有sku列表

 

 

 

在elementUI找到el-dialog,表格嵌套dialog

 <el-dialog title="sku列表" :visible.sync="dialogTableVisible" :before-close="handleBeforeClose">
      <el-table :data="skuList">
        <el-table-column property="skuName" label="名称" width="150"></el-table-column>
        <el-table-column property="price" label="价格（元）" width="200"></el-table-column>
        <el-table-column property="weight" label="重量（KG）"></el-table-column>
        <el-table-column label="默认图片">
          <template slot-scope="{row,$index}">
            <img :src="row.skuDefaultImg" alt style="width:80px" />
          </template>
        </el-table-column>
      </el-table>
    </el-dialog>

data() {
    return {
      dialogTableVisible:false,
      skuList:[],
      isShowSkuForm:false,
      isShowSpuForm:false,
      isShowList: true,
      category1Id: "",
      category2Id: "",
      category3Id: "",
      spuList: [],
      page: 1,
      limit: 3,
      total: 0
    };

 

点击查看sku按钮

  <el-button
                type="info"
                icon="el-icon-info"
                size="mini"
                title="查看所有的sku"
                @click="showSkuList(row)"
              ></el-button>

 async showSkuList(row) {
      //点击查看sku显示dialog
      this.dialogTableVisible = true;
      //发请求获取sku列表
      const result = await this.$API.sku.getListBySpuId(row.id);
      if (result.code === 200) {
        this.skuList = result.data;
      }
    },

数据在模板填充

关闭dialog之前清空数据，状态改变

  <el-dialog title="sku列表" :visible.sync="dialogTableVisible" :before-close="handleBeforeClose">
    <el-table :data="skuList">
      <el-table-column property="skuName" label="名称" width="150"></el-table-column>
      <el-table-column property="price" label="价格（元）" width="200"></el-table-column>
      <el-table-column property="weight" label="重量（KG）"></el-table-column>
      <el-table-column label="默认图片">
        <template slot-scope="{row, $index}">
          <img :src="row.skuDefaultImg" alt="" style="width:80px">
        </template>
      </el-table-column>
    </el-table>
    </el-dialog>

// 关闭dialog之前，清空数据
    handleBeforeClose(){
      this.skuList = []
      this.dialogTableVisible = false
    },

 

二，删除某个spu逻辑

2.1，点击删除按钮，利用popconfirm气泡框

 

 

 

 <el-popconfirm   :title="`确定删除${row.spuName}吗？`"  @onConfirm="delteSpu(row)">
               
                <el-button slot="reference"  type="danger"  icon="el-icon-delete"  size="mini"  title="删除spu"></el-button>
              </el-popconfirm>

点击确定按钮，发送请求删除spu

 

 

 

   // 删除某一条spu
    async  delteSpu(row){
      console.log(344)
      const result = await this.$API.spu.remove(row.id)
      if(result.code ===200){
        this.$message.success('删除成功')
        // 重新发送请求
        this.getSpuList(this.spuList >1 ? this.page : this.page-1)
      }else{
        this.$message.error('删除失败')
      }
    },

 

三，点击添加sku按钮，初始化请求数据

<template slot-scope="{ row, $index }">
              <el-button
                type="primary"
                icon="el-icon-plus"
                size="mini"
                title="添加sku"
                @click="showAddSkuForm(row)"
              ></el-button>

在spu父组件中，调用子组件skuForm的initUpdateSkuForm方法，发送三个请求，获取初始化数据

      <skuForm v-show="isShowSkuForm"  ref="sku"></skuForm>
      <spuForm  v-show="isShowSpuForm" @visible="isShowSpuForm =$event"  ref="spu"></spuForm>

js代码

 // 点击添加sku按钮
    showAddSkuForm(spu){
      this.isShowSkuForm =true
      // 获取子组件skuForm，调用他里头的方法，发送四个接口函数，获取数据
      this.$refs.sku.initUpdateSkuForm(spu, this.category1Id, this.category2Id)
    },

子组件skuForm发送请求

 async initAddSkuForm(spu, category1Id, category2Id) {
      this.spu = spu;
      //发送三个请求获取初始化展示所需要的数据

      // /admin/product/attrInfoList/2/13/61   某3级分类下的平台属性列表
      let promise1 = this.$API.attr.getList(
        category1Id,
        category2Id,
        spu.category3Id
      );
      // /admin/product/spuImageList/767
      let promise2 = this.$API.sku.getSpuImageList(spu.id);
      // /admin/product/spuSaleAttrList/767
      let promise3 = this.$API.sku.getSpuSaleAttrList(spu.id);

      const result = await Promise.all([promise1, promise2, promise3]);

      // [{成功结果对象1}，{成功结果对象2}，{成功结果对象3}]
      // let [attrInfoList,spuImageList,spuSaleAttrList] = result

      this.attrInfoList = result[0].data;
      let spuImageList = result[1].data
 
      this.spuSaleAttrList = result[2].data;
    },

 data() {
    return {
      spu: {},
      attrInfoList: [],
      spuImageList: [],
      spuSaleAttrList: []
    };

 

四，skuForm静态页面搭建，（form表单套form表单，form表单套table表单）

 

 

 

<template>
    <el-card>
        <el-form :model="spu" ref="form"  label-width="100px" >
            <el-form-item label="SPU名称">
                {{spu.spuName}}
            </el-form-item>
            <el-form-item label="SKU名称">
                <el-input placeholder="SKU名称"  ></el-input>
                
            </el-form-item>
            <el-form-item label="价格">
               <el-input placeholder="SKU价格"   type="number"></el-input>
            </el-form-item>
            <el-form-item label="SKU重量">
               <el-input placeholder="SKU重量"   type="number"></el-input>
            </el-form-item>
            <el-form-item label="规格描述">
               <el-input placeholder="SKU规格描述"   type="textarea"></el-input>
            </el-form-item>

             <el-form-item label="平台属性">
                 <el-form  label-width="100px" :inline="true">
                     <el-form-item label="内存">
                         <el-select  value="" placeholder="请选择">
                             <el-option  value="">
                                
                             </el-option>
                         </el-select>
                         
                     </el-form-item>
                     <el-form-item label="运行内存">
                         <el-select   value="" placeholder="请选择">
                             <el-option  value="">
                                
                             </el-option>
                         </el-select>
                         
                     </el-form-item>
                 </el-form>   
                 
            </el-form-item>

             <el-form-item label="销售属性">
                 <el-form  label-width="100px" :inline="true">
                     <el-form-item label="选择颜色">
                         <el-select   value="" placeholder="请选择">
                             <el-option  value="">
                                
                             </el-option>
                         </el-select>
                         
                     </el-form-item>
                     <el-form-item label="选择版本">
                         <el-select   value=""  placeholder="请选择">
                             <el-option  value="">
                                
                             </el-option>
                         </el-select>
                         
                     </el-form-item>
                 </el-form>   
                 
            </el-form-item>

            <el-form-item label="规格描述">
               <el-table  border stripe>
                    <el-table-column
                        type="selection"
                        width="55">
                    </el-table-column>
                   <el-table-column label="图片" width="width">
                   </el-table-column>
                    <el-table-column label="名称" width="width">
                   </el-table-column>
                    <el-table-column label="操作" width="width">
                        
                   </el-table-column>
               </el-table>
               
            </el-form-item>

            <el-form-item >
               
               <el-button type="primary" >保存</el-button>
                <el-button >返回</el-button>
            </el-form-item>

           
        </el-form>
        
    </el-card>
</template>

 

五，数据展示及收集数据及图片收集

需要收集的数据

data() {
    return {
      spu: {},
      attrInfoList: [],
      spuImageList: [],
      spuSaleAttrList: [],
      selectImageList:[],
      skuInfo: {
        //父组件传递过来的spu内部获取
        category3Id: "",
        spuId: "",
        tmId: "",

        //收集直接通过v-model获取
        skuName: "",
        skuDesc: "",
        price: "",
        weight: "",

        //下面这些是需要整理得到的
        skuDefaultImg: "",
        skuAttrValueList: [
          // {
          //   attrId: "2",
          //   valueId: "9",
          // },
        ],
        skuSaleAttrValueList: [
          // {
          //   saleAttrValueId: 258,
          // },
        ],
        skuImageList: [
          // {
          //   imgName: "下载 (1).jpg",
          //   imgUrl: "http://47.93.148.192:8080/xxx.jpg",
          //   spuImgId: 337, // 当前Spu图片的id
          //   isDefault: "1", // 默认为"1", 非默认为"0"
          // },
        ],
      },
    };

 

数据渲染

<el-card>
    <el-form :model="spu" ref="form" label-width="100px">
      <el-form-item label="SPU名称">
        {{ spu.spuName }}

          >
            <!-- 把选中的属性值的id和当前选择的属性的id 拼接  收集在当前选择的属性身上attrIdValueId， 
            没有选择的属性身上不会有这个属性的attrIdValueId-->
            <el-select
              v-model="attrInfo.attrIdValueId"
              value=""

            :label="spuSaleAttr.saleAttrName"
            v-for="(spuSaleAttr, index) in spuSaleAttrList"
            :key="spuSaleAttr.id"
          >

        <el-button>返回</el-button>
      </el-form-item>
    </el-form>
  </el-card>

 

六，图片的数据收集

 

 

 

 

 

 数据收集

skuInfo: {
        //父组件传递过来的spu内部获取
        category3Id: "",
        spuId: "",
        tmId: "",

        //收集直接通过v-model获取
        skuName: "",
        skuDesc: "",
        price: "",
        weight: "",

        //下面这些是需要整理得到的
        skuDefaultImg: "",
        skuAttrValueList: [
          // {
          //   attrId: "2",
          //   valueId: "9",
          // },
        ],
        skuSaleAttrValueList: [
          // {
          //   saleAttrValueId: 258,
          // },
        ],
        skuImageList: [
          // {
          //   imgName: "下载 (1).jpg",
          //   imgUrl: "http://47.93.148.192:8080/xxx.jpg",
          //   spuImgId: 337, // 当前Spu图片的id
          //   isDefault: "1", // 默认为"1", 非默认为"0"
          // },
        ],
      },

 

<el-form-item label="图片列表">
        <el-table border stripe :data="spuImageList" @selection-change="handleSelectionChange">
          <el-table-column type="selection" width="55"> </el-table-column>
          <el-table-column label="图片" width="width">
            <template slot-scope="{ row, $index }">
              <img :src="row.imgUrl" alt />
            </template>
          </el-table-column>

 //   选择某个图片，将其赋值一个数组
    handleSelectionChange(val) {
      console.log(val)
      //把选中的图片组成一个数组  赋值给selectImageList
      this.selectImageList = val;
    },

 

点击设为默认按钮，将button变成tag按钮，并且将该isDefault属性变成默认的1，并且将该图片设置默认图片

请求图片数据之前，需要添加isDefault属性

 async initUpdateSkuForm(spu, category1Id, category2Id) {
      this.spu = spu;
      //发送三个请求获取初始化展示所需要的数据

      // /admin/product/attrInfoList/2/13/61   某3级分类下的平台属性列表
      let promise1 = this.$API.attr.getList(
        category1Id,
        category2Id,
        spu.category3Id
      );
      // /admin/product/spuImageList/767
      let promise2 = this.$API.sku.getSpuImageList(spu.id);
      // /admin/product/spuSaleAttrList/767
      let promise3 = this.$API.sku.getSpuSaleAttrList(spu.id);

      const result = await Promise.all([promise1, promise2, promise3]);

      // [{成功结果对象1}，{成功结果对象2}，{成功结果对象3}]
      // let [attrInfoList,spuImageList,spuSaleAttrList] = result

      this.attrInfoList = result[0].data;
      let spuImageList = result[1].data
        //请求数据之前，添加isDefault属性，为非默认的，动态属性 
      spuImageList.forEach(item => item.isDefault = '0')
      this.spuImageList = spuImageList;

      this.spuSaleAttrList = result[2].data;
    }

 

<el-table-column label="操作" width="width"> 
               <template slot-scope="{row,$index}">
              <el-button
                v-if="row.isDefault === '0'"
                type="primary"
                size="mini"
                @click="setDefault(row)"
              >设为默认</el-button>
              <el-tag v-else type="success">默认</el-tag>
            </template>
          </el-table-column>

  //  点击设为默认按钮 
      setDefault(row){
        //所有的图片数组 而不是选中图片数组  因为每个人都有权力成为默认
        this.spuImageList.forEach(item => item.isDefault = '0')
        row.isDefault = '1'
        this.skuInfo.skuDefaultImg = row.imgUrl  //收集默认图片的路径
    },

 

七，保存sku数据的整理，并发送请求

 <el-form-item>
        <el-button type="primary" @click="saveSku">保存</el-button>
        <el-button @click="back">返回</el-button>
      </el-form-item>

js代码

  async saveSku(){
      //获取参数数据
      let {spu,skuInfo,attrInfoList,spuSaleAttrList,selectImageList} = this
      //整理数据
      // 1、整理父带过来的
      skuInfo.category3Id = spu.category3Id
      skuInfo.spuId = spu.id
      skuInfo.tmId = spu.tmId
      // 2、整理没有收集到skuInfo内部的
      //  [
      //    {
      //      id:1,
      //      attrValueList:[
      //        {
      //          id:22,
      //          valueName:''
      //        }
      //      ]
      //    }
      //  ]
      //整理sku的平台属性
      skuInfo.skuAttrValueList = attrInfoList.reduce((pre,item)=>{
        if(item.attrIdValueId){
          let [attrId,valueId] = item.attrIdValueId.split(':')
          pre.push({
            attrId,
            valueId
          })
        }
        return pre
      },[])

      //整理sku的销售属性
      skuInfo.skuSaleAttrValueList = spuSaleAttrList.reduce((pre,item)=>{
        if(item.saleAttrValueId){
          // let {saleAttrValueId} = item
          pre.push({
            saleAttrValueId:item.saleAttrValueId
          })
        }
        return pre
      },[])


      //整理图片
      // selectImageList  目前结构 

      // id:4292
      // imgName:null
      // imgUrl:"http://182.92.128.115:8080/group1/M00/00/31/rBFUDF8mvSKAAg5VAAAkZFM9VUU005.jpg"
      // isDefault:"0"
      // spuId:209


      // 最终结构
      //  {
      //   imgName: "下载 (1).jpg",
      //   imgUrl: "http://47.93.148.192:8080/xxx.jpg",
      //   spuImgId: 337, // 当前Spu图片的id
      //   isDefault: "1", // 默认为"1", 非默认为"0"
      // },

      skuInfo.skuImageList = selectImageList.map(item => ({
        imgName:item.imgName,
        imgUrl:item.imgUrl,
        spuImgId:item.id,
        isDefault:item.isDefault
      }))



      //发送请求
      const result = await this.$API.sku.addUpdate(skuInfo)
      
      if(result.code === 200){
        //请求成功
        this.$message.success('保存sku成功')
        // 返回到spu商品页
        this.$emit('visible',false)
        //并不需要去重新请求spu的列表，因为sku添加和spu列表没关系
        //清空sku添加当前组件的数据
        this.resetData()

      }else{
        //请求失败
        this.$message.error('保存sku失败')
      }
    },

父组件spu

 <skuForm v-show="isShowSkuForm"  ref="sku" @visible="isShowSkuForm =$event"></skuForm>
      <spuForm  v-show="isShowSpuForm" @visible="isShowSpuForm =$event"  ref="spu"></spuForm>
    </el-card>

 

resetData(){
      this.spu = {}
      this.attrInfoList = []
      this.spuImageList = []
      this.spuSaleAttrList = []
      this.selectImageList =[]
      this.skuInfo = {
        //父组件传递过来的spu内部获取
        category3Id: "",
        spuId: "",
        tmId: "",

        //收集直接通过v-model获取
        skuName: "",
        skuDesc: "",
        price: "",
        weight: "",

        //下面这些是需要整理得到的
        skuDefaultImg: "",
        skuAttrValueList: [
          // {
          //   attrId: "2",
          //   valueId: "9",
          // },
        ],
        skuSaleAttrValueList: [
          // {
          //   saleAttrValueId: 258,
          // },
        ],
        skuImageList: [
          // {
          //   imgName: "下载 (1).jpg",
          //   imgUrl: "http://47.93.148.192:8080/xxx.jpg",
          //   spuImgId: 337, // 当前Spu图片的id
          //   isDefault: "1", // 默认为"1", 非默认为"0"
          // },
        ],
      }
    },

 

八，点击返回按钮

  //点击返回按钮操作
    back(){
      this.$emit('visible',false)
      this.resetData()
    },

 

九，三级分类列表可操作性

在spu组件中监视

 watch:{
    isShowSpuForm(newVal){
      this.isShowList = !newVal
    },

    isShowSkuForm(newVal){
      this.isShowList = !newVal
    }
  },
