Vue 商品分类模块(实现参数的增删改)

分类参数之级联选择器

elemetui Alert警告

只允许为第三季分类设置相关参数，因为第三级才会涉及到具体的商品,商品会包含一些参数

<template>
  <div>

获取参数列表数据

elementui Tabs 标签页
activeName绑定的是你点击的是第几个，点击用户管理activeName就是first

 <el-tabs v-model="activeName" @tab-click="handleClick">
    <el-tab-pane label="用户管理" name="first">用户管理</el-tab-pane>
    <el-tab-pane label="配置管理" name="second">配置管理</el-tab-pane>
    <el-tab-pane label="角色管理" name="third">角色管理</el-tab-pane>
    <el-tab-pane label="定时任务补偿" name="fourth">定时任务补偿</el-tab-pane>
  </el-tabs>

<!-- tabs标签页-->
      <el-tabs v-model="activeName" @tab-click="handleClick">
        <el-tab-pane label="动态参数" name="many">
            <el-button type="primary" size="mini" :disabled="true">添加参数</el-button>
            <el-table>
                <el-table-column label="序号" type="index"></el-table-column>
                <el-table-column label="参数名称"></el-table-column>
                <el-table-column label="操作"></el-table-column>

        </el-tab-pane>
        <el-tab-pane label="静态属性" name="only">配置管理</el-tab-pane>
      </el-tabs>

//级联选择器选中的id数组
      selectdKeys: [],
      // 激活第几个标签页
      activeName:'many',

// 获取分类参数的数据
  async getParamsData(){
      // 判断是否选中三级分类,如果未选中则重新选中
      if(this.selectdKeys.length!==3){
          this.selectdKeys=[]
          return
      }
      // 根据所选分类获取动态参数或者静态属性                    三级分类的id
      const { data: res } = await this.$http.get(`categories/${this.cateId}/attributes`,{
          params:{
              sel:this.activeName
          }
      })
      if(res.meta.status !== 200){
          return this.$message.error('获取参数列表失败')
      }
      console.log(res.data)
  },
  
  },
  computed:{
      // 当前选中的三级分类的id
      cateId(){
          return this.selectdKeys.length===3 ? this.selectdKeys[2] : null
      }
  }

展示参数列表

这里需要注意的是点击标签activeName会获取到name的属性
根据该属性的不同会向后端传递不同的参数，以表示请求的是参数列表还是属性列表

<!-- tabs标签页-->
      <el-tabs v-model="activeName" @tab-click="handleClick">

      const { data: res } = await this.$http.get(`categories/${this.cateId}/attributes`,{
          params:{
              sel:this.activeName
          }
      })
      if(res.meta.status !== 200){
          return this.$message.error('获取参数列表失败')
      }
      this.paramsData = res.data
  },
  },
  
  computed:{
      // 当前选中的三级分类的id
      cateId(){
          return this.selectdKeys.length===3 ? this.selectdKeys[2] : null
      },
      // 是否禁用按钮
      btnDisabled(){
          return this.selectdKeys.length ===3 ? false : true
      }
  },

需要注意的一点点击清除分类功能,实际上下面的数据还会存在

实现添加参数功能

<el-button type="primary" size="mini" :disabled="btnDisabled" @click="addDialogVisible=true">添加参数</el-button>

<!-- 添加对话框-->
    <el-dialog :title="'添加' + title" :visible.sync="addDialogVisible" width="50%" @close="addDialogClosed">
      <el-form :model="addForm" :rules="addFormRules" ref="addFormRef" label-width="100px" >
        <el-form-item :label="title" prop="addr_name">
          <el-input v-model="addForm.attr_name"></el-input>
        </el-form-item>
      </el-form>
      <span slot="footer" class="dialog-footer">
        <el-button @click="addDialogVisible = false">取 消</el-button>
        <el-button type="primary" @click="addParams()">确 定</el-button>
      </span>
    </el-dialog>

// 监听添加对话框的关闭事件
    addDialogClosed() {
        this.$refs.addFormRef.resetFields()
    },
    // 添加参数
    addParams(){
        this.$refs.addFormRef.validate(async valid=>{
            if(!valid){
                return
            }
            const{data:res}=await this.$http.post(`categories/${this.cateId}/attributes`,{
                attr_name:this.addForm.attr_name,
                attr_sel:this.activeName
            })
            if(res.meta.status !== 201){
                return this.$message.error('添加参数失败')
            }
            this.addDialogVisible=false
            this.getParamsData()
            this.$message.success('添加参数成功')
        })
    }

实现删除参数功能

elementui messageBox

// 删除参数
    removeParams(id){
        this.$confirm('确定要删除该参数吗?', '提示', {
          confirmButtonText: '确定',
          cancelButtonText: '取消',
          type: 'warning'
        }).then(async() => {
          const {data:res} = await this.$http.delete(`categories/${this.cateId}/attributes/${id}`)
            if(res.meta.status !== 200){
                return this.$message.error('删除参数失败')
            }
            this.getParamsData()
            this.$message.success('删除参数成功')
        }).catch(() => {
          this.$message({
            type: 'info',
            message: '已取消删除'
          });          
        });
    }

<el-button type="warning" icon="el-icon-delete" size="mini" @click="removeParams(scope.row.attr_id)">删除</el-button>

实现修改参数功能

 <!-- 修改对话框-->
    <el-dialog :title="'修改' + title" :visible.sync="editDialogVisible" width="50%" @close="editDialogClosed">
      <el-form :model="editForm" :rules="editFormRules" ref="editFormRef" label-width="100px" >
        <el-form-item :label="title" prop="attr_name">
          <el-input v-model="editForm.attr_name"></el-input>
        </el-form-item>
      </el-form>
      <span slot="footer" class="dialog-footer">
        <el-button @click="editDialogVisible = false">取 消</el-button>
        <el-button type="primary" @click="editParams()">确 定</el-button>
      </span>
    </el-dialog>

 // 编辑参数对话框
      editDialogVisible:false,
      editForm:{},
      editFormRules:{
          attr_name: [
            { required: true, message: '请输入参数名称', trigger: 'blur' },
          ],
      }

// 显示编辑对话框
    async showEditDialog(id){
        const {data:res} = await this.$http.get(`categories/${this.cateId}/attributes/${id}`,{
            params:{
                attr_sel:this.activeName
            }
        })
        if(res.meta.status !== 200){
            return this.$message.error('查询参数失败')
        }
        this.editForm = res.data
        this.editDialogVisible = true
    },
    // 监听修改对话框的关闭事件
    editDialogClosed(){
        this.$refs.editFormRef.resetFields()
    },
    // 修改参数
    editParams(){
        this.$refs.editFormRef.validate(async valid =>{
            if(!valid){
                return
            }
            const {data:res} = await this.$http.put(`categories/${this.cateId}/attributes/${this.editForm.attr_id}`,{
                attr_name:this.editForm.attr_name,
                attr_sel:this.activeName,
                attr_vals:this.editForm.attr_vals
            })
            if(res.meta.status !== 200){
                return this.$message.error('修改参数名称失败')
            }
            this.editDialogVisible=false
            this.getParamsData()
            this.$message.success('修改参数名称成功!')

        })
    }
