# 今日目标★

  1. 完成商品添加
  2. 完成订单列表
  3. 完成数据统计展示

# 添加商品

# 完成图片上传

使用upload组件完成图片上传 在element.js中引入upload组件,并注册 因为upload组件进行图片上传的时候并不是使用axios发送请求 所以,我们需要手动为上传图片的请求添加token,即为upload组件添加headers属性

//在页面中添加upload组件,并设置对应的事件和属性
<el-tab-pane label="商品图片" name="3">
  <!-- 商品图片上传
  action:指定图片上传api接口
  :on-preview : 当点击图片时会触发该事件进行预览操作,处理图片预览
  :on-remove : 当用户点击图片右上角的X号时触发执行
  :on-success:当用户点击上传图片并成功上传时触发
  list-type :设置预览图片的方式
  :headers :设置上传图片的请求头 -->
  <el-upload :action="uploadURL" :on-preview="handlePreview" :on-remove="handleRemove" :on-success="handleSuccess" list-type="picture" :headers="headerObj">
    <el-button size="small" type="primary">点击上传</el-button>
  </el-upload>
</el-tab-pane>
//在el-card卡片视图下面添加对话框用来预览图片
<!-- 预览图片对话框 -->
<el-dialog title="图片预览" :visible.sync="previewVisible" width="50%">
  <img :src="previewPath" class="previewImg" />
</el-dialog>

//在data中添加数据
data(){
  return {
    ......
    //添加商品的表单数据对象
    addForm: {
      goods_name: '',
      goods_price: 0,
      goods_weight: 0,
      goods_number: 0,
      goods_cat: [],
      //上传图片数组
      pics: []
    },
    //上传图片的url地址
    uploadURL: 'http://127.0.0.1:8888/api/private/v1/upload',
    //图片上传组件的headers请求头对象
    headerObj: { Authorization: window.sessionStorage.getItem('token') },
    //保存预览图片的url地址
    previewPath: '',
    //控制预览图片对话框的显示和隐藏
    previewVisible:false
  }
},
//在methods中添加事件处理函数
methods:{
  .......
  handlePreview(file) {
    //当用户点击图片进行预览时执行,处理图片预览
    //形参file就是用户预览的那个文件
    this.previewPath = file.response.data.url
    //显示预览图片对话框
    this.previewVisible = true
  },
  handleRemove(file) {
    //当用户点击X号删除时执行
    //形参file就是用户点击删除的文件
    //获取用户点击删除的那个图片的临时路径
    const filePath = file.response.data.tmp_path
    //使用findIndex来查找符合条件的索引
    const index = this.addForm.pics.findIndex(item => item.pic === filePath)
    //移除索引对应的图片
    this.addForm.pics.splice(index, 1)
  },
  handleSuccess(response) {
    //当上传成功时触发执行
    //形参response就是上传成功之后服务器返回的结果
    //将服务器返回的临时路径保存到addForm表单的pics数组中
    this.addForm.pics.push({ pic: response.data.tmp_path })
  }
}

# 使用富文本插件

想要使用富文本插件vue-quill-editor,就必须先从依赖安装该插件 引入并注册vue-quill-editor,打开main.js,编写如下代码

//导入vue-quill-editor(富文本编辑器)
import VueQuillEditor from 'vue-quill-editor'
//导入vue-quill-editor的样式
import 'quill/dist/quill.core.css'
import 'quill/dist/quill.snow.css'
import 'quill/dist/quill.bubble.css'
......

//全局注册富文本组件
Vue.use(VueQuillEditor)

使用富文本插件vue-quill-editor

<!-- 富文本编辑器组件 -->
<el-tab-pane label="商品内容" name="4">
  <!-- 富文本编辑器组件 -->
  <quill-editor v-model="addForm.goods_introduce"></quill-editor>
  <!-- 添加商品按钮 -->
  <el-button type="primary" class="btnAdd">添加商品</el-button>
</el-tab-pane>

//在数据中添加goods_introduce
//添加商品的表单数据对象
addForm: {
  goods_name: '',
  goods_price: 0,
  goods_weight: 0,
  goods_number: 0,
  goods_cat: [],
  //上传图片数组
  pics: [],
  //商品的详情介绍
  goods_introduce:''
}
//在global.css样式中添加富文本编辑器的最小高度
.ql-editor{
    min-height: 300px;
}
//给添加商品按钮添加间距
.btnAdd{
  margin-top:15px;

# 完成商品添加

完成添加商品的操作 在添加商品之前,为了避免goods_cat数组转换字符串之后导致级联选择器报错,我们需要打开vue控制条,点击依赖,安装lodash,把addForm进行深拷贝

//打开Add.vue,导入lodash
<script>
//官方推荐将lodash导入为_
import _ from 'lodash'

//给添加商品按钮绑定点击事件
<!-- 添加商品按钮 -->
<el-button type="primary" class="btnAdd" @click="add">添加商品</el-button>
//编写点击事件完成商品添加
add(){
  this.$refs.addFormRef.validate(async valid=>{
    if(!valid) return this.$message.error("请填写必要的表单项!")

    //将addForm进行深拷贝,避免goods_cat数组转换字符串之后导致级联选择器报错
    const form = _.cloneDeep(this.addForm)
    //将goods_cat从数组转换为"1,2,3"字符串形式
    form.goods_cat = form.goods_cat.join(",")
    //处理attrs数组,数组中需要包含商品的动态参数和静态属性
    //将manyTableData(动态参数)处理添加到attrs
    this.manyTableData.forEach(item=>{
      form.attrs.push({ attr_id:item.attr_id, attr_value:item.attr_vals.join(" ") }) 
    })
    //将onlyTableData(静态属性)处理添加到attrs
    this.onlyTableData.forEach(item=>{
      form.attrs.push({ attr_id:item.attr_id, attr_value:item.attr_vals }) 
    })

    //发送请求完成商品的添加,商品名称必须是唯一的
    const {data:res} = await this.$http.post('goods',form)
    if(res.meta.status !== 201){
      return this.$message.error('添加商品失败')
    }
    this.$message.success('添加商品成功')
    //编程式导航跳转到商品列表
    this.$router.push('/goods')
  })
}
</script>

# 制作省市区县联动

打开今天的资料,找到素材文件夹,复制citydata.js文件到components/order文件夹中 然后导入citydata.js文件

具体代码如下:

//给修改地址按钮添加点击事件

//添加修改地址对话框,在卡片视图下方添加
<!-- 修改地址对话框 -->

    <!-- 添加表单 -->

# 制作物流进度对话框

因为我们使用的是element-ui中提供的Timeline组件,所以需要导入并注册组件 打开element.js,编写代码会进行导入和注册

} from 'element-ui'

Vue.use(Timeline)
Vue.use(TimelineItem)

  { path: "/welcome", component: Welcome },
  { path: "/users", component: Users },
  { path: "/rights", component: Rights },
  { path: "/roles", component: Roles  },
  { path: "/categories", component: Cate  },
  { path: "/params", component: Params  },
  { path: "/goods", component: GoodList  },
  { path: "/goods/add", component: GoodAdd  },
