前端開發(fā) =》Vue刷怪小妙招

數(shù)據(jù)字典

• 效果如下

添加路由

• src/router/index.js

  {
    path: '/cmn',
    component: Layout,
    redirect: '/cmn/list',
    name: '數(shù)據(jù)管理',
    alwaysShow: true, //顯示有層次
    meta: { title: '數(shù)據(jù)管理', icon: 'example' },
    children: [
      {
        path: 'list',
        name: '數(shù)據(jù)字典',
        component: () => import('@/views/dict/list'),
        meta: { title: '數(shù)據(jù)字典', icon: 'table' }
      }
    ]
  }

定義api

• src/api/dict.js

import request from '@/utils/request'
export default{
  dictList(id){
    return request({
      url: `/admin/cmn/dict/findChildData/${id}`,
      method: 'get'
    })
  },
}

調(diào)用方法

<script>
import dict from "@/api/dict";

export default {
  data() {
    return {
      list: [],
      dialogImportVisible:false  //設(shè)置彈框是否彈出
    };
  },
  created() {
    this.getDictList(1);
  },
  methods: {
    //數(shù)據(jù)字典列表
    getDictList(id) {
      dict
        .dictList(id)
        .then((response) => {
          this.list = response.data;
        })
        .catch((error) => {});
    },
    //下拉加載數(shù)據(jù)
    getChildrens(tree, treeNode, resolve) {
      dict.dictList(tree.id).then((response) => {
        resolve(response.data);
      });
    },
  },
};
</script>

頁面渲染

<el-table
      :data="list"
      style="width: 100%"
      row-key="id"
      border
      lazy
      :load="getChildrens"
      :tree-props="{ children: 'children', hasChildren: 'hasChildren' }"
    >
      <el-table-column label="名稱" width="230" align="left">
        <template slot-scope="scope">
          <span>{{ scope.row.name }}</span>
        </template>
      </el-table-column>

      <el-table-column label="編碼" width="220">
        <template slot-scope="{ row }">
          {{ row.dictCode }}
        </template>
      </el-table-column>
      <el-table-column label="值" width="230" align="left">
        <template slot-scope="scope">
          <span>{{ scope.row.value }}</span>
        </template>
      </el-table-column>
      <el-table-column label="創(chuàng)建時間" align="center">
        <template slot-scope="scope">
          <span>{{ scope.row.createTime }}</span>
        </template>
      </el-table-column>
    </el-table>

導出

• 組件

    <div class="el-toolbar">
      <div class="el-toolbar-body" style="justify-content: flex-start">
        <el-button type="text" @click="exportData"
          ><i class="fa fa-plus" /> 導出</el-button
        >
        <el-button type="text" @click="importData"
          ><i class="fa fa-plus" /> 導入</el-button
        >
      </div>
    </div>

• 組件接口

 //導出數(shù)據(jù)
    exportData() {
      window.location.href = "http://localhost:8202/admin/cmn/dict/exportData";
    },

導入

• 彈框
• 效果圖
• 組件

   <el-dialog title="導入" :visible.sync="dialogImportVisible" width="480px">
      <el-form label-position="right" label-width="170px">
        <el-form-item label="文件">
          <el-upload
            :multiple="false"
            :on-success="onUploadSuccess"
            :action="'http://localhost:8202/admin/cmn/dict/importData'"
            class="upload-demo"
          >
            <el-button size="small" type="primary">點擊上傳</el-button>
            <div slot="tip" class="el-upload__tip">
              只能上傳xls文件，且不超過500kb
            </div>
          </el-upload>
        </el-form-item>
      </el-form>
      <div slot="footer" class="dialog-footer">
        <el-button @click="dialogImportVisible = false"> 取消 </el-button>
      </div>
    </el-dialog>

• 組件接口

    //數(shù)據(jù)導入
    importData() {
        this.dialogImportVisible = true;  //設(shè)置彈框是否彈出
    },
    //上傳成功調(diào)用的方法
    onUploadSuccess(){
        this.dialogImportVisible = false;  //設(shè)置彈框是否彈出
        this.getDictList(1);
    },

到這里導入導出基本已經(jīng)完善好了，包括列表的編輯、刪除以及添加操作，模糊查詢
