讲师管理列表组件

# 一、分页列表

# 1、定义api

创建文件 src/api/edu/teacher.js

import request from '@/utils/request'

const api_name = '/admin/edu/teacher'
export default {

  getPageList(page, limit, searchObj) {
    return request({
      url: `${api_name}/${page}/${limit}`,
      method: 'get',
      params: searchObj
    })
  }
}

# 2、初始化vue组件

src/views/edu/teacher/list.vue

<template>
  <div class="app-container">
    讲师列表
  </div>
</template>

<script>
import teacher from '@/api/edu/teacher'
export default {

  data() {// 定义数据
      return {}
  },
    
  created() { // 当页面加载时获取数据
    this.fetchData()
  },
    
  methods: {
    fetchData() { // 调用api层获取数据库中的数据
      console.log('加载列表')
    }
  }
}
</script>

3、定义data

  data() {
    return {
      listLoading: true, // 是否显示loading信息
      list: null, // 数据列表
      total: 0, // 总记录数
      page: 1, // 页码
      limit: 10, // 每页记录数
      searchObj: {}// 查询条件
    }
  },

# 4、定义methods

  methods: {
    fetchData(page = 1) { // 调用api层获取数据库中的数据
      console.log('加载列表')
      this.page = page
      this.listLoading = true
      teacher.getPageList(this.page, this.limit, this.searchObj).then(response => {
        // debugger 设置断点调试
        if (response.success === true) {
          this.list = response.data.rows
          this.total = response.data.total
        }
        this.listLoading = false
      })
    }
  }

# 5、表格渲染

    <!-- 表格 -->
    <el-table
      v-loading="listLoading"
      :data="list"
      element-loading-text="数据加载中"
      border
      fit
      highlight-current-row>

      <el-table-column
        label="序号"
        width="70"
        align="center">
        <template slot-scope="scope">
          {{ (page - 1) * limit + scope.$index + 1 }}
        </template>
      </el-table-column>

      <el-table-column prop="name" label="名称" width="80" />

      <el-table-column label="头衔" width="80">
        <template slot-scope="scope">
          {{ scope.row.level===1?'高级讲师':'首席讲师' }}
        </template>
      </el-table-column>

      <el-table-column prop="intro" label="资历" />

      <el-table-column prop="gmtCreate" label="添加时间" width="160"/>

      <el-table-column prop="sort" label="排序" width="60" />

      <el-table-column label="操作" width="200" align="center">
        <template slot-scope="scope">
          <router-link :to="'/edu/teacher/edit/'+scope.row.id">
            <el-button type="primary" size="mini" icon="el-icon-edit">修改</el-button>
          </router-link>
          <el-button type="danger" size="mini" icon="el-icon-delete" @click="removeDataById(scope.row.id)">删除</el-button>
        </template>
      </el-table-column>
    </el-table>

6、分页组件

   <!-- 分页 -->
    <el-pagination
      :current-page="page"
      :page-size="limit"
      :total="total"
      style="padding: 30px 0; text-align: center;"
      layout="total, prev, pager, next, jumper"
      @current-change="fetchData"
    />

7、顶部查询表单

注意：

element-ui的 date-picker组件默认绑定的时间值是默认世界标准时间，和中国时间差8小时

设置 value-format="yyyy-MM-dd HH:mm:ss" 改变绑定的值

    <!--查询表单-->
    <el-form :inline="true" class="demo-form-inline">
      <el-form-item>
        <el-input v-model="searchObj.name" placeholder="讲师名"/>
      </el-form-item>

      <el-form-item>
        <el-select v-model="searchObj.level" clearable placeholder="讲师头衔">
          <el-option :value="1" label="高级讲师"/>
          <el-option :value="2" label="首席讲师"/>
        </el-select>
      </el-form-item>

      <el-form-item label="添加时间">
        <el-date-picker
          v-model="searchObj.begin"
          type="datetime"
          placeholder="选择开始时间"
          value-format="yyyy-MM-dd HH:mm:ss"
          default-time="00:00:00"
        />
      </el-form-item>
      <el-form-item>
        <el-date-picker
          v-model="searchObj.end"
          type="datetime"
          placeholder="选择截止时间"
          value-format="yyyy-MM-dd HH:mm:ss"
          default-time="00:00:00"
        />
      </el-form-item>

      <el-button type="primary" icon="el-icon-search" @click="fetchData()">查询</el-button>
      <el-button type="default" @click="resetData()">清空</el-button>
    </el-form>

清空方法

resetData() {
    this.searchObj = {}
    this.fetchData()
}

# 8、测试

# 二、删除

# 1、定义api

src/api/edu/teacher.js

removeById(teacherId) {
    return request({
        url: `${api_name}/${teacherId}`,
        method: 'delete'
    })
}

# 2、定义methods

src/views/edu/teacher/list.vue

使用MessageBox 弹框组件

removeDataById(id) {
    // debugger
    // console.log(memberId)
    this.$confirm('此操作将永久删除该记录, 是否继续?', '提示', {
        confirmButtonText: '确定',
        cancelButtonText: '取消',
        type: 'warning'
    }).then(() => {
        return teacher.removeById(id)
    }).then(() => {
        this.fetchData()
        this.$message({
            type: 'success',
            message: '删除成功!'
        })
    }).catch((response) => { // 失败
        if (response === 'cancel') {
            this.$message({
                type: 'info',
                message: '已取消删除'
            })
        } else {
            this.$message({
                type: 'error',
                message: '删除失败'
            })
        }
    })
}
