在线教育项目-day04【讲师列表查询功能】

一、讲师列表功能

1.更改路由

点击index.js

 

 

2.更改内容

然后在view下新建文件夹叫edu，再新建一个文件夹叫teacher，创建两个vue文件

并且更改路由的index.js

 接下来我们在list.vue和save.vue中添加信息，看看是否正确

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

成功显示：

 

 3.更改api

在api文件中添加，如图文件

import request from '@/utils/request'
export default{
    //1.讲师列表条件（分页查询）
    getTeacherListPage(current,limit,teacherQuery){
        return request({
            url: `/eduservice/edu-teacher/PageFindCondition/${current}/${limit}`,
            method: 'post',
            //data表示把对象转换成json进行传递
            data: teacherQuery
          })
    }
}

4. 书写list.vue

<template>
  <div class="app-container">
    讲师列表
  </div>
</template>
<script>
import teacher from '@/api/teacher/teacher'
export default {
    //书写核心代码
    data(){//d定义变量
        return {
            list:null,//查询之后接口返回集合
            page:1,//当前页
            limit:10,//每页记录数
            total:0,
            teacherQuery:{}//条件封装对象
        }
    },
    created(){//页面渲染前执行
        this.getList()
    },
    methods:{
        getList(){
            teacher.getTeacherListPage(this.page,this.limit,this.teacherQuery)
                .then(response=>{
                    console.log(response)
                })//请求成功
                .catch(error=>{
                    console.log(error)
                })//请求失败
        }
    }

}
</script>

 5.测试

 可以看到我们前端拿到了数据

6.完善页面

加上索引、表格、分页，

<template>
  <div class="app-container">
    讲师列表
     <!--查询表单-->
    <el-form :inline="true" class="demo-form-inline">
      <el-form-item>
        <el-input v-model="teacherQuery.name" placeholder="讲师名"/>
      </el-form-item>

      <el-form-item>
        <el-select v-model="teacherQuery.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="teacherQuery.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="teacherQuery.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="getList()">查询</el-button>
      <el-button type="default" @click="resetData()">清空</el-button>
    </el-form>
     <!-- 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">

            <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>
    
   <!-- 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="getList"
    />

  </div>
</template>
<script>
import teacher from '@/api/teacher/teacher'
export default {
    //书写核心代码
    data(){//d定义变量
        return {
            list:null,//查询之后接口返回集合
            page:1,//当前页
            limit:6,//每页记录数
            total:0,
            teacherQuery:{}//条件封装对象
        }
    },
    created(){//页面渲染前执行
        this.getList()
    },
    methods:{
        getList(page=1){
            this.page=page
            teacher.getTeacherListPage(this.page,this.limit,this.teacherQuery)
                .then(response=>{
                    this.list=response.data.rows
                    this.total=response.data.total
                    console.log(this.list)
                    console.log(this.total)
                })//请求成功
                .catch(error=>{

    }

}
</script>
