Vue2实践项目五：学生列表查询和数据转换，删除

api.js添加接口

//学生列表查询接口
export function students(params){
  return service({
    method: 'get',
    url: '/students',
    params
  })
}
  //学生列表删除接口
export function studentDel(id){
  return service({
    method: 'delete',
    url: `/students/${id}`
  })
}

查询列表、删除、分页、重置、数据转换

<template>

      <el-form-item label="姓名">

      <el-form-item>
        <el-button type="primary" @click="find()">查询</el-button>
      </el-form-item>
      <el-form-item>
        <el-button type="primary" @click="reset()">重置</el-button>
      </el-form-item>
    </el-form>
