# 一 定义 api 模块 #

import request from '@/utils/request'
    
    export default {
        // 分页查询
        getHospitalList(current, limit, searchObj) {
            return request({
                url: `/admin/hospital/findPageHospital/${current}/${limit}`,
                method: 'post',
                data: searchObj // 使用 json 进行参数传递
            })
        },
        // 单条删除医院
        deleteHospital(id) {
            return request({
                url: `/admin/hospital/${id}`,
                method: 'delete'
            })
        },
        // 批量删除医院
        removeHospitals(idList) {
            return request({
                url: `/admin/hospital/batchRemove`,
                method: 'delete',
                data: idList
            })
        }
    }

# 二 页面部分 #

<template>
      <div class="app-container">
        
        <el-form :inline="true" class="demo-form-inline">
          <el-form-item>

          <el-form-item>
            <el-input v-model="searchObj.province" placeholder="省" />
          </el-form-item>
          <el-form-item>
            <el-input v-model="searchObj.city" placeholder="市" />

        <div>
          <el-button type="danger" size="mini" @click="removeRows()">批量删除</el-button>
        </div>
