vue+mockjs模拟数据分页功能、新增功能、编辑功能、删除功能

Mockjs模拟数据,实现增删改查

1、安装mockjs

npm install mockjs --save-dev

2、mock.js文件

// mock.js 文件
import Mock from mockjs // 引入mockjs
const Random = Mock.Random // Mock.Random 是一个工具类,用于生成各种随机数据
const dataList = [] // 用于接受生成数据的数组
for (let i = 0; i < 26; i++) { // 可自定义生成的个数
  const template = {
    id: i, // id
    Name: Random.name(), // 生成姓名
    Address: Random.province() // 生成地址
  }
  dataList.push(template)
}

// 模拟分页
Mock.mock(http://localhost:8080/api/list, post, (params) => {
  var listQuery = JSON.parse(params.body)
  var pageIndex = (listQuery.page - 1) * listQuery.pageSize
  var [index, size, total] = [pageIndex, listQuery.pageSize, dataList.length]
  var newDataList = dataList.slice(index * size, (index + 1) * size)
  return {
    code: 200,
    message: success,
    data: {
      listQuery: listQuery,
      tableData: newDataList,
      tableHead: [{ column: id, columen_comment: 用户id }, { column: Name, columen_comment: 姓名 }, { column: Address, columen_comment: 地址 }],
      total: total
    }
  }
})

// 模拟新增数据
Mock.mock(http://localhost:8080/api/add, post, (params) => {
  var data = JSON.parse(params.body)
  data.id = dataList.length
  dataList.push(data)
  return {
    code: 200,
    message: success
  }
})

// 模拟删除数据
Mock.mock(http://localhost:8080/api/delete, post, (params) => {
  var data = JSON.parse(params.body)
  dataList.splice(data.id, 1)
  return {
    code: 200,
    message: success
  }
})

// 模拟修改数据
Mock.mock(http://localhost:8080/api/update, post, (params) => {
  var data = JSON.parse(params.body)
  /* dataList.map((item) => {
    if (item.id === data.id) {
      return data
    } else { return item }
  }) */
  for (var i in dataList) {
    if (dataList[i].id === data.id) { // 在数组arr里找到这个id
      dataList[i] = data
    }
  }
  return {
    code: 200,
    message: success,
    data: data
  }
})

3、在使用到地方引入

//引入
require(@/utils/mock.js)
mounted() {
    this.test()
  },
methods: {
    async test() {
      await axios.post(http://localhost:8080/api/list, { page: 1, pageSize: 30 }).then(res => {
        console.log(res)
      })
      await axios.post(http://localhost:8080/api/add, { Name: lijn, Address: fhhsdf }).then(res => {
        console.log(res)
      })
      await axios.post(http://localhost:8080/api/delete, { id: 25 }).then(res => {
        console.log(res)
      })
      await axios.post(http://localhost:8080/api/update, { id: 26, Name: ljc, Address: 广东省 }).then(res => {
        console.log(res)
      })
      await axios.post(http://localhost:8080/api/list, { page: 1, pageSize: 30 }).then(res => {
        console.log(res)
      })
      await axios.post(http://localhost:8080/api/list, { page: 1, pageSize: 30 }).then(res => {
        console.log(res)
      })
    }
 }
