vue3封装Loading

前言

因为后台管理，总要写很多loading状态的变量，然后控制开启和关闭。。我个人很讨厌写这种重复的代码。。所以为了少写点这种变量，所以突发奇想封装一个，目前感觉还是挺好用的，没出啥bug。。。在表格中也能运用自如。。喜欢的话，可以复制到你自己的项目拿去用，记得点个赞噢

实际使用

代码实现

import { reactive } from 'vue'
import { ElMessageBox, ElMessage } from 'element-plus'
import { isArray } from 'lodash-es'
// 过滤表单
import { filterForm } from '@/utils'

interface SubmitType {
  loading?: string
  params?: any
  successText?: string
  errorText?: string
  message?: string
  title?: string
}

interface SubmitParamsType {
  loadingText?: string
  params?: any
  api: Function
  success?: string
  error?: string
  submitMessage?: string
}

interface UpdateType {
  loading?: string
  params?: any
  api?: Function
  successText?: string
  errorText?: string
}

interface CrudLoadingType {
  [_submitLoading: string]: boolean
}

interface UpdateLoadingType {
  [_updateLoading: string]: boolean
}

const submitDataHook = (context: SubmitType) => {
  const {
    loading = '_submitLoading',
    successText = '操作成功',
    errorText = '操作失败',
    message = '是否进行提交',
    title = '温馨提示'
  } = context
  const submitLoading = reactive({}) as CrudLoadingType
  const submitHook = ({
    params,
    api,
    loadingText = loading,
    success = successText,
    error = errorText,
    submitMessage = message
  }: SubmitParamsType) => {
    return new Promise((resolve, reject) => {
      submitLoading[loadingText as string] = true
      ElMessageBox.confirm(submitMessage, title)
        .then(() => {
          return api(isArray(params) ? params : filterForm(params))
            .then((data) => {
              ElMessage.success(success)
              resolve(data)
              return data
            })
            .catch((res) => {
              reject(res)
              if (res.code === '1' && !res.msg) {
                ElMessage.error(error)
              }
            })
        })
        .catch(() => {
          reject()
          ElMessage.warning('取消操作')
        })
        .finally(() => {
          submitLoading[loadingText as string] = false
        })
    })
  }
  return {
    submitHook,
    submitLoading
  }
}

const updateData = (context: UpdateType) => {
  const { loading = '_updateLoading', successText = '操作成功', errorText = '操作失败' } = context
  const updateLoading = reactive({ [loading]: false }) as UpdateLoadingType
  const updateHook = ({
    params,
    api,
    success = successText,
    error = errorText,
    loadingText = loading
  }: SubmitParamsType) => {
    updateLoading[loadingText] = true
    return api(isArray(params) ? params : filterForm(params))
      .then((data) => {
        ElMessage.success(success)
        return data
      })
      .catch((e) => {
        ElMessage.error(error)
        throw e
      })
      .finally(() => {
        updateLoading[loadingText] = false
      })
  }
  return {
    updateHook,
    updateLoading
  }
}

export { submitDataHook, updateData }
