全局封装组件处理并发请求不连续的loading

import { Loading } from 'element-ui'

let loadingCount = 0
let loading

const startLoading = () => {
  loading = Loading.service({
    lock: true,
    text: '拼命加载中...', // 可以自定义文字
    spinner: 'el-icon-loading', // 自定义加载图标类名
    background: 'rgba(1, 1, 1, 0.8)'// 遮罩层背景色
  })
}

const endLoading = () => {
  loading.close()
}

export const showLoading = () => {
  if (loadingCount === 0) {
    startLoading()
  }
  loadingCount += 1
}

export const hideLoading = () => {
  if (loadingCount <= 0) {
    return
  }
  loadingCount -= 1
  if (loadingCount === 0) {
    endLoading()
  }
}
