Using loading in element, loading

Preface:
      When loadding is used in element, it is not convenient to call it in js, so it is encapsulated here.
First write a loading.js file:

import { Loading } from 'element-ui';
 
let loadingCount = 0;
let loading;
 
const startLoading = () => {
  loading = Loading.service({
    lock: true,
    text: '加载中……',
    background: 'rgba(0, 0, 0, 0.7)'
  });
};
 
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();
  }
};

transfer:
 

import { showLoading, hideLoading } from './loading';
 
showLoading();//打开加载中
 
hideLoading();//关闭加载中
