在App.vue中

<style  scoped>
@import './common.css';
</style>

在main.js中

import tools from './tools'
Vue.prototype.tool = tools

tools.js

export default { 
  //显示加载框---使用方法，例如：this.tool.showLoading('正在加载',this,'1')
  showLoading (message, el, type) { 
    var html = '';
    html += '<i class="mui-spinner mui-spinner-white"></i>';
    html += '<p class="text">' + (message || "数据加载中") + '</p>';
    //遮罩层
    var mask = document.getElementsByClassName("mui-show-loading-mask");
    if (mask.length == 0) { 
      mask = document.createElement('div');
      mask.classList.add("mui-show-loading-mask");
      // console.log(type)
      // 自己添加内容...start

      document.body.appendChild(mask);
