引用文件

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
   if (type !== '2' && type) {
    var winHig = document.documentElement.clientHeight;
    if (el.$refs.nav) {
     var heightNav = el.$refs.nav.offsetHeight;
     var heightFix = el.$refs.fixed.offsetHeight;
     if (type === '1') {
      var loHig = winHig - heightNav - heightFix + 'px'
     } else {
      loHig = winHig - heightFix + 'px'
     }
     mask.style.top = heightFix + 'px'
     mask.style.height = loHig
    }
   }
   // 自己添加内容...End
   document.body.appendChild(mask);
   mask.addEventListener("touchmove", function (e) { e.stopPropagation(); e.preventDefault(); });
  } else {
   mask[0].classList.remove("mui-show-loading-mask-hidden");
  }
  //加载框
  var toast = document.getElementsByClassName("mui-show-loading");
  if (toast.length == 0) {
   toast = document.createElement('div');
   toast.classList.add("mui-show-loading");
   toast.classList.add('loading-visible');
   document.body.appendChild(toast);
   toast.innerHTML = html;
   toast.addEventListener("touchmove", function (e) { e.stopPropagation(); e.preventDefault(); });
  } else {
   toast[0].innerHTML = html;
   toast[0].classList.add("loading-visible");
  }
 },

 //隐藏加载框----使用方法,例如:this.tool.hideLoading();
 hideLoading (callback) {
  var mask = document.getElementsByClassName("mui-show-loading-mask");
  var toast = document.getElementsByClassName("mui-show-loading");
  if (mask.length > 0) {
   mask[0].classList.add("mui-show-loading-mask-hidden");
  }
  if (toast.length > 0) {
   toast[0].classList.remove("loading-visible");
   callback && callback();
  }
