vue中elementUI的Loading.service函数的封装

import { Loading } from 'element-ui';
 
const loadOption={fullscreen: true ,lock: true, text: 'Loading', spinner: 'el-icon-loading', background: 'rgba(0, 0, 0, 0.7)'}
 
let loadingInstance;
 
export default class loadEvents {
    constructor(vueThis){
        this.vm = vueThis ;  //vue中的this  也可以不用
    }
    open(){
        loadingInstance = Loading.service(loadOption);
    }
    close(){
        loadingInstance.close();
    }
}
//loads.open();loading效果出现；loads.close();关闭loading效果
