将其在vue目录中用一个js文件存起来，哪个页面需要弹窗时引入

import eduAlert from ‘@/js/alert.js‘

在方法中就可以使用了

alertmethos(){
      // eduAlert.showAlert("我很好的的哈哈",null,true);
      // eduAlert.showAlert("我很好的的哈哈",function(){
      //   alert(1111);
      // },true);
      // eduAlert.showAlert("我很好的的哈哈",function(){
      //   alert(1111);
      // },false);
      // alert(1111)
      eduAlert.eduToast("自定义弹窗时长弹窗",2000)
}
