原生挪用:

//该js文件中到场这一行代码
window.slider = slider;
//参数1,dom,参数2:时候
slider.slideDown(document.queryselector(),time);
slider.slideUp(document.queryselector(),time);

vue.js挪用:

//该js文件到场这一行代码
export default slider;

main.js中引入:
import slider from 'slider.js';
//绑定到Vue实例原型上
Vue.prototype.slider = slider;

//组件中挪用
this.slider(this.$refs,time);
