toast.js

import ToastComponent from './toast.vue'
const Toast = {};
// 注册Toast
Toast.install = function (Vue) {
  // 生成一个Vue的子类
  // 同时这个子类也就是组件
  const ToastConstructor = Vue.extend(ToastComponent)
  // 生成一个该子类的实例
  const instance = new ToastConstructor();
  // 将这个实例挂载在我创建的p上
  // 并将此p加入全局挂载点内部
  instance.$mount(document.createElement('p'))
  document.body.appendChild(instance.$el)
  // 通过Vue的原型注册一个方法
  // 让所有实例共享这个方法 
  Vue.prototype.$toast = (msg, duration = 1500) => {
    instance.message = msg;
    instance.visible = true;
    setTimeout(() => {
