This time I will bring you a detailed explanation of the use of the vue global prompt box component. What are the precautions when using the vue global prompt box component. The following is a practical case. Let’s take a look.
This article introduces you to a vue global prompt box component. The specific code is as follows:

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(() => { instance.visible = false; }, duration); } } export default Toast
