写一个Vue Popup组件

主要有标题、内容、按钮个数、按钮颜色、按钮文案这些可配置项

期望的调用方式一

不需要等待用户二次确认

import Modal from 'common/components/modal' handleModal() { Modal({ title: '赚取收益？', content: '根据您的授权金额和计息天数计算得出(还未到账)。实际以到账金额为准。', confirmText: '我知道了' }) }

期望的调用方式二

需要等待用户二次确认

import Modal from 'common/components/modal' async handleModal() { await Modal({ title: '确定现在申请结束吗？', content: '申请后预计1-5个工作日可退出', cancelColor: '#ff7400', confirmColor: '#000', showCancel: true }) }

模板长这样

common/components/modal/modal.vue

这里用 transition 来包裹动画，填好配置参数就行了

handleConfirm() 二次确认事件我们不放这里实现，具体原因后面会讲

<template> <transition> <div v-show="visible"> <div> <h3>{{ title }}</h3> <p>{{ content }}</p> <div> <span v-if="showCancel" @click="visible = false" :style="`color: ${cancelColor}`">{{ cancelText }}</span> <span @click="handleConfirm()" :style="`color: ${confirmColor}`">{{ confirmText }}</span> </div> </div> </div> </transition> </template> <style lang="less"> @import './modal.less'; </style>

定义好 props 参数列表，visible 作为组件内部状态控制弹框打开关闭

export default { props: [ 'title', 'content', 'showCancel', 'cancelColor', 'cancelText', 'confirmText', 'confirmColor' ], data() { return { visible: false } } }

组件包装

common/components/modal/index.js

先利用 vue 的 extend 拿到刚编写的模板

import Vue from 'vue' const ModalConstructor = Vue.extend(require('./modal.vue')) const Modal = (opts = {}) => { let _m = new ModalConstructor({ el: document.createElement('div') }) } export default Modal

配置好默认参数，并将 visible 状态打开以显示弹框，最终插入页面

import Vue from 'vue' const ModalConstructor = Vue.extend(require('./modal.vue')) const Modal = (opts = {}) => { let _m = new ModalConstructor({ el: document.createElement('div') }) _m.title = opts.title || '提示' _m.content = opts.content || '' _m.showCancel = opts.showCancel || false _m.cancelText = opts.cancelText || '取消' _m.cancelColor = opts.cancelColor || '#000' _m.confirmText = opts.confirmText || '确定' _m.confirmColor = opts.confirmColor || '#ff7400' _m.visible = true document.body.appendChild(_m.$el) } export default Modal

用户点击二次确认事件后，为了方便组件外部捕捉，这里使用 Promise 包装回调事件

这样 handleConfirm() 放在这里实现是不是就方便很多了

import Vue from 'vue' const ModalConstructor = Vue.extend(require('./modal.vue')) const Modal = (opts = {}) => { let _m = new ModalConstructor({ el: document.createElement('div') }) _m.title = opts.title || '提示' _m.content = opts.content || '' _m.showCancel = opts.showCancel || false _m.cancelText = opts.cancelText || '取消' _m.cancelColor = opts.cancelColor || '#000' _m.confirmText = opts.confirmText || '确定' _m.confirmColor = opts.confirmColor || '#ff7400' _m.visible = true document.body.appendChild(_m.$el) return new Promise(resolve => { return (_m.handleConfirm = () => { _m.visible = false resolve() }) }) } export default Modal

最终长这样

import Modal from 'common/components/modal' async handleModal() { await Modal({ title: '确定现在申请结束吗？', content: '申请后预计1-5个工作日可退出', cancelColor: '#ff7400', confirmColor: '#000', showCancel: true }) console.log('用户确认了！') }
