写一个Vue Popup组件
组件长这样
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 name="modal-pop"> <div class="wrap" v-show="visible"> <div class="modal"> <h3>{{ title }}</h3> <p>{{ content }}</p> <div class="btns"> <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!') }
