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!')

}
