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
{{ title }}
{{ content }}
{{ cancelText }}
{{ confirmText }}
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!')
}
