微信小程序实现倒计时60s获取验证码

class Countdown {
constructor(options = {}) {
Object.assign(this, {
options, 
})
this.__init()
}
/**
* 初始化
*/
__init() {
this.page = getCurrentPages()[getCurrentPages().length - 1]
this.setData = this.page.setData.bind(this.page)
this.restart(this.options)
}
/**
* 默认参数
*/
setDefaults() {
return {
date: `June 7, 2087 15:03:25`, 
refresh: 1000, 
offset: 0, 
onEnd() {}, 
render(date) {}, 
}
}
/**
* 合并参数
*/
mergeOptions(options) {
const defaultOptions = this.setDefaults()
for (let i in defaultOptions) {
if (defaultOptions.hasOwnProperty(i)) {
this.options[i] = typeof options[i] !== `undefined` "htmlcode">

<view class="weui-cell__ft">
 <view class="weui-vcode-btn" bindtap="vcode">{{ c2 || '获取验证码' }}</view>
</view>



3、JS部分:


import $wuxCountDown from 'countdown/countdown'
export {
 $wuxCountDown, 
}
import { $wuxCountDown } from '../../components/wux'
 vcode: function () {
 if (this.c2 && this.c2.interval) return !1
 this.c2 = new $wuxCountDown({
 date: +(new Date) + 60000,
 onEnd() {
 this.setData({
 c2: '重新获取验证码',
 })
 },
 render(date) {
 const sec = this.leadingZeros(date.sec, 2) + ' 秒后重发 '
 date.sec !== 0 && this.setData({
 c2: sec,
 })
 },
 })
 }
