微信小程序倒计时获取验证码的具体代码,供大家参考,具体内容如下
1、工具类(引用微信小程序提供的工具类)
countdown.js
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` ? options[i] : defaultOptions[i] if (i === `date` && typeof this.options.date !== `object`) { this.options.date = new Date(this.options.date) } if (typeof this.options[i] === `function`) { this.options[i] = this.options[i].bind(this) } } } if (typeof this.options.date !== `object`) { this.options.date = new Date(this.options.date) } } /** * 计算日期差 */ getDiffDate() { let diff = (this.options.date.getTime() - Date.now() + this.options.offset) / 1000 let dateData = { years: 0, days: 0, hours: 0, min: 0, sec: 0, millisec: 0, } if (diff <= 0) { if (this.interval) { this.stop() this.options.onEnd() } return dateData } if (diff >= (365.25 * 86400)) { dateData.years = Math.floor(diff / (365.25 * 86400)) diff -= dateData.years * 365.25 * 86400 } if (diff >= 86400) { dateData.days = Math.floor(diff / 86400) diff -= dateData.days * 86400 } if (diff >= 3600) { dateData.hours = Math.floor(diff / 3600) diff -= dateData.hours * 3600 } if (diff >= 60) { dateData.min = Math.floor(diff / 60) diff -= dateData.min * 60 } dateData.sec = Math.round(diff) dateData.millisec = diff % 1 * 1000 return dateData } /** * 补零 */ leadingZeros(num, length = 2) { num = String(num) if (num.length > length) return num return (Array(length + 1).join(`0`) + num).substr(-length) } /** * 更新组件 */ update(newDate) { this.options.date = typeof newDate !== `object` ? new Date(newDate) : newDate this.render() return this } /** * 停止倒计时 */ stop() { if (this.interval) { clearInterval(this.interval) this.interval = !1 } return this } /** * 渲染组件 */ render() { this.options.render(this.getDiffDate()) return this } /** * 启动倒计时 */ start() { if (this.interval) return !1 this.render() if (this.options.refresh) { this.interval = setInterval(() => { this.render() }, this.options.refresh) } return this } /** * 更新offset */ updateOffset(offset) { this.options.offset = offset return this } /** * 重启倒计时 */ restart(options = {}) { this.mergeOptions(options) this.interval = !1 this.start() return this } }
export default Countdown
2、WXML部分:
{{ c2 || '获取验证码' }}
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, }) }, }) }
