本文实例为大家分享了微信小程序实现商城倒计时的具体代码,供大家参考,具体内容如下
index.html:
<view class="countDownTimeView pull-left countDownAllView text-left"> <text>倒计时:</text> <text class="voteText countDownTimeText">{{countDownHour}}</text> : <text class="voteText countDownTimeText">{{countDownMinute}}</text> : <text class="voteText countDownTimeText">{{countDownSecond}}</text> </view>
util.js :
const formatTime = date => { const year = date.getFullYear() const month = date.getMonth() + 1 const day = date.getDate() const hour = date.getHours() const minute = date.getMinutes() const second = date.getSeconds() return [year, month, day].map(formatNumber).join('/') + ' ' + [hour, minute, second].map(formatNumber).join(':') } const formatNumber = n => { n = n.toString() return n[1] ? n : '0' + n } module.exports = { formatTime: formatTime }
index.js:
var util = require('../../utils/util.js'); //调用微信小程序中时间格式化的js Page: ({ data: { countDownHour: 0, //倒计时 -时 countDownMinute: 0, //倒计时 -分 countDownSecond: 0, //倒计时-秒 }, // 页面渲染后 执行 onLoad: function () { //设置倒计时时间,1s变换一次 var interval = setInterval(function () { var d = new Date(); //获取系统日期和时间 var nowHour = d.getHours(); //小时 var nowMinutes = d.getMinutes(); //分 var nowSeconds = d.getSeconds(); //秒 // 显示在倒计时中的小时位 var hour = 24 - nowHour; // 显示在倒计时中的分钟位 var minutes = 60 - nowMinutes; // 显示在倒计时中的秒数 var seconds = 60 - nowSeconds; //当小时、分钟、秒都为0时,活动结束,倒计时显示为00:00:00 if (hour == 0 && minutes == 0 && seconds == 0) { clearInterval(interval); wx.showToast({ title: '活动已结束', }); console.log(totalSecond); this.setData({ countDownHour: '00', countDownMinute: '00', countDownSecond: '00', }); } //当小时位、分钟位、秒位小于10时,用字符串拼接的方式显示,例如:06:08:02 if (hour < 10) { hour = "0" + hour; } if (minutes < 10) { minutes = "0" + minutes; } if (seconds < 10) { seconds = "0" + seconds; } this.setData({ countDownHour: hour, countDownMinute: minutes, countDownSecond: seconds, }); }.bind(this), 1000); }, })
最终实现效果图如下:
