这篇文章主要介绍了微信小程序显示倒计时功能,结合实例形式分析了微信小程序针对给定时间的倒计时功能相关界面显示与逻辑运算操作技巧,需要的朋友可以参考下
本文实例讲述了微信小程序显示倒计时功能。分享给大家供大家参考,具体如下:
微信小程序中显示倒计时:
index.wxml:
<view class='countdown'>剩:<text style='color:#6B4EFD'> {{countDownDay}} </text> 天 <text style='color:#6B4EFD'>{{countDownHour}} </text> <text style='color:#6B4EFD'>{{countDownMinute}} </text> <text style='color:#6B4EFD'>{{countDownSecond}} </text> </view>
index.js:
Page( { data: { windowHeight: 654, maxtime: "", isHiddenLoading: true, isHiddenToast: true, dataList: {}, countDownDay: 0, countDownHour: 0, countDownMinute: 0, countDownSecond: 0, }, //事件处理函数 bindViewTap: function() { wx.navigateTo( { url: '../logs/logs' }) }, onLoad: function() { this.setData( { windowHeight: wx.getStorageSync( 'windowHeight' ) }); }, // 页面渲染完成后 调用 onReady: function () { var totalSecond = Date.parse(new Date("2018/12/12")) / 1000 - Date.parse(new Date()) / 1000; var interval = setInterval(function () { // 秒数 var second = totalSecond; // 天数位 var day = Math.floor(second / 3600 / 24); var dayStr = day.toString(); if (dayStr.length == 1) dayStr = '0' + dayStr; // 小时位 var hr = Math.floor((second - day * 3600 * 24) / 3600); var hrStr = hr.toString(); if (hrStr.length == 1) hrStr = '0' + hrStr; // 分钟位 var min = Math.floor((second - day * 3600 *24 - hr * 3600) / 60); var minStr = min.toString(); if (minStr.length == 1) minStr = '0' + minStr; // 秒位 var sec = second - day * 3600 * 24 - hr * 3600 - min*60; var secStr = sec.toString(); if (secStr.length == 1) secStr = '0' + secStr; this.setData({ countDownDay: dayStr, countDownHour: hrStr, countDownMinute: minStr, countDownSecond: secStr, }); totalSecond--; if (totalSecond < 0) { clearInterval(interval); wx.showToast({ title: '活动已结束', }); this.setData({ countDownDay: '00', countDownHour: '00', countDownMinute: '00', countDownSecond: '00', }); } }.bind(this), 1000); }, //cell事件处理函数 bindCellViewTap: function (e) { var id = e.currentTarget.dataset.id; wx.navigateTo({ url: '../babyDetail/babyDetail?id=' + id }); } })
运行结果如下图所示:
希望本文所述对大家微信小程序开发有所帮助。
