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。
