本文实例为大家分享了微信小程序开发animation心跳动画，供大家参考，具体内容如下

1、微信小程序开发animation心跳动画

wxml文件中：

<view class="bottomViewItem"> <view class="bottomMiddleHeaderView" bindtap="voteClick" data-id="value"> <view class="bottomMiddleHeaderItem" animation="{{animationMiddleHeaderItem}}"> <!-- 心跳 --> <view class="bottomMiddleHeaderItemSubView"> <image src="/images/detail_vote_heart.png" style="width:32rpx; height:32rpx;" animation="{{animationMiddleHeaderItem}}"></image> </view> <!-- 投票文字 --> <view class="bottomMiddleHeaderItemSubView">投票</view> </view> </view> </view>

js文件中：

// 页面渲染完成 onReady: function () { var circleCount = 0; // 心跳的外框动画 this.animationMiddleHeaderItem = wx.createAnimation({ duration:1000, // 以毫秒为单位 /** * http://cubic-bezier.com/#0,0,.58,1 * linear 动画一直较为均匀 * ease 从匀速到加速在到匀速 * ease-in 缓慢到匀速 * ease-in-out 从缓慢到匀速再到缓慢 * * http:///articles/neqMVr * step-start 动画一开始就跳到 100% 直到动画持续时间结束 一闪而过 * step-end 保持 0% 的样式直到动画持续时间结束 一闪而过 */ timingFunction: 'linear', delay: 100, transformOrigin: '50% 50%', success: function (res) { } }); setInterval(function() { if (circleCount % 2 == 0) { this.animationMiddleHeaderItem.scale(1.15).step(); } else { this.animationMiddleHeaderItem.scale(1.0).step(); } this.setData({ animationMiddleHeaderItem: this.animationMiddleHeaderItem.export() }); circleCount++; if (circleCount == 1000) { circleCount = 0; } }.bind(this), 1000); },

2、微信显示倒计时

wxml文件中：

<!--倒计时 --> <view class="countDownTimeView countDownAllView" > <view class="voteText countDownTimeText">{{countDownDay}}天</view> <view class="voteText countDownTimeText">{{countDownHour}}时</view> <view class="voteText countDownTimeText">{{countDownMinute}}分</view> <view class="voteText countDownTimeText">{{countDownSecond}}秒</view> </view>

js文件中：

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 = 1505540080 - 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 }); } })
