Detailed explanation of the animation effect code example of animation heartbeat developed by WeChat applet

This article mainly introduces the animation heartbeat animation effect of the WeChat mini program in detail. It has certain reference value. Interested friends can refer to it.

The example of this article is to share with you the WeChat mini program. The program develops animation heartbeat animation for your reference. The specific content is as follows

1. WeChat applet develops animation heartbeat animation

In the wxml file:

<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 file:

// 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://www.tuicool.com/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. WeChat displays countdown

In wxml file:

<!--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>

In js file:

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: &#39;活动已结束&#39;, 
  }); 
  this.setData({ 
   countDownDay: &#39;00&#39;, 
   countDownHour: &#39;00&#39;, 
   countDownMinute: &#39;00&#39;, 
   countDownSecond: &#39;00&#39;, 
  }); 
  } 
 }.bind(this), 1000); 
 }, 
 //cell事件处理函数 
 bindCellViewTap: function (e) { 
 var id = e.currentTarget.dataset.id; 
 wx.navigateTo({ 
  url: &#39;../babyDetail/babyDetail?id=&#39; + id 
 }); 
 } 
})
