简易的效果

下面放代码：

js：

var animation = wx.createAnimation({})var i = 1;Page({ data: {  donghua: true,  left1: Math.floor(Math.random() * 250 + 1),  left2: Math.floor(Math.random() * 250 + 1),  left3: Math.floor(Math.random() * 250 + 1),  left4: Math.floor(Math.random() * 250 + 1),  left5: Math.floor(Math.random() * 250 + 1),  left6: Math.floor(Math.random() * 250 + 1),  left7: Math.floor(Math.random() * 250 + 1),  left8: Math.floor(Math.random() * 250 + 1), }, //动画 donghua: function () {  var that = this;  setTimeout(function () {   animation.translateY(800).step({    duration: 1600,    timingFunction: 'ease'   })   that.setData({    ["animationData" + i]: animation.export()   })   i++;  }.bind(that), 200)  if (i < 9) {   setTimeout(function () {    that.donghua()   }.bind(that), 200)  } else {   i = 0;   animation.translateY(-800).step({    duration: 10,   })   setTimeout(function () {    for (var y = 0; y < 9; y++) {     that.setData({      ["animationData" + y]: animation.export()     })     that.setData({      ["animationData" + y + '.actions[0].animates[0].args[0]']: 0     })    }   }.bind(that), 1500)  } }, onPullDownRefresh: function () {  wx.showNavigationBarLoading();  this.donghua();  wx.stopPullDownRefresh(); },})

wxml：

<!-- 动画 --><block wx:if="{{donghua}}"> <view class='donghua'>  <image bindtap='hua' style='left:{{left1}}px' animation="{{animationData1}}" src='../../images/1.png'></image>  <image bindtap='hua' style='left:{{left2}}px' animation="{{animationData2}}" src='../../images/2.png'></image>  <image bindtap='hua' style='left:{{left3}}px' animation="{{animationData3}}" src='../../images/3.png'></image>  <image bindtap='hua' style='left:{{left4}}px' animation="{{animationData4}}" src='../../images/1.png'></image>  <image bindtap='hua' style='left:{{left5}}px' animation="{{animationData5}}" src='../../images/2.png'></image>  <image bindtap='hua' style='left:{{left6}}px' animation="{{animationData6}}" src='../../images/3.png'></image>  <image bindtap='hua' style='left:{{left7}}px' animation="{{animationData7}}" src='../../images/1.png'></image>    <image bindtap='hua' style='left:{{left8}}px' animation="{{animationData8}}" src='../../images/2.png'></image> </view></block>

wxss：

image{ margin-top: -150rpx; width: 40rpx; height: 40rpx; margin-left: 5%; position: absolute; }
