微信小程序动画之下拉刷新动画的具体代码，供大家参考，具体内容如下

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; }
