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 -->

<view class='donghua'>
<image bindtap='hua' style='left:{{left1}}px' animation="{{animationData1}}" src='../../images/1.png'></image>
