微信小程序实现animation动画

animation1: {}
animation2: {}

touch: function () {
 let animation1 = wx.createAnimation({
  transformOrigin: "50% 50%",
  duration: 1000,
  timingFunction: "ease",
  delay: 0
 });
 animation1.translateX(-app.globalData.windowWidth * 0.7).step({ duration: 1000 });
 this.setData({
  animation1: animation1.export()
 });
 let animation2 = wx.createAnimation({
  transformOrigin: "50% 50%",
  duration: 1000,
  timingFunction: "ease",
  delay: 0
 });
 animation2.opacity(0.7).step({ duration: 1000 });
 this.setData({
  animation2: animation2.export()
 });
}

<view animation="{{animation1}}"></view>
<view animation="{{animation2}}"></view>

<view bindtap="touch"></view>
