<script>
  export default {
    data() {
      return {
        list: [],
        animation1: ""
      }
    },
    onShow() {
      var animation1 = wx.createAnimation({
        duration: 3000,
        timingFunction: 'ease',
      })
      animation1.translate(30).step()
      this.animation1 = animation1.export();

      var animation2 = wx.createAnimation({
        duration: 3000,
        timingFunction: 'ease',
      });
      animation2.translate(30).step()
      this.list = [{
        animationData: animation2.export(),
        word: "v-for中设置的动画",
      }];
    }
  }
</script>
