微信小程序动画之弹出菜单

用微信小程序做了一个动画，效果如上图：

代码：

js：

Page({
  data: {
    isPopping: false,
    animPlus: {},
    animCollect: {},
    animTranspond: {},
    animInput: {},
    animCloud:{},
    aninWrite:{},
  },
  //点击弹出
  plus: function () {
    if (this.data.isPopping) {
      //缩回动画
      this.popp();
      this.setData({
        isPopping: false
      })
    } else if (!this.data.isPopping) {
      //弹出动画
      this.takeback();
      this.setData({
        isPopping: true
      })
    }
  },
  input: function () {
    console.log("input")
  },
  transpond: function () {
    console.log("transpond")
  },
  collect: function () {
    console.log("collect")
  },
  cloud:function(){
    console.log("cloud")
  },
  write: function () {
    console.log("cloud")
  },

  //弹出动画
  popp: function () {
    //plus顺时针旋转
    var animationPlus = wx.createAnimation({
      duration: 400,
      timingFunction: ‘ease-out‘
    })
    var animationcollect = wx.createAnimation({
      duration: 400,
      timingFunction: ‘ease-out‘
    })

      timingFunction: ‘ease-out‘
    })
    var animationCloud = wx.createAnimation({
      duration: 400,
      timingFunction: ‘ease-out‘
    })
    var animationWrite = wx.createAnimation({
      duration: 400,
      timingFunction: ‘ease-out‘
    })
    animationPlus.rotateZ(180).step();
    animationcollect.translate(-90, -100).rotateZ(180).opacity(1).step();
    animationTranspond.translate(-140, 0).rotateZ(180).opacity(1).step();
    animationInput.translate(-90, 100).rotateZ(180).opacity(1).step();
    animationCloud.translate(0, 135).rotateZ(180).opacity(1).step();
    animationWrite.translate(0, -135).rotateZ(180).opacity(1).step();
    this.setData({

      animTranspond: animationTranspond.export(),
      animInput: animationInput.export(),
      animCloud: animationCloud.export(),

    })
  },
  //收回动画
  takeback: function () {
    //plus逆时针旋转
    var animationPlus = wx.createAnimation({
      duration: 400,
      timingFunction: ‘ease-out‘
    })

    })

      timingFunction: ‘ease-out‘
    })
    animationPlus.rotateZ(0).step();
