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")
  },

    //plus顺时针旋转
