微信小程序实现弹出菜单

//index.js//获取应用实例var app = getApp()Page({ data: { isPopping: false,//是否已经弹出 animationPlus: {},//旋转动画 animationcollect: {},//item位移,透明度 animationTranspond: {},//item位移,透明度 animationInput: {},//item位移,透明度 //我的博客:http://blog.csdn.net/qq_31383345 //CSDN微信小程序开发专栏:http://blog.csdn.net/column/details/13721.html }, onLoad: function () { }, //点击弹出 plus: function () { if (this.data.isPopping) {  //缩回动画  popp.call(this);  this.setData({  isPopping: false  }) } else {  //弹出动画  takeback.call(this);  this.setData({  isPopping: true  }) } }, input: function () { console.log("input") }, transpond: function () { console.log("transpond") }, collect: function () { console.log("collect") }})//弹出动画function popp() { //plus顺时针旋转 var animationPlus = wx.createAnimation({ duration: 500, timingFunction: 'ease-out' }) var animationcollect = wx.createAnimation({ duration: 500, timingFunction: 'ease-out' }) var animationTranspond = wx.createAnimation({ duration: 500, timingFunction: 'ease-out' }) var animationInput = wx.createAnimation({ duration: 500, timingFunction: 'ease-out' }) animationPlus.rotateZ(180).step(); animationcollect.translate(-100, -100).rotateZ(180).opacity(1).step(); animationTranspond.translate(-140, 0).rotateZ(180).opacity(1).step(); animationInput.translate(-100, 100).rotateZ(180).opacity(1).step(); this.setData({ animationPlus: animationPlus.export(), animationcollect: animationcollect.export(), animationTranspond: animationTranspond.export(), animationInput: animationInput.export(), })}//收回动画function takeback() { //plus逆时针旋转 var animationPlus = wx.createAnimation({ duration: 500, timingFunction: 'ease-out' }) var animationcollect = wx.createAnimation({ duration: 500, timingFunction: 'ease-out' }) var animationTranspond = wx.createAnimation({ duration: 500, timingFunction: 'ease-out' }) var animationInput = wx.createAnimation({ duration: 500, timingFunction: 'ease-out' }) animationPlus.rotateZ(0).step(); animationcollect.translate(0, 0).rotateZ(0).opacity(0).step(); animationTranspond.translate(0, 0).rotateZ(0).opacity(0).step(); animationInput.translate(0, 0).rotateZ(0).opacity(0).step(); this.setData({ animationPlus: animationPlus.export(), animationcollect: animationcollect.export(), animationTranspond: animationTranspond.export(), animationInput: animationInput.export(), })}
