微信小程序实现弹出菜单
本文实例为大家分享了微信小程序实现弹出菜单的具体代码，供大家参考，具体内容如下
菜单
代码:
1.index.js
//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

},
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'
})

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(),
})
}
