实现的效果
第一种方法(利用微信小程序的animation)
wxml部分
<!--pages/myRecode/myRecode.wxml-->
<view class="myRecode">
<view class="recode" bindtouchstart='recodeClick' bindtouchend='recodeEnd'>
<text>长按</text>
<view class="ripple"></view>
<view class="ripple" animation="{{animationData1}}"></view>
<view class="ripple" animation="{{animationData2}}"></view>
</view>
</view>wxss部分
/* pages/myRecode/myRecode.wxss */
.myRecode{
padding-top:500rpx;
text-align: center;
box-sizing: border-box;
}
.myRecode .recode{
display: inline-block;
width:200rpx;
height:200rpx;
background: #EBB128;
border-radius: 50%;
text-align: center;
color:#fff;
line-height: 200rpx;
position: relative;
}
.ripple{
position: absolute;
top:0;
left:0;
right:0;
bottom:0;
border-radius: 50%;
border:2px solid #F6F1CC;

Page({
/**
* 页面的初始数据
*/
data: {
animationData1: "",
animationData2: "",
animationStatus: false
},
/**
* 生命周期函数--监听页面加载
*/
onLoad: function(options) {
},
/**
* 生命周期函数--监听页面初次渲染完成
*/
onReady: function() {
},
/**
* 生命周期函数--监听页面显示
*/
onShow: function() {
},
/**

*/
onHide: function() {
},
/**

*/
onUnload: function() {

//事件函数
animationFun:function(animationData){
if(!this.data.animationStatus){
return
}
var animation = wx.createAnimation({
duration: 1000
})
animation.opacity(0).scale(2, 2).step();
this.setData({
[`${animationData}`]: animation.export()
})
},
animationEnd: function (animationData) {
var animation = wx.createAnimation({
duration: 0
})
animation.opacity(1).scale(1, 1).step();
this.setData({
[`${animationData}`]: animation.export()
})
},
recodeEnd: function() {
//动画1结束
var animation1 = wx.createAnimation({
duration: 0
})
animation1.opacity(1).scale(1, 1).step();
//动画2结束
var animation2 = wx.createAnimation({
duration: 0
})
animation2.opacity(1).scale(1, 1).step();
this.setData({
animationData1: animation1.export(),
animationData2: animation2.export(),
animationStatus: false
})
},
recodeClick: function() {
this.setData({
animationStatus: true
})
this.animationFun('animationData1')
setTimeout(()=>{
this.animationFun('animationData2')
},500)
setTimeout(() => {
this.animationRest()
}, 1000)
},
animationRest: function() {
//动画重置
this.animationEnd('animationData1')
setTimeout(()=>{
this.animationEnd('animationData2')
},500)
setTimeout(() => {
if (this.data.animationStatus) {
this.recodeClick()
}
}, 100)
}
})第二种方法（纯wxss控制）
