冉冉升起的如银的炊烟，那更古沉默永不停息的小溪，那驮着夕阳缓缓独行的老牛，一方方秧田像棋盘格子，绿绒绒的秧苗，织成一幅幅地毯，远远地伸向天际；丛丛绿树掩映着青砖红瓦的房屋。春天，故乡的松树林依然郁郁苍苍，映山红却已开遍山丘。
本文实例为大家分享了微信小程序自定义对话框弹出和隐藏动画的具体代码，供大家参考，具体内容如下
index.js
//index.js
var app = getApp();
let animationShowHeight = 300;
Page({
data:{
animationData:"",
showModalStatus:false,
imageHeight:0,
imageWidth:0
},
imageLoad: function (e) {
this.setData({imageHeight:e.detail.height,imageWidth:e.detail.width});
},
showModal: function () {
// 显示遮罩层
var animation = wx.createAnimation({
duration: 200,
timingFunction: "linear",
delay: 0
})
this.animation = animation
animation.translateY(animationShowHeight).step()
this.setData({
animationData: animation.export(),
showModalStatus: true
})
setTimeout(function () {
animation.translateY(0).step()
this.setData({
animationData: animation.export()
})
}.bind(this), 200)
},
hideModal: function () {
// 隐藏遮罩层
var animation = wx.createAnimation({
duration: 200,
timingFunction: "linear",
delay: 0
})
this.animation = animation;
animation.translateY(animationShowHeight).step()
this.setData({
animationData: animation.export(),
})
setTimeout(function () {
animation.translateY(0).step()
this.setData({
animationData: animation.export(),
showModalStatus: false
})
}.bind(this), 200)
},
onShow:function(){
let that = this;
wx.getSystemInfo({
success: function(res) {
animationShowHeight = res.windowHeight;
}
})
},
})
index.wxml
<!--index.wxml-->
<view class="container-column">
<view animation="{{animationData}}" class="container-column buydes-dialog-container" wx:if="{{showModalStatus}}">
<view class="buydes-dialog-container-top" bindtap="hideModal"></view>
<view class="container-column buydes-dialog-container-bottom">
<block wx:for="{{['操作1','操作2','操作3','取消']}}" wx:for-index="index" wx:key="key" wx:for-item="item">
<view bindtap="hideModal" class="buydes-dialog-container-bottom-item" >{{item}}</view>
</block>
</view>
</view>
<image bindtap="showModal" bindload="imageLoad" style="width:{{imageWidth}}px;;height:{{imageHeight}}px;" src="../pro1.jpg"/>
</view>
index.wxss
.buydes-dialog-container{
width: 100%;
height: 100%;
justify-content: space-between;
background-color:rgba(15, 15, 26, 0.7);
position: fixed;
z-index: 999;
}
.buydes-dialog-container-top{
flex-grow: 1;
}
.buydes-dialog-container-bottom{
display: flex;
flex-grow: 0;
}
.buydes-dialog-container-bottom-item{
padding:24rpx;
display: flex;
justify-content: center;
border-bottom: 1rpx solid #eeeeee;
}
