這篇文章主要為大家詳細(xì)介紹了微信小程序自定義對話框彈出和隱藏動畫，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了微信小程序自定義對話框彈出和隱藏動畫的具體代碼，供大家參考，具體內(nèi)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 () {
 // 顯示遮罩層
 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 () {
 // 隱藏遮罩層
 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;
}
