微信小程序自定义对话框+弹出和隐藏动画详解

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

   
    
        
        
          
              {{item}}
          
        
    

    

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;
}

效果图：

 

下面是实际开发中的效果图，没有源码，但是原理和上面的是一样的，通过上面的DEMO学习加上平常的CSS基础，完全可以做出下面的效果
