JS（这里的JS我是直接用别人的，CSDN有下，自己处理了下样式）

let animationShowHeight = 300;  
Page({  
  data: {  
    showModalStatus: false,  
    imageHeight: 0,  
    imageWidth: 0  
  },  
  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), 0)  
  },  
  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;  
      }  
    })
