Answer 1

可以通过调用wx.hideTabBar和wx.showTabBar隐藏或展示底部的tabbar。
例

index.js

Page({
  data: {
    show: false
  },
  showPopup() {
    wx.hideTabBar({ animation: true })
    setTimeout(() => { this.setData({ show: true }); }, 200);
  },
  onClose() {
    this.setData({ show: false });
    setTimeout(() => { wx.showTabBar({ animation: true }) }, 300);
  },
})

index.wxml

<van-cell title="展示弹出层" is-link bind:click="showPopup" />
<van-popup show="{{ show }}" bind:close="onClose" position="bottom" custom-style="height: 20%;" closeable close-icon-position="top-right">
</van-popup>

index.json

{
  "usingComponents": {
    "van-popup": "/miniprogram_npm/@vant/weapp/popup/index",
    "van-cell": "/miniprogram_npm/@vant/weapp/cell/index"
  }
}
