      }
    ]
  },

      

解決方案一：把 tabBar配置中的 "pagePath": "pages/zhuye/zhuye", 換成 配置為首頁的pages/splash/splash 就可以了；(簡單說就是有底部導航欄的那個稱為首頁，首頁就應該放到第一個位置上，初始值也是第一個)

<navigator url="../zhuye/zhuye" open-type="switchTab" >
           <button class="btn" bindtap="start" wx:if="{{index == movies.length - 1}}" >立即體驗</button>
      </navigator>
      

//相容詳情傳回首頁底部消失的問題
      wx.switchTab({
          url :  self.indexPagePath,//url路徑
          success(res){

          },
          fail(){ //容錯處理
              wx.navigateBack({
                  delta: 1,
                  fail:function(){
                      wx.reLaunch({
                          url: self.indexPagePath //url路徑
                      })
                  }
              })
          }
      })
