启动app第一次从列表页进入商品页在点返回上一页就会报错

启动app第一次从列表页进入商品页在点返回上一页就会报错错误提示是下面的图片



然后再第3次或者是第4次进入商品页再返回上一页也就是列表页有提示一个新的错误请看下图  然后在app里面浏览就在返回就不提示


就启动app的第一次进去返回提示错误和第3次或者第4次就提示这两次以后就不提示了
列表页打开的方式是
  justep.Shell.showPage("detail", {
            goodsID : data.getValue("goods_id"),
        });


商品页关闭的方式是：{operation:'window.close'}  创建页面自带的关闭方式

请问这个是怎么回事？

浏览器打开 F12  
看下控制台的完整报错信息是什么？？
哪行代码报错的？？

看上去是调用某个对象是 空 导致的！

w页面先模型编译一下！ 有没有报错信息呢？
看上去是页面编译有问题！需要页面调整正确，不要报错

是模式几打包的？？ 保证app中资源和服务器是同步的！

可以先使用appLoader 打包测试下是否正常？？
手机系统自带浏览器访问是否正常？

appLoader 测试没问题  模式1打包的

appLoader 测试没问题  模式1打包的

模式1打包 是异步更新资源的！可能客户端和服务器资源不同步导致的！（app中资源是旧的）
1.APP 多运行 重启 几次试试

2.试试模式3打包正常吗？这个是调试开发用的！可以实时更新studio 修改的资源！
