Question

我正在尝试将shinydashboard放在一起，并使用Google地方信息搜索框作为文本输入。下面的代码在常规的shiny页中运行，但是将其放入InvalidValueError: not an instance of HTMLInputElement时会引发shinydashboard错误。（请参见下图）

我不确定为什么它可以在常规shiny应用程序中运行，但是为什么不能在shinydashboard内部运行它们。

错误的屏幕截图：

我很好奇，是否有人知道如何解决？感谢您的反馈。先感谢您。

更新：

我仍然没有解决这个问题。但是，通过反复试验，我注意到，如果我从server.R文件中取出“搜索地址”输入并将原始HTML放在UI部分中，则可以得到一些功能。

将此代码放到用户界面中可获得部分解决方案...（道歉）

  shinydashboard::dashboardSidebar(width = "400px",


list(shinydashboard::sidebarMenuOutput(outputId = "sideBar_menu_UI"),


 HTML('<div class="form-group shiny-input-container"> <label for="my_address">Type An Address</label> <input id="my_address" type="text" class="form-control" value=""/> </div>'))),

更新后的UI现在如下所示：

我能够做到这一点的唯一方法是，将呈现sidebarMenu的所有逻辑从server.R文件中提取出来并将其放入ui.R文件中。

最终的工作方案是：

library(googleway)
library(shinydashboard)

#set_key(key = mygoogleapikey)
#google_keys()
