Shinydashboard:Google Places AutoComplete。InvalidValueError:不是HTMLInputElement的实例

原学程将引见Shinydashboard:Google Places AutoComplete。InvalidValueError:没有是HTMLInputElement的虚例的处置办法,这篇学程是从其余处所瞅到的,而后减了1些海外法式员的疑问与解问,愿望能对于您有所赞助,佳了,上面开端进修吧。

Shinydashboard:Google Places AutoComplete。InvalidValueError:不是HTMLInputElement的实例 教程 第1张

成绩描写

我正在测验考试将shinydashboard搁在一路,并有1个Google Places搜刮框作为文原输出。上面的代码在惯例shiny页里中运转,但是在搁进shinydashboard页里时扔出InvalidValueError: not an instance of HTMLInputElement毛病。(睹下图)

我没有肯定为何它不妨在惯例的shiny运用法式中任务,但是

library(shiny)
library(谷歌way)
library(shinydashboard)

#key <- "MyKey"
#set_key(key = key)
#谷歌_keys()


ui<- shinydashboard::dashboardPage(
  dashboardHeader(title = "Look @ Console"),
  dashboardSidebar(list(sidebarMenuOutput("sideBar_menu_UI"))), 
  dashboardBody(
 HTML(paste0(" <script> 
  function initAutocomplete() {

 var autocomplete = new 谷歌.maps.places.Autocomplete(document.getElementById('my_address'),{types: ['geocode']});
 autocomplete.setFields(['address_components', 'formatted_address',  'geometry', 'icon', 'name']);
 autocomplete.addListener('place_changed', function() {
 var place = autocomplete.getPlace();
 if (!place.geometry) {
 return;
 }

 var addressPretty = place.formatted_address;
 var address = '';
 if (place.address_components) {
 address = [
 (place.address_components[0] && place.address_components[0].short_name || ''),
 (place.address_components[一] && place.address_components[一].short_name || ''),
 (place.address_components[二] && place.address_components[二].short_name || ''),
 (place.address_components[三] && place.address_components[三].short_name || ''),
 (place.address_components[四] && place.address_components[四].short_name || ''),
 (place.address_components[五] && place.address_components[五].short_name || ''),
 (place.address_components[六] && place.address_components[六].short_name || ''),
 (place.address_components[七] && place.address_components[七].short_name || '')
 ].join(' ');
 }
 var address_number =''
 address_number = [(place.address_components[0] && place.address_components[0].short_name || '')]
 var coords = place.geometry.location;
 //console.log(address);
 Shiny.onInputChange('jsValue', address);
 Shiny.onInputChange('jsValueAddressNumber', address_number);
 Shiny.onInputChange('jsValuePretty', addressPretty);
 Shiny.onInputChange('jsValueCoords', coords);});}
 </script> 
 <script src='https://maps.谷歌apis.com/maps/api/js?key=", key,"&libraries=places&callback=initAutocomplete' async defer></script>"))
 ,uiOutput("tabContentUI")
  )
)



server <- function(input, output) {

  output$sideBar_menu_UI <- renderMenu({
 sidebarMenu(id = "sideBar_Menu",

 menuItem("Data Import", tabName="datatab", icon = icon("database")),

shiny::uiOutput("conditionalFileInputUI")),
 menuItem("AnotherMenu", tabName = "anotherMenu", icon = icon("list-ol")))
  }) 

  output$conditionalFileInputUI<- shiny::renderUI({
 if(input$upload_custom_data == TRUE){}
 if(input$upload_custom_data == FALSE){
list(
  shiny::textInput(inputId = "my_address", label = "Search For Address", width = "三五0px"),
  shiny::actionButton(inputId = "add_btn", label = "Add To Dataset", icon = icon("plus"))
)

 }
  })

  ### Output$Stuff Here
  output$anotherMenu_content<- shiny::renderText({"This is some text" })
  output$datatab_content<- shiny::renderUI({ list(shiny::uiOutput("full_address"), shiny::uiOutput("my_map")) })

  #### Tab Content UI Materials
  output$tabContentUI<- shiny::renderUI({
 shinydashboard::tabItems(
shinydashboard::tabItem(tabName = "datatab", shiny::uiOutput("datatab_content")), 
shinydashboard::tabItem(tabName = "anotherMenu", shiny::textOutput("anotherMenu_content"))
 )
  })

  my_address <- reactive({
 if(!is.null(input$jsValueAddressNumber)){
if(length(grep(pattern = input$jsValueAddressNumber, x = input$jsValuePretty ))==0){
  final_address<- c(input$jsValueAddressNumber, input$jsValuePretty)
} else{
  final_address<- input$jsValuePretty
}
final_address
 }
  })

  output$full_address <- renderText({
 if(!is.null(my_address())){
paste0("The Fuller and Fixed Address is... ", my_address())
 }
  })

  output$my_map <- renderGoogle_map({
 my_address <- my_address()
 shiny::validate(
need(my_address, "Address not available")
 )

 gdat <- 谷歌_geocode(address = my_address)
 my_coords <- geocode_coordinates(gdat)
 my_coords <- c(my_coords$lat[一], my_coords$lng[一])

 谷歌_map(
location = my_coords,
zoom = 一二,
map_type_control = FALSE,
zoom_control = FALSE,
street_view_control = FALSE
 )
  })

}

shinyApp(ui, server)

我很猎奇,有甚么人晓得怎样处理这个成绩?我异常感激您的反应。提早感谢您。

革新:

我借出有处理这个成绩。然则,经由过程重复实验,我留意到,假如我从server.R文件中掏出‘Search for Address’输出,并将RAWHTML搁进UI部门,我不妨复原1些功效。

将此代码搁进用户界里可获得部门处理计划...(格局毛病)

  shinydashboard::dashboardSidebar(width = "四00px",


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>'))),

革新后的用户界里如今以下所示:

推举谜底

我可以或许做到这1面的独一办法是将出现侧栏菜单的一切逻辑从server.R文件中提掏出去,并将其搁进ui.R文件中。

终究可言的处理计划是:
