【中文标题】将数据导出到 SQL DB 时闪亮禁用操作按钮 x 秒【英文标题】:Shiny disabling the actionbutton for x seconds while exporting data to SQL DB 【发布时间】:2018-06-07 13:31:24 【问题描述】:我有一个包含动态数据的handsontable,我正在使用带有闪亮提交按钮的 sqlSave 代码将它上传到 MSSQL DB。
但是,我可以通过 bot 找到任何会禁用操作按钮的功能,比如说 10 秒。我尝试了 shinyjs::disable 和 withProgress, incProgress 的东西,但它们都不起作用。
谢谢,
dbhandle <- odbcDriverConnect('driver=SQL Server;server=....;database=...;trusted_connection=true')
withProgress(
sqlSave(dbhandle, dat = some data),
tablename = "Budget_Tool",
rownames = F, append = T, verbose = T, fast = F, colnames = F, safer =
T), value = 1,
style = "notification", message = "Submitting, please wait..")
--------------------
actionButton("submit", "Submit", class = "btn-primary",
style="color: #fff; background-color: #337ab7; border-
color: #2e6da4; font-size: 20px;"),

【参考方案1】:当您在操作功能之前和之后集成禁用和启用时,它或多或少是直截了当的。
这里是一个示例 sn-p:
library(shiny)
library(shinyjs)
ui <- shinyUI(
shiny::fluidPage(
useShinyjs(), # Set up shinyjs
actionButton(inputId = "start", label = "start")
)
)
server <- shinyServer(function(input, output)
actionFunction = function()
shinyjs::disable("start")
# Replace actual code instead
withProgress(message = 'Calculation in progress',
detail = 'This may take a while...', value = 0,
for (i in 1:15)
incProgress(1/15)
Sys.sleep(0.25)
)
shinyjs::enable("start")
# Run action function on button click
onclick("start", actionFunction())
)
shinyApp(ui,server)

【参考方案2】:我通过使用隐藏和显示来修复它;
observeEvent(input$submit,
hide('submit', animType = "fade", time = 5)
asd <- as.data.frame(cbind(Department = rv$data[,2], Cost_Summary_Key =
rv$data[,1], Calculated_Budget = rowSums(rv$data[,3:14]))) %>%
left_join(CSK_Budget, c("Department", "Cost_Summary_Key"))
asd <- asd %>% mutate(Deviation = (as.numeric(Budget_2017) - rowSums(rv$data[,3:14])))
x <- c()
for (i in 1:nrow(asd))
if(asd[i,5] >= -0.05)
x[i] <- TRUE else x[i] <- FALSE
moment <- substr(Sys.time(), 1, 10)
moment2 <- substr(Sys.time(), 12, 19)
personel <- input$userName
if( all(x))
dbhandle <- odbcDriverConnect('driver=SQL Server;server=...;database=...._SQL;trusted_connection=true')
withProgress(
sqlSave(dbhandle, dat = (cbind(melt(rv$data, na.rm = F, varnames = c(Department, Cost_Summary_Key), as.is = F), Year = "2017",
Time_Stamp1 = moment, Time_Stamp2 = moment2, User = personel)),
tablename = ".....",
rownames = F, append = T, verbose = T, fast = F, colnames = F, safer = T), value = 1,
style = "notification", message = "Submitting, please wait..")
js_string <- 'alert("Succes!!");'
session$sendCustomMessage(type='jsCode', list(value = js_string))
showNotification("Thanks, your response was submitted successfully!", duration = 5, type = "warning")
else showNotification("Check Your Budget Items !!", duration = 3, type = "warning")
odbcCloseAll()
show('submit', animType = "slide", time = 1)
)
