添加单选按钮以选择Shiny中的DataTable行 [英] Adding radiobutton to select a DataTable row in Shiny
问题描述
我需要添加radiButtons以选择Data中的行,即所选的单选按钮应传递给输入。
我无法在DT中使用内置行选择。我确实需要使用单选按钮来选择行。
这就是需要的内容:
I need to add radiButtons to select rows in Data, i.e. the radiobutton choosen should be passed to input. I cannot use built in row selection in DT. I really need to use radiobuttons to select the row. This is what is wanted:
使用 https://yihui.shinyapps.io/DT-radio/ 我可以选择列。
Es:
Using https://yihui.shinyapps.io/DT-radio/ I am able to select COLUMNS. Es:
library(shiny)
library(DT)
shinyApp(
ui = fluidPage(
title = 'Radio buttons in a table',
DT::dataTableOutput('foo'),
verbatimTextOutput("test")
),
server = function(input, output, session) {
m = matrix(
c(round(rnorm(24),1), rep(3,12)), nrow = 12, ncol = 3, byrow = F,
dimnames = list(month.abb, LETTERS[1:3])
)
for (i in seq_len(nrow(m))) {
m[i, 3] = sprintf(
if_else(i == 1,
'<input type="radio" name="%s" value="%s" checked="checked"/>',
'<input type="radio" name="%s" value="%s"/>'),
"C", month.abb[i]
)
}
m=t(m)
output$foo = DT::renderDataTable(
m, escape = FALSE, selection = 'none', server = FALSE,
options = list(dom = 't', paging = FALSE, ordering = FALSE),
callback = JS("table.rows().every(function() {
var $this = $(this.node());
$this.attr('id', this.data()[0]);
$this.addClass('shiny-input-radiogroup');
});
Shiny.unbindAll(table.table().node());
Shiny.bindAll(table.table().node());")
)
output$test <- renderPrint(str(input$C))
}
)
天真地,我试图删除m = t(m)并将行更改为回调中的列,但这不起作用,因为示例中的回调函数正在添加
Naively, I tried to remove m=t(m) and changing rows to columns in the callback. This is not working because the callback function in the example is adding class and id to the last , which have no counterpart for column.
有什么想法吗?
推荐答案
一个肮脏的解决方法可能是将整个数据表与 C
div 中> id和 shiny-input-radiogroup
类:
A "dirty" fix could be to wrap the whole datatable in a div
with the C
id and the shiny-input-radiogroup
class:
shinyApp(
ui = fluidPage(
title = 'Radio buttons in a table',
tags$div(id="C",class='shiny-input-radiogroup',DT::dataTableOutput('foo')),
verbatimTextOutput("test")
),
server = function(input, output, session) {
m = matrix(
c(round(rnorm(24),1), rep(3,12)), nrow = 12, ncol = 3, byrow = F,
dimnames = list(month.abb, LETTERS[1:3])
)
for (i in seq_len(nrow(m))) {
m[i, 3] = sprintf(
if_else(i == 1,
'<input type="radio" name="%s" value="%s" checked="checked"/>',
'<input type="radio" name="%s" value="%s"/>'),
"C", month.abb[i]
)
}
m
output$foo = DT::renderDataTable(
m, escape = FALSE, selection = 'none', server = FALSE,
options = list(dom = 't', paging = FALSE, ordering = FALSE)
)
output$test <- renderPrint(str(input$C))
}
)
