闪亮数据表上的单选按钮,带有 data.frame / data.table
Radio Buttons on Shiny Datatable, with data.frame / data.table
几乎是 this example 的复制粘贴(我认为它取代了 SO 上的其他一些答案)除了我正在尝试使用 data.table 而不是矩阵。我无法弄清楚为什么它不起作用。
library(shiny)
library(DT)
shinyApp(
ui = fluidPage(
title = 'Radio buttons in a table',
DT::dataTableOutput('foo'),
verbatimTextOutput('sel')
),
server = function(input, output, session) {
m = data.table(
month1 = month.abb,
A = '1',
B = '2',
C = '3',
QWE = runif(12)
)
m[, A := sprintf(
'<input type="radio" name="%s" value="%s"/>',
month1, m[, A]
)]
m[, B := sprintf(
'<input type="radio" name="%s" value="%s"/>',
month1, m[, B]
)]
m[, C := sprintf(
'<input type="radio" name="%s" value="%s"/>',
month1, m[, C]
)]
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(i, tab, row) {
var $this = $(this.node());
$this.attr('id', this.data()[0]);
$this.addClass('shiny-input-radiogroup');
});
Shiny.unbindAll(table.table().node());
Shiny.bindAll(table.table().node());")
)
output$sel = renderPrint({
str(sapply(month.abb, function(i) input[[i]]))
})
}
)
问题与行名有关。您有一个额外的行名列,可以向其中添加所有闪亮的属性,但它不是单选按钮,它只是文本,所以它会中断(尽管它应该会抛出错误)。
这是一个工作版本:
