Create an input control for entry of numeric values
numericInput(
inputId,
label,
value,
min = NA,
max = NA,
step = NA,
width = NULL,
...,
updateOn = c("change", "blur")
)
The input
slot that will be used to access the value.
Display label for the control, or NULL
for no label.
Initial value.
Minimum allowed value
Maximum allowed value
Interval to use when stepping between min and max
The width of the input, e.g. '400px'
, or '100%'
;
see validateCssUnit()
.
Ignored, included to require named arguments and for future feature expansion.
A character vector specifying when the input should be
updated. Options are "change"
(default) and "blur"
. Use "change"
to
update the input immediately whenever the value changes. Use "blur"
to
delay the input update until the input loses focus (the user moves away
from the input), or when Enter is pressed (or Cmd/Ctrl + Enter for
textAreaInput()
).
A numeric input control that can be added to a UI definition.
A numeric vector of length 1.
