Set a bound Shiny input — pz_set_shiny

Uses the input's registered Shiny binding to update the visible control and notify the server. The id is the complete DOM ID, including any module prefix (for example, "mod-text"); it is searched only in the current scope, including the scope element itself. This does not set unbound inputs, action buttons, or file inputs.

Usage

pz_set_shiny_input(ctx, id, value, ..., wait = TRUE)

Arguments

ctx: A paparazzi context.
id: Full DOM ID of a bound Shiny input.
value: Value accepted by the binding's setValue(). Date ranges accept c(start, end) or list(start = ..., end = ...), with ISO date strings. Date-valued sliders accept ISO date strings, converted to JavaScript timestamps. Top-level NULL and atomic NA are rejected.
...: Checked empty; reserved for future use.
wait: If TRUE, call pz_wait_for_shiny_idle() after the change. If FALSE, return immediately after dispatching the change.

Value

ctx, invisibly.

Examples

if (FALSE) { # paparazzi:::examples_run("shiny")
page <- pz_open(pz_example("tasks-app"))

# Each call waits for Shiny to go idle, so the server has seen the value
page |>
  pz_set_shiny_input("title", "Buy milk") |>
  pz_set_shiny_input("priority", "high") |>
  pz_act_click("#add") |>
  pz_expect_text("3 tasks", target = "#summary")
pz_get_attr(page, "data-priority", target = ".task")
pz_close(page)
