render_focus(element, value \\ %{})

View Source

Sends a focus event given by element and returns the rendered result.

The element is created with element/3 and must point to a single element on the page with a phx-focus attribute in it. The event name given set on phx-focus is then sent to the appropriate LiveView (or component if phx-target is set accordingly). All phx-value-* entries in the element are sent as values. Extra values can be given with the value argument.

It returns the contents of the whole LiveView or an {:error, redirect} tuple.

Examples

{:ok, view, html} = live(conn, "/thermo")

assert view
       |> element("#inactive")
       |> render_focus() =~ "Tap to wake"
