You're almost there. The second parameter to ajaxCheckbox is a function that
gets called on the server when the checkbox changes:
SHtml.ajaxCheckbox(thing.isActive, (toggled: Boolean) =>
{thing.setActive(toggled); Noop})
The Noop is needed because ajaxCheckbox expects a Boolean => JsCmd function.
(I can't find a good reason for it needing a JsCmd though... Shouldn't it
just be Boolean => Any or better yet Boolean => Unit?) Howver, you can
replace "thing.setActive(toggled)" with whatever code you want to run when
the checkbox is toggled. Here, "toggled" contains the state of the checkbox.
Likewise ajaxSelect:
val daysOfWeek = List("Monday", "Tuesday", "Wednesday", "Thursday",
"Friday",
"Saturday", "Sunday").map(x => (x, x))
SHtml.ajaxSelect(daysOfWeek, Full("Monday"), (opt: String) =>
{thing.setDayOfWeek(opt); Noop})
The second parameter is the default value. The "opt" in the third parameter
will correspond to the selected day.
