[Lift] Re: JsCmd to Actual Javascript
Well you can see thr Raw JavaScript with FireBug for example. On Lift side take a look on LiftServlet.scala convertAnswersToCometResponse. From you can see this: val ret = ar.response.toJavaScript(session, ar.displayAll) toJavaScript is a method of the internal XmlOrJsCmd class which you can find in CometActor.scala. Besides that, you don't need to explicitly use CmdPair as you can just say partialUpdate(jsCmd1 jsCmd2 ...)

Bar actually running the code and looking in the browser, how do I do this? JsCmd obviously has some sort of serialization method that is called before it is sent to the browser, but it is not readily apparent to me what it is. Thanks!

[Lift] Re: JsCmd
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.

What about selecting the day of the week from an ajaxSelect and updating
dayOfWeek. Or, finally, updating a text field on blur and setting the

Examples would really help.
I am pretty desperate to have this done today, and several hours of
playing with various combinations has left me befuddled. Doesn't help
that it's 4 AM.
Any and all help very greatly appreciated.

[Lift] Re: JsCmd
The return type is JsCmd because 80% of the time the Ajax command causes
some update top be sent to the browser. So, the special case is a Noop
(sometimes I do an implicit Unit - Noop) and the default case is returning
the code to be rendered in the browser.
