[Lift] Re: Simple Ajax call to server side function
This same thing is also touched by http://reviewboard.liftweb.net/r/184/
(driven by Kris' post)
Do you agree with these following statements:
1. The SHtml Ajax function should return JsCmd
2. The SHtml non Ajax function should return a Unit instead of Any
(unless there are compelling reasons to keep Any)
If so I could probably make the adjustments today since I'm on that
defect anyways.

Originally, the function returned Any... and this led to problems (people
returning HTML, Strings, etc.) It turns out that 95% of the time, you want
to do something to tell the user that the server did something (unless the
function sends a message to a CometActor), so using the type-system to make
sure Ajax functions returned JsCmds was the right answer.

Returning Any returns the value of the last expression in the function.
Returning Unit always returns the Unit instance. In some places (I think
when processing Ajax forms) we take the return value from the functions and
try to determine if they are meant as JavaScript or somesuch to be sent back
to the browser.

[Lift] Re: Simple Ajax call to server side function
Very well then. If you do recall the rationale for keeping Any for non
Ajax function, please let me/us know about it or add a comment in the
code as I get the feeling that this will raise up again in the future.

Re: [Lift] Re: Simple Ajax call to server side function
Sorry for not being more precise.
If I understood you, you said there are times where a function whose return
value is *not* used, but still code broke when the expected type was changed to
the more correct Unit. Is that not what you were referring to when you said you
don't remember why but it broke a lot of code?

to do something to tell the user that the server did something

the
function sends a message to a CometActor), so using the type-system
to
make
sure Ajax functions returned JsCmds was the right answer.

It is awkward having to add a JsCmd even when I don't need it.

Hi all,
I want to create a link which when clicked calls a server

No need for JavaScript callback.
I tried with no success:
SHtml.a(() = {serverSideFunction(t.text)}, t)
Any idea how can I accomplish that will be appreciated.
Thanks,

Originally, the function returned Any... and this led to problems (people
returning HTML, Strings, etc.) It turns out that 95% of the time, you want
