Question

I want the javascript code to be

someFunction(42, function onSuccess() {}, function onFailure() {})

Notice that while defining onSuccess and onFailure, I want to name them (not because it’s necessary, but because it documents the code). However, I can’t get coffeescript to generate this code.

For anonymous function passing I can do

someFunction(42,
->
// onsuccess code
->
// onfailure code
)

But when I tried to give names to those functions, it didn’t translated as expected to Javascript

someFunction(42,
onSuccess : ->
// onsuccess code
onFailure : ->
// onfailure code
)

translates to

someFunction(42, { onSuccess : function () {}, onFailure : function () {} })

Another try

someFunction(42,
onSuccess ->
// onsuccess code
onFailure ->
// onfailure code
)

translates to

someFunction(42, onSuccess(function () {}), onFailure(function () {}))

How do I do this?

Answer 1

does this work?

someFunction 42, (onSuccess = -> ), onFailure = ->

http://jsfiddle.net/keith_nicholas/Qdzph/

generates..

somefunction(42, (onSuccess = function() {}), onFailure = function() {});

and, in the coffeescript faq, it talks about why you can’t generate named functions :-
