Passing options to JS function with Amber

I'm trying to write the equivalent of:

$( "#draggable" ).draggable({ axis: "y" });

in Amber smalltalk.

My guess was: '#draggable' asJQuery draggable: {'axis' -> 'y'} but that's not it.

Solution

  • Not working on vanilla 0.9.1, but working on master at least last two months ago is:

    '#draggable' asJQuery draggable: #{'axis' -> 'y'}

    and afaict this is the recommended way.

    P.S.: #{ 'key' -> val. 'key2' -> val } is the syntax for inline creation of HashedCollection, which is implemented (from the aforementioned two-month ago fix) so that only public (aka enumerable) properties are the HashedCollection keys. Before the fix also all the methods were enumerable, which prevented to use it naturally in place of JavaScript objects.
