[Rails] Re: return JSON in AJAX

Check here: http://api.jquery.com/jQuery.post/

There's an example titled "Example: Posts to the test.php page and gets contents which has been returned in json format" about half way down the page.

hello guys, I'm trying to make a ajax request and return some data from
my controller, but how I do it to call the JSON in my JS after the
request ?

controller task

def create

    @task = Task.create( :project_id => params[ :project_id ], :name =>
params[ :task ] )

    if @task.valid?
      @return = { :task => @task.name, :project_id => @task.project_id }
    else
      @return = { :error => "Ocorreu um erro inesperado. Tente
novamente." }
    end

    return ActiveSupport::JSON.encode( @return )

  end

view index - JS

$( "#tasks_form" ).submit( function( e ) {

          e.preventDefault();
          var task = $( this).find( "textarea" ).val();

          $.post( "<%= url_for :controller => :task, :action => :create
%>", { task: task, project_id: <%= @project_id %> }, function( e ) {

          }, "json");

      } );

Thank you
