how to write this javascript function in coffeescript (ajax callbacks)

Question

jQuery(function($) {
  // create a convenient toggleLoading function
  var toggleLoading = function() { $("#loading").toggle() };

  $("#new_post")
    .bind("ajax:loading",  toggleLoading)
    .bind("ajax:complete", toggleLoading)
    .bind("ajax:success", function(event, data, status, xhr) {
      $("#response").html(data);
    });
});

this is my js function (or Simone Carletti's) and I want to transform it to coffeescript, I am having trouble with the last two callbacks, though.

My coffeescript looks like this

jQuery ->
    $("#new_post")
    .bind("ajax:loading",  toggleLoading)
    .bind("ajax:complete", toggleLoading)
    .bind("ajax:success", (event, data, status, xhr) ->
        alert(data)
    .bind("ajax:failure", (event, data, status, xhr) ->
        alert(data)

but I am getting an Error: unclosed INDENT on line 21

thanks in advance

The problem here is simply that you have mismatched parentheses. The line

.bind("ajax:success", (event, data, status, xhr) ->
    alert(data)

never closes the .bind call. Change your code to

jQuery ->
    $("#new_post")
    .bind("ajax:loading",  toggleLoading)
    .bind("ajax:complete", toggleLoading)
    .bind("ajax:success", (event, data, status, xhr) ->
        alert(data))
    .bind("ajax:failure", (event, data, status, xhr) ->
        alert(data))

and it'll work just fine.

pretty show indetion is right, are you sure the last 4 lines of my coffeescript are correct? I wonder if i need any parenthesis or something...

Sorry, I assumed a tab/spaces issue, but on second glance it was a parens issue. I've changed my answer.
