Coffeescript使用jQuery Ajax调用外部文档准备功能生成JS

Question

Can anyone tell me why this coffee script:

$ ->  
  $('#btnLogin').live 'click', ->
    $.ajax
      url: 'user/login'
      type: 'POST'
      data: 'Username=' + $('#username').val() + '&password=' + $('#password').val()
      success: (data, status, request) ->
        alert data

Generates this javascript with the ajax call outside the document ready method?

(function() {
  $(function() {
    return $('#btnLogin').live('click', function() {});
  });
  $.ajax({
    url: 'user/login',
    type: 'POST',
    data: 'Username=' + $('#username').val() + '&password=' + $('#password').val(),
    success: function(data, status, request) {
      return alert(data);
    }
  });
}).call(this);

I you aren't familiar with the site: http://js2coffee.org/ It's a great resource for testing out these issues. You can convert code between coffeescript from javascript very easily. I use it often when I run into these issues.

This was actually a problem with tab spacing in visual studio, I changed the tab spacing while I was working on the file and it ballsed everything up. I just deleted all the spacing and tabbed in on every line and then it generated the js I wanted
