How do pass extra parameters from jQuery to Rails?

Question

I need to pass an extra parameter :mobilejs => true from jQuery to a rails controller. How do I do that?

This...

var settings  = $.extend{  'url': url,
      'data' : '{mobilejs:true}',
      'success' : callback || function () {},
      'dataType' : 'script'
      }, options || {});
 $.ajax(settings);

creates this response from the server

Answer 1

'data' : '{mobilejs:true}',

Has to be:

'data' : {mobilejs:true},
