How do I submit a form in jQuery async?

In mootools I would do something like $('form_id').send({success:function(res){....}}); What is the parallel syntax in jQuery?

Another words:
How would I put my form data (assume id='bob') into the following code

$.ajax({
  type: 'POST',
  url: url,
  data: data,
  success: success,
  dataType: dataType
});
